The new standard will be a companion piece to the Energy Rating Index.
RESNET is partnering with the International Code Council (ICC) to develop a national consensus standard for the rating of a home’s water efficiency, the Water Rating Index. The new standard will be a companion piece to the Energy Rating Index.
“In many parts of the nation, water is fast becoming an ever increasingly expensive commodity," RESNET Executive Director Steve Baden said. "There is clearly a need for a system to rate a home's efficiency in water use. This will allow home buyers to know how efficiently water is being used in the homes they are considering buying. It will also provide an opportunity for home builders to monetize the efficiency of their homes in the same fashion that the HERS Index plays for energy efficiency."
