夏热冬冷地区由于气候和社会原因，近年来建筑能耗居高不下，在我国建筑节能工作中占有重要地位。国家和地方建筑节能标准对建筑能耗有很大的影响。本研究调查了夏热冬冷地区在不同能效标准（中国地方标准、中国国家标准和英国标准）下的节能潜力。以重庆市为例，应用商业能源模拟工具eQuest对建筑终端能耗进行了分析。以现状为基准，在满足中国国家标准的前提下，住宅建筑节能可达31.5%，在满足重庆地方标准和英国标准的前提下，住宅建筑节能可达45.0%和53.4%。公共建筑节能潜力分别为62.8%、67.4%和75.9%。进行参数敏感性分析。该分析能够为住宅和公共建筑的节能实施重点提供建议。还讨论了改进建筑能源标准及其实施的迹象。
Hot Summer and Cold Winter (HSCW) region plays an important role in China's building energy conservation task due to its high consumption in recent years for both climate and social reasons. National and local building energy standards according to which the buildings are built and operated can affect the building energy consumption to a great extent. This study investigated the energy saving potential in Hot Summer and Cold Winter Zone under different level of energy efficiency standards (China local, China national, and UK standard). Chongqing was taken as an example, and the commercial energy simulation tool eQuest was applied to analyze the building end-use energy. With the existing situation as a baseline, the building energy saving for residential section could achieve 31.5% if the Chinese national standard were satisfied, and the value would further increase to 45.0% and 53.4% when the Chongqing local and UK standard were met. For public buildings, the corresponding energy saving potentials were 62.8%, 67.4% and 75.9%. Parameter sensitivity analysis was conducted. The analysis was able to provide suggestions on energy saving implementation priorities for residential and public buildings. Indications to improve building energy standards and their implementation were also discussed.
