Professional Builder Magazine Covers RESNET’s Efforts to Develop Water Efficiency Rating Index

Jun 25, 2015

RESNET has embarked on an effort to develop a Water Efficiency Rating (WER) Index.  The water rating system will be based on the RESNET HERS® Index.  The goal is to have certified RESNET HERS® Raters be able to produce a WER Index of a home at the same time the home is inspected and a HERS® Index is produced.

The latest issue of Professional Builder Magazine features a story on the effort to develop the RESNET WER Index.  The story describes how the rating system will assign “a numeric score to a house based on its water usage.”  It states that it is being developed by RESNET and a coalition of water efficiency experts, homebuilders, environmental organizations and home energy professionals.”

The feature quoted Ed Osann of the Natural Resources Defense Council, “A numeric score will help homebuyers understand the water efficiency of a house the same way car shoppers use fuel efficiency labels to inform their purchase decisions.  The score will help expand green building programs and encourage new rebates and tax incentives for water efficiency products in new and existing homes.  Consumers who ‘know the score’ will save water and money when they buy a home or renovate an existing home.”
