Résumé

There are various contaminants in habitable buildings (from people, animals, equipment, lighting, etc.). In standards and regulations, one can find minimum airflow required for ventilation according to indoor air quality category. Poland is not the only country where natural ventilation is one of the most popular types of ventilation systems. Natural ventilation does not always work properly, does not supply required airflow. Therefore, there are symptoms of Sick Building Syndrome, excessive amount of carbon dioxide and water vapor and a risk of carbon monoxide presence. The idea of passive buildings is to minimize energy loss to the environment therefore new designed passive buildings have 100%: sealed windows, doors, walls. Passive buildings need mechanical ventilation systems but owners do not always install such system because of some disadvantages (noise, space for ductwork, air handling unit, intake and exhaust opening, investment cost etc.). The paper presents short characteristics of air pollution in average building, simple calculation of energy required for ventilation and some real problems with mechanical ventilation systems.
