Abstract: In order to retain good indoor air quality through the year in detached houses with passive ventilation systems, the author investigated a mechanical control air-supply method using a simulation program: “Fresh2015”. Fresh2015 simulates indoor environments in the houses with two types of structures and four types of ventilation systems. The simulation results showed that this mechanically controlled air-supply opening keeps ventilation rates adequate and makes the indoor air quality good from winter to the mild season especially in airtight houses.
