Natural ventilation of parking garages.

A combination of a wind-tunnel investigation and a mathematical simulation technique conducted on models of two-storey parking garage situated beneath alarge block of buildings (consisting of houses, shopping centre and offices) shows that wind penetrating the partly open garage facades can provide sufficient ventilation. Studies the effects on ventilation of varying the open area of the facades and of fitting openings in the garage roofs. Measures the effect of such ventilation means on air quality close to buildings.
