Abstract:

It is the policy of the Air Force to consider solar design applications in its new construction where there is a potential for significant savings of fossil fuel-derived energy. The required analysis, however, is often either not performed properly, or not performed at all. There is a requirement for a simplified preliminary analysis of solar applications so that such analyses may be more reliably accomplished. One aspect of passive solar design is daylighting, used to supplement electric light when conditions are appropriate. A computer program is developed to aid in preliminary daylighting analysis by automating two accepted design procedures the Zonal Cavity Method for interior lighting design and the Libby-Owens-Ford method for predicting interior daylightning. After a trial run, it is shown that the appropriate use of passive daylighting can save approximately 23 to 33 of kilowatt-hour lighting costs for a design light level of 70 footcandles. The author concludes that daylightning can offer significant potential savings in lighting costs. Author
