2021 Trends in HERS-Rated Homes
In 2021, over 313,153 homes were HERS Rated using RESNET Standards. This is the most in one year and increases the total number of rated homes to over 3.3 million. This article dives into the data from 240,000 of those rated homes.
Building America: Continuous Insulation
Includes information on related codes and standards requirements, and criteria to meet national programs such as DOE’s Zero Energy Ready Home program, ENERGY STAR Certified Homes, and Indoor airPLUS.
Guidelines for Participating in the DOE Zero Energy Ready Home Program
DOE Zero Energy Ready Homes are verified by a qualified third-party and are at least 40%-50% more energy efficient than a typical new home. The DOE Zero Energy Ready Home is a compelling way to recognize builders for their leadership in increasing energy efficiency, improving indoor air quality, and making homes zero energy ready.
