摘要

Daylight harvesting has the potential for significant energy savings by bringing daylight into buildings while dimming or shutting off electric lighting. The availability of daylight generally coincides with utility peak demand periods, making daylight harvesting a particularly valuable tool for peak electricity demand reduction. However, control systems to enable daylight harvesting have faced many barriers including expensive com- missioning and unreliable operation. These barriers and initial research were discussed in depth in the LD+A "Research Matters" column in the April 2008 issue. California Lighting Technology Center (CLTC) has continued research over the past year to develop and commercialize a next-generation daylight harvesting system with automatic commissioning and increased reliability through use of two photo sensors. CLTC is working with Wal-Mart to demonstrate the product prototype in a retail store and with Watt Stopper/Legrand to commercialize the system. This article presents the continuing research and demonstration results from the Wal-Mart test store in West Sacramento, CA.
