热水使用占美国住宅能耗的第二大部分，但人们对此知之甚少。ASHRAE研究开发了一种成本效益高、不引人注目且准确的协议，用于测量和描述住宅热水使用情况，称为“基于温度的事件推断”方法。该方法直接测量最终使用管道温度的变化，并结合热水箱的测量流量，以分配生活热水。该报告描述了将该方法应用于五个住宅的方法、程序和结果，并为收集更广泛的数据奠定了基础。 2002年年度会议上提交的两篇技术论文也可供查阅（第108（2）卷#4595，HI-02-8-1）。1172-RP《按最终用途计量住宅热水》（标准协议的制定）由TC 6.6《工业用水供暖》赞助。主要研究者是内布拉斯加大学林肯分校的Dale Tiller。

Hot water use accounts for the second largest portion of residential energy consumption in the U.S. but it is poorly understood. ASHRAE research developed a cost effective, unobtrusive, and accurate protocol for measuring and characterizing residential hot water use called the “temperature-based event inference” method. This method directly measures the change in end use pipe temperature in conjunction with the measured flow at the hot water tank to allocate domestic hot water draws. The report describes the methods, procedures, and results of applying the method to five residences and sets the groundwork for collecting more extensive data. Two technical papers presented at the 2002 Annual Meeting are also available (Vol. 108(2) #4595, HI-02-8-1). 1172-RP, Metering Residential Hot Water by End Use (Development of a Standard Protocol), was sponsored by TC 6.6, Service Water Heating. The principle investigator was Dale Tiller of the University of Nebraska - Lincoln.
