摘要：冬季现场调研与热环境测试表明，拉萨市现有居住建筑的缓冲空间能明显改善室内热环境。但当地非采暖房间冬季热环境仍较差，居住建筑采暖需求明显。当地采暖能耗与环境负荷增长趋势明显。以拉萨市常见的单元式住宅为基础建立了热工计算模型，模拟分析了南北向缓冲空间进深设计对冬季采暖能耗的影响规律。结果表明：南北向缓冲空间均能有效降低模型的采暖能耗，其中，随着南向缓冲进深增大，模型采暖能耗呈递增趋势；随北向媛冲空间进深增大，模型采暖能耗呈先降后增趋势，北向缓冲空间模型之间能耗差很小。缓冲空间优化设计模型与基础模型的
能耗对比分析显示，合理设置的南北向缓冲空间能够大幅降低采暖能耗。关键词：缓冲空间；采暖能耗；被动式设计；建筑节能

Abstract:Based on the analysis of winter field survey and thermal environment measurement, the buffer space design can obviously improve indoor thermal environment in the residential buildings of Lhasa. However, the indoor winter thermal environment of non-heating rooms still need to be improved. Local people have strong heating demand for residential buildings. All the clues lead to the fast growing tendency of heating energy consumption and environmental load in Lhasa. The basic simulation models for understanding the buffer-space's effect to heating energy consumption are established from the common residential buildings in Lhasa+ and the factors include south and north buffer-space's depth design. Result shows that buffer-space can obviously reduce winter heating energy consumption. Along with the south buffer-space's depth increasing, the heating energy consumption shows the tendency of continuous
