Natural Ventilation Natural Ventilation should be an important component of every architectural design in every climate zone.
Natural ventilation removes hot air from a space.
Ventilation affects cooling, if the air moves fast enough, by increasing the rate of evaporation from the skin of occupants. Properly designed natural ventilation solutions can result in savings in both capital costs and energy. In addition, it is also desirable to minimize the requirement for mechanical ventilation and air-conditioning systems in order to ensure a 'healthy' building. The use of natural ventilation is overwhelmingly supported by the fact that energy consumption is typically around half that of air-conditioned buildings in cases where natural methods are used. In addition, maintenance is reduced, there are fewer incidents of 'sick building' syndrome, and there is a reduction in carbon dioxide emissions.
