A simple parametric study of ventilation.

A simple study is described which demonstrates the relative importance of the various parameters which determine ventilation, using basically the single-cell version of the British Gas multi-cell model. The graphs presented can be used directly to estimate natural and mechanical ventilation rates under a wide variety of simple conditions. By adopting a non-dimensional approach which introduces the concept of the whole house leakage Reynolds number, the basis is laid for a more general means of estimating ventilation from graphical data sheets.
