A system for heating and ventilating a building which includes a generally peripheral foundation element (1) which supports the external walls (11) of the building. Room air is heated and circulated below the floor and up through floor openings (26) at the external walls (11). A barrier (15) is connected to the foundation wall (1) so as to span the area enclosed by the foundation wall (1) at a level beneath the floor (25). Exhaust air is conducted to a region (7) beneath the barrier (15) for surface-enlarged contact with the underside of the barrier (15). The foundation element and/or the base (17) that supports the foundation element is permeable to air along essentially its full length beneath where the foundation element connects with the barrier and exhaust air flows out through the foundation element or its supporting material while effecting an exchange of heat therewith. |
