- Abstract
- Measurements were made on a masonry building at Fort Myer, Arlington, Virginia to determine the effects of attic ventilation on energy requirements for air conditioning. Also, the National Bureau of Standards Load Determination computer program, NBSLD, was used to calculate the hourly room and attic air temperatures of this building for different values of attic air changes and the results were compared with measured values. Except for one day of testing, weather conditions during the testing period were similar. Experimental results for test periods of similar weather conditions indicated that the energy for air conditioning was greater, by as much as 7 percent, with attic fan in operation than without. In addition, in one case the total energy consumption (air conditioner plus attic fan) with attic fan in operation was found to be greater by as much as 17.5 percent, than that in which the attic fan was inoperative.
