EPA Launches 1-100 Water Score in ENERGY STAR® Portfolio Manager®

October 18, 2017 | ENERGY STAR

On October 8, 2017, the U.S. EPA launched the new 1-100 water score for multifamily properties in ENERGY STAR® Portfolio Manager®. Consistent with the approach for the 1-100 ENERGY STAR score, the EPA 1-100 water score allows multifamily owners and managers to see how their property’s water consumption compares to similar properties nationwide.

While all building types can benchmark water use in ENERGY STAR Portfolio Manager and track performance over time, this is the first 1-100 water score available for any building type. The score is based on data from the Fannie Mae Energy and Water Market Research Survey, and was developed by EPA’s WaterSense® program, in partnership with ENERGY STAR. Visit EPA 1-100 water score for multifamily properties for details.

Data needed to obtain a score To receive a score, the following inputs are required in ENERGY STAR Portfolio Manager:

  • 12 full months of whole-property water use data
  • Property location
  • Gross floor area
  • Number of units
  • Total number of bedrooms
  • Irrigated area
  • ENERGY STAR Portfolio Manager generates a water score based on this data, normalizing for weather and operations.

    Improve efficiency with help from WaterSense

    Multifamily properties with 20 or more units can use the 1-100 water score to identify high- and low- performing properties across their portfolio and target low performers for improvement. EPA’s WaterSense program is developing a comprehensive set of multifamily water efficiency resources to help owners and managers cut water costs.

    Get recognition with the IREM Certified Sustainable Property (CSP) certification

    The IREM CSP, available for existing multifamily communities, includes a water category. Water benchmarking is required, and IREM, a 2017 ENERGY STAR Partner of the Year, strongly recommends using ENERGY STAR Portfolio Manager to meet this requirement.

    Points toward certification are available for a variety of water efficiency activities, such as leak checks, installation of high efficiency fixtures, and improvements in water performance.

    Get started with your CSP application.
