Thermal characteristics and building energy efficiency analysis of green roof envelope structure
XIAO Bao-chan
Abstract：In order to explore the role of green roof in improving building energy efficiency,a heat transfer model of green roof was established,and the energy balance,thermal resistance parameters,thermal attenuation,delay characteristics and inner surface heat flux of the plant layer were analyzed in detail.The thermal characteristics of green roof envelope were also discussed,and the potential advantages of green roof in building energy efficiency were revealed.The results show that green roof can effectively reduce the transfer of outdoor heat to indoor,prolong the delay time of heat transfer,and thus significantly improve the energy-saving performance of buildings.
