ANSI/ASHRAE/IES标准90.1要求在气候带3至8的建筑中安装前厅，基于建筑能耗模拟，并采用一种新的气流和能耗模拟方法避免一系列假设。人们认为，空气幕可以代替前厅，减少建筑物入口的渗透和相关能量损失。因此，本研究提出了一种估算美国能源部16个国家的两栋参考建筑的前厅和气帘门节能的方法。 根据国家加权平均节能和不同贡献参数的敏感性研究，对美国气候区的位置进行评估。引文:ASHRAE Transactions，第124卷，pt。2009年12月2日，休斯顿

ANSI/ASHRAE/IES Standard 90.1 requires vestibules to be installed in buildings in climate zones 3 through 8 based on building energy simulations with a series of assumptions which can be avoided using a new method of airflow and energy simulations. Instead of vestibules, it is believed that air curtains can also reduce infiltration and the associated energy loss through building entrances. Therefore, this study proposes a method to estimate energy savings from vestibule and air-curtain doors for two U.S. Department of Energy reference buildings in 16 U.S. climate zone locations in terms of national weighted average energy savings and a sensitivity study of different contributing parameters.
