December 2, 2008 Campus Lighting Retrofits University of Illinois at Urbana-Champaign in conjunction with ICECF Eva Sweeney, P.E., LC, LEED© AP ISTC Sustainability Series Tuesday, December 2, 2008

12/2/2008 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

12/2/2008 Urbana Campus Energy Costs FY 2003:$26,612,000 FY 2004:$35,684,000 (+34%) FY 2005:$52,282,000 (+47%) FY 2006:$70,778,000 (+35%) FY2007:$58,830,000 (-17%) FY2008:$78,449,000 (+33%) FY2009?

12/2/2008 Big Ten Energy Usage, 2007

12/2/2008 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

12/2/2008 Environmental Impact

12/2/2008 Illinois Clean Energy Community Foundation Four projects currently at UIUC Biomass (Miscanthus) Power Plant ($825K) Wind Turbine ($2.0M) Campus Lighting Retrofits ($1.18M) Business Instructional Facility ($75K)

12/2/2008 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 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

12/2/2008 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

Building Audit Spreadsheet

12/2/2008 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

Fluorescent Lamp Data

12/2/2008 Lamp Lumen Maintenance

12/2/2008 Ballast Data

12/2/2008 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
