“The key to everything is patience. You get the chicken by hatching the egg, not by smashing it.” -Arnold H. Glasgow The ANSI/RESNET/ICC Standard 850 was developed over the course of years via consensus input from over 75 organizations. The standard was first issued in 2020 and is now seeing increasing use. Several steps needed to take place before the California Energy Commission’s accredited rating providers were approved by RESNET as HERSH2O providers. At the same time, the demand for the HERSH2O rating service had to be built along with the ability to provide the service itself. We are joined today by Russ King (Senior Director of Technical Services for CalCERTS, Inc.) and Ryan Meres (Program Director for RESNET) to learn more about the rollout of HERSH2O in California. Ryan shares background on the HERSH2O Standard and how it is being used to achieve the EPA WaterSense Label along with RESNET’s efforts to get the standard recognized as a compliance method for California’s Model Water Efficient Landscape Ordinance (MWELO). Russ describes for us the CalCERTS network of CA HERS Raters and how they can get certified for HERSH2O and WaterSense through CalCERTS. Russ and Ryan will improve your understanding of the topic leveraging their extensive and diverse backgrounds. Learn more on how this all works at www.calcerts.com/water/.
