The report presents the results of an analytical study of the effect of shading devices on annual heating, cooling, and total energy use, on peak electric demand, and on energy cost savings in single-family residences, a small office, a school, and a high-rise office in Minneapolis, Minnesota. Using an hour-by-hour building energy analysis model, savings were simulated for interior and exterior shading devices. Energy cost savings were calculated using Northern States Power (NSP) Company utility rates; however, no analysis of the costs of installing and operating these devices was made. Results are presented in terms of annual energy cost savings and peak electric demand reductions, with each shading device in place, as compared to baseline reference cases for three prototypical residences and a prototypical small office, elementary school, and high-rise office building. The devices are ranked in terms of energy cost savings, as well as peak demand reduction. While the best-performing devices have annual cooling energy savings ranging up to over 30%, the annual energy cost savings (at NSP utility rates in effect in 1989) range up to only 4% for the residences and 10% for the office buildings, but less than 1% for the school. Summer peak electric demand reductions are more significant: up to 20% for the residences, 12% for the offices, and 3% for the school.
