This paper aims to provide information to support discussions on setting targets for the introduction of photovoltaic (PV) systems in non-residential buildings. By analyzing application data from building energy standards, the study investigates three aspects for non-residential buildings newly constructed between FY2018 and FY2022: 1) the introduction rate of PV systems, 2) the distribution of design specifications such as system generation capacity and tilt and azimuth angle, and 3) their impact on the Building Energy Index (BEI).
