STUDY ON DESIGN OF ENERGY-SAVING ROOFS OF RESIDENCE BUILDINGS IN HUNAN
-
摘要: 选取湖南省长沙市某节能住宅小区一普通居民住宅为分析对象,通过运用动态能耗模拟分析软件ENERGYPLUS建立模型,模拟计算住宅顶层房间的热环境和不同类型屋顶的住宅能耗。并通过经济分析,计算了各类型屋面的静态回收期。最后,整合归纳出适应湖南地区气候特点的住宅屋顶设计策略,以期解决湖南地区长期普遍存在的屋顶保温隔热性能差的现状问题,从而为湖南地区住宅屋顶设计提供参考。Abstract: A normal residence building in a energy-serving community in Changsha City, Hunan Province waschosen.Through the application of the model based on dynamic energy consumption stimulation softwareENERGYPLUS, the thermal environment of top-floor rooms and energy consumption of various roofings were simulatedand calculated.Through the economic analysis of all roofs, the static payback periods of all roofs were calculated.Inthe end, a designing strategy of building roofs that is suitable for Hunan area was concluded.It is hoped to improvethe poor thermal insulation quality of roofs that widely exists in Hunan area for a long time as to supply reference forthe designing of the roofs of residence buildings.
