Analyzing Resident Acceptance of Building- Integrated Photovoltaic(BIPV) in Apartment Housing

This study aims to analyze the relative importance of key factors influencing residents' acceptance of building-integrated photovoltaics (BIPV) in apartment housing.The Analytic Hierarchy Process (AHP) based survey was administered to residents of Godeok Onbitchae, a Grade 3 zero-energy building (ZEB) apartment complex, to evaluate five upper-level factorstechnical, economic, social, environmental, and policy-related factors-and their respective sub-factors.Unlike previous studies based on hypothetical scenarios or general populations, this study examines a residential complex in which BIPV systems have already been installed as part of the building envelope, allowing residents to directly experience the technology in their daily lives.Follow-up questions were also included to assess residents' experiences, awareness, and perceived policy needs related to BIPV.The results showed that the economic factor was the most important among the upper-level factors, while household electricity bill reduction, apartment management fee reduction, and carbon reduction effects ranked highest among the sub-factors.The findings further suggest that residents regard environmental effects as an important criterion alongside economic benefits.However, the follow-up survey indicated that residents perceived limited economic benefits despite assigning them high importance, highlighting the need for clearer information on actual cost savings.The policy-related findings further identified financial support for installation costs as the most needed measure for improving acceptance.This study contributes to the literature by identifying the key factors influencing residents' acceptance of BIPV in apartment housing from the residents' perspective.
