Abstract

By daylight harvesting, the annual electric power usage of luminaires can be reduced, on the other hand, window solar heat gain increases. In recently, as the demand for environmentally conscious buildings has increased, comprehensive evaluation of solar heat gain and natural lighting for facades equipped with various outside sun shading is desired. Therefore, by combining the calculation results of Radiance using BIM's model with NewHASP, and connecting a heat gain calculation result with LCEM to develop a simulation model that accurately evaluates electric power usage, we made it possible to investigate the energy performance of outside sun shading in detail.
