Evaluation of IES Validation in Term of Daylight Analysis by Experimental Measurement in State Office Building in Kerman, Iran

All simulation software should be evaluated by various methods  called empirical validation, analytical verification and comparative testing. However, validation of IES has been evaluated by some scholars and scientific organization such as ASHRAE and CIBSE in order to utilize Integrated Environmental Solution (IES ) as simulation software for daylight analysis in climatic condition of Kerman in  Iran. Empirical validation was selected in this research. Therefore, two office rooms which were available in one of government office building in Kerman city of Iran were chosen for experimental measurement. Then, these two office rooms were modelled in IES simulation software for comparison. The results were derived from simulation and experimental measurement. Finding of this research shows that IES has acceptable results in term of daylight analysis.
