Abstract

The urban heat island is mainly caused by increase of air conditioning load with increase of surface temperature and heat radiation in the night related to large amount of absorption of insolation radiation in the daytime on the external surface. As a method of mitigation of these effects, covering building envelopes with high reflection materials is effective. In this study, on-site measurement is made for cool surfaces covered with painted layer and waterproof sheet with high reflectivity for the insolation. Calibration of reflectivity including the influence of the surroundings is performed by using standard reflecting plates with known reflectivity. Error factors in the measurement are evaluated.
