A. 1) In favorable climates and buildings types, natural ventilation can be used as an alternative to air-conditioning plants. 2) At interior air velocities of 160 fpm, the perceived interior temperature can be reduced by as much as 5°F. 3) Wind can blow air through openings in the wall on the windward side of the building, and suck air out of openings on the leeward side and the roof. 4) Temperature differences between warm air inside and cool air outside can cause the air in the room to rise and exit at the ceiling or ridge. 5) Power ventilation can be accomplished in two ways. 6) In homes not mechanically cooled (air conditioned) the temperature can be controlled to some extent by the use of attic fans. 7) Sufficient outlets must be installed in the attic to exhaust the air without creating high pressures against which the fan must operate. 8) The net area of attic outlets should be 1/800th of the rated fan volume in cfm and 1/8 inch static pressure. 9) The outlets should be distributed uniformly. 10) Air conditioned homes can use power attic ventilators by installing an exhaust fan through the roof or in the gable. 11) Inlets for the ventilating air should be at the soffit, or the opposite gable, when no roof overhang exists. 12) For well-insulated ceilings it is doubtful that power ventilation can be justified economically. 13) There are some attics which cannot be ventilated by gravity or wind-assisted methods. 14) Consideration should be given to the use of a power ventilator with automatic or motorized inlet louvers. 15) Ventilation can be shut off during a dust storm to prevent the buildup of dust and sand in the attic.
