Passive cooling, also called natural cooling, is a passive solar energy technique that allows or augments the natural movement of cooler air from exterior, shaded areas of a building through or around a building. Key concepts are:

 

  • Locate windows in the upper floor of the building so that this space is solar-heated during the warm season open the windows when building cooling is needed

  • Allow fresh, cooler air to enter the building through the bottom floor; this air may pass through a duct in the ground so that it is further cooled

  • Close other windows in the building so that only cooler air from the lower level enters the building
  •  

    The heated air in the top of the building is naturally drawn outside and replaced with cooler air in the lower portion of the house. Essentially this is a chimney effect in the building.
