PCT No. PCT/SE95/00569 Sec. 371 Date Feb. 21, 1997 Sec. 102(e) Date Feb. 21, 1997 PCT Filed May 19, 1995 PCT Pub. No. WO95/32397 PCT Pub. Date Nov. 30, 1995A system for heating and ventilating a building which includes a generally peripheral foundation element which supports the external walls of the building. Room air is heated and circulated below the floor and up through floor openings at the external wall. A barrier is connected to the foundation wall so as to span the area enclosed by the foundation wall at a level beneath the floor. Exhaust air is conducted to a region beneath the barrier for surface-enlarged contact with the underside of the barrier. The foundation element and/or the base 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. |
