英国居住建筑节能实践及其启示

Energy Conservation Practices of UK's Residential Buildings and its Inspiration

本文在介绍英国全年气候特点、居住建筑特点以及总结居住建筑节能实践情况的基础上,分析了英国居住建筑节能实践所采用的协调建筑节能与建筑立面维护、建筑节能与室内舒适度以及建筑节能与建筑防潮的相互关系的方法。分析结果表明,国内民用建筑的节能实践可以借鉴英国民用建筑节能实践的相关经验,以解决如下几方面问题:1)建筑节能实践活动对建筑外立面、建筑结构的影响;2)室内舒适度和节能效果的取舍问题,一味地强调节能效果而"牺牲"室内热舒适度;3)建筑物外围护结构的保温措施导致建筑物外表面温度急剧降低,在空气相对湿度较大地区会造成建筑外表面结露。

Based on the UK＇s annual weather characteristics,its residential building characteristics and energy efficient practices,the methods to balance the relationships between building energy efficiency and building facade maintenance,building energy efficiency and indoor comfort degree and building energy efficiency and damp proof are analyzed. The analysis indicates that the related experiences of the UK residential building energy-saving practices can be used as reference in the building energy conservation practices in China to solve the following questions： 1） effect of building energy conservation practice on building faade and structure. 2） coordination problem of indoor comfort and energy saving effect. Put the energy saving front of the indoor thermal comfort. 3）the building envelope heat preservation measures lead to sharp decrease of the building outside surface temperature,which will cause condensation building outside surface in area of relative larger air humidity.
