Field Commissioning of a Daylight-Dimming Lighting System David B. Floyd Danny S. Parker Florida Solar Energy Center 300 SR 401, Cape Canaveral, FL 32920 USA Abstract An Elementary School cafeteria in Florida was commissioned with a fluorescent lighting system that dims in response to available daylight. The lighting system's performance and commissioning aspects were evaluated through real time measurement of lighting and air conditioning power, work plane illumination, and interior/exterior site conditions. The new system produced a 27% reduction in lighting power due to dimming. Lower than expected dimming system performance was observed prior to effective commissioning. Difficulties encountered are discussed as well as recommendations for performance improvements. Back to Right Light Proceedings startpage Top of page
