Abstract

Building-integrated photovoltaics (BIPV) has attracted increasing attention owing to its ability to integrate electricity generation with building-envelope functions. However, there remains no standardized framework for assessing their cost and economic feasibility in office buildings. This study analyzes the installation cost and long-term economic feasibility of façade- and rooftop-type BIPV systems in medium- and high-rise office building models using a cost-estimation program and PVsyst simulation. The results indicate that, in both cases, the 25-year cumulative electricity cost-saving benefits of façade- and rooftop-type BIPV systems largely offset the additional costs of conventional glass curtain walls. In particular, façade-type BIPV has greater economic potential as a building-envelope component when the replacement of conventional exterior materials is considered. These findings highlight that BIPV should be evaluated not only as a power-generation system, but also as a building-envelope component that replaces conventional cladding while generating electricity.
