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.

It has been difficult to find a similar rating for existing homes, but a new policy that went into effect on January 25, 2016 extends the Federal Housing Administration’s (FHA’s) Energy Efficient Homes (EEH) policy – historically limited to new homes – to existing homes.  Read more: Home Energy Score vs HERS Rating Score »

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.

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.

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.  Read more: Green Value In Real Estate »
