Experiment of cross ventilation

Cross-ventilation during summer months has long had an important influence on the environmental performance(livability) of residential buildings and other architectural structures. This research facility has been constructed with the ultimate goal of composing design guidelines that will provide a more rational and systematic foundation for good cross ventilation design. The facility contains a recirculating closed-circuit wind tunnel allowing wind flowing at speeds up to 18k.p.h. to be directed from any angle toward real size test buildings of various frontages, thus enabling the visualization and quantification of ventilation phenomena.
