IAQ in Conference Room whit Surveys

Katarzyna Gładyszewska-Fiedoruk

Abstract

The work presents three basic air pollutants in the room, degrading the indoor air quality. The only source of pollution in the analysed room are people. The research was carried out in a building located in north-eastern Poland, in a temperate climate, in an area where the outside air is very clean. That is why air exchange is often carried out by opening windows (natural ventilation). That was also the case during the described experiment. In the room during the experiment there were 55 people, all of them doing the same physical activity, sitting work. The temperature and relative humidity of the air, the concentration of carbon dioxide in the room and the sound level were analysed. During the experiment, questionnaire surveys were also conducted. Respondents answered the same set of questions at the beginning and at the end of the meeting. The IAQ was low during measurements. Carbon dioxide concentration ranged from 1700-2000 ppm. The temperature was too low (18-19oC). The smell for the respondents was not perceptible. The noise during measurements ranged within 50 dB. It was a parameter that aroused the greatest dissatisfaction among the surveyed. They didn’t pay attention to a low temperature.
