Colorado Energy Office to Use RESNET HERS® Index Scores to Promote Building of High Energy Performance Homes

OCEANSIDE, CALIFORNIA--(Marketwired - Sept. 9, 2013) - The Colorado Energy Office and the Residential Energy Services Network have entered into a Memorandum of Understanding (MOU) to promote and track the market trends of new, Home Energy Rated System (HERS) rated homes across the state of Colorado.

The purpose of this agreement is to increase consumer knowledge and awareness of the energy performance of new homes through the use of the HERS Index. Created by RESNET, the HERS Index is the industry standard by which a home's energy efficiency is measured. It is also the nationally recognized system for inspecting and calculating a home's energy performance.

Under the terms of the memorandum, the Colorado Energy Office will provide quarterly and annual reports to real estate professionals, and the general public, regarding the use of the HERS Index Score for marketing new homes. In turn, RESNET will provide a quarterly and annual review of all newly built homes in Colorado that have HERS Index scores. Included would be statewide information about:

  • The number of new and existing homes that received a HERS rating.
  • The average HERS Index Score of the new homes.
  • The numbers of new homes built with a HERS Index Score of 50-26, 25-1, and 0 or net-zero.

The agreement between the two parties supports the significant efforts already undertaken by the state of Colorado in promoting residential energy efficiency, and the construction of high-performance energy homes throughout the state. These efforts include:

  • Promoting the inclusion of the HERS Index Score in Multiple Listing Service (MLS) listings in Colorado. The Colorado Energy Office's Green MLS Initiative covers 97% of all residential homes in Colorado. This provides an option to add the HERS Index Score as a searchable feature.
  • Highlighting the HERS Index Score in the Colorado Energy Saving Mortgage Incentive, which provides greater benefits as homebuyers move towards Zero Net Energy (ZNE) homes.
  • Developing consumer information and outreach around the HERS Index and builders that offer a net-zero or near net-zero energy package.

Other states interested in following Colorado's lead can look to this memorandum as a model to understanding the value that energy efficiency information brings to their new home markets.
