寒冷地区高校既有建筑节能技术体系研究

当前,降低建筑能耗的投资约为降低工业能耗投资的5倍,因此建筑节能的能效水平及技术的经济性就尤为重要。基于我国为数众多的各类高校已成为国内重要的能源消耗大户,以寒冷地区高校既有建筑为研究对象,阐述通过能耗调查和测试数据,进行建筑能耗模拟分析,可找到既有建筑能耗的关键问题,并确立节能改造原则,制定相应的节能技术体系,此为解决高校既有建筑节能问题的关键。对技术的应用则应针对不同的既有建筑能耗特点和改造资金投入状况,进行灵活的技术组合和应用,构成不同层次的节能技术群,使得改造得以真正地实施。

RESEARCH OF ENERGY EFFICIENCY TECHNOLOGY SYSTEM OF UNIVERSITY EXISTING BUILDING IN COLD CLIMATE ZONE

At present,investment to reduce building energy consumption is about 5 times to reduce industrial energy investment,so the energy efficiency standards and technology economy of building is particularly important.Due to the fact that large number of universities in our country has become an important energy guzzler,using university existing buildings in cold area as research object,it was elaborated that by energy consumption surveys and testing data,simulation and analysis of existing building energy consumption,the key issues of existing building energy consumption could be found;the principle and technology system of energy efficiency retrofitting were established,which was the key to solve the problem of energy efficiency with university existing buildings.The use of technology should be on different characteristics of the existing buildings energy consumption and funds of retrofitting;flexible combination of technologies and applications was done;different levels of energy efficiency technology group were formed,which made the retrofitting be implemented truly.
