“Plans to protect air and water, wilderness and wildlife are in fact plans to protect man.” -Stuart Udall There’s no way around it. Water is essential to life. Water, like energy, is an environmental resource and requires (demands?) more attention from all. In fact, we’ve talked about water in four previous episodes of RESTalk over the last 4 years. How does the EPA WaterSense program address this topic? What are the updates in WaterSense Labeled Homes 2.0? How does the HERSH2O rating work? Seasoned water efficiency professional Jonah Schein (US EPA) and Ryan Meres (Program Director RESNET), return to the podcast to give us updates on the EPA WaterSense Labeled Homes V2.0 and HERSH2O programs Jonah and Ryan share their thoughts and help us learn more about: • The move from a prescriptive to a performance-based approach • How to handle projects that started using Version 1.0 • The ease of access to proper training • Why water is important to the building industry For the latest information on the RESNET HERSH2O program, visit:https://www.resnet.us/about/hersh2o/ You’ll find information on the EPA’s WaterSense program at https://www.epa.gov/watersense You can purchase the ANSI/RESNET/ICC Standard 850-2020 at the ICC Store: https://shop.iccsafe.org/ansi-resnet-icc-850-2020-standard-calculation-and-labeling-of-the-water-use-performance-of-one-and-two-family-dwellings-using-the-water-rating-index.html The standard can be viewed for free at this link: https://codes.iccsafe.org/codes/resnet-icc.
