Performance of Ventilation in Residential Buildings
The aim of this study was to survey the performance of ventilation in residential buildings. Particularly the effect of various ventilation systems on air-exchange rate in rooms, indoor air climate, satisfaction and health was studied. The research was carried out with field measurements and a questionnaire to inhabitants. Seven apartments in small houses and six apartments in block of flats were selected into the research. There were different kinds of ventilation systems in the apartments. The air-exchange rates in the dwellings varied a lot; the ventilation rates were from 0.1 to 0.7 l/h. Only in three dwellings the official minimum ventilation rate 0.5 l/h was achieved. The lowest air-exchange rates were measured in the dwellings where the mechanical ventilation system was usually not in operation. The ventilation rates were then only about 0.1 l/h. The ventilation rates were about 0.4-0.5 l/h in the dwellings with natural ventilation. Closed bedroom doors reduced the air-exchange rate in the room, except in the dwellings with mechanical air supply into each room. A quiding correlation was found between the air-exchange rates of the dwellings and the satisfaction and health of the inhabitants. When the ventilation rate was low i.e. under 0.3 l/h, the inhabitants were usually not satisfied with the performance of the ventilation system. Similarly the symptoms of tiredness and the symptons from respiratory organs were more common, when the ventilation rate was low. (ERA citation 13:036614)
