Displacement ventilation in a lecture hall, a case study.

                  

Envelope leakiness of large, naturally ventilated buildings.

Whole-building pressurisation tests can quantify the air-leakiness of a building's external envelope. The resulting information can be used in assessing the quality of the building fabric. At present there is little information regarding the leakage characteristics of large, non-domestic UK buldings. As a step towards providing more information, the Building Research Establishment (BRE) has developed and constructed a multifan pressurisation system known as BREFAN to pressurise large buildings like offices and hangars.

Experimental analysis of air diffusion in a large space.

An experimental study in reduced scale model for ventilation inside a sheep-fold has been studied. The ventilating system consist of two slots in opposite side walls and one in the roof, Two-dimensional jet are generated by the wind effect and temperature difference acting upon the sheep-fold.
