Perception of air quality and the thermal environment in offices

Butala, Vincenc (author), Muhič, Simon (author)

People's perception of the thermal environment and the quality of air in mechanically and naturally ventilated office environments is discussed. Interdisciplinary research of the indoor environment (technical and medical fields) was based on the simultaneous measurement of the thermal environment parameters, as well on as on surveying employees during their normal working activities. The survey sought to determine the health status and health problems of those surveyed in the 6 months prior to the study, as well as the current state of health and current subjective evaluation of the thermal environment and air quality. Deviations between the measured values evaluated by predicted mean vote (PMV) - predicted percent of dissatisfied (PPD) model (PMV-PDD) and the subjective evaluations of thermal environment of those surveyed were found. The subjectively stated reasons for the health problems of employees gave precedence to natural, as opposed to mechanical, ventilation, which is confirmed by the average absence from work for health reasons. An index of health was defined and analyzed for the people within a building. Significant correlations between indoor air parameters and the way people felt were found. Findings from the study indicate a significant role for the psychological factors and psychological state of the respondents when subjectively describing the indoor environment.
