Other Motivating Factors
•
•
•
•
•
•
•
12/2/2008
Large number of existing facilities--700 locations
Utility fund shortfalls
$400M deferred maintenance backlog
Need for an “across the board” fix
Need “boots on the ground” quickly
Limited staff resources
Cost!

Why Lighting?
•
•
•
•
•
•
Easy and Non-invasive
Upgrades increase quality and productivity
Highly visible to building occupants
Improved reliability & maintainability
2-5 year payback
Low-hanging fruit
Environmental Impact

Technical Considerations
• Lamp: lumens, color, life, warranty
• Ballast: input watts, ballast factor, instant start
vs. rapid start
• “High Performance” T8 system ≥ 90 LPW
• Luminaire: Lens, Reflector, Environment
• 4-lamp to 2-lamp reflector kits save 75%
• Controls

Execution Method
•
•
•
•
•
•
12/2/2008
No A/E needed
In-house audits & inventories
Direct materials purchase--no contractor markup
Labor-only contract hire (specialty firms)
Multiple crews, one per building
Staff electricians where practical
Side Benefits
•
•
•
•
•
•
•
Improved quality of light (CRI)
Eliminate magnetic ballast flicker
Improved lumen maintenance (quantity)
Occupants report very positive response
Remove PCB-containing and high-mercury materials
Less trash and waste than new fixture purchase
Lamp/ballast warranty & reduced maintenance needs
Lessons Learned (so far…)
•
•
•
•
•
•
12/2/2008
Consider sensitive areas & need for shift work
Contact department staff prior to start date
Have a recycling plan before you start!
Identify a secure lay-down area for materials
Labor costs on per-fixture basis
Keep room-by-room “as built” records
Triple Bottom Line
