西安地区住宅建筑采暖能耗分级研究

Heating Energy Consumption Hierarchy for Residential Buildings in Xi'an

当前我国居住建筑节能设计尚未形成比较明确的分级体系,势必造成人均能耗不公平现象,即人均居住面积较大的别墅的人均能耗要远大于人均居住面积较小的经济适用房的人均能耗。为改观上述现象、缩小居住建筑人均能耗之间的差异,探讨了居住建筑分级体系系统的建立,选取了西安地区3种典型居住建筑:别墅建筑、普通高层住宅、城市经济适用房。根据建筑建造信息及调研结果分别对3栋不同形式的建筑冬季采暖的人均能耗指标进行计算,最终通过技术手段对人均能耗较大的别墅在设计阶段给出必要的热工指标约束,对人均能耗较小的经济适用房在建成后提出政府补贴政策,以求在某种程度上改善人均能耗不公平的现象。

For the study of staging hierarchy is relative absence in energy conservation of residential buildings in current China, and it must result energy consumption unfairness, i.e. as the living area of villa is bigger, and its per-capita energy consumption will be greater than the urban affordable housings’. To e-liminate the energy wasting and reduce per-capita energy consumption differences, the system of staging hierarchy in residential buildings is established. Three typical residential buildings with different types were chosen as fellow： villa, high-rise flats and urban affordable housings. And the per-capita heat con-sumption index of those residential buildings in heating season is calculated according to BIM （the building information model） and research report, and then summing up with the necessary restraint of thermo-tech-nical indexes by technological method before initial design phase of villa, also making suggestions of gov-ernment subsidy policy for affordable housings after finish, so that the per-capita energy consumption un-fairness will be improved to a certain extent.
