我国严寒地区公共建筑节能降耗水平评价指标体系研究

Study on the Public Building Energy Saving Level Evaluation Index System of China’s Cold Region

摘要: 我国严寒地区冬季采暖期长、公共建筑能耗水平较高，节能降耗水平评价成为促进区域建筑节能减排的关键因素。本文通过结合国内外先进经验，遵循评价指标体系构建原则，运用层次分析法、模糊隶属度函数等方法，构建了严寒地区公共建筑节能降耗水平评价指标体系，并以吉林省为实例进行了评价和分析。研究结果显示，吉林省公共建筑节能降耗水平为良，同时存在诸如采暖能耗高、可再生能源利用程度低、节能改造有待进一步提高等问题，指标体系切实可用。研究结果对促进严寒地区公共建筑节能减排具有一定的现实意义。

Abstract: Because the heating period is long in the severe cold area of China, and the public buildings’ energy consumption is in a high level, evaluating of energy saving becomes the key factor in promoting public building’s energy saving. In this paper, analytic hierarchy process and fuzzy membership function method are used to construct a public building energy saving evaluation index system for cold region by combining the experience of building energy saving at home and abroad and constructing principles for evaluation index system. Jilin Province is chosen as an example to be evaluated and analyzed, according to the evaluation index system. The study results show that the energy saving level of public building in JilinProvinceis good. Meanwhile, there are some problems, such as high heating energy consumption, low utilization of renewable energy and low level of energy saving. Therefore, the evaluation index system is practicable. In a word, the study results are of practical significance to promote the urban public building energy saving in cold regions.
