IMPACT OF CO_2 CONCENTRATION, TEMPERATURE AND RELATIVE HUMIDITY OF AIR ON THE HEALTH AND SENSE OF WELLBEING OF EMPLOYEES IN AIR-CONDITIONED AND NATURALLY VENTILATED OFFICES

摘要

The current sense of wellbeing and health of employees engaged in similar types of activities in both air-conditioned (AC) and naturally ventilated (NV) buildings were analysed using an IAQ assessment, measurement of thermal comfort parameters, and a survey of employees. A questionnaire concerning the current sense of wellbeing was given while concurrently measuring CO_2 concentration, air temperature and relative humidity in the given building. Suitable statistical methods and models were used. The employees in both analysed buildings connect most of their health problems and current unpleasant feelings to the indoor environment, although more so in the AC than in the NV building. Statistically significant connections between CO_2 concentration and current sense of wellbeing parameters were found.
