The City of Los Angeles established the Existing Buildings Energy and Water Efficiency (EBEWE) ordinance in 2017 to encourage building owners to reduce energy and water consumption through benchmarking and performance requirements. Under the EBEWE ordinance, the City of Los Angeles requires that all buildings over 20,000 square feet (including municipal buildings over 7,500 square feet) conduct annual benchmarking of their energy and water use and then take action to reduce their consumption.
Additionally, the State of California AB 802 followed by establishing a statewide building energy use benchmarking and public disclosure program under AB 802. AB 802 revises PRC Section 25402.10 to require utilities to provide energy consumption data for covered buildings to the building owners upon request, and requires the Energy Commission to establish a building energy use benchmarking and public disclosure program for certain buildings. A summary of the benchmarking provisions in AB 802 can be found on the CEC's website.
Benefits of Benchmarking
Benchmarking efforts allow owners and occupants to understand their building’s performance and identify the following opportunities:
- Building owners may see cost savings through lower utility bills, and reduced maintenance and operating costs.
- While water and electric bills can go down, property value may go up.
- Those working in the building get a more comfortable and healthier work environment.
- All Angelenos benefit from reduced carbon pollution by offsetting the need for generating energy from traditional fossil fuel power sources.
To help streamline the process, the City of Los Angeles has established the LA Benchmarking Help Center, funded by LADWP, to provide free technical support on Energy Star Portfolio Manager (ESPM), including:
- Data acquisition
- Data Review
- Turning benchmarking results into savings opportunities
The ENERGY STAR® Portfolio Manager® is a free online tool that allows you to track the energy and water use for the entire building, and comply with the City ordinance and State Legislation. Use Portfolio Manager to:
- Generate weather-normalized energy use intensity and greenhouse gas emissions metrics for your building
- Get an ENERGY STAR energy performance score between 1 and 100 for many eligible buildings.
- Create custom reports that enable users to view time-trending information and compare buildings within your portfolio.
LADWP has established an interface with the ENERGY STAR® Portfolio Manager® that will enable you to benchmark your building’s energy and water consumption.
