本研究旨在确定当今市场上可操作窗户的低温空气泄漏程度，以及这对房屋能耗的影响。在供暖季节，由于热效应和压力效应，窗户的泄漏特性将发生变化。在两个实验室，在35扇窗户上进行了低至-30°C的空气泄漏测试，足以得出一些关于性能的一般结论。大多数窗户在正常温度下达到或超过加拿大窗户标准的最高漏风性能水平，许多窗户即使在测试的最低温度下也表现良好。低温下泄漏增加的原因不仅仅是框架材料的设计；垂直滑块（包括倾斜）在所有条件下表现最差。 数据用于量化对房屋年度能源性能的影响。加拿大标准协会（CSA）的房屋窗户性能指标CSA能源评级（ER）编号（CSA 1993）针对室外气候下的可变空气渗透情况进行了评估。结果令人鼓舞；对于大多数窗户，只要在正常温度下泄漏量不太大，对额定值的影响可以忽略不计。对于其他人来说，他们学到了在极端温度下可以用来改善产品性能的材料和设计。单位:SICitation:研讨会，ASHRAE交易，1998年，第104卷，pt。1A，旧金山

This study was initiated to determine the extent of cold temperature air leakage from operable windows available in today's marketplace and the impact that this has on the energy consumption of a house. During the heating season, changes in the window's leakage characteristics, as a result of thermal and pressure effects, were to be included. At two laboratories, air-leakage tests down to -30°C were performed on 35 windows, enough to reach some general conclusions about performance. The majority of windows met or exceeded the highest levels of air leakage performance of Canadian window standards at normal temperatures, and many did very well even at the lowest temperatures tested. Increased leakage at cold temperatures was attributed to design more than frame material; vertical sliders (including tilt-in) exhibited the worst performance under all conditions. Data were used to quantify the impact on the annual energy performance of a house. The Canadian Standards Association's (CSA) window performance indicator for houses, the CSA Energy Rating (ER) number (CSA 1993), was evaluated for the case of variable air infiltration with outdoor climate. Results were encouraging; for the majority of windows the impact on the rating was negligible, as long as leakage was not excessive at normal temperatures. For others, lessons were learned about materials and designs that could be used to improve product performance at extreme temperatures.Units: SI
