Optimization of outside and inside sun shading devices using radiance and newhasp

Abstract

Daylight harvesting is attracting attention from both energy saving and the viewpoint of improving the health and wellness of people in buildings. First, we made it possible to investigate the energy performance of outside and inside sun shadings in detail, by combining the annual calculation results by Radiance and NewHASP. Then the evaluation module of visual environment, such as glare and view, was incorporated in the system using Radiance. Finally, multi'objective optimization simulation system is constructed for finding the optimal shape of the composite window system combining outside vertical louvers and inside Venetian blind.
