Energy Efficiency & Newer K12 SchoolsIntroduction

• 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

Energy Efficiency & Newer K12 SchoolsLADWP/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

Energy Efficiency & Newer K12 SchoolsNeed 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.

Energy Efficiency & Newer K12 SchoolsNeed 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

Energy Efficiency & Newer K12 SchoolsAddressing 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

Energy Efficiency & Newer K12 SchoolsCase 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

Energy Efficiency & Newer K12 SchoolsConclusion

• 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
