In low energy dwellings the ventilation heat losses are significant. Reducing this heat losses can be done by introducing demand controlled ventilation i.e. ventilating at a normal rate only when rooms are occupied. Simulations, using TRNSYS 14.2, of a dwelling, equipped with a demand controlled ventilation system are carried to determine the extra conservation on natural gas for space heating. Demand controlled ventilation schedules are used in the simulation program by using typical Dutch occupation schedules of a four person family for the dwelling. Preliminary results indicate an extra energy conservation of 15- 20% with regard to the reference situation.
