Abstract: All new and renovated buildings must comply with the verification of summer heat protection as stated in DIN 4108-2, according to the Building Energy Act (GEG). The solar gain factor (simplified method) and dynamic simulation are the two approaches now in use. Using a data set of 10,000 configurations generated in IDA ICE, the accuracy of the simplified method was determined in this study. Following that, three different regression models were performed on the data set with the aim of generating a model that better represented the dynamic simulation findings. The results demonstrate that the simplified method can improve accuracy on this data set, however the boundary conditions must be adjusted to increase representation of real buildings.
