Tools and Resources
WaterSense has developed resources to help builders and other professionals in the building industry learn about the features that help to make a home more water-efficient. While many of the tools on this page were developed to support Version 1 of the Homes specification, and include language that speaks to its requirements, the information can still be useful to building professionals. Looking forward, WaterSense will be updating and revising these tools to respond to changes made for Version 2 of the program.
