| Abstract: | Energy consumption and thermal parameters of green roof and bare roof were measured in the air-conditioned and nature indoor environment in summer.It was found that the heat flow of green roof was reduced about 70%,and additional equivalent thermal resistance of green roof was about 1.0 m2·K/W in the air-conditioned,cooling efficiency of green roof was about 111% in the nature condition. |
| |
| Keywords: | green roof energy efficiency equivalent thermal resistance |
