A roomin a building has a living etc. spaceof volume V that is an enclosed space. Ventilation of an air flow F is performed from the outside to the living etc. space. Entering/exiting of air as an air current between the inside of the living etc. spaceand the outside is eliminated, and at least a part of the boundary between the living etc. spaceand the outside is configured from a gas exchange membranehaving a diffusion constant D, a thickness L, and an area A for gas molecules of interest. When air inside the living etc. spaceis sufficiently agitated and the concentration of gas molecules constituting the air is made spatially uniform, η(t) is controlled so as to vary according to B(m/s) is the gas consumption amount inside the living etc. space(t) is the gas concentration inside the living etc. spaceat time t, and η0 is the gas concentration of the outside.
