چکیده
For analyzing cooling loads, day-lighting, and building-integrated photovoltaic (BIPV) systems, solar radiation daylight illuminance data are required. However, these sparse. Furthermore, studies have shown that the energy potential of systems for entire building skin (BS) unconventional orientations, such as east, west, north need further exploration. Thus, this study presents findings from measured an analysis semi-transparent BIPV. Firstly, June 2019 to May 2020 in Hong Kong presented. The analyzed solar-radiation were used determine solar-energy BIPV BS four principal orientations (i.e., N, E, S W). With a simple analytical approach, data’s building-energy implications assessed. showed annual average horizontal global-, diffuse-, direct-irradiance values 291.8, 164.3, 127.5 W/m2/day, respectively. Similarly, 120, 72, 107 klux obtained peak global, diffuse, direct illuminance, results show using on Kong. It was also observed façade integrated with daylight-linked lighting controls could offer significant savings electric while producing energy. In particular, façades large window-to-wall ratio (WWR) 80% can provide overall benefit up 7126 kWh.
