Experimental investigations and CFD simulations were carried out to evaluate the performance of square and circular section wind - driven systems for natural ventilation application in buildings. Wind tunnel and smoke visualisation tests were conducted on a full-scale model based on a commercial wind catcher design. The experimental set-up consisted of each system being connected to a model test room. The devices were divided internally into four quadrants/segments for the purpose of air supply and extract.
A new theatre at Bedales school, designed by Hampshire County Architects, includes on Its green agenda a cooling system made from underground concrete pipes, through which cold air is driven.
