Save energy by illuminating stairwells and corridors only when they are occupied

March 01, 2009 |



Infrequently occupied areas such as stairwells and corridors can be energy hogs because the lights are needlessly left on 24/7. Occu-Smart bi-level light fixtures can reduce energy costs by illuminating these spaces only when necessary. The fixture features a built-in motion sensor and provides two levels of illumination: full output for when the space is occupied and code-minimum, standby illumination for when the space is empty. Users can set standby illumination at one of four light levels—5%, 10%, 20%, or 30%. An adjustable time delay allows users to customize each fixture to delay dimming from five to 30 minutes.

Applications: Any building with stairwells and corridors, especially hotels, hospitals, schools, offices, and multifamily residential complexes

Availability: Nationwide

Cost: $230 per unit

Options/Sizes: Available in 11 wall- and ceiling-mounted fixtures; optional battery backup provides light for up to 90 minutes in the event of a power failure

Environmental attributes: Can reduce energy usage in infrequently occupied areas by as much as 85%, according to the maker
