Title: Roof overhang design for solar control

Abstract

Design formulas are developed for both fixed and extendable overhangs as a function of window height, geographic latitude and solar altitude. The extendable overhang is adjusted seasonally. Design parameters are suggested for near optimum solar control in direct-gain passive systems. A method of estimating the effect of an overhang on solar gain is also developed. Examples of the solar performance for both fixed and adjustable overhangs are presented for 36/sup 0/N latitude.
