“…13,14 In addition to these pollutants, also for example, ultrafine particles (UFPs), volatile organic compounds (VOCs), aldehydes (eg, formaldehyde (HCHO)), ozone (O 3 ), and bioparticles (fungi and bacteria)) could be cause for health effects in some sports facilities. Besides, important comfort parameters-temperature (T) and relative humidity (RH)-may affect for example material emissions [15][16][17] and occupant's perception of the indoor air quality (IAQ) 18 and should be taken into account when evaluating exposure issues in sports facilities.…”

Physical activity is one of the most basic human functions and a significant basis of health. The World Health Organization (WHO) 1 recommends that adults, including older adults, undertake at least 2.5 hours of moderately intense aerobic activity per week. With an increasing number of sports enthusiasts worldwide, the number of indoor sports facilities and the number of workers in those facilities have also increased dramatically in the past decades. However, unlike residential areas and other types of public spaces, such as schools and offices, there is relatively little published research about air quality and exposure to different pollutants in various indoor sports facilities, 2,3 where a growing number of people exercise, work full or part time, or attend athletic events. 4,5 Although many studies of athletes' exposure to ambient air contaminants have been published, 6-10 little work is known about the exposure to air pollutants in different indoor sports facilities. Available publications have been focused on ice arenas, with the most investigated pollutants being carbon monoxide (CO), nitrogen dioxide (NO 2), and particulate matter (PM 10 and PM 2.5 , referring to

“…In the building sciences, including the areas of indoor air quality [13,19,[24][25][26], dampness and mold [27], thermal comfort [5,[28][29][30][31][32], acoustics [6,33], green buildings [4,34,35], lighting [36,37], and indoor environmental quality (IEQ) [9,[38][39][40][41][42][43][44][45][46][47][48], chamber and field studies are the predominant experimental approaches for conducting human subject research relating measures of physical conditions to human outcomes. Typically, chambers are the dimensions of a small to medium-sized office and are equipped with building systems (e.g., ventilation system, lighting, sound masking) capable of maintaining stable experimental conditions.…”

The living lab approach to building science research provides the ability to accurately monitor occupants and their environment and use the resulting data to evaluate the impact that various components of the built environment have on human comfort, health, and well-being. A hypothesized benefit of the living lab approach is the ability to simulate the real indoor environment in an experimentally controlled setting over relatively long periods of time, overcoming a significant hurdle encountered in many chamber-type experimental designs that rarely reflect typical indoor environments. Here, we present indoor environmental quality measurements from a network of sensors as well as building system design and operational data demonstrating the ability of a living lab to realistically simulate a wide range of environmental conditions in an office setting by varying air temperature, lighting, façade control, and sound masking in a series of three human subject experiments. The temporal variability of thermal and lighting conditions was assessed on an hourly basis and demonstrated the significant impact of façade design and control on desk-level measurements of both factors. Additional factors, such as desk layout and building system design (e.g., luminaires, speaker system), also contributed significantly to spatial variability in air temperature, lighting, and sound masking exposures, and this variability was reduced in latter experiments by optimizing desk layout and building system design. While ecologically valid experimental conditions are possible with a living lab, a compromise between realism and consistency in participant experience must often be found by, for example, using an atypical desk layout to reduce spatial variability in natural light exposure. Based on the experiences from these three studies, experimental design and environmental monitoring considerations for future office-based living lab experiments are explored.

“…Even if this aspect is often underestimated, the perception of a thermal environment is strongly related to the psychological conditions. For this reason, most of the researchers in their studies assessed the thermal sensation of the athletes with the use of questionnaires [18,19,21,89]. In particular, with regard to the subjective perception of the thermal environment, the research of Revel and Arnesano [18] compared the predictive models to the subjective responses in order to determine the impact of high metabolic rates and sport garments on systematic errors in the prediction of Fanger's indices.…”

In previous years, providing comfort in indoor environments has become a major question for researchers. Thus, indoor environmental quality (IEQ)—concerning the aspects of air quality, thermal comfort, visual and acoustical quality—assumed a crucial role. Considering sport facilities, the evaluation of the thermal environment is one of the main issues that should be faced, as it may interfere with athletes’ performance and health. Thus, the necessity of a review comprehending the existing knowledge regarding the evaluation of the thermal environment and its application to sport facilities becomes increasingly relevant. This paper has the purpose to consolidate the aspects related to thermal comfort and their application to sport practice, through a deep study concerning the engineering, physiological, and psychological approaches to thermal comfort, a review of the main standards on the topic and an analysis of the methodologies and the models used by researchers to determine the thermal sensation of sport facilities’ occupants. Therefore, this review provides the basis for future research on the determination of thermal comfort in indoor sport facilities located in moderate environments.
