Abstract
Green façades have been well proven to be efficient in preventing overheating of buildings from excessive solar radiation. The effect of orientation on thermal performance of green façade in hot and humid climate is examined in the present study. Field measurement was carried out in Suzhou, on south-facing and east-facing walls, which are covered by green façades in different orients. The results show that green façades can effectively reduce temperature increment in the daytime compared with bare wall. Compared with green façades in east orient, green façades in south orient have better thermal performance in daytime and nighttime. Relative humidity under leaf layer increased significantly for green façades. And relative humidity of surrounding air could be influenced within a small distance (not exceeding 15 cm) by green façades. This study provides useful information for scientist to further investigate microclimate alteration effect of green façades.
