In low energy buildings and passive houses due to very low heating demands integrated heating and ventilation (VAV or DCV) systems are used to provide proper indoor climate conditions – thermal comfort and indoor air quality. Dynamic changes of indoor conditions result in permanent changes in air flow. Control systems have to follow those changes and on the other hand have to minimize energy consumption for the system as a whole. The article presents advanced simulation methods and the results of experimental investigation of control of variable volume system installed in passive house located in Poznań, Poland.
