摘　　要：为了探讨绿化屋顶在提升建筑节能性方面的作用,建立绿化屋顶的传热模型,详细分析植物层的能量平衡、热阻参数、热衰减、延迟特性以及内表面热流密度,并探讨绿化屋顶围护结构的热工特性,揭示绿化屋顶在建筑节能方面的潜在优势。结果表明,绿化屋顶能够有效减少室外热量向室内的传递,延长热量传递的延迟时间,从而显著提升建筑的节能性能。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.
