EVALUATION OF REDUCTION EFFECT ON THERMAL LOAD TO THE ATMOSPHERE BY WOODY FACING BUILDING

Abstract

In this research, it is proposed that atmospheric heat load is mitigated by using heat treated wood material for exterior coating of buildings. The heat budgets of wood deck and wall panel, which are actually constructed on horizontal rooftop and vertical wall, were evaluated. Numerical evaluations for heat budget on horizontal surfaces with and without wood deck in the case of same solar reflectance are performed. As are result, surface temperature and environmental thermal load in daytime on wood surface tends to be large, and the heat storage of building in daytime is suppressed and the heat discharge in night is reduced.
