Abstract
Providing a healthy and comfortable indoor environment is essential as people spend the majority of their time indoors. While indoor environmental quality includes different aspects, thermal comfort and indoor air quality are two of the most important. Researchers have studied the indoor environmental quality of different types of buildings such as offices or residential buildings, but there has been less focus on sports facilities. The literature also shows that the objective measurements of thermal comfort and indoor air quality usually require costly devices and workforce, and do not provide a long-term picture as they are based on snapshot measurements.
This research aimed to address these gaps through a post-occupancy evaluation of thermal comfort and indoor air quality of a sports facility: The Active Living Centre, certified as a Leadership in Energy and Environmental Design Silver building and located at the Fort Garry campus of the University of Manitoba. The facility’s automation systems were used as the data source for objective measurements. Temperature, relative humidity, and carbon dioxide data were extracted from enteliWEB, the studied facility’s automation systems application, for the Summer (June and July) and Fall (September and October) 2019. In addition, users of the facility’s main fitness area (gym users) and staff were surveyed in July and October to compare their perceptions with actual conditions. A total of 104 and 49 gym users participated in the survey in the Summer and Fall, respectively. Also, eight and seven staff members took part in the survey in the Summer and Fall, respectively.
Although indoor air temperatures were higher in the Fall, gym users were more dissatisfied with the temperature in the Summer. As the mean relative humidity level in the Summer was nearly 14% higher than its Fall value, the higher dissatisfaction rate with temperature in the Summer may have been due to higher relative humidity levels in that season. The majority of users were satisfied with indoor air quality in both seasons. Mean CO2 levels were 510 ppm and 521 ppm in the Summer and Fall, respectively. The facility, as a green building, was more thermally comfortable in the Fall.
