The home building industry’s first and longest-running water rating system has applied to be a Home Certification Organization (HCO) and is nearing acceptance into the WaterSense Labeled Homes program.

Under Version 2.0 of the WaterSense Labeled Homes Program, HCOs are responsible for ensuring all certified homes meet a minimum efficiency threshold. The Water Efficiency Rating Score (WERS), owned and operated by the Green Builder Coalition, has undergone an initial technical evaluation by EPA staff and the Coalition’s application is currently being reviewed.
