Measurement and Verification of Water and Energy Savings

CWEE routinely performs measurement and verification (M&V) of water, energy, and greenhouse gas emission savings for interested parties. The Center has experience working with water utilities of varying sizes in collaboration with the service territory’s electricity provider to conduct M&V studies to evaluate the resource savings of both technology interventions and water or energy efficiency programs. Please contact Kendra Olmos if you are interested in funding a similar study.

The California Department of Water Resources (DWR) is the sponsor of this project titled, “DWR Water-Energy Grants Evaluation Program: Measurement & Verification (M&V) of Water and Energy Savings”. CWEE will perform the M&V on DWR’s 2014 and 2016 Water-Energy Grant projects to determine water, energy, and greenhouse gas emission (GHG) savings. CWEE will evaluate onsite conservation savings by custom designing a retrospective study for each grant, utilizing customer water and energy data, and performing customer surveys. The center will also provide offsite embedded energy and GHG emission savings using its refined methodology for calculating the energy intensity of water systems. CWEE’s methodology for determining embedded energy using a data-driven approach allows for more accurate measurements resulting from water conservation, whereas regional embedded estimates may greatly under- or overestimate actual water system energy use.

Project objectives are the following:

  • Provide measured savings of grant projects for both direct onsite and offsite embedded energy and GHG emission savings resulting from water conservation.
  • Produce a manuscript detailing the methods for performing evaluation of various water-energy conservation measures/programs, statistical methods, and experimental designs that will serve as a resource for performing such evaluations in the future.
