Living standard of people is increasing significantly recently and due to this fact energy requirements are also increasing. At the Technical University in Kosice a research examining the quality of indoor environment is carried out. There exists a constructed research centre, where an experimental house with passive standards in terms of building structures is designed. Heating and ventilation can be modelled in the house. Equipment is designed on the basis of calculated balances for the needs of heat, hot water demand and the need for ventilation of the building. This paper highlights the importance of environmental protection regarding the reduction of energy consumption while keeping the living standard. In low energy houses, up to 80% of the total heat is consumed for the heating of fresh air for a comfortable environment. The aim of this article is to examine the effect of temperature, humidity, air velocity and CO2 concentration in regard to the human behaviour in indoor environment with natural ventilation, i.e. without a ventilation device, where ventilation is forced or an air conditioning.

Keywords: ventilation; airflow rate; legislative; carbon dioxide (CO2), concentration.
