HERSH20 Rating Debuted at RESNET Building Performance Conference
New index to measure water efficiency so homeowners save on water utility costs
Homebuyers need to know how efficiently water is being used in the homes they are considering to buy. In response to this need RESNET is introducing its first ever water efficiency rating index, HERSH2O.
Similar to the HERS Index Score, this water index will rate the indoor and outdoor water usage of a home including the bathroom and kitchen, clothes washer, pools, and irrigation, while also accounting for leaks, excess pressure, and waste to derive a HERSH2O score. The score is derived by comparing the rated home to a reference home, which is typical of construction practices in 2006.
