摘　　要：随着建筑规模和体量的增长,建筑能耗日益攀升。屋顶作为建筑围护结构的主要构件,是建筑节能设计的主要对象之一。与传统屋顶相比,种植屋面能有效缓解城市热岛效应、降低建筑能耗。该文采用Energy Plus能耗模拟软件对长沙某办公建筑模型进行全年能耗模拟,分析了植物叶面积指数、基质层厚度、保温层厚度对种植屋面节能率的影响。结果表明:叶面积指数越大,供冷能耗越小;基质层和保温层越厚,供热能耗越小。As the building scale and volume grow consistently,building energy consumption is increasingly rising.As a major component of the building envelope enclosure,the roof is one of the main objects in the building energy-saving design.Compared with the traditional roof,the planted roof can effectively alleviate the urban heat island effect and reduce building energy consumption.In this paper,Energy Plus,an energy consumption simulation software,was used to simulate the annual energy consumption of an office building in Changsha,analyzing the impact of leaf area index(LAI),thickness of the substrate layer,and thickness of the insulation layer on the building energy saving rate.The results showed that the greater the LAI,the less the cooling energy consumption,and the thicker the substrate layer and the insulation layer,the less the heating energy consumption.
