This study investigates the impacts of the three different types of carpark namely open (on surface), multistory and integrated carpark. The 1:200 scaled models were used in wind tunnel to gather pressure distribution data on the exterior surface of surrounding housing blocks. The data were collected from testing the various wind directions on different types of carpark. Using pressure coefficient (Cp) values, the ventilation performances represented by air change rate (ACH) in the selected units were calculated using CONTAM.
It is the aim of this article to explain the testing procedures developed at the University of Technology, Sydney (UTS) and to evaluate the potential natural ventilation and daylighting applications that have arisen from this research. The objectives for research into this field were to reduce energy costs and increase the sustainability of building stock. From the results of these experiments actual and potential designs are illustrated and discussed in this article.
In the mid-1980s, two London architects postulated that deflection of higher speed air from tall slab buildings could increase air infiltration from a neighbouring low-rise block, increasing its associated ventilation heat loss. These issues have been of much concern during the past two decades among designers, developers and local authorities; especially those considering in-fill near tall buildings. This preliminary study looks at the ventilation and space-heating loss of a three-storey low-rise office block located near a taller nine-storey slab building.
