Modeled hourly solar radiation

Building energy simulation has proved useful in the development of building energy codes (especiallyperformance-based) and subsequent code compliance checking. A weather year is required for thehourly computation of heating/cooling loads and corresponding energy consumption. Many locationshave measured daily solar radiation data, but not hourly. Attempts were made to model hourly globalsolar radiation (GSR) data from measured daily values using the Liu and Jordan method for Harbin,Beijing, Shanghai, Kunming and Hong Kong.
