Buildings are constructed and operated to satisfy human needs improve quality of life. Good indoor air (IAQ) thermal comfort prerequisites for health well-being. For their provision, buildings often rely on heating, ventilation, conditioning (HVAC) systems, which may lead higher energy consumption. This directly impacts efficiency goals the linked climate change considerations. The balance between use, optimum IAQ calls scientifically solid well-established limit values exposures experienced by building occupants in spaces, including homes, schools, offices. present paper aims appraise selected pollutants reported scientific literature, how they handled international national guidelines standards. include carbon dioxide (CO2), formaldehyde (CH2O), particulate matter (PM), nitrogen (NO2), monoxide (CO), radon (Rn). Furthermore, acknowledging particularly strong impact use from HVAC, temperature (T), relative humidity (RH) also included, as relate both possibilities avoid moisture related problems, such mould growth proliferation house dust mites.

Previous studies investigating the relationship between indoor environmental quality and worker productivity have suggested that thermal environment has a significant impact on productivity. Some of these reported was less than optimal when thermally neutral comfortable (i.e., PMV = 0.0). However, analyses in those did not consider personal attributes, data hierarchy resulting from multiple responses survey participants also considered. Thus, there is no consensus temperature for In this study, measurement questionnaire were conducted to assess slightly cool while considering attributes workers. The with air conditioning set 0.0 −0.5 2 weeks during late spring Tokyo, Japan. results multilevel analysis revealed sensation differed according gender. Men most productive it cooler (thermal −0.61, "−1. cool" "0. neutral"), women warmer 0.23, neutral" "1. warm"). satisfaction suggests may be difference maximizes satisfaction.

Standardized methods for thermal comfort assessment already exist, namely the predicted mean vote (PMV) and adaptive model, both valid groups of people. To identify whether a specific person is comfortable under different factors such as thermal, air quality, lighting, acoustics, only current reliable method subjective evaluation. reduce need occupant feedback, personal models are currently being developed that aim to predict response based on information from its surroundings. These leverage machine learning tools have been found provide suitable estimations responses. According literature, an average prediction accuracy 70–80% attainable. Therefore, these promoted innovative efficient ways comfort-based HVAC control. The challenge however identifying most relevant indicators acquiring them in simple way. Integrating anthropometric data, e.g., age, sex, body mass index may represent generating model. Including physiological data skin temperature, heart rate, signal transformation could increase performance. Strong relationships were identified between indicators, their variation was not be governed solely by thermoregulation. Few automatic control implementation examples using shows challenges still exist. In order achieve accurate control, certain issues remain regarding acceptable thresholds model performance optimum set combination it.
