能源改造为减少现有建筑的碳足迹提供了一个具有经济吸引力的解决方案。然而，在改造过程中，室内环境质量和乘员舒适性往往被忽视。本文介绍了加拿大多伦多1965年至1975年间建造的几栋多单元住宅楼的改造前监测结果。在目前正在进行能源改造的七栋社会住房建筑的70多个单元中测量了温度、相对湿度和平均辐射温度。使用ASHRAE标准55中概述的图形舒适区和分析方法估计乘员热舒适性- 2013年。非空调期间的内部蒸汽压过剩用于评估套房内的水分过剩。一个主要的发现是，50%以上的时间里，这些设备都不舒服，过热是不舒服的主要原因。建筑物内的位置（例如，上层与下层）和建筑物特有的影响几乎没有显示出影响，尽管季节性相关性较弱，夏季过热程度更高。这些发现与项目早期进行的住户调查一致。没有一致的证据表明水分过多，尽管这可能是由于观察到的机组过热和监控设备的位置造成的。 研究结果被用于指导能源改造设计过程，目前正在进行监测，以确定改造如何影响这些建筑的职业舒适性。引用:2016年年度会议，密苏里州圣路易斯，会议论文

Energy retrofits provide an economically attractive solution to reduce the carbon footprint of existing buildings. However, indoor environmental quality andoccupant comfort are often overlooked in the retrofit process. In this paper, we present the results of pre-retrofit monitoring of several multi-unit residentialbuildings built between 1965 and 1975 in Toronto, Canada. The temperature, relative humidity and mean radiant temperature were measured in over70 units across seven social housing buildings currently undergoing an energy retrofit process. Occupant thermal comfort was estimated using both theGraphic Comfort Zone and Analytical methods outlined in ASHRAE Standard 55-2013. Internal vapor pressure excess during non-air conditioningperiods was used to assess excess moisture in the suites. A major finding was that the units were uncomfortable over 50% of the time, with overheatingbeing the main cause of discomfort. Location within a building (e.g., upper vs. lower floors) and building-specific effects showed little impact, although therewas a weak seasonal correlation with more overheating in the summer. These findings are consistent with an occupant survey taken early in the project.There was no consistent evidence of excess moisture, although this may be due to the observed overheating in the units and the location of the monitoringequipment. The results were used to inform the energy retrofit design process and are currently being monitored to ascertain how the retrofits affect occupantcomfort in these buildings.
