Abstract

Energy Resource Station in Ankeny, Iowa was used to conduct experiments comparing daylighting controls to a conventional lighting system. Side-by-side pairs of test rooms on the east, west, and south sides of the building were equipped with venetian blinds and tests were conducted in August, April, May, and June 2000 - 2001. Results showed savings in lighting energy up to 50% over a conventional system. Reheat and chiller energy usage were also examined. It was found that total energy (reheat, chiller, and lighting energy combined) was saved using daylighting for 24 of the 32 test days when all energy sources were combined. Maximum total energy savings was 29% for two days in June. The experimental results were used to validate a DOE-2.1E computer simulation. The simulation was able to predict total energy savings to within 11% of the experimental results. In most cases, DOE-2 overestimated energy usage.
