“…Thus, Fanger proposed an experiment on 1296 individuals who, after remaining in a thermal chamber, had to give an answer regarding the thermal environment on a seven-point sensation scale, defined by ASHRAE (from -3 cold to +3 hot). Based on this survey, Fanger proposed the equation [93] PMV = (0.303 e −0.036M + 0.028) S (15) where M is the metabolic rate and S is the heat storage. PPD index is defined as the predicted percentage of dissatisfied with regard to a certain environment, considering dissatisfied a person who, subjected to a certain thermal environment, express a rating of +3, +2, −2, or −3 on the thermal sensation scale.…”

“…The first provides a value of the operative temperature dependent on the relative air velocity by means of a coefficient A, t o = A t a + (1 − A) t r (19) where A = 0.5 when the relative air velocity is lower than 0. The humidity index (humidex) has been used to assess thermal comfort in a swimming pool [15]. This index is a dimensionless number which allows the evaluation of air temperature and humidity on an average person.…”

“…In moderate environments, defined as spaces in which it is possible to reach the condition of thermal well-being, only few studies have been carried out. These studies were focused on the monitoring the thermal conditions according to thermal comfort indices [14,15], on the interventions to improve thermal comfort [16,17], on the comparison between objective and subjective measurements [18,19], on the assessment of thermal comfort to balance energy use [16,20] and on the association between thermal comfort and physiological responses during exercise [21,22]. However, there was no standardization in the measurement methodologies or in the models that were used to predict thermal sensation in sport facilities.…”

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.

“…While most of the available simulators are focused on the performance of electrical and thermal networks, TRNSYS can similarly well be used to model other dynamic systems such as traffic flow, or even biological processes [57,58]. Studies using TRNSYS are reported in the literature as comparing cooling strategies for an office in different European climates [59], thermal comfort in an indoor swimming pool [60], or operating performance in cooling mode of a nearly zero energy building in China [61].…”

In the present work, we analyze the influence of the designer’s choice of values for the human metabolic index (met) and insulation by clothing (clo) that can be selected within the ISO 7730 for the calculation of the energy demand of buildings. To this aim, we first numerically modeled, using TRNSYS, two buildings in different countries and climatologies. Then, we consistently validated our simulations by predicting indoor temperatures and comparing them with measured data. After that, the energy demand of both buildings was obtained. Subsequently, the variability of the set-point temperature concerning the choice of clo and met, within limits prescribed in ISO 7730, was analyzed using a Monte Carlo method. This variability of the interior comfort conditions has been finally used in the numerical model previously validated, to calculate the changes in the energy demand of the two buildings. Therefore, this work demonstrated that the diversity of possibilities offered by ISO 7730 for the choice of clo and met results, depending on the values chosen by the designer, in significant differences in indoor comfort conditions, leading to non-negligible changes in the calculations of energy consumption, especially in the case of big buildings.

In an indoor kitchen environment, proper installation of supplying air system is essential for maintaining optimal human thermal comfort level. Current thermal comfort investigation has been accomplished during "various cooking periods (breakfast, lunch, snacks, dinner)" inside the air-conditioned kitchen environment of railway pantry car in India. The study goals to improve thermal comfort inside the pantry kitchen by implementing proper installation of the supply air system. A field experiment and computational fluid dynamics approach has been carried out during the summer season. Also, standard effective temperature (SET) index was utilized to determine the thermal comfort status. Three proposed design modified cases of pantry cars (based on supplying air system concepts) have been executed followed by validation and comparison with the existing case model. Results revealed modified Case III as a better design concept (indicating better air supply circulation and temperature decrease at the desired location) compared to the existing and other two proposed cases. Simultaneously, the SET index range was 26.5-28.6°C; indicating "comfortable thermal sensation throughout the cooking period." This study's outcomes suggest improvements in thermal comfort and energy savings of "airconditioned" pantry car kitchens in "Indian Railways" that could be referred directly.
