1. Demand Side Energy Management & Conservation Lighting Retrofits The University of Texas at Austin

2. The University of Texas at Austin 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 University Profile 2

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. 4 Energy Use and Production

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

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

7. 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 The Process Audit, Measurement & Verification 7

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