  1. Demand Side Energy Management & ConservationLighting RetrofitsThe University of Texas at Austin

  2. The University of Texas at Austin University Profile • Founded in 1883 – some infrastructures more than 100 years old • ~ 22 million gross square feet • 427 acres of Main Campus + 400 acres at Pickle Research Campus • ~50,000 students and ~20,000 faculty and staff

  3. Energy Use and Production • Generate our own electricity for main campus • Purchase water and natural gas • Estimated annual costs for FY 2009/10 greater than $38 million

  4. Energy Use and Production

  5. Main Campus Demand Campus Use (MMBTU) Campus Use – Production (MMBTU) Focus on Electricity and Steam Reductions

  6. DSEMC Retrofit Projects What We Accomplished – Lighting, Steam & Water • Electric: Fixture, lamp & ballast replacement, occupancy sensors • Water: Fixture replacement, aerators, flush valves, shower heads • Steam: Steam trap & valve replacement or repair

  7. The Process Conducted full inventory of 122 E&G buildings Utilized Federal Energy Management Program (FEMP) guidelines Developed project measurement and verification procedures Sampled existing conditions Measured performance factors (e.g., watts/fixture, gallons/flush) Estimated and verified savings at building level Audit, Measurement & Verification

  8. Lighting Project Case Study Example • Renewed or replaced more than 200,000 lighting fixtures • Installed 2,300 lighting occupancy sensors • Recycled 471 tons of materials

  9. Lighting Project Energy Conserving Lighting Products Ceiling Mounted Occupancy Sensor T12 Lamp (Top) vs. T8 Lamp (Bottom) Electronic Ballast Benefits • $1.9 million per year in lighting savings • 25 million KWh per year in electricity • More than 21 million pounds of CO2E emissions avoided • Lamps and ballasts warranties • 39% reduction in project areas Electricity for 1,500 averagehomes Photo References http://www.allproducts.com/ http://ep.yimg.com/ http://news.thomasnet.com/ http://www.hk-phy.org/ Source: City of Austin

  10. Lessons Learned

  11. Lessons Learned Main Campus Production – Plant Input MMBTU 1%

  12. Lessons Learned • Effective Communications Project Management Conservation Action Teams

  13. Lessons Learned • Design Build – Very Effective • Cautious use of energy “savings” as funding strategy • Leverage for Auxiliary Organizations • Communications as important as “savings” • Lighting is an “emotional” issue • Revisit Lighting Standards • Energy / Maintenance / Client Expectations • Are we “agile enough” for the technology 13
