A panorama of Brazilian social housing research: scope, gaps and intersections

Um panorama da pesquisa sobre Habitação de Interesse Social no Brasil: abrangência, lacunas e interseções

Abstrac

Social Housing (SH) is investigated worldwide, especially in emerging economies. However, SH literature demonstrates that there are still barriers to achieving the real benefits of those programmes. Brazilian SH programmes have positively reduced housing deficits and the vulnerability of low-income populations. However, studies developed in Brazil also reveal the negative impacts of SH. Investigating the reason for the recurrence of negative impacts is fundamental to gaining a stronger understanding of the causes and scope of SH problems. Moreover, state-of-the-art studies may support the development of actions to mitigate those problems. Thus, this study aims to categorise the major topics studied on SHs, identify and evaluate SH main failures and impacts, analyse intersections of topics, and understand their scope. A systematic review and literature mapping were applied to analyse SH studies. Although evidence emphasises significant advances in SH production, results demonstrate the intersecting panorama of occurrences that cause negative impacts and stress the need for investments and the implementation of housing public policies aligned with societal interests to improve SH.

Resumo

A Habitação de Interesse Social (HIS) é amplamente investigada mundialmente, especialmente nas economias emergentes. No entanto, a literatura sobre HIS demonstra que ainda existem barreiras para alcançar benefícios reais desses programas. Os programas de HISs brasileiros reduziram positivamente o déficit habitacional e a vulnerabilidade social da população de baixa renda. No entanto, estudos desenvolvidos no Brasil também revelam os impactos negativos da HISs. Investigar a razão da recorrência de impactos negativos é fundamental para maior entendimento da causa e abrangência dos problemas. Além disso, estudos do estado da arte podem auxiliar com o desenvolvimento de ações para mitigar impactos de HISs. Assim, a pesquisa visa categorizar os principais tópicos estudados sobre HIS, identificar e avaliar as deficiências dos HISs, analisar interseções de tópicos, e compreender a sua abrangência. Uma revisão sistemática e mapeamento sistemático da literatura foram aplicados para analisar e mapear os estudos de HIS. Embora as evidências enfatizem avanços significativos na produção de HISs, resultados demonstram o panorama interseccional de ocorrências que causam impactos negativos, ressaltam a necessidade de investimentos e a implementação de políticas públicas de habitação alinhadas aos interesses da sociedade para melhorar HISs.

Introduction

Social Housing (SH) programmes are widely studied in different fields worldwide, revealing that barriers exist to achieving real benefits from SH programmes, mostly in emerging economies. There is scientific research evidence that SH often fails to deliver the intended socio-economic benefits and may trigger negative impacts on society (Buckley; Kallergis; Wainer, 2016BUCKLEY, R. M.; KALLERGIS, A.; WAINER, L. The emergence of large-scale housing programs: Beyond a public finance perspective. Habitat International, Housing the Planet: Evolution of Global Housing Policies, v. 54, p. 199-209, 2016.; Gustavsson; Elander, 2016GUSTAVSSON, E.; ELANDER, I.

Computers, Environment and Urban Systems, v. 59, p. 1-10, 2016.).

Brazilian SH policies began with significant efforts in 1964 through the National Housing Bank policy, which lasted until 1985, as a response to the housing crisis in relation to accelerated urbanisation (Cardoso; Mello; Jaenisch, 2015CARDOSO, A. L.; MELLO, I. de Q. E.; JAENISCH, S. T. A implementação do Programa Minha Casa Minha Vida na Região Metropolitana do Rio de Janeiro: agentes, processos e contradições. Em: AMORE, C. S.; SHIMBO, L.

Confins, Revista Franco-Brasilera de Geografia , v. 42, 2019.). In 2003, although extinct in 2019, the Ministry of Cities coordinated and managed the National Urban Development Policy. Under this ministry, in 2009, the Brazilian government launched an SH programme called ‘My House My Life’ (MCMV, ‘Minha Casa Minha Vida’ in Portuguese) (Loureiro; Macário; Guerra, 2015LOUREIRO, M. R.; MACÁRIO, V.; GUERRA, P. H. Legitimidade e efetividade em arranjos institucionais de políticas públicas: O programa minha casa minha vida.

Characterisation of representative building typologies for social housing projects in Brazil and its energy performance. Energy Policy , v. 87, p. 524-541, 2015.). The MCMV programme aimed to reduce the housing deficit, improve the living conditions of vulnerable people, and increase economic growth (Tubelo et al., 2018TUBELO, R. et al. Cost-effective envelope optimisation for social housing in Brazil’s moderate climates zones. Building and Environment , v. 133, p. 213-227, 2018.; Acolin; Hoek-Smit; Eloy, 2019ACOLIN, A.; HOEK-SMIT, M. C.; ELOY, C. M.

Bulletin of Latin American Research, v. 40, n. 1, p. 84-99, Jan. 2021.). In 2019, the federal government announced a new programme called Casa Verde e Amarela (CVeA) (Depieri; Ramos, 2020DEPIERI, L.; RAMOS, P. Austeridade e pandemia: perspectivas para as cidades brasileiras. Ponto-e-Vírgula: Revista de Ciências Sociais, v. 27, p. 135-150, 2020.), and in 2023, the new government re-launched the MCMV.

The beneficiaries of MCMV are classified according to the income levels1 1 Federal Savings BankBrazilian currencyFaixa1 (income of up to R$ 1,800.00);Faixa1.5 (income up to R $ 2,600.00), considered lower-income families, andFaixa2 (income up to R $ 4,000.00);Faixa3 (income of up to R $ 7,000.00). or Faixas2 2 Values converted on 03-03-2023. 1 Real/BRL=0,192171USD. Brazilian central bank: https://www.bcb.gov.br/conversao. that include: Faixa 1 (income up to USD 345,91); Faixa 1.5 (income up to USD 499,64), considered lower-income families; and Faixa 2 (income up to USD 768,68) as well as Faixa 3 (income of up to USD 1.345,19), considered middle-income families. Three architectural typologies of MCMV use repetitive models across the national territory, with the following types:

  1. single-family homes;

  2. vertical multifamily buildings of four to five floors; and

  3. vertical multifamily buildings with elevators (Ferreira, 2012FERREIRA, J. S. W. Produzir casas ou construir cidades? Desafios para um novo Brasil Urbano Parâmetros de qualidade para a implementação de projetos habitacionais e urbanos. Gestão & Tecnologia de Projetos, v. 8, n. 2, 2012. ).

Despite the effectiveness in reducing the housing deficit, in Brazil, studies on SH also present negative impacts, mostly on urban and neighbourhood scales, rather than buildings and units (Tubelo et al., 2018TUBELO, R. et al. Cost-effective envelope optimisation for social housing in Brazil’s moderate climates zones. Building and Environment , v. 133, p. 213-227, 2018.). Most of SH is characterised by socio-spatial segregation conditions (Andrade, 2015ANDRADE, L. S. É possível transformar em cidade a anticidade? Crítica ao urbanismo de empreendimentos do PMCMV.

High delinquency rates in Brazil’s Minha Casa Minha Vida housing program: Possible causes and necessary reforms. Habitat International, v. 83, p. 99-110, 2019.). However, the localisation of SHs may trigger negative impacts for residents associated with social, environmental, and economic issues (Rufino et al., 2015RUFINO, M. B. C. et al. A produção do Programa PMCMV na Baixada Santista: habitação de interesse social ou negócio imobiliário? Em: AMORE, C. S.; SHIMBO, L. Z.; RUFINO, M. B. C. (ed.). Minha Casa... E a Cidade? Avaliação do Programa Minha Casa Minha Vida em seis estados brasileiros . Rio de Janeiro: Letra Capita, 2015. ; Vicentim; Kanashiro, 2016VICENTIM, T. N.; KANASHIRO, M. Análise do comércio e dos serviços nos empreendimentos do Programa Minha Casa, Minha Vida (PMCMV): estudo de caso do Residencial Vista Bela - Londrina, PR. Ambiente Construído , Porto Alegre, v. 16, n. 4, p. 227-250, out,/dez. 2016.). Investments are needed in such existing SH to reduce these negative impacts (Kowaltowski et al., 2021KOWALTOWSKI, D. C. C. K. et al. Housing transformation in search of well-being. In: ENCONTRO NACIONAL DE CONFORTO NO AMBIENTE CONSTRUÍDO, 16.; ENCONTRO LATINO-AMERICANO DE CONFORTO NO AMBIENTE CONSTRUÍDO, 12., Palmas, 2021. Anais [...] Palmas, 2021.; Muianga et al., 2021MUIANGA, E. A. D. et al. Critical analysis of housing condition impacts on residents’ well-being and social costs. Gestão & Tecnologia de Projetos , v. 16, n. 4, p. 33-66, out. 2021.).

A substantial volume of studies on Brazilian SH exists (Muianga; Kowaltowski, 2022MUIANGA, E. A. D.; KOWALTOWSKI, D. C. C. K. Mapping of Brazilian social housing studies: state of the art. In: ENCONTRO NACIONAL DE TECNOLOGIA DO AMBIENTE CONSTRUÍDO, 19.,Canela, 2022. Anais […] Canela, 2022.). These studies cover different fields of knowledge, such as architecture, construction, geography, history, economics, and social science. However, there is a lack of a consolidated understanding of research developed so far. Understanding SH problems from different fields and knowledge may contribute to mapping how these studies relate to each other, and how they address SH problems. Furthermore, the consolidation of research may contribute to the diffusion of a broader knowledge on the subject. Therefore, the SH literature must be analysed to evaluate the main failures and impacts of SH problems and consequences. Identifying cause and effect is essential to develop actions to mitigate existing problems in SH through evidence. Thus, two questions guided this research's development: what are the main failures and impacts of SH in Brazil? What are the main actions presented by the conducted studies?

Thus, the research aims to consolidate and categorise issues related to SH studies. The research also aims to identify and assess SH impacts (positive and negative) and analyse the intersections of SH issues with state-of-the-art knowledge. The research contributes a visual panorama of SH issues that may be applied to develop actions for SH upgrading. An organised knowledge base on SH research in Brazil is presented as an additional contribution.

Method

The study combined two Systematic Review (SR) methodologies:

  1. a Systematic Literature Review (SLR); and

  2. a Systematic Mapping Study (SMS) or Systematic Literature Mapping (SLM).

The purpose of SLRs is to gather empirical studies related to a specific research question to analyse, synthesise, and interpret evidence (Kitchenham et al., 2009KITCHENHAM, B. et al. Systematic literature reviews in software engineering: a systematic literature review. Information and Software Technology, v. 51, n. 1, p. 7-15, 2009.; Okoli, 2015OKOLI, C. A guide to conducting a standalone systematic literature review. Communications of the Association for Information Systems, v. 37, n. 43, p. 879-910, 2015.; Koç, 2015KOÇ, H. Methods in designing and developing capabilities: a systematic mapping study. In: WORKING CONFERENCE ON THE PRACTICE OF ENTERPRISE MODELLING, 8., Valencia, 2015. Proceedings [...] Valencia, 2015.; Cahyo, 2021CAHYO, W. N. Finding novelty of research with Systematic Literature Mapping (SLM). Journal of Physics: Conference Series, v. 1764, n. 1, p. 012186, Feb. 2021.). SMS seeks to identify, collect, and analyse relevant studies on a topic, as well as categorise, synthesise and structure a research area (Yañez-Figueroa; Ramírez-Montoya; García-Peñalvo, 2016YAÑEZ-FIGUEROA, J. A.; RAMÍREZ-MONTOYA, M. S.; GARCÍA-PEÑALVO, F. J. Systematic mapping of the literature: social innovation laboratories for the collaborative construction of knowledge from the perspective of open innovation. In: INTERNATIONAL CONFERENCE ON TECHNOLOGICAL ECOSYSTEMS FOR ENHANCING MULTICULTURALITY, 4., Salamanca, 2016. Proceedings [...] Salamanca, 2016.; Kaur; Kaur Chahal; Saini, 2022KAUR, R.; KAUR CHAHAL, K.; SAINI, M. Understanding community participation and engagement in open source software Projects: a systematic mapping study. Journal of King Saud University - Computer and Information Sciences, v. 34, n. 7, p. 4607-4625, jul. 2022.).

The SLR and SMS were developed to identify and analyse new research on SH in Brazil, covering diverse study fields. Snowballing techniques were applied to complement the study sample (Wohlin, 2014WOHLIN, C. Guidelines for snowballing in systematic literature studies and a replication in software engineering. In: INTERNATIONAL CONFERENCE ON EVALUATION AND ASSESSMENT IN SOFTWARE ENGINEERING, 18., London, 2014. Proceedings […] London, 2014.; Fabbri et al., 2016FABBRI, S. et al. Improvements in the StArt tool to better support the systematic review process. In: INTERNATIONAL CONFERENCE ON EVALUATION AND ASSESSMENT IN SOFTWARE ENGINEERING, 20., New York, 2016. Proceedigns […] New York, 2016.). Quantitative and qualitative analyses were applied in the final sample and presented through visual and descriptive results.

Research data were retrieved through the 'StArt' software. 'StArt' stands for “State of the Art”, developed by LaPES (Laboratory of Research on Software Engineering) from the Federal University of São Carlos (UFSCar) in Brazil. The 'StArt' software allows users to search for evidence in the scientific literature and automate coding processes through qualitative and quantitative methods (Bhattacherjee, 2012BHATTACHERJEE, A. Social science research: principles, methods, and practice. 2nd. ed. Florida: University of South Florida, 2012.; Fabbri et al., 2012FABBRI, S. et al. Managing Literature reviews information through visualization. In: INTERNATIONAL CONFERENCE ON ENTERPRISE INFORMATION SYSTEMS, 14., Wrockaw, 2012. Proceedings […]Wroclaw: SCITEPRESS, 2012., 2016FABBRI, S. et al. Improvements in the StArt tool to better support the systematic review process. In: INTERNATIONAL CONFERENCE ON EVALUATION AND ASSESSMENT IN SOFTWARE ENGINEERING, 20., New York, 2016. Proceedigns […] New York, 2016.). The method considers a group of keywords applied in the protocol in the research title, abstract, and the paper´s keywords for scoring analysis (Fabbri et al., 2012FABBRI, S. et al. Managing Literature reviews information through visualization. In: INTERNATIONAL CONFERENCE ON ENTERPRISE INFORMATION SYSTEMS, 14., Wrockaw, 2012. Proceedings […]Wroclaw: SCITEPRESS, 2012.). Studies with high scores should be accepted, and studies with low scores and at least one citation may have a manual analysis, while studies with low scores and no citation should be excluded (Fabbri et al., 2016FABBRI, S. et al. Improvements in the StArt tool to better support the systematic review process. In: INTERNATIONAL CONFERENCE ON EVALUATION AND ASSESSMENT IN SOFTWARE ENGINEERING, 20., New York, 2016. Proceedigns […] New York, 2016.).

Research procedure

The SR process was developed following four steps(Barat et al., 2017BARAT, S. et al. A model-based approach to systematic review of research literature. In: INNOVATIONS IN SOFTWARE ENGINEERING CONFERENCE, 10., Jaipur, 2017. Proceedings […] Jaipur, 2017.; Cahyo, 2021CAHYO, W. N. Finding novelty of research with Systematic Literature Mapping (SLM). Journal of Physics: Conference Series, v. 1764, n. 1, p. 012186, Feb. 2021.) presented in Figure 1:

  1. research motivation: the state of the art of Brazilian SHs was our research motivation. Literature analyses identified studies to understand and contextualise the topic from different perspectives and research fields. The diversity of field analysis enables an association of knowledge presented inResults and discussion item;

  2. research planning: the terms and search strings are presented in Figure 2. Boolean operators were included to define the relations between search terms and construct appropriate strings. Strings were applied to selected databases: Scopus, ScienceDirect, Web of Science, and Scielo, which combine a significant number of journals indexed with quality criteria. To improve the analysis of studies using the automatic criteria, a practical evaluation procedure was adopted to select or exclude papers through the StArt software, which classifies studies by score and number of citations. Moreover, our analysis strategy used inclusion and exclusion criteria by title and abstract reading. After the first inclusion and exclusion criteria by StArt software, all Brazilian SH studies were selected in Portuguese and English. Snowballing processes were applied to add studies to the sample. However, studies published in non-open access journals were excluded;

  3. research implementation: after selection, accepted studies were read, and the data extracted. The SMS method was applied. Studies were classified by main topic issues (Figure 3) and organised by categories. SLR method was applied for quality and data synthesis. The results of this analysis are presented in Results and discussion item; and

  4. analysis and synthesis: existing studies developed in Brazil were identified and contextualised. Description of SH issues - qualitative analysisitem presents the SH topic and sub-topic problems and guidelines to improve the problem raised, as well as an overview of the association of issues. Review outcomes were synthesised and presented as a result of the research. The relation of topics is presented (Figure 3).

Results and discussion

Quantitative analysis

The sample selection was developed in March 2022. Strings and sample analysis are presented in Figure 2. For the string, terms such as “social housing” and its variations, upgrading and its variations, MCMV, “social impacts”, and “social cost”, and Brazil to limit the search for the region were applied to compose strings. The search period was from the beginning of 2000 to March 2022. Moreover, 935 documents were identified in the first search. The first search identified 935 studies documents. After applying the SLR protocol, the study sample included 122 studies covering articles published between 2006 and 2021.

The research evaluated clusters of studies on SH. The analysis identified five topics outlined in SH studies:

  1. urban accessibility;

  2. use of resources;

  3. public policy and SH programmes;

  4. post-occupancy evaluation (POE); and

  5. Brazilian SH financing.

Figure 3 presents the topic and references of the studies considered in each topic.

Urban accessibility is widely investigated in geography and architectural studies. In sociology, topics such as public policies that support the production of SH, as well as the organisational structure of agents involved, are frequently addressed in investigations. In economics, the process and performance of the financial market in SH productions and the relationship between product quality, location of developments and the real estate market are investigated. In the construction area, including architecture and civil engineering, POEs and sustainability issues are found. User satisfaction, transformations and possibilities of SH improvements are the main investigated topics in POE studies.

The distribution of study topics over time shows that specific issues are more prevalent in certain years (Figure 4). Studies on urban accessibility and sustainability issues peaked in 2017. The topic of public policy decreased since 2015. Sustainability issues have appeared since 2010, with peaks in 2015 and 2017. Brazilian SH finances and POEs are less studied overall in relation to SH. Some POE studies were developed between 2015 to 2018.

We analysed studies by localisation to understand where Brazilian SH housing investigations are more prevalent. Figure 5 locates studies published by states and regions of Brazil.Furthermore, information on contracted units is presented (Figure 6).

The MCMV programme covers most of the Brazilian territory (Moreira; Silveira; Euclydes, 2017MOREIRA, V. S.; SILVEIRA, S. F. R.; EUCLYDES, F. M. “Minha Casa, Minha Vida” em números: quais conclusões podemos extrair? A Construção da Administração do Século XXI. In: ENCONTRO BRASILEIRO DE ADMINISTRAÇÃO E PÚBLICA, 4., João Pessoa, 2017. Anais [...] João Pessoa, 2017.). However, according to data from the electronic system of the Citizen Information Service (Serviço de Informação ao Cidadão - SIC3 3 The Citizen Information Service (SIC) is the unit responsible for answering requests for access to information made to the Ministry of Economy. https://www.gov.br/economia/pt-br/canais_atendimento/ouvidoria/sic ), the Northeast region has the largest number of residential contracted units (RUs), with the Southeast second largest (RUs).

The Southeast, which includes the state of São Paulo, has many studies. Studies are located in the cities of São Paulo, Campinas, São José dos Campos, Araraquara, Região do Grande, ABC (Santo André, São Bernardo do Campo, São Caetano do Sul, Diadema, Mauá, Ribeirão Pires e Rio Grande da Serra), São José do Rio Preto, São Francisco, Osasco, São Carlos.The State of Minas Gerais has specific studies for the cities of Viçosa, Ponte Nova, Visconde do Rio Branco, Ubá, Montes Claros, Belo Horizonte, Uberlândia and Ouro Preto). In contrast, the State of Rio de Janeiro has research on the cities of Rio de Janeiro, Várzea, Teresópolis, Serra da Tiririca, Niterói, and Petrópolis.

In the South, for the state of Rio Grande do Sul, research was developed in Porto Alegre, Santa Maria, São Leopoldo, Uruguaiana and in the state of Parana, there is research from Curitiba, Maringá and Londrina. In contrast, the state of Santa Catarina concentrates research on the cities of Florianópolis, Blumenau and Canoinhas.

The Northeast is the region with the largest number of contracted RUs. The state of Sergipe presents studies from Aracaju, Itabaiana, Lagarto, Estância and Nossa Senhora da Glória. In contrast, in the state of Bahia, the studies are mainly concentrated on the city of Salvador. In the state of Rio Grande do Norte, the cities found are Natal and Parnamirim, and in the state of Ceará, we find research on Nova Olinda and the city of Fortaleza. In the state of Pernambuco, the studies are concentrated in Recife. In Piauí, there are studies in Teresina.

In contrast, the north had more studies published than the northeast of Brazil, although fewer RUs were built. In the state of Pará, Parauapebas, Abaetetuba and Belém present studies, while in the state of Amazonas, the city of Manaus appears, as well as some small towns along the Amazon River. Finally, the Centre-west region represented by the states of Mato Grosso do Sul, Mato Grosso and Goias presents data from the cities of Campo Grande, Dourados and Goiânia.

Guidelines to overcome the negative impacts

SH programmes are widely studied in various research and knowledge fields. These studies demonstrate how a public policy focused on housing impacts society in social, economic and environmental contexts and how it affects the built environment. Thus, our theoretical background covers five topics. A review of urban accessibility, public policy and SH programmes, Brazilian SH financing, post-occupancy evaluation and use of resources issues are presented. Subtopics are also presented.

Urban accessibility

Three issues are discussed in urban accessibility: urban design, effective use of Special Social Interest Zones (Zonas Especiais de Interesse Social - ZEIS, in Portuguese), and urban infrastructure and equipment.

Urban design

Although urban design has social implications, many Brazilian SH projects are fragmented, characterised by socio-spatial segregation and by high concentrations of low-income people (Medrano; Spinelli, 2014MEDRANO, L.; SPINELLI, J. Urban policies and projects for social housing in central area: the case of the Habitasampa competition (São Paulo, Brazil). Habitat International , v. 42, p. 39-47, 2014.; Carvalho; Medeiros, 2017CARVALHO, A. de A. V. de; MEDEIROS, V. A. S. de. O papel do programa Minha casa, minha vida no processo de construção das cidades: a perspectiva configuracional. Urbe.

Social Housing and the Minha Casa Minha Vida Program - range 1: Environmental issue in housing production. Urbe , v. 12, p. e20190312, p. 1-15, 2020. ). Even SH systems that provide well-inserted housings fail in this respect (Silva; Fleury e Silva, 2013SILVA, R.; FLEURY e SILVA, B. O Programa Habitacional Minha Casa Minha Vida: uma avaliação através do caso do Conjunto Albino Meneguetti em Maringá-PR. Cuadernos de Vivienda y Urbanismo , p. 1-11, 2013.; Moura, 2014MOURA, J. M.

A face do tecido urbano e as mazelas ao acesso à moradia social: como o caso do município de petrópolis desvenda a construção de uma lenda urbana. Geo UERJ , v. 31, p. 219-248, 2017.). Most SH projects of Faixa 1 and Faixa 1,5 are located in monofunctional neighbourhoods (Leitão; Araújo, 2013LEITÃO, G.; ARAUJO, H. Quando o futuro repete o passado: uma análise dos conjuntos habitacionais produzidos pelo programa minha casa/ minha vida na cidade do Rio de Janeiro. Cuadernos de Vivienda y Urbanismo, p. 1-12, jul. 2013. ; Mioto, 2013MIOTO, B.

Revista de Direito da Cidade , v. 8, n. 3, p. 859-885, 2016.).

Real estate speculation also exerts pressures on urban morphologies favouring the finance of new homes for middle-class families well inserted in urban areas and expelling SH to the periphery of urban areas (Garcia; Fernandes, 2015GARCIA, D. V.; FERNANDES, Q. E. An overview of rural areas in Brazil and urban land changes due to the “Minha Casa Minha Vida” affordable housing programme. In: WORLD CONGRESS OF THE INTERNATIONAL FEDERATION OF LANDSCAPE ARCHITECTS,52.,St. Petersburg, 2015. Proceedings […] St. Petersburg, 2015.; Sousa; Braga, 2020SOUSA, I. C. N. de; BRAGA, R. Social Housing and the Minha Casa Minha Vida Program - range 1: Environmental issue in housing production. Urbe , v. 12, p. e20190312, p. 1-15, 2020. ). The repetitive SH production model has led to a recurrent negative social impact for both residents of these dwellings and society as a whole (Muianga et al., 2021MUIANGA, E. A. D. et al. Critical analysis of housing condition impacts on residents’ well-being and social costs. Gestão & Tecnologia de Projetos , v. 16, n. 4, p. 33-66, out. 2021.).

Special Social Interest Zones- ZEIS

ZEIS are demarcated areas in a municipal master plan (Plano Diretor Municipal) within a city's territory for housing settlements for low-income populations. However, ZEIS are ineffective in relation to the social function they were intended for (França, 2015FRANÇA, K. C. B. Os gargalos para a provisão habitacional em municípios de pequeno porte: análise do programa Minha Casa, Minha Vida. Urbe , v. 7, n. 3, p. 325-339, 2015.; Mastrodi; Zaccara, 2016ZACCARA, S. M. L.; MASTRODI, J. O que é o objeto “moradia” do Programa Minha Casa, Minha Vida? Revista de Direito da Cidade , v. 8, n. 3, p. 859-885, 2016.; Acolin; Green, 2017ACOLIN, A.; GREEN, R. K. Measuring housing affordability in São Paulo metropolitan region: incorporating location. Cities, v. 62, p. 41-49, 2017.). Land values and, therefore, the final value of a housing unit is decisive in the marginalisation of SH beneficiaries, mainly the lowest-income group (Campos, 2018CAMPOS, B. F. O ímpeto privado na definição da socioespacialidade urbana: as habitações sociais de mercado e de interesse social em Dourados/MS (2007-2013). PEGADA - A Revista da Geografia do Trabalho, v. 19, n. 1, p. 182-203, jun. 2018.; Cunha; Silva, 2018CUNHA, T. A. da; SILVA, M. S. da. Evidências de imprecisão nas políticas habitacionais brasileiras: o caso de São Paulo. Urbe. Revista Brasileira de Gestão Urbana , v. 10, n. 1, p. 52-71, 2018.). Consequently, residents must spend a long time commuting daily to access jobs, education institutions, and services for daily activities (França, 2015FRANÇA, K. C. B. Os gargalos para a provisão habitacional em municípios de pequeno porte: análise do programa Minha Casa, Minha Vida. Urbe , v. 7, n. 3, p. 325-339, 2015.).

Living in SH estates, low-income families also face costs not previously foreseen. Residents have new expenses, such as utility bills and the instalments of their new home (Muianga et al., 2021MUIANGA, E. A. D. et al. Critical analysis of housing condition impacts on residents’ well-being and social costs. Gestão & Tecnologia de Projetos , v. 16, n. 4, p. 33-66, out. 2021.). The financial condition of such families does not enable them to assume new property expenditures which impact their cost of living. The difficulty of affordability due to low income, in some cases, forces SH residents to return to their original places, often not legalised lands, which are generally more connected to urban areas, however, more vulnerable (Baltrusis; Mourad, 2014MOURA, J. M. O programa Minha Casa, Minha Vida na região metropolitana de Natal: uma análise espacial dos padrões de segregação e desterritorialização. Urbe . Revista Brasileira de Gestão Urbana , v. 6, n. 3, p. 339-359, 2014.).

Urban infrastructure and equipment

The impact of territorial segregation on intra-urban dynamics generates neighbourhoods that demand public infrastructure, public and private services and equipment, access to sewage systems, public transport, public spaces, green areas, leisure and cultural activities (Leitão; Araujo, 2013LEITÃO, G.; ARAUJO, H. Quando o futuro repete o passado: uma análise dos conjuntos habitacionais produzidos pelo programa minha casa/ minha vida na cidade do Rio de Janeiro. Cuadernos de Vivienda y Urbanismo, p. 1-12, jul. 2013. ; Lima et al., 2015LIMA, J. J. F. et al.

E a Cidade? Avaliação do Programa Minha Casa Minha Vida em seis estados brasileiros . Rio de Janeiro: Letra Capital , 2015.;Menezes, 2016MENEZES, V. M. O. de. Arranjos familiares de beneficiários do Programa Minha Casa Minha Vida: trajetórias de benefício e percepções de bem-estar social. Cadernos Metrópole, v. 18, n. 35, p. 257-282, 2016.; Meireles; Castro, 2017MEIRELES, E.; CASTRO, C. M. P. de. Provisão do Programa Minha Casa, Minha Vida em São José do Rio Preto, SP: inserção urbana e adequação socioeconômica e ambiental - um estudo de caso do conjunto habitacional Nova Esperança. Ambiente Construído , Porto Alegre, v. 17, n. 3, p. 219-233, jul./set. 2017.; Prudente; Leiro, 2017PRUDENTE, A. A.; LEIRO, M. S. DE. Inserção Urbana no Programa Minha Casa Minha Vida (MCMV): avaliação do conjunto habitacional Coração de Maria no MUNICÍPIO de Salvador, Bahia, Brasil. Hábitat y Sociedad, v. 10, p. 269-288, 2017.). Moreover, the necessity of private cars, daily dislocations demand private costs and may cause health impacts due to air pollution and stress, and cause productivity losses (Mioto, 2013MIOTO, B. O programa “minha casa, minha vida” e a segregação sócio-espacial: a atuação do capital incorporador e do estado na construção do urbano Brasileiro. Cuadernos de Vivienda y Urbanismo , p. 1-11, jul. 2013.; Borges; Barreira; Costa, 2017BORGES, E. D. M.; BARREIRA, C. C. M.; COSTA, E. P. V. da S. M. da. Habitação social e desenvolvimento urbano sustentável: o caso da região metropolitana de Goiânia. Geo UERJ, v. 30, p. 122-144, 2017.; Souza; Sugai, 2018SOUZA, E. L.; SUGAI, M. I. Minha Casa Minha Vida: periferização, segregação e mobilidade intraurbana na área conurbada de Florianópolis. Cadernos Metrópole , v. 20, n. 41, p. 75-98, 2018.). Therefore, poorly inserted housing may trigger social impacts and costs (Muianga et al., 2021MUIANGA, E. A. D. et al. Critical analysis of housing condition impacts on residents’ well-being and social costs. Gestão & Tecnologia de Projetos , v. 16, n. 4, p. 33-66, out. 2021.).

In some cases, to overcome such main failures and impacts, in critical situations of urban fragmentation, local communities attempt to develop their own services that operate independently from the overall logic of an urban system (Hehl, 2016HEHL, R. Cultivating the field in the global hinterland: community building for mass housing in the Amazon region. Architectural Design , v. 86, n. 4, p. 34-41, 2016.). Although local services are seen as potential extra income for families, they may cause irregular occupation of public land and illegal and uncontrolled economic activities (Leitão; Araujo, 2013LEITÃO, G.; ARAUJO, H. Quando o futuro repete o passado: uma análise dos conjuntos habitacionais produzidos pelo programa minha casa/ minha vida na cidade do Rio de Janeiro. Cuadernos de Vivienda y Urbanismo, p. 1-12, jul. 2013. ).

Guidelines to overcome the negative impacts regarding urban accessibility

SH programmes, therefore, should be restructured to include urban accessibility, promoting adequate locations for SH projects with appropriate infrastructure (Medrano; Spinelli, 2014MEDRANO, L.; SPINELLI, J. Urban policies and projects for social housing in central area: the case of the Habitasampa competition (São Paulo, Brazil). Habitat International , v. 42, p. 39-47, 2014.; Garcia; Fernandes, 2015GARCIA, D. V.; FERNANDES, Q. E. An overview of rural areas in Brazil and urban land changes due to the “Minha Casa Minha Vida” affordable housing programme. In: WORLD CONGRESS OF THE INTERNATIONAL FEDERATION OF LANDSCAPE ARCHITECTS,52.,St. Petersburg, 2015. Proceedings […] St. Petersburg, 2015.; Mastrodi; Zaccara, 2016ZACCARA, S. M. L.; MASTRODI, J. O que é o objeto “moradia” do Programa Minha Casa, Minha Vida? Revista de Direito da Cidade , v. 8, n. 3, p. 859-885, 2016.; Cunha; Silva, 2018CUNHA, T. A. da; SILVA, M. S. da. Evidências de imprecisão nas políticas habitacionais brasileiras: o caso de São Paulo. Urbe. Revista Brasileira de Gestão Urbana , v. 10, n. 1, p. 52-71, 2018.). Thus, it is important to reduce real estate “businesses” in SH production (Pequeno; Elias, 2011PEQUENO, R.; ELIAS, D. Estruturação Urbana E Desigualdades Socioespaciais. Revista Geográfica de América Central, v. 2, n. 1995, p. 1-18, 2011.; Rizek; Amore; Camargo, 2014RIZEK, C. S.; AMORE, C. S.; CAMARGO, C. M. de. Política social, gestão e negócio na produção das cidades: o programa minha casa minha vida “entidades”. Caderno CRH , v. 27, n. 72, p. 531-546, 2014.). Therefore, it is necessary to increase the institutional and regulatory capacity of SH programmes to reduce location impacts (Pequeno; Elias, 2011PEQUENO, R.; ELIAS, D. Estruturação Urbana E Desigualdades Socioespaciais. Revista Geográfica de América Central, v. 2, n. 1995, p. 1-18, 2011.; Santos; Matos, 2017SANTOS, A. M. S. P.; MATOS, C. O Mito da escassez fundiária e o acesso à moradia social:o caso do município de Petrópolis. Geo UERJ , v. 31, p. 648-668, 2017.; Jesus; Denaldi, 2018JESUS, P.; DENALDI, R. Experiências de regulação urbana e suas possibilidades: Análise a partir do programa minha casa minha vida na região do grande ABC (São Paulo). Eure, v. 44, n. 132, p. 67-87, 2018.). Moreover, it is important to improve the use of ZEIS for low-income housing, reducing the pressure for precarious occupations in environmentally fragile areas (Acolin; Green, 2017ACOLIN, A.; GREEN, R. K. Measuring housing affordability in São Paulo metropolitan region: incorporating location. Cities, v. 62, p. 41-49, 2017.; Campos, 2018CAMPOS, B. F. O ímpeto privado na definição da socioespacialidade urbana: as habitações sociais de mercado e de interesse social em Dourados/MS (2007-2013). PEGADA - A Revista da Geografia do Trabalho, v. 19, n. 1, p. 182-203, jun. 2018.; Sousa; Braga, 2020SOUSA, I. C. N. de; BRAGA, R. Social Housing and the Minha Casa Minha Vida Program - range 1: Environmental issue in housing production. Urbe , v. 12, p. e20190312, p. 1-15, 2020. ). Municipal actions should provide infrastructure and equipment and public transport lines based on social demands for work, health, education, leisure and cultural services (Kopper, 2017KOPPER, M. House-ing urban kin family configurations, household economies and inequality in brazil’s public housing. Articulo - Revue de Sciences Humaines, v. 20, n. 20, 2017.; Moreira; Silveira; Euclydes, 2018SILVEIRA, S. R. et al.

Confins, Revista Franco-Brasilera de Geografia, n. 41, 2019.).

Understanding SH beneficiary’s needs and desires through participatory process is important to define the integration of SH neighbourhoods and urban spaces (Sobrinha et al., 2015SOBRINHA, M. D. P. B. et al. Minha Casa, Minha Vida na Região Metropolitana de Natal: inserção urbana, qualidade do projeto e seus efeitos na segregação socioespacial. Em: AMORE, C. S.; SHIMBO, L. Z.; RUFINO, M. B. C.

N.; KANASHIRO, M. Análise do comércio e dos serviços nos empreendimentos do Programa Minha Casa, Minha Vida (PMCMV): estudo de caso do Residencial Vista Bela - Londrina, PR.

Arquiteturarevista, v. 13, n. 1, p. 1-8, jan. 2017.). The involvement of communities through participatory planning is recommended to develop legitimate urban and SH planning with local interests (Silva; Fleury e Silva, 2013SILVA, R.; FLEURY e SILVA, B.

Public policy and SH programme

Three issues are discussed in relation to public policies and SH programmes: the housing deficit, the National Rural Housing Program and mass reproduction.

Housing deficit

SH programmes are launched to reduce housing deficits and increase the beneficiaries' quality of life. This goal has, however, yet to be met. A diversity of negative impacts still represents an obstacle to SH policies (Cardoso; Mello; Jaenisch, 2015CARDOSO, A. L.; MELLO, I. de Q. E.; JAENISCH, S. T. A implementação do Programa Minha Casa Minha Vida na Região Metropolitana do Rio de Janeiro: agentes, processos e contradições. Em: AMORE, C. S.; SHIMBO, L. Z.; RUFINO, M. B. C. (ed.). Minha Casa... E a Cidade? Avaliação do Programa Minha Casa Minha Vida em seis estados brasileiros . Rio de Janeiro: Letra Capital , 2015.; Monteiro, 2015MONTEIRO, F. A. A habitação social na atualidade na Região Metropolitana de Curitiba/Pr. Geo UERJ , v. 27, p. 156-175, 2015.; Ferreira et al., 2019FERREIRA, G. G. et al. Housing policy in Brazil: an advocacy coalition analysis of the national social interest housing system versus minha casa, minha vida program. Urbe , v. 11, p. e20180012, 2019.). The MCMV program was fundamental in helping to remove people living in risk areas. However, this contributed to an increase in socio-spatial segregation having a negative effect on families’ quality of life (Cardoso; Mello; Jaenisch, 2015CARDOSO, A. L.; MELLO, I. de Q. E.; JAENISCH, S. T. A implementação do Programa Minha Casa Minha Vida na Região Metropolitana do Rio de Janeiro: agentes, processos e contradições. Em: AMORE, C. S.; SHIMBO, L. Z.; RUFINO, M. B. C. (ed.). Minha Casa... E a Cidade? Avaliação do Programa Minha Casa Minha Vida em seis estados brasileiros . Rio de Janeiro: Letra Capital , 2015.; Ferreira et al., 2019FERREIRA, G. G. et al. Housing policy in Brazil: an advocacy coalition analysis of the national social interest housing system versus minha casa, minha vida program. Urbe , v. 11, p. e20180012, 2019.). The housing deficit involves issues related to both quality and quantity, and the maximised production of new units in deprived places does not solve SH impacts ( Zaccara; Mastrodi, 2016ZACCARA, S. M. L.; MASTRODI, J. O que é o objeto “moradia” do Programa Minha Casa, Minha Vida? Revista de Direito da Cidade , v. 8, n. 3, p. 859-885, 2016.).

SH programmes facilitate decision-making and outsourcing to private developers, which leads, in many cases, to reduced SH quality located on low-cost land (Thery, 2017THERY, H. Novas paisagens urbanas do Programa Minha Casa, Minha Vida. Mercartor, v. 16, p. 1-14, 2017.; Albert, 2021ALBERT, V. A. Mobilising the periphery: Brazil’s My House My Life Programme and the homeless workers’ movement. Bulletin of Latin American Research, v. 40, n. 1, p. 84-99, Jan. 2021.). These programmes are mostly aligned with profit generation for its agents, especially developers, builders and banks, which have a low alignment with public political goals (Zaccara; Mastrodi, 2016ZACCARA, S. M. L.; MASTRODI, J. O que é o objeto “moradia” do Programa Minha Casa, Minha Vida? Revista de Direito da Cidade , v. 8, n. 3, p. 859-885, 2016.). Moreover, the program also tends to reinforce the intense real estate appreciation seen in Brazilian metropolitan areas, further increasing the difficulties of access to housing through rent and other forms of production, thus imposing new inequalities (Rufino et al., 2015RUFINO, M. B. C. et al. A produção do Programa PMCMV na Baixada Santista: habitação de interesse social ou negócio imobiliário? Em: AMORE, C. S.; SHIMBO, L. Z.; RUFINO, M. B. C. (ed.). Minha Casa... E a Cidade? Avaliação do Programa Minha Casa Minha Vida em seis estados brasileiros . Rio de Janeiro: Letra Capita, 2015. ). It is also evident that Brazilian SH is guided by short-term business and economic logic and is not part of an effective structural policy of planning and urban reform of long-term processes, which is essential to improve the quality of life (Loureiro; Macário; Guerra, 2015LOUREIRO, M. R.; MACÁRIO, V.; GUERRA, P. H. Legitimidade e efetividade em arranjos institucionais de políticas públicas: O programa minha casa minha vida. Revista de Administração Pública, v. 49, n. 6, p. 1531-1554, 2015.; Eskes; Vieira, 2016ESKES, N.; VIEIRA, A. Rethinking Minha Casa, Minha Vida: the resurgence of public space. Architectural Design, v. 86, n. 3, p. 54-59, 2016.).

National rural housing program

The National Rural Housing Program (Programa Nacional de Habitação Rural in Portuguese - PNHR), the rural extension of the MCMV, provides housing access for people in rural areas to maintain their activities in place (Costa; Silva; Santos, 2018COSTA, M. de L. P. M.; SILVA, M. H. da; SANTOS, T. R. B. dos. Os caminhos da dispersão urbana no bairro de Campo Grande - cidade do Rio de Janeiro. Geograficidade, v. 8, n. 1, p. 95-107, 2018.; Costa et al., 2019COSTA, M. F. B. F. et al. Rural housing and sustainable regional development: the national rural housing program in Nova Olinda/Ce. Fronteiras, v. 8, n. 3, p. 379-396, 2019.). It is designed to minimise the national housing deficit, allowing people to build a new house or even renovate the house they already own (Rangel et al., 2020RANGEL, J. A. et al. Minha casa minha vida program and its repercussion on a regional scale: a study about the amazon river delta. Revista Brasileira de Gestão e Desenvolvimento Regional, v. 16, n. 1, p. 32-44, 2020.). At the same time, PNHR demonstrates an intention to avoid the creation of peripheries in spaces that are considered rural (Rangel et al., 2020RANGEL, J. A. et al. Minha casa minha vida program and its repercussion on a regional scale: a study about the amazon river delta. Revista Brasileira de Gestão e Desenvolvimento Regional, v. 16, n. 1, p. 32-44, 2020.). The PNHR, although predominantly rural, often demands urbanised land and fails to provide sufficient infrastructure (water, energy, sewage, drainage), quality public transport networks, and in addition, adequate access to education, health and supply facilities (Buonfiglio, 2018BUONFIGLIO, L. V. Housing of social interest. Mercator, v. 17, n. 2, p. 1-16, 2018.; Rangel et al., 2020RANGEL, J. A. et al. Minha casa minha vida program and its repercussion on a regional scale: a study about the amazon river delta. Revista Brasileira de Gestão e Desenvolvimento Regional, v. 16, n. 1, p. 32-44, 2020.).

Urban dispersion is also seen near PNHR neighbourhoods, with growing real estate launches, on cheaper land, reaching areas farther from urban centres. Although the urban mesh attracts the deployment of mixed-use buildings, the legislation is inadequate and cannot control occupations in rural areas (Costa; Silva; Santos, 2018COSTA, M. de L. P. M.; SILVA, M. H. da; SANTOS, T. R. B. dos. Os caminhos da dispersão urbana no bairro de Campo Grande - cidade do Rio de Janeiro. Geograficidade, v. 8, n. 1, p. 95-107, 2018.).

Mass reproduction

Even though MCMV has improved living conditions for vulnerable families, this programme still intensifies stigmatisation (Vannuchi et al., 2015VANNUCHI, L. et al. Inserção urbana no MCMV e a efetivação do direito à moradia adequada: uma avaliação de sete empreendimentos no estado de São Paulo. Rio de Janeiro: Carta Capital, 2015. ). Despite dwellers demonstrating satisfaction by owning a property, which may be considered a positive social impact (Quirino et al., 2015QUIRINO, B. S. et al. Analysis of the housing program “Minha Casa, Minha Vida” on the perspective of social innovation and evolution of public policy. Revista de Gestão Social e Ambiental, v. 9, n. 3, p. 97-117, 2015.), they are still restricted concerning experiencing the city in its diversity (Vannuchi et al., 2015; Serapião, 2016SERAPIÃO, F. Linking the formal and informal: favela urbanisation and social housing in São Paulo. Architectural Design , v. 86, n. 3, p. 70-79, 2016.). Health, education, work, leisure, culture, sociability, and other amenities are essential for long-term satisfaction (Menezes; Mourão, 2017MENEZES, G.; MOURÃO, L. Programa Minha Casa Minha Vida sob a perspectiva da qualidade de vida. Psicoperspectivas, v. 16, n. 3, p. 149-163, 2017.). However, as a major promoter of SH programmes, the lack of governmental decisions and leadership transfers critical decisions, such as design, land occupation, and production process, to outsourcing (SERAPIÃO, 2016SERAPIÃO, F. Linking the formal and informal: favela urbanisation and social housing in São Paulo. Architectural Design , v. 86, n. 3, p. 70-79, 2016.).

In general, mass reproduction of the same housing model entailed a series of cultural, economic and management problems as regional and cultural diversity in large-scale development is reduced (Vannuchi et al., 2015VANNUCHI, L. et al. Inserção urbana no MCMV e a efetivação do direito à moradia adequada: uma avaliação de sete empreendimentos no estado de São Paulo. Rio de Janeiro: Carta Capital, 2015. ). The literature points to several actions and measures to reduce SH production errors. However, incorporating these actions into a practical process is still scarce (Muianga et al., 2022MUIANGA, E. A. D. et al. Housing transformations and their impacts on the well-being of dwellers. Ambiente Construído , Porto Alegre, v. 22, n. 4, p. 255-274, out./dez. 2022.).

Guidelines to overcome the negative impacts regarding public policies and SH programme

There is a societal value in owning a home or living in a well-located and built housing estate. SH programmes should therefore put less emphasis on the cost of production, focusing on the positive impacts on the lives of individuals that social housing programmes should have (Menezes; Mourão, 2017MENEZES, G.; MOURÃO, L. Programa Minha Casa Minha Vida sob a perspectiva da qualidade de vida. Psicoperspectivas, v. 16, n. 3, p. 149-163, 2017.).Furthermore, SH programmes should avoid the repetition of failures and establish a continuous improvement process (Finger; González; Kern, 2015FINGER, F. B.; GONZÁLEZ, M. S.; KERN, A. P. Control of finished work: final quality inspection in a social housing project. Revista Ingenieria de Construccion, v. 30, n. 2, p. 147-153, 2015.). The local administrative capacities associated with the preference of dwellers and decentralised public policies are necessary. Historical evaluations of SH should also contribute to improvements in policies, programmes and projects (Lavalle; Rodrigues; Guicheney, 2019LAVALLE, A. G.; RODRIGUES, M.; GUICHENEY, H. Local agency and federal inducement: the workings of the municipal housing policy in Recife and Curitiba. Revista de Sociologia e Politica, v. 27, n. 71, p. 1-27, 2019.).

Refurbishment and upgrading actions with participatory processes are also important for improving SH programmes. Self-management (autogestão in Portuguese) has been advocated to increase citizen participation in housing production (Stiphany; Ward, 2019STIPHANY, K. M.; WARD, P. M. Autogestão in an era of mass social housing: the case of Brazil’s Minha Casa Minha Vida-Entidades Programme. International Journal of Housing Policy, v. 19, n. 3, p. 311-336, 2019.), acting as a procedure for the democratisation of design (Camargo, 2020CAMARGO, C. M. de. Minha Casa Minha Vida - Entities: new arrangements for the operations of Brazilian housing policy. Revista Brasileira de Ciências Sociais, v. 35, n. 102, e3510219, 2020. ). This may increase the opportunity for housing policies to integrate the formal and informal city by linking the most precarious areas with consolidated urbanisation (Serapião, 2016SERAPIÃO, F. Linking the formal and informal: favela urbanisation and social housing in São Paulo. Architectural Design , v. 86, n. 3, p. 70-79, 2016.). There is a need to encourage stakeholders (construction companies, financial institutions, agencies and public policies, and beneficiaries) involved in SH programmes to look for alternatives that may reduce these projects' recurring negative social impacts. Thus, upgrading SH is not only about technical issues but may touch on subjective details to advance long-term, sustainability-oriented solutions and social change.

Brazilian SH financing

Two issues are discussed in relation to Brazilian SH finance: the real estate market and delinquent contracts.

Real estate market

Although MCMV has made significant progress in providing housing for low-income people (Falchetti, 2020FALCHETTI, C. Social policy and the dynamics of neoliberalism: the My House, My life program and the commodified mediation of housing. Latin American Perspectives, v. 47, n. 2, p. 131-146, 2020.), SH programmes tend to transfer the main decision-making to the real estate market (builders, developers, and agencies). SH is mobilised as an instrument to include low-income households as consumers in the real estate market (Conceição; Mastrodi, 2016MASTRODI, J.; ZACCARA, S. M. L. Sobre a promoção do direito à moradia e do direito à cidade: um estudo à luz da política urbana do município de Campinas. Revista de Direito da Cidade , v. 8, n. 1, p. 1-28, 2016., Kopper, 2016KOPPER, M. “Minha Casa, Minha Vida”: experts, sentidos de classe e a invenção do “mercado” da casa própria no Brasil contemporâneo. Horizontes Antropológicos, v. 22, n. 45, p. 185-215, 2016.; Falchetti, 2020FALCHETTI, C. Social policy and the dynamics of neoliberalism: the My House, My life program and the commodified mediation of housing. Latin American Perspectives, v. 47, n. 2, p. 131-146, 2020.; Santoro; Chiavone, 2020SANTORO, P. F.; CHIAVONE, J. de A. Negócios de impacto e habitação social: uma nova fronteira do capital financeirizado? Cadernos Metrópole , v. 22, n. 49, p. 683-704, 2020.).

Even knowing that SH programmes should be aligned with the interests of social policies (Outeiro; Nascimento, 2020OUTEIRO, G. M.; NASCIMENTO, D. M. A trajetória da política habitacional a partir da perspectiva do institucionalismo histórico. Revista de Direito da Cidade , v. 12, n. 2, p. 1160-1183, 2020.), the real estate market is highly autonomous in project development and execution, and therefore demonstrates less consideration towards social outcomes (Campos; Guilhoto, 2017CAMPOS, R. B. A.; GUILHOTO, J. J. M. The socioeconomic impact of low-income housing programs: An interregional input-output model for the state of Sao Paulo and the rest of Brazil. Habitat International , v. 65, n. Suppl. C, p. 59-69, jul. 2017. ; Alvarenga; Reschilian, 2018ALVARENGA, D. D. N.; RESCHILIAN, P. R. Financeirização da moradia e segregação socioespacial: Minha Casa, Minha Vida em São José dos Campos, Taubaté e Jacareí/SP. Urbe. Revista Brasileira de Gestão Urbana, v. 10, n. 3, p. 473-484, 2018.; Outeiro; Nascimento, 2020OUTEIRO, G. M.; NASCIMENTO, D. M. A trajetória da política habitacional a partir da perspectiva do institucionalismo histórico. Revista de Direito da Cidade , v. 12, n. 2, p. 1160-1183, 2020.). In the current context, the main decisions are taken by economic agents who are more interested in profit than in social benefits, to the detriment of the population that does not participate in the process as an agent (Outeiro; Nascimento, 2020OUTEIRO, G. M.; NASCIMENTO, D. M. A trajetória da política habitacional a partir da perspectiva do institucionalismo histórico. Revista de Direito da Cidade , v. 12, n. 2, p. 1160-1183, 2020.).

Even with rules and restrictions, SH is developed in a contiguous model. For instance, an official limitation of housing units per project is stipulated to 500 (five hundred) for single-family units and 250 (two hundred and fifty) for multi-family units or apartments (Caixa, 2021CAIXA. Minha Casa Minha Vida - Habitação Urbana. Available: https://www.caixa.gov.br/voce/habitacao/minha-casa-minha-vida/urbana/Paginas/default.aspx. Access: 27 ago. 2021.
https://www.caixa.gov.br/voce/habitacao/...
). However, several projects, known as “contiguous developments”, are developed beyond the official housing unit’s limitation, known as “contiguous developments” which spatially configure significantly higher than 500 units (Nascimento et al., 2015NASCIMENTO, D. M. et al. Programa Minha Casa Minha Vida: desafios e avanços na Região Metropolitana de Belo Horizonte. In: AMORE, C. S.; SHIMBO, L. Z.; RUFINO, M. B. C. (ed.). Minha Casa... E a Cidade? Avaliação do Programa Minha Casa Minha Vida em seis estados brasileiros . Rio de Janeiro: Letra Capital , 2015. ; Santoro; Chiavone, 2020SANTORO, P. F.; CHIAVONE, J. de A. Negócios de impacto e habitação social: uma nova fronteira do capital financeirizado? Cadernos Metrópole , v. 22, n. 49, p. 683-704, 2020.). The social costs of living in such large developments are still neglected (Ferreira, 2012FERREIRA, J. S. W. Produzir casas ou construir cidades? Desafios para um novo Brasil Urbano Parâmetros de qualidade para a implementação de projetos habitacionais e urbanos. Gestão & Tecnologia de Projetos, v. 8, n. 2, 2012. ; Silva; Alves, 2014SILVA, C. F.; ALVES, T. W. Dinâmica dos financiamentos habitacionais nos municípios do Rio Grande do Sul de 2006 a 2010: Uma avaliação do Programa “Minha Casa, Minha Vida”. Revista de Administração Pública , v. 48, n. 1, p. 27-54, 2014.; Muianga et al., 2021MUIANGA, E. A. D. et al. Critical analysis of housing condition impacts on residents’ well-being and social costs. Gestão & Tecnologia de Projetos , v. 16, n. 4, p. 33-66, out. 2021.).

Thus, the main decisions of SH production are aligned with profit rather than social benefits, to the detriment of beneficiaries (Outeiro; Nascimento, 2020OUTEIRO, G. M.; NASCIMENTO, D. M. A trajetória da política habitacional a partir da perspectiva do institucionalismo histórico. Revista de Direito da Cidade , v. 12, n. 2, p. 1160-1183, 2020.). The reproduction of projects limits the creative capacity and restricts developer teams and architecture firms to work in a flexible, autonomous process to streamline the project design (Kopper, 2016KOPPER, M. “Minha Casa, Minha Vida”: experts, sentidos de classe e a invenção do “mercado” da casa própria no Brasil contemporâneo. Horizontes Antropológicos, v. 22, n. 45, p. 185-215, 2016.). Financial agents also have low actions for the social benefits of SH productions (Santoro; Chiavone, 2020SANTORO, P. F.; CHIAVONE, J. de A. Negócios de impacto e habitação social: uma nova fronteira do capital financeirizado? Cadernos Metrópole , v. 22, n. 49, p. 683-704, 2020.).

Defaulting contracts

Low income or the absence of income is one of the main criteria for selecting MCMV beneficiaries, which means that loans have not been subjected to credit risk analyses, thus leading to the programme having a high number of defaulting contracts (Vieira et al., 2019VIEIRA, J. R. de C. et al. Machine learning models for credit analysis improvements: predicting low-income families’ default. Applied Soft Computing Journal, v. 83, n. 105640, out. 2019.). Low effective income plays a significant role in the differential defaulting rates between cities and peripheral locations (Vieira et al., 2019VIEIRA, J. R. de C. et al. Machine learning models for credit analysis improvements: predicting low-income families’ default. Applied Soft Computing Journal, v. 83, n. 105640, out. 2019.). The combination of low incomes with peripheral locations may produce an unsolvable equation as job access and poor urban infrastructure tend to impose high costs on poor households, triggering higher defaulting rates and worse social outcomes (Klink; Denaldi, 2014KLINK, J.; DENALDI, R. On financialization and state spatial fixes in Brazil: a geographical and historical interpretation of the housing program My House My Life. Habitat International , v. 44, p. 220-226, 2014.; Acolin; Hoek-Smit; Eloy, 2019ACOLIN, A.; HOEK-SMIT, M. C.; ELOY, C. M. High delinquency rates in Brazil’s Minha Casa Minha Vida housing program: Possible causes and necessary reforms. Habitat International, v. 83, p. 99-110, 2019.).

Guideline to overcome the negative impacts regarding Brazilian SH financing

There is a need to develop effective and targeted actions to minimise the problem of defaulting in the MCMV programme and reduce real estate market pressures (Falchetti, 2020FALCHETTI, C. Social policy and the dynamics of neoliberalism: the My House, My life program and the commodified mediation of housing. Latin American Perspectives, v. 47, n. 2, p. 131-146, 2020.). A public guarantee fund may eliminate the risk of loan defaults during the construction period, while thereafter, units may be sold to the national housing bank that assumes subsequent risks (Klink; Denaldi, 2014KLINK, J.; DENALDI, R. On financialization and state spatial fixes in Brazil: a geographical and historical interpretation of the housing program My House My Life. Habitat International , v. 44, p. 220-226, 2014.; Fraga; Vieira, 2019VIEIRA, J. R. de C. et al. Machine learning models for credit analysis improvements: predicting low-income families’ default. Applied Soft Computing Journal, v. 83, n. 105640, out. 2019.). The workplace situation is a factor that leads families with lower income to constantly change residence, as they need to move where jobs can be found (Chaves, 2019CHAVES, C. A. B. M. The selling and renting of houses on the program “Minha Casa Minha Vida” in Parnamirim/RN. Urbe, v. 11, p. e20180033, p. 1-14, 2019.). Thus, job and income should also be addressed. Actions to map the professions of SH beneficiaries and provide services and employment systems are essential (Lima et al., 2009LIMA, L. P. et al. Perceived value in social housing projects. In: ANNUAL CONFERENCE OF THE INTERNATIONAL GROUP FOR LEAN CONSTRUCTION, 17., Taipei, 2009. Proceedings […] Taipei, 2009.; Fraga; Vieira, 2019VIEIRA, J. R. de C. et al. Machine learning models for credit analysis improvements: predicting low-income families’ default. Applied Soft Computing Journal, v. 83, n. 105640, out. 2019.). Providing actions to guarantee income through employment for SH beneficiary families is fundamental for investments and the continuity of the SH programmes.

Post Occupancy Evaluation (POE)

Two issues are discussed in relation to POE: transformation, cost of living and social participation.

Housing transformation

Because of all the adverse impacts of SH experienced by residents regarding poor quality neighborhoods and the design and construction of housing units, they act independently, adapting their homes, thus transforming and improving their physical environment (Villa et al., 2017VILLA, S. B. et al. Co-production and resilience in a Brazilian social housing: the case of shopping park neighbourhood. In: PLEA INTERNATIONAL CONFERENCE: DESIGN TO THRIVE, 33., Edinburgh, 2017. Proceedings […] Edinburgh, 2017.). Transformations occur mainly with the purpose of amplifying functional space, modifying the layout, providing new rooms for diverse activities, and meeting dwellers' needs (Kowaltowski et al., 2006KOWALTOWSKI, D. C. C. K. et al. Quality of life and sustainability issues as seen by the population of low-income housing in the region of Campinas, Brazil. Habitat International , v. 30, n. 4, p. 1100-1114, 2006., 2021KOWALTOWSKI, D. C. C. K. et al. Housing transformation in search of well-being. In: ENCONTRO NACIONAL DE CONFORTO NO AMBIENTE CONSTRUÍDO, 16.; ENCONTRO LATINO-AMERICANO DE CONFORTO NO AMBIENTE CONSTRUÍDO, 12., Palmas, 2021. Anais [...] Palmas, 2021.; Berr et al., 2015BERR, L. R. et al. Indicador de falhas de qualidade baseado na percepção dos usuários de Habitação de Interesse Social. Ambiente Construído , Porto Alegre, v. 15, n. 4, p. 19-35, out./dez. 2015.; Cavalheiro; Abiko, 2015CAVALHEIRO, D. de C.; ABIKO, A. Evaluating slum (favela) resettlements: the case of the Serra do Mar Project, São Paulo, Brazil. Habitat International , v. 49, p. 340-348, 2015.).

For instance, the construction of new rooms due to family composition, the need to separate the living room from the kitchen, bathroom alterations, and the adaptation of some rooms characterise interventions (Aragão; Hirota, 2016ARAGÃO, D. L. L. J. de; HIROTA, E. H. Sistematização de requisitos do usuário com o uso da Casa da Qualidade do QFD na etapa de concepção de unidades habitacionais de interesse social no âmbito do Programa Minha Casa, Minha Vida. Ambiente Construído, Porto Alegre, v. 16, n. 4, p. 271-291, out./dez. 2016.; Taube; Hirota, 2017TAUBE, J.; HIROTA, E. H. Customização em massa no processo de provisão de Habitações de Interesse Social: um estudo de caso. Ambiente Construído , Porto Alegre, v. 17, n. 4, p. 253-268, out./dez. 2017.; Bortoli; Villa, 2020BORTOLI, K. C. R. de; VILLA, S. B. Adequação ambiental como atributo facilitador da resiliência no ambiente construído em Habitações de Interesse Social. Ambiente Construído , Porto Alegre, v. 20, n. 1, p. 391-422, jan./mar. 2020.).Moreover, there are demands for outdoor transformations (Kowaltowski et al., 2006KOWALTOWSKI, D. C. C. K. et al. Quality of life and sustainability issues as seen by the population of low-income housing in the region of Campinas, Brazil. Habitat International , v. 30, n. 4, p. 1100-1114, 2006., 2021KOWALTOWSKI, D. C. C. K. et al. Housing transformation in search of well-being. In: ENCONTRO NACIONAL DE CONFORTO NO AMBIENTE CONSTRUÍDO, 16.; ENCONTRO LATINO-AMERICANO DE CONFORTO NO AMBIENTE CONSTRUÍDO, 12., Palmas, 2021. Anais [...] Palmas, 2021.), such as adapting pathways, constructing walls and sidewalks, changing the floor and wall finishes, and green areas (Nascimento et al., 2015NASCIMENTO, D. M. et al. Programa Minha Casa Minha Vida: desafios e avanços na Região Metropolitana de Belo Horizonte. In: AMORE, C. S.; SHIMBO, L. Z.; RUFINO, M. B. C. (ed.). Minha Casa... E a Cidade? Avaliação do Programa Minha Casa Minha Vida em seis estados brasileiros . Rio de Janeiro: Letra Capital , 2015. ; Bortoli; Villa, 2020BORTOLI, K. C. R. de; VILLA, S. B. Adequação ambiental como atributo facilitador da resiliência no ambiente construído em Habitações de Interesse Social. Ambiente Construído , Porto Alegre, v. 20, n. 1, p. 391-422, jan./mar. 2020.).

On the other hand, transformations may cause various negative impacts on the unit's performance (Muianga et al., 2022MUIANGA, E. A. D. et al. Housing transformations and their impacts on the well-being of dwellers. Ambiente Construído , Porto Alegre, v. 22, n. 4, p. 255-274, out./dez. 2022.). The construction of roofs to accommodate balconies and new rooms, use of low thermal and performance materials, and obstruction of windows and doors may increase discomfort, reduce cross ventilation and natural light, and affect housing infrastructure (Kowaltowski; Pina, 1995KOWALTOWSKI, D. C. C. K.; PINA, S. A. M. G. Transformações de casas populares: uma avaliação. In: ENCONTRO NACIONAL, 3.; ENCONTRO LATINO-AMERICANO DE CONFORTO NO AMBIENTE CONSTRUÍDO, 1., Gramado, 1995. Anais [...] Gramado, 1995.; Villa et al., 2017VILLA, S. B. et al. Co-production and resilience in a Brazilian social housing: the case of shopping park neighbourhood. In: PLEA INTERNATIONAL CONFERENCE: DESIGN TO THRIVE, 33., Edinburgh, 2017. Proceedings […] Edinburgh, 2017.). In addition, transformations may trigger pathologies and affect the health of these families (Muianga; Kowaltowski; Castro, 2022MUIANGA, E. A. D.; KOWALTOWSKI, D. C. C. K.; CASTRO, M. R. The covid-19 pandemic in relation to built environment design characteristics. In: ENCONTRO NACIONAL DE TECNOLOGIA DO AMBIENTE CONSTRUÍDO, 19., Canela, 2022. Anais […] Canela, 2022.). External transformation impacts housing design and functionality (Bortoli; Villa, 2020BORTOLI, K. C. R. de; VILLA, S. B. Adequação ambiental como atributo facilitador da resiliência no ambiente construído em Habitações de Interesse Social. Ambiente Construído , Porto Alegre, v. 20, n. 1, p. 391-422, jan./mar. 2020.).

Cost of living

Costs of living in SH exist. Live-in condominium models represent a new problem for residents (Paz et al., 2015PAZ, R. D. O. et al. Trabalho social no Programa Minha Casa Minha Vida: a experiência da cidade de Osasco/São Paulo. Em: AMORE, C. S.; SHIMBO, L. Z.; RUFINO, M. B. C. (ed.). Minha Casa... E a Cidade? Avaliação do Programa Minha Casa Minha Vida em seis estados brasileiros . Rio de Janeiro: Letra Capital , 2015.). Fees for services such as water, electricity, cable television, the provision of the property and condominium demands represent an increase in the cost of living, which in many cases makes it infeasible, in the medium and long run, for low-income families to remain in their new SH (Paz et al., 2015PAZ, R. D. O. et al. Trabalho social no Programa Minha Casa Minha Vida: a experiência da cidade de Osasco/São Paulo. Em: AMORE, C. S.; SHIMBO, L. Z.; RUFINO, M. B. C. (ed.). Minha Casa... E a Cidade? Avaliação do Programa Minha Casa Minha Vida em seis estados brasileiros . Rio de Janeiro: Letra Capital , 2015.).

Although not considered in several studies, SH residents face the risk and costs of insecurity, which reduce external and leisure space uses. Leisure spaces are also often unused due to the lack of maintenance and equipment (Müller; Lima, 2017MÜLLER, S. C.; LIMA, J. J. F. O espaço para crianças produzido pelo Programa Minha Casa, Minha Vida: estudo de caso na região metropolitana de Belém, PA. Ambiente Construído , Porto Aelgre, v. 17, n. 2, p. 97-117, abr./jun. 2017.). Moreover, insecurity increases the need to install surveillance equipment and actions to reduce risks. Insecurity may cause isolation and trigger mental health conditions, such as depression, fear, and anxiety (Muianga et al., 2021MUIANGA, E. A. D. et al. Critical analysis of housing condition impacts on residents’ well-being and social costs. Gestão & Tecnologia de Projetos , v. 16, n. 4, p. 33-66, out. 2021.).

Social participation

End-users have the highest interest in housing quality, however, with little power to influence the system, as social participation in the SH Programme's decision-making process is scarce. Understanding and intervening in the territory of a given group requires working with it. Analysing different perceptions and interventions of a built environment from a group of people may guide broadly participatory improvement actions among users, agents and public policies (Silveira; Carmo; Luz, 2019SILVEIRA, D. C.; CARMO, R. F.; LUZ, Z. M. P. Planning in four areas of the Vila Viva Program in the city of Belo Horizonte, Brazil: a documentary analysis. Ciência e Saúde Coletiva, v. 24, n. 3, p. 1165-1174, 2019.).

The MVMV program should be based on a participatory planning process. Considering the importance of social participation in housing policies, especially in MCMV, public policies should emphasise citizen participation within the scope of SH programmes, including the need for training so thatparticipationiseffective (Moreira; Silveira, 2015MOREIRA, V. D. S.; SILVEIRA, S. D. F. R. Indicadores de desempenho do Programa Minha Casa,Minha Vida: avaliação com base na satisfação dos beneficiários. Cadernos Gestão Pública e Cidadania, v. 20, n. 66, p. 94-117, 2015.; Silveira et al., 2018SILVEIRA, S. R. et al. Social participation in the program “Minha Casa, Minha Vida”: analysis of municipal housing councils. Praxis sociológica, n. 23, p. 101-121, 2018.). In this process, dwellers engage in all aspects of upgrading, from resource allocation to service delivery (Walker, 2016WALKER, A. P. W. Self-help or public housing? Lessons from co-managed slum upgrading via participatory budget. Habitat International , v. 55, p. 58-66, 2016.).

Guideline to overcome the negative impacts regarding Post Occupancy Evaluation (POE)

Actions, properly designed and developed by specialists under resident participation, may promote SH projects better suited to the resident’s needs in the long term (Kowaltowski; Granja, 2011KOWALTOWSKI, D. C. C. K.; GRANJA, A. D. The concept of desired value as a stimulus for change in social housing in Brazil. Habitat International , v. 35, n. 3, p. 435-446, 2011.; Aragão; Hirota, 2016ARAGÃO, D. L. L. J. de; HIROTA, E. H. Sistematização de requisitos do usuário com o uso da Casa da Qualidade do QFD na etapa de concepção de unidades habitacionais de interesse social no âmbito do Programa Minha Casa, Minha Vida. Ambiente Construído, Porto Alegre, v. 16, n. 4, p. 271-291, out./dez. 2016.; Walker, 2016WALKER, A. P. W. Self-help or public housing? Lessons from co-managed slum upgrading via participatory budget. Habitat International , v. 55, p. 58-66, 2016.; Vasconcellos et al., 2017VASCONCELLOS, A. et al. Social participation in the management of the Program Minha Casa Minha Vida (PMCMV) in Brazil: the case of Abaetetuba, Pará State. Revista Espacios , v. 38, n. 9, p. 1-12, 2017.; Taube; Hirota, 2017TAUBE, J.; HIROTA, E. H. Customização em massa no processo de provisão de Habitações de Interesse Social: um estudo de caso. Ambiente Construído , Porto Alegre, v. 17, n. 4, p. 253-268, out./dez. 2017.; Villa et al., 2017VILLA, S. B. et al. Co-production and resilience in a Brazilian social housing: the case of shopping park neighbourhood. In: PLEA INTERNATIONAL CONFERENCE: DESIGN TO THRIVE, 33., Edinburgh, 2017. Proceedings […] Edinburgh, 2017.; Silveira; Carmo; Luz, 2019SILVEIRA, D. C.; CARMO, R. F.; LUZ, Z. M. P. Planning in four areas of the Vila Viva Program in the city of Belo Horizonte, Brazil: a documentary analysis. Ciência e Saúde Coletiva, v. 24, n. 3, p. 1165-1174, 2019.). In this context, public policies should ensure the interaction between society and SH stakeholders, enabling participatory discussions and improvement actions (Moreira; Silveira, 2015MOREIRA, V. D. S.; SILVEIRA, S. D. F. R. Indicadores de desempenho do Programa Minha Casa,Minha Vida: avaliação com base na satisfação dos beneficiários. Cadernos Gestão Pública e Cidadania, v. 20, n. 66, p. 94-117, 2015.; Silveira et al., 2018SILVEIRA, S. R. et al. Social participation in the program “Minha Casa, Minha Vida”: analysis of municipal housing councils. Praxis sociológica, n. 23, p. 101-121, 2018.).

The importance of space flexibility and individualisation should be incorporated into SH programmes (Nascimento et al., 2015NASCIMENTO, D. M. et al. Programa Minha Casa Minha Vida: desafios e avanços na Região Metropolitana de Belo Horizonte. In: AMORE, C. S.; SHIMBO, L. Z.; RUFINO, M. B. C. (ed.). Minha Casa... E a Cidade? Avaliação do Programa Minha Casa Minha Vida em seis estados brasileiros . Rio de Janeiro: Letra Capital , 2015. ). Functionality, spaces for appliances, solar control in openings, visual and thermal comfort, natural lighting and ventilation, private leisure spaces, balconies, backyards, and spaces for pets and plants should be considered (Horongoso; Bogo, 2018HORONGOSO, B.; BOGO, A. J. Avaliação pós-ocupação das condições de habitação em conjuntos habitacionais do PMCMV em Blumenau SC. HOLOS, v. 8, p. 59-71, 2018.; Muianga et al., 2022MUIANGA, E. A. D. et al. Housing transformations and their impacts on the well-being of dwellers. Ambiente Construído , Porto Alegre, v. 22, n. 4, p. 255-274, out./dez. 2022.).

Outdoor areas of housing developments should have urban infrastructure and landscaping projects with shade trees. In outdoor areas, improved infrastructure and landscaping, as well as providing shading around the buildings from the afforestation are essential. Residents’ social networks, communal spaces, and leisure facilities need to be considered and may improve the habitability of SH as they represent a major value for dwellers (Berr et al., 2015BERR, L. R. et al. Indicador de falhas de qualidade baseado na percepção dos usuários de Habitação de Interesse Social. Ambiente Construído , Porto Alegre, v. 15, n. 4, p. 19-35, out./dez. 2015.; Cavalheiro; Abiko, 2015CAVALHEIRO, D. de C.; ABIKO, A. Evaluating slum (favela) resettlements: the case of the Serra do Mar Project, São Paulo, Brazil. Habitat International , v. 49, p. 340-348, 2015.). In general, detailed investigations of SH design and automatised methods of verifying requirements may provide projects that meet end-users’ desires (Kowaltowski; Granja, 2011KOWALTOWSKI, D. C. C. K.; GRANJA, A. D. The concept of desired value as a stimulus for change in social housing in Brazil. Habitat International , v. 35, n. 3, p. 435-446, 2011.; Fernandes; Formoso; Tzortzopoulos-Fazenda, 2018FERNANDES, G. von der H.; FORMOSO, C. T.; TZORTZOPOULOS-FAZENDA, P. Método para verificação automatizada de requisitos em empreendimentos Habitacionais de Interesse Social. Ambiente Construído , Porto Alegre, v. 18, n. 4, p. 259-278, out./dez. 2018.).

Use of resources

Considering local bioclimatic conditions and using energy efficiency strategies may reduce the use of resources to improve comfort (Giannetti et al., 2018GIANNETTI, B. F. et al. Towards more sustainable social housing projects: Recognizing the importance of using local resources. Building and Environment, v. 127, p. 187-203, 2018.). Furthermore, upgrading to improve energy efficiency to overcome the effects of climate changes should be explored and applied in Brazil, mainly in SH, to ensure comfort and reduce future energy infrastructure needs (Triana; Lamberts; Sassi, 2015TRIANA, M. A.; LAMBERTS, R.; SASSI, P. Characterisation of representative building typologies for social housing projects in Brazil and its energy performance.

Applying backcasting and system dynamics towards sustainable development: the housing planning case for low-income citizens in Brazil. Journal of Cleaner Production, v. 193, p. 97-114, 2018.).

Sustainability certification tools have been used to assess buildings and urban areas to promote more sustainable development goals and practices in civil construction and urban planning (Gomes; Adão, 2017GOMES, V.; ADÃO, M. Sustainability performance tracking of social housing: the tale of two projects in Brazil. In: PLEA INTERNATIONAL CONFERENCE: DESIGN TO THRIVE, 33., Edinburgh, 2017. Proceedings […] Edinburgh, 2017.; Gonçalves et al., 2020GONÇALVES, D. K. de O. et al. Qualitative and quantitative assessment of urban sustainability in social housing using the Casa Azul label and SBTool urban in Brazil. Applied Sciences, v. 10, n. 18, p. 6246, 2020.). However, in Brazil, the initial cost of implementing energy efficiency is still a major barrier (Bodach; Hamhaber, 2010BODACH, S.; HAMHABER, J. Energy efficiency in social housing: opportunities and barriers from a case study in Brazil. Energy Policy , v. 38, n. 12, p. 7898-7910, dez. 2010.).

User comfort levels of a housing unit should attend compliances with the Brazilian Association of Technical Standards (Associação Brasileira de Normas Técnicas - NBR, in Portuguese): NBR 15575 (Residential buildings - Performance), and NBR 15220 (Thermal performance of buildings), considering minimum conditions for summer and winter in all Brazilian Bioclimatic Zones (Oliveira et al., 2015aOLIVEIRA, R. D. et al. Concrete walls thermal performance analysis by Brazilian standards. Energy Procedia, v. 78, p. 213-218, nov. 2015a. , 2015bOLIVEIRA, R. D. et al. Thermal comfort for users according to the Brazilian housing buildings performance standards. Energy Procedia, v. 78, p. 2923-2928, nov. 2015b. ). Moreover, the Blue House Label (Selo Casa Azul in Portuguese) is a sustainability certification focusing on the social sector (Gomes; Adão, 2017GOMES, V.; ADÃO, M. Sustainability performance tracking of social housing: the tale of two projects in Brazil. In: PLEA INTERNATIONAL CONFERENCE: DESIGN TO THRIVE, 33., Edinburgh, 2017. Proceedings […] Edinburgh, 2017.; Gonçalves et al., 2020GONÇALVES, D. K. de O. et al. Qualitative and quantitative assessment of urban sustainability in social housing using the Casa Azul label and SBTool urban in Brazil. Applied Sciences, v. 10, n. 18, p. 6246, 2020.). However, NBR 15220 presents minimum values for parameters, which are considered inadequate, and improvement is needed to simplify and make instrument requirements compatible (Oliveira; Souza, 2019OLIVEIRA, J. A. de; SOUZA, C. G. de. A produção da habitação social numa cidade amazônica. Confins, Revista Franco-Brasilera de Geografia , v. 42, 2019.; Oliveira; Souza; Da Silva, 2017OLIVEIRA, R. D.; SOUZA, R. V. G. de; DA SILVA, R. M. Issues to be improved on the thermal performance standards for sustainable buildings consolidation: an overview of Brazil. Energy Procedia, v. 111, p. 71-80, mar. 2017.).

Most Brazilian housings use ceramic or concrete block walls covered by mortar, with a timber roof structure and ceramic tiles (Ruppenthal et al., 2015RUPPENTHAL, J. E. et al. Experiências sobre a implementação da filosofia lean em uma obra de condomínio horizontal de interesse social em Santa Maria - RS. Revista Espacios, v. 36, n. 16, p. 1-4, 2015.; Tubelo et al., 2018TUBELO, R. et al. Cost-effective envelope optimisation for social housing in Brazil’s moderate climates zones. Building and Environment , v. 133, p. 213-227, 2018.). This pattern of construction may not be suitable in some places with high temperatures all year round, which implies air conditioning installations, or in cold areas that imply heat systems in winter, consequently an increase in energy consumption (Dalbem et al., 2019DALBEM, R. et al. Optimisation of a social housing for south of Brazil: From basic performance standard to passive house concept. Energy, v. 167, p. 1278-1296, jan. 2019.; Mahecha et al., 2020MAHECHA, R. E. G. et al. Constructive systems for social housing deployment in developing countries: A case study using dynamic life cycle carbon assessment and cost analysis in Brazil. Energy and Buildings, v. 227, p. 110395, 2020.). New housing construction technologies are needed to attend sustainable agendas.

Guidelines to overcome the negative impacts regarding Sustainability issues

The current challenge of promoting Sustainable Development Goals (SDG) and reducing resource uses, impacts of global warming, and carbon emissions require upgrading a built environment (Siqueira-Gay; Gallardo; Giannotti, 2019SIQUEIRA-GAY, J.; GALLARDO, A. L. C. F.; GIANNOTTI, M. Integrating socio-environmental spatial information to support housing plans. Cities , v. 91, p. 106-115, 2019.; Siqueira-Gay; Sánchez, 2019RUFINO, M. B. C. et al. A produção do Programa PMCMV na Baixada Santista: habitação de interesse social ou negócio imobiliário? Em: AMORE, C. S.; SHIMBO, L. Z.; RUFINO, M. B. C. (ed.). Minha Casa... E a Cidade? Avaliação do Programa Minha Casa Minha Vida em seis estados brasileiros . Rio de Janeiro: Letra Capita, 2015. ). Thus, it is becoming increasingly necessary to consider the context of Life Cycle Assessment (LCA) in SH, and the use of local materials to reduce the application of scarce and non-renewable resources and energy consumption, and carbon emission, to meet SDGs (Giannetti et al., 2018GIANNETTI, B. F. et al. Towards more sustainable social housing projects: Recognizing the importance of using local resources. Building and Environment, v. 127, p. 187-203, 2018.; Azevedo; Geraldi; Ghisi, 2020AZEVEDO, L. D. de; GERALDI, M. S.; GHISI, E. Avaliação do Ciclo de Vida de diferentes envoltórias para habitações de interesse social em Florianópolis. Ambiente Construído , Porto Alegre, v. 20, n. 4, p. 123-141, out./dez. 2020.).

The Life Cycle Carbon Assessment (LCCA) may be applied to assess building quality and sustainability (Mahecha et al., 2020MAHECHA, R. E. G. et al. Constructive systems for social housing deployment in developing countries: A case study using dynamic life cycle carbon assessment and cost analysis in Brazil. Energy and Buildings, v. 227, p. 110395, 2020.). The LCCA considers all the carbon-equivalent greenhouse gas (GHG) emissions resulting from the materials, construction, and use of a building over the stages of the Life Cycle, including its demolition and disposal. The use of material with less embodied energy and higher durability may decrease the need for maintenance and materials replacement, and achievement of an adequate Life Cycle Energy Assessment (LCEA) (Paulsen; Sposto, 2013PAULSEN, J. S.; SPOSTO, R. M. A life cycle energy analysis of social housing in Brazil: case study for the program “mY HOUSE MY LIFE”. Energy and Buildings, v. 57, p. 95-102, 2013.). Moreover, waste material use should be considered, such as recyclable ecological tiles and low-tech and low-cost, made by toothpaste tubes, which may be used to create sun-reflective elements, thus reducing solar heat effects (Masotti et al., 2011MASOTTI, C. et al. Self-help retrofitting technologies for low-cost housing construction. the case study of Vila Novo Ouro Preto, Brasil. Procedia Engineering, v. 21, p. 625-632, jan. 2011. ).

Strategies to enhance the thermal performance of concrete block walls are crucial (Azevedo; Geraldi; Ghisi, 2020AZEVEDO, L. D. de; GERALDI, M. S.; GHISI, E. Avaliação do Ciclo de Vida de diferentes envoltórias para habitações de interesse social em Florianópolis. Ambiente Construído , Porto Alegre, v. 20, n. 4, p. 123-141, out./dez. 2020.; Mahecha et al., 2020MAHECHA, R. E. G. et al. Constructive systems for social housing deployment in developing countries: A case study using dynamic life cycle carbon assessment and cost analysis in Brazil. Energy and Buildings, v. 227, p. 110395, 2020.). A well-ventilated building with adequate windows that fulfil daylight, colour absorption of walls and, in some cases of roofs, improves thermal comfort for its users, reducing energy consumption by eliminating the need for air conditioning (Mesquita; Ripper Kós, 2017MESQUITA, L.; RIPPER KÓS, J. Towards more resilient and energy efficient social housing in Brazil. Energy Procedia, v. 121, p. 65-70, set. 2017. ; Morais; Labaki, 2017MORAIS, J. M. da S. C.; LABAKI, L. C. CFD como ferramenta para simular ventilação natural interna por ação dos ventos: estudos de caso em tipologias verticais do “Programa Minha Casa, Minha Vida”. Ambiente Construído , Porto Alegre, v. 17, n. 1, p. 223-244, jan./mar. 2017.; Dalbem et al., 2019DALBEM, R. et al. Optimisation of a social housing for south of Brazil: From basic performance standard to passive house concept. Energy, v. 167, p. 1278-1296, jan. 2019.).Implementing photovoltaic panels and replacing traditional materials with more efficient ones may represent energy savings and reduce the need for indoor cooling (Pinto; Amaral; Janissek, 2016PINTO, J. T. M.; AMARAL, K. J.; JANISSEK, P. R. Deployment of photovoltaics in Brazil: Scenarios, perspectives and policies for low-income housing.

Energy Policy , v. 108, p. 292-298, 2017.; Triana; Lamberts; Sassi, 2018TRIANA, M. A.; LAMBERTS, R.; SASSI, P. Should we consider climate change for Brazilian social housing? Assessment of energy efficiency adaptation measures. Energy and Buildings, v. 158, p. 1379-1392, 2018.; Dalbem et al., 2019DALBEM, R. et al. Optimisation of a social housing for south of Brazil: From basic performance standard to passive house concept. Energy, v. 167, p. 1278-1296, jan. 2019.; Bavaresco et al., 2021BAVARESCO, M. V. et al. Aspectos impactantes no desempenho energético de habitações de interesse social brasileiras: revisão de literatura. Ambiente Construído , Porto Alegre, v. 21, n. 1, p. 263-292, jan./mar. 2021.).

Improvements in urban morphology, such as the introduction of shaded or sunlit open areas, may promote better outdoor thermal conditions that indirectly influence indoor environments, reducing energy use (Krüger, 2015KRÜGER, E. L. Urban heat island and indoor comfort effects in social housing dwellings. Landscape and Urban Planning, v. 134, p. 147-156, 2015.). Moreover, for most bioclimatic zones in Brazil, adequate natural ventilation performance is essential, giving importance to cross-ventilation (Dalbem et al., 2019DALBEM, R. et al. Optimisation of a social housing for south of Brazil: From basic performance standard to passive house concept. Energy, v. 167, p. 1278-1296, jan. 2019.). Alternatives such as heating during winter, season adaptation for thermal comfort, water use efficiency, and rainwater harvesting are necessary (Oliveira et al., 2015aOLIVEIRA, R. D. et al. Concrete walls thermal performance analysis by Brazilian standards. Energy Procedia, v. 78, p. 213-218, nov. 2015a. , 2015bOLIVEIRA, R. D. et al. Thermal comfort for users according to the Brazilian housing buildings performance standards. Energy Procedia, v. 78, p. 2923-2928, nov. 2015b. ; Moreno; Morais; Souza, 2017MORENO, A. C. R.; MORAIS, I. S. de; SOUZA, R. G. de. Thermal performance of social housing: a study based on brazilian regulations. Energy Procedia, v. 111, p. 111-120, mar. 2017. ).

Thus, metamodels to analyse the thermal performance of SH through sun orientation, shading and envelope materials, and natural ventilation models may provide thermal comfort options and should be applied during the early stages of the design process (Krüger; Laroca, 2010KRÜGER, E. L.; LAROCA, C. Thermal performance evaluation of a low-cost housing prototype made with plywood panels in Southern Brazil. Applied Energy , v. 87, n. 2, p. 661-672, 2010.; Krüger, 2015KRÜGER, E. L. Urban heat island and indoor comfort effects in social housing dwellings. Landscape and Urban Planning, v. 134, p. 147-156, 2015.; Rossi et al., 2019ROSSI, M. M. et al. Metamodels to assess the thermal performance of naturally ventilated, low-cost houses in Brazil. Energy and Buildings, v. 204, p. 109457, 2019.; Nunes et al., 2020NUNES, G. et al. Thermo-energetic performance of wooden dwellings: benefits of cross-laminated timber in Brazilian climates. Journal of Building Engineering, v. 32, p. 101468, 2020.). The public policies for SH in Brazil have included domestic Solar Water Heaters (DSWH) (Giglio et al., 2014GIGLIO, T. et al. A procedure for analysing energy savings in multiple small solar water heaters installed in low-income housing in Brazil. Energy Policy , v. 72, p. 43-55, set. 2014.; Giglio; Lamberts, 2016GIGLIO, T.; LAMBERTS, R. Savings related to solar water heating system: a case study of low-income families in Brazil. Energy and Buildings, v. 130, p. 434-442, out. 2016.). Adopting DSWH systems may provide annual energy savings and lower carbon emissions, representing a real benefit for end-users and distribution utility firms (Bessa; Prado, 2015BESSA, V. M. T.; PRADO, R. T. A. Reduction of carbon dioxide emissions by solar water heating systems and passive technologies in social housing. Energy Policy, v. 83, p. 138-150, ago. 2015.; Naspolini; Rüther, 2017NASPOLINI, H. F.; RÜTHER, R. Impacts of Domestic Solar Water Heating (DSWH) systems on the cost of a hot shower in low-income dwellings in Brazil. Renewable Energy , v. 111, p. 124-130, 2017.).

Description of SH issues: qualitative analysis

From each cluster of topics presented in Figure 3, eleven issues were identified and analysed. Urban accessibility analysed issues of urban design, ZEIS, and urban infrastructure and equipment. In relation to public policies and SH programmes’ topics, issues of housing deficit, the National Rural Housing Program, and mass reproduction were identified. The topic of Brazilian SH financing analysed issues related to the real estate market and delinquent contracts. Post-occupancy evaluation (POE) topics analysed house transformations, cost of living and social participation issues. The topic of resources uses analysed issues of sustainable development goals, thermal comfort, and energy efficiency. For each topic, the main impacts of SH, the cause that those impacts trigger, the phase of the project cycle and guidelines for improvements are presented (Figure 7).

In Figure 7, it can be inferred that categories may share negative impacts from different origins. Furthermore, it is perceived that impacts also may trigger other sub-problems. However, despite impacts being identified based on perceptions and findings from different areas of knowledge, there is an alignment of guidelines that should be applied to mitigate them. The assessment clearly evaluates how a particular intervention might address various interrelated problems.

SH programmes, especially for a lower-income group among the beneficiaries, require changes in their production as a matter of urgency. The SH fails, and impacts are presented over the stages of its Life Cycle, from conception to use. Thus, it becomes increasingly necessary for public policies and housing programme actions to attend to the dwellers’ demands, not only in producing and delivering new housing but also in relation to what already exists.

The impacts of accessibility may be minimised by inclusive planning, where the resident becomes the protagonist in defining a neighbourhood according to their needs. Assessing the families' habits and displacements is essential to ensure SH definitions and improvements. Furthermore, it is important to emphasise sustainable neighbourhoods, providing access to amenities with less use of motorised transport. Therefore, the requalification of neighbourhoods where SHs are allocated should be part of public policies to reduce the impacts of housing quality and location. SH projects should be improved to ensure functionality and comfort and, consequently, the well-being of families.

Figure 7
Association of SH issues

The cost of housing must not be a barrier to improvements, which are often demonstrated through research to be feasible, both in new projects and in existing ones. Funds to improve SH projects are important to elevate the quality of developments to provide adequate design and construction standards, improve people’s wellbeing, environmental sustainability and reduce social costs. Funds to improve SHs are increasingly necessary, considering that the challenges faced by residents are recurring and have an impact throughout the life cycle, both in terms of well-being, sustainability, use of natural resources and social costs.

Figure 8 presents a panorama of SH programmes and their impacts through topic analysis. As presented, the actions and decisions of public policies and financing made during the project’s initial phase may trigger negative impacts throughout housing production and use (post-occupancy) and affect urban accessibility issues.

The lack of decisive participation of public policies when defining SH projects allows private agents to be the main decision-makers. Processes with the effective participation of beneficiaries of SH still do not occur, and houses are developed without the correct knowledge of resident needs in terms of units and neighbourhoods. The post-occupancy phase presents negative impacts which could be avoided if the production of SH were to consider social, economic and environmental issues necessary to ensure the quality of life and well-being of its beneficiaries.

The unit, building, neighbourhood and urban contexts affect SH residents in terms of health, productivity, income, educational opportunities, displacement, and right to the city, among other issues, and should be optimised. The introduction of improvements is essential to mitigate recurrent daily life problems that the SH populations face. Improvements to the existing SHs should be considered to reduce recurring problems that most residents of these complexes face in their daily lives. These improvements must be incorporated into new SH designs.

Final remarks

Urban accessibility, public policies, and the production of SH programmes stimulated many studies on Brazilian SH topics. Worldwide, the responsibility to improve environmental issues fosters studies covering various fields, focusing on energy efficiency and strategies for implementing sustainable projects.

Figure 8
Main failures and impacts of SH programmes

Although issues involving indoor and outdoor SH conditions are raised in POE studies, most studies concentrate on external area issues and the location of SH units. Few studies detail the impacts of the physical environment of the units or present opportunities for improvements aimed at beneficiaries' quality of life. In addition, financing and high defaulting rates drive research in economics, although with less impact.

Public policies and SH programme definitions influence all SH development and trigger negative impacts. The lack of public policy actions, user participation in SH design definition and production, and reduced considerations concerning urban necessities result in the repetition of errors and reduced value for end-users.

In the absence of changes in the production of SH, in which public authorities and users could lead the main decisions on design and location, many of the recurrent problems will be repeated in future projects. An overarching involvement and large investments in infrastructure and the creation of public and private spaces, as well as essential services for segregated sites, are essential to reduce the daily costs of access to basic facilities. Thus, efforts to benefit beneficiaries of these SH estates, improve their quality of life, and the sustainability of these projects should ultimately increase satisfaction rates, constituting a goal for the built environment and societal advancement. Thus, the development of public housing policies linked to the social interests of society is urgent.
