ABSTRACT
The challenge of global warming has forced the construction industry with large carbon emissions to develop low-carbon and environmentally friendly architectural forms. Photovoltaic buildings make full use of renewable energy and have huge potential for emission reduction. However, the characteristics of BIPV technology, such as a relatively high initial investment and technical difficulties, hinder its widespread application. Previous studies have explored the potential benefits of BIPV technology; however, there is a lack of systematic investigation into the interactive relationships between the various factors related to this technology. To address this gap, critical influencing factors were identified based on a systematic literature review and semi-structured interviews, and questionnaires were distributed to experts to determine the interrelationships among the factors. Combining the data collected, a hybrid model that integrates decision-making trial and evaluation laboratory and interpretive structural modeling (DEMATEL-ISM), was developed to quantitatively assess interactions and determine the hierarchical structures and pathways of factors. The results show that the lowest-level root causes of BIPV technology promotion are the PV module power generation efficiency, PV power generation safety, and power quality. As a green technology, the advantages of the performance of BIPV power generation are a key to the successful promotion of this technology; thus, financial and human resources should be increased to optimize these technical challenges. The findings of this study provide valuable information for policymakers and practitioners to prioritize these issues and take effective measures to facilitate the promotion and development of BIPV technology.
