Passive Cooling
The term "passive" implies that energy-consuming mechanical components like pumps and fans are not used.
Passive cooling building design attempts to integrate principles of physics into the building exterior envelope to:
- Slow heat transfer into a building. This involves an understanding of the mechanisms of heat transfer: heat conduction, convective heat transfer, and thermal radiation (primarily from the sun).
- Remove unwanted heat from a building. In mild climates with cool dry nights this can be done with ventilating. In hot humid climates with uncomfortable warm / humid nights, ventilation is counterproductive, and some type of solar air conditioning may be cost effective.

Famous quotes containing the words passive and/or cooling:
“We have not passed that subtle line between childhood and adulthood until we move from the passive voice to the active voice—that is, until we have stopped saying “It got lost,” and say, “I lost it.””
—Sydney J. Harris (b. 1917)
“A little cooling down of animal excitability and instinct, a little loss of animal toughness, a little irritable weakness and descent of the pain-threshold, will bring the worm at the core of all our usual springs of delight into full view, and turn us into melancholy metaphysicians.”
—William James (1842–1910)
