Natural Ventilation of Parking Garages

摘要

Parking garages having a width exceeding b = 50 m are usually equipped with means for mechanical ventilation. This may give rise to very high energy demands. A combination of a wind-tunnel investigation and a mathematical simulation technique conducted on models of a partly two-story parking garage situated beneath a large block of buildings consisting of houses, shopping center and offices shows that wind penetrating the partly open garage facades can provide sufficient ventilation. Effects on ventilation of varying the open area of the facades and of fitting openings - vides - in the garage roofs were studied. The effect of such ventilation means on air quality close to buildings - balconies etc. - was also measured.
