Types of ventilation -

The natural forces of wind and temperature drive natural ventilation. It is caused by pressure differential between the interior and outside of a structure, as well as wind and temperature variations. Wind pressure on a building is determined by the direction, speed, and form of the structure. Temperature changes between inside and outside induce density variances in the air, resulting in pressure differences. (Fig. 2.9)

Ventilation and buildings -

There are four distinct techniques to organically ventilate a building:

a) Single sided ventilation b) Cross ventilation c) Stack effect d) Reverse stack effect
