Passive cooling techniques are least expensive means of cooling a home which maximizes the efficiency of the building envelope without any use of mechanical devices. It rely on natural heat-sinks to remove heat from the building. They derive cooling directly from evaporation, convection, and radiation without using any intermediate electrical devices. All passive cooling strategies rely on daily changes in temperature and relative humidity. The applicability of each system depends on the climatic conditions. These design strategies reduce heat gains to internal spaces.
– Natural Ventilation
– Shading
– Wind Towers
– Courtyard Effect
– Earth Air Tunnels
– Evaporative Cooling
– Passive Down Draught Cooling
– Roof Sprays
- Here is a presentation on PASSIVE COOLING TECHNIQUES which i have prepared. Hope you get all the information you ever needed.
