Estimation of surface solar irradiation using sky view factor, sunshine factor and solar irradiation models according to geometry and buildings

ABSTRACT This study aims to estimate surface solar irradiation using sky view factor (SVF), sunshine factor (SF) and solar irradiation models by the fish-eye image. The SVF and the SF contribute the solar irradiation for shielding from the sky and obtaining from the sunshine. It is possible to generate the SVF and the SF values for calculating from the simple geometric measurements, fisheye images, and simple model. The case study is a new building in Ulsan and looking for the best orientation and slope using the drone with a fisheye lens. The study demonstrates that the SVF and the SF analysis using fish-eye image is a useful and effective tool for design, optimization and performance evaluation of solar technologies and building energy for any geographical locations and buildings.
