For lowering the energy requirement for a room (2) ventilated by a ventilating system (11 to 17) of a building (1), windows (4) and opaque wall parts of the outside wall (3) are designed so that the heat transfer numbers (kF and kW, respectively) are smaller than 1 W/m2.K. In addition, the supply air flows into the room (2) near the floor (9) at the comfort temperature of at most 20°to 22°C. and an input velocity which does not exceed a maximum air velocity which is permissible for comfort conditions in an occupied zone.
