Abstract

This article will illustrate the effects of daylighting as a major conservation and load management strategy for a theoretical eight-story office building of 120,000 gross square feet. Holding the basic building design constant, the benefits of daylighting will be analyzed for five different cities (New York City, Phoenix, Chicago, West Palm Beach, and San Francisco) and their utilities. For purposes of space, the detailed analysis will be limited to implications for New York City which has an existing stock of over 250 million square feet of office buildings.
