摘要本文研究了用现代双层玻璃和通风密封窗取代旧窗户对家庭背景空气渗透的影响，包括有和没有可控通风（如滴流式空调器）。估计的方法，在渗透率的变化产生这样的窗口更换进行审查。已经开发了一个简单的模型，使用实验室测量的窗口透气性，预测减少渗透，可以预期当给定数量的窗户被替换在住宅。该模型的有效性进行了测试，从一个房子的数据之前和之后更换窗户。该论文调查了英国国内建筑物更换窗户（部分受到英格兰和威尔士建筑法规L部分的刺激）可能对国内建筑物充分通风的影响。本文得出的结论是，更换旧窗户在英国的住宅的显着比例可以降低通风水平低于建议的水平，除非可控的背景通风安装在同一时间作为新的窗口。
Abstract This paper examines the impact on domestic background air infiltration of replacing ‗old windows‘ with modern double-glazed and draught sealed windows, both with and without controllable ventilation (e.g. trickle ventilators). Methods of estimating the change in infiltration rate produced by such a window replacement are reviewed. A simple model has been developed which, using laboratory measurements of window air permeability, predicts the reduction in infiltration that can be expected when a given number of windows are replaced in a dwelling. The validity of the model has been tested using data from a house both before and after replacing the windows. The paper investigates the impact that replacing windows in the UK domestic building stock (partly stimulated by Part L of the Building Regulations in England and Wales) is likely to have on the adequate provision of ventilation in the domestic stock. The paper concludes that replacing old windows in a significant proportion of UK dwellings can reduce ventilation levels below recommended levels unless controllable background ventilation is installed at the same time as new windows.
