Abstract

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.

Highlights

  • In recent years, ensuring comfort in indoor environments has become a real challenge involving different disciplines

  • Thermal environments can be seen as a combination of physical, physiological, and psychological factors, and the interaction between these three aspects determines the thermal sensation of humans

  • In spaces in which physical activity is carried out, the physiological component is relevant, as the metabolic rate is high and the body produces a consistent amount of heat, which must be dispersed in the environment

Summary

Introduction

In recent years, ensuring comfort in indoor environments has become a real challenge involving different disciplines. Thermal comfort has been often studied in relation to the characteristic of the envelope and of the internal structures [9], as the thermal behavior of the building can largely influence the environmental conditions indoors, which has an impact on the comfort and performance of people In sport facilities, these four aspects have been studied in order to improve the comfort and the performance of the athletes. This paper lays the groundwork for future research on the determination of indoor thermal comfort in sport facilities located in moderate environments, as in these spaces thermal conditions have a fundamental role in the performance and in the health of the athletes
