空气将通过密封不好的建筑围护结构泄漏。这种空气泄漏会让湿气、冷风和不必要的噪音进入住宅，从而降低住宅的舒适度，而空气泄漏可能占典型住宅供暖和制冷所需能量的40%。在一个典型的住宅中，近一英里的外部接缝可能会泄漏空气，因此知道哪些接缝泄漏的空气量最大，就可以最有策略地放置密封剂。这篇分为两部分的论文描述了一项广泛的调查，以量化住宅结构中各种类型的接缝和开口的泄漏特性。总之，通过使用风扇增压的实验室和实际室内测量，对17个不同的接头/开口进行了表征。第1部分介绍了与单个接头/开口漏气相关的方法和结果。 第2部分将这些单独的结果应用于整个房屋，包括检查墙体空腔中的接缝泄漏。出席2013年12月第十二届全建筑外围护结构热工性能研讨会简介:全建筑外围护结构热工性能第十二届

Air will leak through a building envelope that is not well sealed. This leakage of air decreases the comfort of a residenceby allowing moisture, cold drafts, and unwanted noise to enter, and air leakage can account for up to 40% of the energyused for heating and cooling in a typical residence. With nearly a mile of exterior joints that can leak air in a typical residence,knowing which joints leak the largest quantity of air allows for the most strategic placement of sealant. This twopartpaper describes an extensive investigation to quantify the leakage characteristics of various types of joints and openingsin a residential structure. All-in-all, 17 different joints/openings were characterized through both laboratory and real-housemeasurements using fan pressurization. Part 1 presents the methods and results associated with the air leakage of the individualjoints/openings. Part 2 adapts these individual results to the whole house, including an examination of the joint leakageinterdependence in the wall cavity.Presented at Thermal Performance of Exterior Envelopes of Whole Buildings XII, December 2013
