Abstract

This study examines the control effects of a daylight dimming system for a small private office space in Anchorage (latitude: 61.13°N, longitude: 149.53°W) to suggest optimum daylight conditions for lighting controls. A series of computer simulations using Radiance and consecutive computations were conducted for various daylight conditions to determine the final dimming levels of a lighting system. Results imply that “Best” control performance occurred in June with clear and intermediate sky, when no blind was used. The lighting energy savings for those cases were 73.0% and 56.3% respectively. A “Good” performance happened in June with intermediate sky and its lighting energy savings was 45.9%. When horizontal blind conditions were used, a “Good” system performance was achieved for June with intermediate sky. For those conditions, an “Acceptable” performance was achieved for June with clear and intermediate sky, and March with intermediate sky. The 45° blind conditions failed to provide necessary illuminance for all daylight conditions. Prediction models for the linear relationship between desktop and photosensor illuminances by daylight were statistically acceptable for a significance level of 0.05. Strong linear relationships existed between them under no blind and horizontal blind conditions.
