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.
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.
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.
Continuous insulation makes achieving higher HERS rating scores much easier. These builders have committed to having all their homes rated to RESNET’s stringent energy efficiency standards.
The IECC provides a checklist for prescriptively meeting air sealing requirements. Requirements for blower door testing are also given
Air sealing is an important factor in reducing energy usage. Find resources for using foam sheathing as part of an air barrier assembly here.
