Active and passive solar energy integration in single-family dwelling roofs of real estate developments

Abstract

This study analyses the possibility of achieving negative energy demands in single-family housing (Plus-Energy House). Through the integration of energy efficiency measures jointly with active solar systems, it is possible to obtain high performance energy models. In order to demonstrate this, we performed energy simulations integrating active solar systems, and also possible self-shading and separations between dwellings. We analysed the deployment of BIPV, BISTw, BIPVTa and BIPVTw technologies individually and in different combinations between them with the purpose of maximizing production capability for self-consumption, comparing them with residential demands in order to identify energy deficits and surpluses in different seasons. The measurements were taken hourly on typical days in summer, winter and intermediary seasons. Finally, an annual balance was obtained, showing energy surpluses of approximately 174 % when deploying only BIPV collectors and 251 % when combining BIPVTw and BIPVTa.
