Abstract

Presently, heat island phenomenon, leading towards global warming, is one of the major environmental problems. As a solution of this problem, roof and surface wall planting is considered to be effective. Accordingly, the objective of this study is to examine the effectiveness of roof planting in reducing the heat island phenomenon. The results of the study show that, planted area of the observed house roof had lower average temperature, in between $l5-20^{\circ}C,$ in comparison with that of the unplanted area of the roof.
