Kollektivhuset Stacken, a classic, 50-year old Swedish “million program” building with 35 apartments in Göteborg, which has long been run as a cooperative, has demonstrated a cost effective step by step deep retrofit to the international Passive House standard with a building integrated PV (BIPV) façade and roof. The existing concrete façade was externally insulated and covered with thin film amorphous silicon solar modules and more effective crystalline silicon solar modules were installed on the roof. New passive house certified doors and windows, demand-controlled ventilation coupled to a heat recovery unit and vacancy sensor based lighting was installed throughout the building. Finally, sensors to monitor the solar arrays, as well other parameters such as cold and hot water use, ventilation flows, electricity, temperature and humidity in each apartment were also installed. The research project presented in this article is a collaboration between Göteborgs University, RISE, and Emulsionen that uses knowledge and data gathered from the project towards evaluation of the performance and reliability of the BIPV system.
