Next Century Power: Energy Efficiency Opportunities in Newer K-12 Schools

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 • 2nd 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
