苏北地区居住建筑外窗现状调查及节能外窗设计技术研究

外窗是居住建筑室内外空间变换的重要媒介,同时也是建筑节能的一个关键环节。通过对苏北地区建筑外窗市场及既有居住建筑外窗应用情况实地调查,分析该地区外窗的基本物理、热工性能参数及存在的问题,总结新型节能外窗的关键设计技术。结合不同地区建筑文化、气候等特征优化设计并推广应用节能外窗,才能实现降低建筑能耗,减少温室气体排放的目的。

FIELD INVESTIGATION OF RESIDENTIAL BUILDING'S EXTERIOR WINDOWS AND STUDY OF DESIGN TECHNIQUES FOR ENERGY-SAVING WINDOW IN NORTH JIANGSU PROVINCE

Exterior window is an important room transformation medium for residential building between indoor and outdoor environment,and it is also the key link for building energy-efficiency.Based on the field investigation and statistics data of building exterior windows in local market and existing residential buildings,window's problems and basic physical and thermal properties were analyzed.Then,key design techniques for new kind energy-saving exterior window were summarized.The paper pointed out it would achieved the purpose of lowing building energy-consumption and reducing green house gas emission,only in popularizing the energy-saving window optimally designed based on local architecture culture and climate characteristics.
