Abstract

The energy use for ventilation (heating and fan electricity) accounts for a large part of the energy use in residential buildings. For residential buildings, in many cases the building is occupied only part of the day, and further the pollution and moisture load generated by household activities varies during a day. Using demand controlled ventilation (DCV) has a great energy saving potential both regarding fan and heating energy. However, it is important how the ventilation is controlled in order to ensure an adequate indoor air quality, thermal comfort and avoid damages on the building. In this study different control strategies, control parameters, number of sensors and placing of sensors, number of zones are tested by modeling a single family house. Conclusions from the study are that the size of the energy saving depends on control strategy and system design and it is important to design and choose appropriate control strategy to obtain a good indoor environment.
