Modeling of Subjective Responses to Indoor Air Quality and Thermal Conditions in Office Buildings

Air conditioning is used to control air quality and thermal environment and has a significant impact on perceived indoor air quality, thermal conditions, health symptoms, sick-building syndrome (SBS), task performance, and productivity. Building occupants provide a rich source of information about perceived indoor air. Could this information be used to teach and adapt the heating, ventilating, and air-conditioning system to improve satisfaction with indoor air is the research question behind this paper's study. A Bayesian probability model was constructed for perceived air quality and perceived thermal conditions (temperature, draught, and air humidity). Indoor air-condition measurements (temperature, air velocity, velocity fluctuation, and humidity) and human-related background factors, obtained by questionnaire, formed the input data for the model. In the developed model, the human-related well-being factors influenced two threshold values, which describe the indoor air conditions where the occupant cha...
