New and Underutilized Technology: Bi-level Stairwell Lighting
The following information outlines key deployment considerations for bi-level stairwell lighting within the Federal sector. This information spans:
Bi-level stairwell lighting uses integral occupancy sensor motion detectors to monitor the stairwell. When occupancy is detected, the lights go to full level. When the space has been vacated after a programmed period, the fixture goes to a minimum level.
Bi-level stairwell lighting is applicable in most multi-story buildings.
Key Factors for Deployment
Bi-level stairwell lighting is a good technology to implement concurrently with an overall building lighting improvement project.
Federal energy savings, cost-effectiveness, and probability of success are ranked 0-5 with 0 representing the lowest ranking and 5 representing the highest ranking. The weighted score is ranked 0-100 with 0 representing the lowest ranking and 100 representing the highest ranking.
