我国建筑节能中的若干问题分析
Some issues in building energy efficiency in China
摘要：
以德国节能建筑法规和能效标识为参考，对我国现有建筑节能标准及其内容进行了分析，提出了一些需要完善和改进的意见。建筑节能必须用全年的时间段来分析，才能得出完整、正确的结论；我国建筑能耗的考核统计应全面、规范，除了应有建筑供暖空调能耗限制，也应对建筑的用电、生活热水的能耗和设备、系统效率纳入考核；我国的建筑除了应制定出基本的强制性标准外，还应制定出中、高级的不同等级的建筑节能标准；我国既有建筑的节能工作应加强建筑的气密性、热桥、自然通风与热回收等环节。
Abstract：
Referring to the German building energy efficiency laws and energy labelling, analyses the current Chinese standard for building energy efficiency and its content. Puts forward some ideas to perfect and improve the standard. Building energy efficiency should be analysed in view of the whole year period in order to get a complete and correct conclusion. The assessment and statistics of building energy consumption should be performed in a comprehensive and normative mode i.e. in addition to the building heating and cooling energy consumption, the electricity consumption, the energy consumption for domestic hot water supply and the system efficiency of buildings should also be assessed. Besides establishing basic mandatory standard for building energy efficiency, it is needed to lay down standards for medium to high classes with different levels of building energy efficiency in China. Such links as air tightness, thermal bridge, natural ventilation and heat recovery should be strengthened for the energy efficiency improvement in current buildings.
