A study was carried out in an office building to investigate daylight impact comparing SUPERLITE 1.01 and LUMENMICRO 5 simulation results with measured data.Referring to the CIE standard Clear (with direct sun) and Overcast sky luminance distributions, calculated illuminance and daylight factor data for the work plane are compared with on-site data collected under real sky conditions. The main aim of the paper is not a comparative evaluation of simulation programs, but to define the meaning and/or uncertainty attached to the quoted results from the programs.
