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.
