The Water Energy Nexus: Demonstrating Energy Savings in WaterSense-Labeled Homes

IAPMO Season 4 Episode 14

In this episode, Jonah Schein, Technical Coordinator for Homes and Buildings with the U.S. Environmental Protection Agency (EPA) WaterSense® program, demonstrates how water-efficiency measures also save energy and reduce carbon emissions, using data from 219 WaterSense-labeled homes in Menifee, California.  

Jonah describes how every gallon of water has an "energy signature" based on the processes required to extract, convey, treat, and distribute that water, noting the dramatic differences among various water sources, with some requiring over 20 times more energy than others. Noting the benefits of right-sizing plumbing pipes for water-efficient fixtures, Jonah emphasizes the tremendous opportunity in leveraging water efficiency to cost-effectively reduce energy use and carbon emissions.
