Los Angeles Existing Building Energy and Water Efficiency Program (LA EBEWE)

The Los Angeles Existing Buildings Energy and Water Efficiency Program (LA EBEWE) is a City of Los Angeles program that requires building owners whose properties are located within the City of Los Angeles to conduct energy and water benchmarking, efficiency audits, and retro-commissioning (RCx) of their properties. The LA EBEWE program went into effect in 2017. Due dates to meet LA EBEWE program requirements are being rolled out over several years. The following outlines requirements for complying with Los Angeles’ EBEWE program and how Partner Energy can assist LA building owners with compliance.

Partner Energy’s Dana Weiss, LEED AP, GRI, MBA discusses the EBEWE requirement in detail in her webinar: Los Angeles Existing Buildings Energy and Water Efficiency Ordinance (EBEWE)


Benchmarking is required annually, while audits and retro-commissioning (RCx) are required every 5 years. Partner Energy assists with LA EBEWE compliance by  providing:

Annual LA EBEWE Benchmarking Requirement:

  • All buildings 50,000 sq. ft. and over are currently due
  • All buildings 20,000 sq. ft. and over are due June 1, 2019
  • All City Owned Buildings 7,500 sq. ft. and over

Compliance for buildings 100,000+ sq ft was December 1, 2017. With compliance for 50,000+ sq ft being June 1, 2018.

LA EBEWE Energy and Water Efficiency Audits with Retro-Commissioning Requirement – Every 5 Years

The LA EBEWE Energy and Water Efficiency Audits with Retro-Commissioning requirement starts in the year 2020 with deadlines due based upon the last digit of the property’s AIN number.

  • Starting 2020, all buildings 20,000 sq. ft. and over
  • Two paths to compliance
Performance PathPrescriptive Path
Energy RequirementsEnergy Star Certification

15% Energy Use Intensity (EUI) Reduction

Retro-Commissioning AND ASHRAE Level II Energy Audit
Water Requirements20% Water Use Intensity (WUI) Reduction

Meets Plumbing Code

Retro-Commissioning AND Water Audit

All pathways must be completed and/or certified by a California licensed architect or engineer.


Simple buildings without central cooling may perform retrofits to meet Prescriptive Path.
