这是描述ASHRAE 1544研究项目结果的一系列技术论文中的第一篇。由于ASHRAE对图表数量和论文总长度的限制，不可能在一篇论文中呈现研究项目的结果。预计最终会有6到10篇技术论文描述研究结果。其中前三篇论文已提交同时发表。酒店的热水使用及其相关的能源使用非常重要。然而，关于酒店的信息很热- 到目前为止，用水模式一直受到限制，导致大多数酒店热水系统的设计使用了非常古老（45至80年）的热水使用数据，这些数据早于节水节能装置和器具的引入。鉴于这一事实，ASHRAE资助了1544研究项目“建立商业热水使用酒店的基准水平和模式”，以开发一种其他人可以复制的监测方法，从更多酒店收集热水使用数据，并从至少两家酒店获取更新的热水使用信息。 第一篇论文描述了用于定位和征集参与酒店的技术，测试酒店的详细信息，以及现场测试工作中使用的仪器、数据收集方法和设备。与本文同时发布的其他技术论文描述了从两个测试酒店收集的数据，讨论了相似性和差异。这些额外的论文详细描述了观测到的热水使用时间多样性。随后将于日后发布的技术文件描述了一个程序，该程序用于标准化结果，以便将其应用于不同规模和不同类型的酒店- 用水设备和固定装置。该规范化程序导致开发了一种新的酒店热水系统尺寸确定程序，并附有设计示例，该程序也在随后发布的技术文件中进行了描述。所有这些信息都包含在项目最终报告中（Hiller and Johnson 2015）。引文:2016年冬季会议，佛罗里达州奥兰多，2016年交易，第122卷第。1.

This is the first in a series of technical papers written todescribe results of ASHRAE Research Project 1544. Becauseof ASHRAE's limitations on the number of figures and tablesand overall paper length, it is not possible to present resultsfromthe research project inasingle paper. It is anticipated thatbetween 6 and 10 technical papers will ultimately be writtendescribing findings from the research. The first three of thesepapers have been submitted for simultaneous publication.Hot-water use in hotels and its associated energy use issignificant. However, information on hotel hot-water usepatterns has been limited until now, resulting in most hotel hot watersystems being designed using extremely old (45 to 80years old) hot-water use data that predate the introduction ofwater- and energy-efficient fixtures and appliances. In recognitionof this fact, ASHRAE funded Research Project 1544“Establishing Benchmark Levels and Patterns of CommercialHot-Water Use—Hotels” to both develop a monitoring methodologythat could be duplicated by others to collect hot-wateruse data from a larger number of hotels and to obtain updatedhot-water use information from at least two hotels.This first paper describes the technique used to locate andsolicit participating hotels, details about the hotels tested, andthe instrumentation, data collection approach, and equipmentused in the field test effort. Additional technical papers beingreleased simultaneously with this paper describe datacollected from two hotels tested, discussing similarities anddifferences. Those additional papers describe in detail theobserved hot-water use time diversity. Subsequent technicalpapers to be published at a later date describe a procedure thatwas developed for normalizing the results so they can beapplied to hotels of different sizes and with different types ofhot-water-using equipment and fixtures. This normalizationprocedure led to the development of a new hotel hot-watersystem sizing procedure, complete with design examples,which is also described in subsequent technical papers beingreleased at a later date. All of this information is included inthe project final report (Hiller and Johnson 2015).
