With one of the aims of the the proposed mosque to combine the Minaret with its ventilation system based on precedents like the Contact Theatre, employing a strategy that is appropriate is crucial. Above is a sketch of simple stack effect ventilation taken from Environmental Design by Randall Thomas. I have been fortunate enough to have discussed such methods with Randall. They are both interesting and can improve the energy efficiency of a building dramatically if considered from an early stage of design. It is essential that all architects understand at least the basic principles upon which methods such as this are based.

The Contact Theatre, Manchester by Short & Associates is a very good example of passive ventilation. The principle behind the mechanically assisted natural ventilation system of the Contact Theatre is quite simple. External cool air is brought in through a series of ground level vents which are fed to under the seating. As the air heats up is rises but the extraction is through constructed H Pots above the theatre. These H Pots create a negative pressure from cross winds to suck the air out, however this is sometimes assisted by mechanically by fans in the base of the stack. Above is a sketch showing the passive of air through the main theatre space.
