“…Sustainable roofing can reduce energy consumption, improve the built environment's quality, and positively impact the environment. Graziano et al showed lower indoor temperatures for large green roofs compared to conventional cement tiles, with a difference between 6 and 8 degrees Celsius [2]. Lin et al showed that using photovoltaic roofing in a building renovation project saves about 60% of the building's energy consumption, which is economically feasible considering local energy tariff policies [3].…”

“…Second, the hybrid fuzzy decision experimental and evaluation laboratory (DEMATEL), the interpretive structural model (ISM), and the analytic network process (ANP) methods are used to analyze the interrelationships and impacts of the identified barriers. Specifically, (1) the fuzzy DEMATEL method is used to determine the significance of factors and quantify the causal relationship between these factors to determine the causal and outcome factors for promoting photovoltaic green roof renovation in existing buildings; (2) a multilevel recursive outcome model is established using the DEMATEL-ISM, revealing the complex mechanisms of action between different factors; (3) the ISM-MICMAC model is used to partition autonomous, dependent, correlated, and independent factors, clarifying the substantive role of factors in the system; (4) the DEMATEL and ANP methods are combined to obtain the mixed weights of each factor. The remainder of this study is divided into the following sections: Section 2 details the identification of contributing elements.…”

Photovoltaic green roofs can contribute to energy conservation in buildings and the sustainable development of cities, but they have yet to be widely used due to many factors. Therefore, it is necessary to investigate the factors limiting the promotion of photovoltaic green roofs and to clarify their interactions. Based on the existing literature and expert recommendations, this paper summarizes 20 factors affecting its promotion. Fuzzy DEMATEL was used to analyze the causal relationship and importance of the influencing factors. A hierarchical structure was established using the interpretative structural model (ISM) to visually represent the layered structure and pathways of the factors. The role and status of each influencing factor were determined using the cross-influence matrix analysis method (MICMAC). Finally, the analytic network process (ANP) was combined with the overall influence matrix to determine the overall weight of each factor. Combined with the DEMATEL-ISM-ANP method, nine key influencing factors, namely, the lack of incentive policies, imperfect technical specifications and evaluation standard system, local economic development level, residents’ cognition, residents’ willingness, enterprises’ technical problems, the lack of relevant talents, the lack of capital investment, and cooperation mode, were finally identified and analyzed, and suggestions and strategies for improvement were proposed.
