Abstract

This study provides a review of the current state of knowledge, gaps, and potential value in research on the prevalence of faults in commercial buildings. Two separate efforts were made in this study: (1) we performed a literature review to determine the extent of currently available fault prevalence data for heating, ventilation, and air-conditioning (HVAC) systems, and (2) we conducted dozens of interviews with subject matter experts and stakeholders to determine the HVAC fault data that would be of greatest value. Through the literature review and interviews, we discovered unmet needs for empirical data on the prevalence of faults at the desired level of granularity, consistency, and scale; this lack of data leads us to recommend future work studying commercial buildings’ HVAC fault prevalence, with robust fault taxonomy and a variety of meaningful fault prevalence metrics.

摘要

这项研究提供了对商业建筑物中的故障发生率的研究的知识，差距和潜在价值的当前状态的审查。在这项研究中，我们进行了两项单独的努力：（1）我们进行了文献综述，以确定供暖，通风和空调（HVAC）系统的当前可用故障率数据的范围，以及（2）我们进行了数十次访谈与主题专家和利益相关者一起确定最有价值的HVAC故障数据。通过文献综述和访谈，我们发现在期望的粒度，一致性和规模级别上，关于故障普遍性的经验数据的需求尚未得到满足。由于缺乏数据，我们建议对未来的研究工作进行研究，以研究商业建筑的HVAC故障发生率，
