Comparison of Climate-Based Daylighting in Two Integrated Simulation Tools: DIVA and OpenStudio

Integrated daylighting and energy simulation tools aim to accomplish a thorough and accurate whole- building energy analysis in buildings and resolve the problems associated with discrete processes. OpenStudio and DIVA are two simulation tools that provide integrated daylighting and energy simulation. The objective of this study is to compare OpenStudio and DIVA software in daylighting performance simulation with results from physical experiment. Through this study Useful Daylight Illuminance (UDI) as an indication of useful annual climate-base daylight was calculated for a toplighting model in DIVA, OpenStudio and experiment. Identical Radiance parameters have been used for both simulations. The results show that the daylight quantities predicted by DIVA are closer to the measured experimental data collected from monitoring the physical model on a year-round basis.
