New and Underutilized Technology: Bi-level Garage/Parking Lot/Pedestrian Lighting

The following information outlines key deployment considerations for bi-level garage/parking lot/pedestrian lighting within the Federal sector. This information spans:

• Benefits
• Application
• Key Factors for Deployment
• Ranking Criteria
• Resources

Benefits

Bi-level LED lighting uses fluorescent and LED lighting sources with bi-level motion sensors to reduce lighting levels when the parking area is not in use.

Application

Bi-level LED lighting is appropriate for garage, parking lot, and pedestrian areas. It can also be applied to pathway lighting where appropriate.

Key Factors for Deployment

Evaluate specific lighting and environmental requirements before deployment.

Ranking Criteria

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.
