HERS H2O has been more than three years in the making. In February of 2018, the first version of HERS H2O was approved by the RESNET Board. It builds off of RESNET’s widely used HERS Index to provide a new system for rating whole house water efficiency. Water resources are becoming increasingly strained in many parts of the country and water prices are increasing faster than energy prices. HERS H2O will provide homeowners with a simple way to compare the water efficiency of homes they are looking to buy; just like the HERS Index does for energy efficiency. HERS H2O takes into account both indoor and outdoor water use and is grounded in water use data. HERS H2O underwent a formal pilot phase from June through December, 2018 and is expected to remain in pilot until its full launch later in 2019.
This webinar will cover the principles of water efficiency, the components and process for doing a water efficiency rating, conducting an inspection for a water rating and the impact of indoor and outdoor water use on a HERSH2O rating in different regions.
