This paper examines the influence of modeling daylighting in two energy simulation programs: EnergyPlus and Daysim. Different controls of the daylighting system will be tested and the results will be based on the total building energy consumption. The daylighting results from the EnergyPlus program show limitations for zones that have great depth as it overestimates the illuminance values in areas far from the window. Thus, the modelling of daylighting using Daysim was combined with the EnergyPlus program to estimate the whole building energy performance. These results demonstrated higher accuracy and the influence of the use of the Daysim daylighting result can be noted in the building energy consumption.
