1. Next Century Power: Energy Efficiency Opportunities in Newer K-12 Schools Senate Energy, Utilities and Communications Committee February 19, 2013 David Jacot, P.E. Director of Energy Efficiency

2. Energy Efficiency & Newer K12 Schools Introduction Los Angeles Department of Water and Power (LADWP) Serves 4M residents Largest POU in the US Largest POU Energy Efficiency portfolio in the US Los Angeles Unified School District (LAUSD) 640,000 students 2 nd largest school district in the US 600 schools in LADWP territory 2

3. Energy Efficiency & Newer K12 Schools LADWP/LAUSD EE Achievements Since 2008, LADWP and LAUSD have partnered to: Retrofit over 60 schools Save over 15M kWh/yr Reduce bills $2M/yr Strategies for Energy Efficiency Audits & Benchmarking Rebates and Incentives for EE measures Direct Install approach Retro-Commissioning (RCx) New Construction design assistance 3

4. Energy Efficiency & Newer K12 Schools Need for EE in Newer K-12 Schools “Young” schools can have “old” systems Building system lifecycles Lighting – 10-15 yrs HVAC – 15-20 yrs Other processes – technology evolves in 5-15 yr cycles Computers, Office equipment, Plug loads Food service equipment Athletic facilities Advancing codes & standards requirements California Energy Code – 5 versions in last 15 years Lighting HVAC Building envelope Etc. 4

5. Energy Efficiency & Newer K12 Schools Need for EE in Newer K-12 Schools New construction often occurs on existing campuses Ex: El Camino High – Built in 1949, additions in 1956/60/61/69/75/86/88/97/98 Ex: Evans Adult School – Built in 1914, additions in 1915/41/54/72/73/81/92 Some newer schools not built with optimal efficiency Three main types of missed opportunities EE measures not included in design EE measures in design but not installed EE measures installed but not commissioned/operated properly Typical reasons for missed opportunities “Value engineering” and budget reallocations (due to material price increases during early 2000s, etc.) Disconnect between Capital and O&M budgets and operations Limited utility design assistance and commissioning support 5

6. Energy Efficiency & Newer K12 Schools Addressing EE opportunities in Newer K-12 Schools LADWP and LAUSD are partnering to bring EE to all schools, including newer schools Obsolete systems – Incentives, Direct Install EE measures not installed – Incentives, Direct Install EE measures not operable – RCx Retro-Commissioning Building “tune-up”; low-cost/no-cost measures Ex: Reset lighting timers and daylight/occupancy sensors Ex: Fix economizers on HVAC equipment LADWP is performing RCx for LAUSD LADWP is also training LAUSD staff and providing support 6

7. Energy Efficiency & Newer K12 Schools Case Study – LA Academy Middle School LA Academy Middle School Built in 1998 1800 students Highest energy use per square foot in entire district LADWP/LAUSD Partnership approach (Fall 2012) Retrofit lighting systems – Direct Install Add occupancy sensors – Direct Install Reset lighting controls for summer – RCx Expected annual energy savings: 40%, or 1M kWh 7

8. Energy Efficiency & Newer K12 Schools Conclusion Newer K-12 schools present EE opportunities that should not be overlooked Savings potential can match older schools Utility Incentives, Direct Install, and RCx approaches address these opportunities Schools will best maximize EE opportunities by working closely with the utility LAUSD’s partnership with LAUSD is yielding significant results, for both older and newer schools 8
