We dove quickly into the Water Efficiency Rating Sore or WERS system with Mike Collignon Executive Director & Co Founder of the Green Builder Coalition.  So quickly in fact that we did not have time to talk much about the other cool things the coalition is doing, so definitely check out their website in the show notes to find out how they are a uniting voice for sustainable home building especially for the custom builder community

In short, WERS is a performance-based water efficiency program for both new and existing residential properties. This approach to water efficiency preserves design freedom and product choice flexibility. Third-party analysis and data collection is utilized to generate both a score and predict water usage for single-family and multifamily properties. Especially here in the west and specifically in the southwest, more and more water utilities and jurisdictions are looking for ways to better manage water in the build environment so that builders can continue to meet our housing demand.
