The Home Energy Rating System (HERS) was developed by RESNET to measure a home's energy efficiency and issue a score to verify performance when compared to a standard home.

Utility Programs that Require HERS Scores

The Residential Energy Services Network, or RESNET, recently published findings from a new study conducted by the Consortium for Energy Efficiency about how utilities are encouraging the growth of energy efficiency in new home construction.

According to the Residential Energy Services Network (RESNET), there were 206,583 homes in the United States that were evaluated by a HERS Rater and issued a HERS Score in 2016.

This broke the record for the number of homes HERS rated in a year!

South Carolina Adopts Energy Rating Index

Fri, 2016-05-20 11:09

In a previous post, we discussed how some states are taking measures to support home energy efficiency and the RESNET HERS Index by adopting the Energy Rating Index compliance path from the 2015 International Energy Conservation Code (IECC).

Oftentimes, these states have outright replaced their existing energy code with the 2015 version, thereby inheriting the newest guidelines, like the ERI path.

A blog by Joan Glickman of the Department of Energy indicated that there is a 1 in 3 chance that a newly built home in the United States comes with an energy label comparing it to energy code. The label being referenced is the RESNET HERS Score.

IECC code book imageThe International Energy Conservation Code, which is updated every three years, serves as the national model energy code and becomes mandatory when adopted by a state or local jurisdiction. When a builder builds a home, he/she has to meet the current energy code for the jurisdiction in which the home is located.

The Rise of HERS Scores in Homebuilding

RESNET, or the Residential Energy Services Network, was founded in 1995. The concept grew out of a commitment to developing national standards for home energy auditing and home energy ratings.

Around the same time, the Building Performance Institute (BPI) was created. BPI also had a focus on home energy auditing. Until recently, BPI was not focused on home energy ratings. It is this piece that has helped RESNET climb to popularity.

More HERS Ratings Expected in 2015

The Residential Energy Services Network (RESNET) announced its collaboration with the International Code Council last week in an effort to help home builders transition to the new 2015 International Energy Conservation Code (IECC). In the upcoming version of the residential building code, RESNET's HERS Index will be an optional compliance path — some people are saying that this compliance path represents the most significant change coming to 2015 IECC.

Green Value In Real Estate

Property owners know that investments in energy efficiency will reduce the cost of owning and maintaining a home or building. Perhaps that’s why studies have found that buildings rated as energy efficient have higher occupancy rates, command higher rents, and sell for more money than similar, less-efficient properties. With the certainty of lower utility costs and increased comfort, homebuyers and tenants are often choosing energy efficient environments, regardless of the higher price tag.
