Analysis on thermal measuring of green roof

Abstract

Comparison of thermal performance between a green roof room and a bare roof room was presented during the cooling period in Shanghai. The results show that the electricity can be saved about 0.08 kW.h/(d.m(2)), and the heat flux can be reduced by about 70%; the inner surface temperature variation is about 1.0 degrees C comparing with the indoor temperature when using the green roof, and the extra equivalent heat resistance is 1.0 m(2).K/W.
