Feasibility Study of Solar Photovoltaic Systems in University Buildings under the ESG Framework

บทคัดย่อ

        The deployment of solar photovoltaic (PV) systems in university buildings represents a critical component of the transition toward sustainable campus energy management. Grounded in the Environmental, Social, and Governance (ESG) framework, this study aims to comprehensively assess the feasibility and performance of a rooftop PV system at a university in China. A mixed-methods approach was employed, including PVsyst-based energy simulation, a structured questionnaire survey (n = 486), and multiple linear regression analysis. The simulation results estimate an annual electricity output of 773,503 kWh, corresponding to a reduction of 603.33 tons of CO₂ emissions. Survey data reveal a generally high level of user satisfaction, with statistically significant gender differences observed in perceptions of resource conservation (p = 0.033). Regression analysis identifies electricity usage time as the most influential factor affecting consumption (β = 0.692, p < 0.001). The findings underscore the environmental and social benefits of PV implementation in university contexts, while also highlighting the necessity of data-driven governance strategies to enhance energy efficiency and system sustainability.
