Dynamic Performance of the Shading-type Building-integrated Photovoltaic Claddings

摘要

Application of the shading-type Building-Integrated Photovoltaic (BIPV) claddings is one of the most effective approaches for reducing energy use in buildings and making buildings environment-friendly. PV modules are used as external shading devices and insulation panels as well. In this paper, the energy performance of the shading-type BIPV claddings is investigated under dynamic conditions. The design parameters of the shading-type BIPV claddings, including the tilt angles and azimuth angles of PV modules, the window to wall ratio of the building and the overhang length, are discussed based on the meteorological conditions of Hong Kong. Optimum designs of the shading-type BIPV claddings are reported for buildings with different orientations and window to wall ratios.
