STUDY ON THE ESTIMATION OF SOLAR REFLECTANCE REDUCTION ON COOL COATED CORRUGATED ROOF

Abstract

The effect of multiple absorption by the shape of corrugated roof coated with high reflective paint was studied. It is largely affected by multiple absorption in the case of 0.5 to 0.7 solar reflectance of the roof material. If the high reflectivity paint is applied to the corrugated roof, urban heat island measure effects and energy saving effects should be evaluated by using the solar reflectance which is considered the effect of multiple absorption noted in this study.
