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!

12/2/2008

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

Illinois Clean EnergyCommunity Foundation

• http://www.illinoiscleanenergy.org

• Four projects currently at UIUC•Biomass (Miscanthus) Power Plant

($825K)

•Wind Turbine ($2.0M)

•Campus Lighting Retrofits ($1.18M)

•Business Instructional Facility ($75K)

• 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

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
