WaterSense Labeled Homes Version 2.0

Last Updated: 03-22-2021

The WaterSense labeled homes program is designed to encourage the construction and purchase of water-efficient, high-performing homes. In 2020, EPA is rolling out Version 2.0 of the WaterSense labeled homes program. Version 2.0 minimizes mandatory requirements and transitions to a more performance-based efficiency requirement. EPA aims for these changes to remove many of the technical and administrative barriers many builders have encountered in building WaterSense labeled homes. WaterSense labeled homes Version 2.0 will increase flexibility, adapt to changes in the building industry, and expand the reach of the program so that a broader range of builders and professionals can participate. This webinar was presented on Novemeber 19, 2020. Contact the ENERGY STAR team to receive a recorded copy of the webinar.
