UIUC Sustainability Goals
• • • • • Energy reduction policy – 10% in 3 years • • • • Signatory to American College and University Presidents Climate Commitment • Required to develop plan to reach carbon neutrality New construction must be LEED Silver Certified at a minimum.
• Business Instructional Facility Lincoln Hall Renovation Huff Hall Addition NCSA Petascale Computing Illinois Fire Service Institute Several aspects of sustainability in Campus Strategic Plan Need for comprehensive sustainability policy

Other Motivating Factors
• • • • • • • 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

ICECF Energy Efficient Lighting Upgrade Grant Program
Incentive based on demand reduction (60¢/watt) Applicable to new or retrofit fixtures Fluorescent, HID, LED exit signs, controls Must apply & be pre-approved Reimbursement after project completion
12/2/2008 • • • • •
DCEO Public Sector Electric Efficiency Program
http://www.illinoisenergy.org
Incentives based on Prescriptive methods • Many specific upgrades & replacements • High-Performance T8: $7.00/lamp Custom incentive option available (7¢/kWH) Must apply & be pre-approved Reimbursement after project completion

UIUC Campus Lighting Retrofit data
• • • • • • 44 buildings representing ~7M sq.ft.
Highest energy users Linear fluorescent T12 to High-Performance T8 Estimated total cost $4.2 million Project budget $2.8 million ICECF commitment $1.18 million
12/2/2008
UIUC Campus Lighting Retrofit data
• • • • 80,233 light fixtures 2.9 MW reduction ~$900,000 annual cost savings (12 hr/day) 12.8 million kWh saved per year

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
Other Lighting Upgrade Programs
• • • • • New construction / LEED Remodeling CFL replacement as routine maintenance LED Exit signs (DCEO) Targeted applications & individual projects • • • Gymnasiums Pools / Ice Rink Warehouses

Execution Method
• • • • • • 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
12/2/2008
Lessons Learned (so far…)
• • • • • • 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
