In the last decades, the importance of indoor environmental quality and perceived comfort in the built environment has been raised both in the scientific research field and in everyday life practice. Particularly, it has been proved that enhancing quality and comfort in the built environment allows for the improvement of, among other aspects, health, productivity and well-being. Furthermore, supporting optimal environmental conditions also allows for the implementation of building automation and control systems (BACS) and strategies for the reduction of energy consumptions. To account for the needs related to several occupants and to the built environment itself, it is fundamental to study Indoor Environmental Quality (IEQ) and Indoor Environmental Comfort (IEC) considering all the physical domains of the built environment, i.e., acoustic, thermal, visual and of air quality.
