1总则

1.0.1为贯彻国家和西藏自治区关于建筑节能的政策、法规和标准，提高建筑节

能设计水平，加强民用建筑节能工程的管理，保证工程质量，制定本标准。

1.0.2本标准适用于西藏自治区新建、改建、扩建以及既有建筑节能改造的民用

建筑的节能设计、施工和验收。以下情况的建筑应按下列原则确定本标准对其的

适用条件：

1集体宿舍、托儿所、幼儿园、公寓按居住建筑进行节能设计；

2使用年限在5年以下的临时建筑可不强制执行本标准；

3工厂区内独立的办公建筑、生活配套建筑等应执行本标准公共建筑的规定；

4附建在工业厂房的办公用房等非工业部分，其面积占整个建筑面积的比例

大于等于30％，或面积大于等于1000m2，非工业部分应执行本标准公共建筑的

规定；

5公共建筑中的居住部分，其面积占整个建筑面积的比例不小于10%，且面

积不小于1000㎡，居住部分应执行本标准居住建筑的规定，公共部分应执行本

标准公共建筑的规定；

6用于企业研发和软件开发等的建筑物应执行本标准公共建筑的规定；

9新建民用建筑不执行本标准第9章的规定。

1.0.3民用建筑节能应遵循因地制宜、被动优先、主动优化的原则，选择适宜的技

术和材料，改善围护结构保温隔热性能，提高建筑设备及系统的能源利用效率，

充分利用可再生能源，降低建筑能耗。
