The DOE is now receiving comments on the preliminary determination. More information can be found at http://www.energycodes.gov/regulations/determinations.
If the preliminary determination is finalized, then states would be required to update their codes to meet or exceed the 2013 standard. Currently, states must meet or exceed the 2010 standard, which serves as the commercial building reference standard for state building energy codes under the federal Energy Conservation and Production Act.
The DOE noted that the 2013 standard contains 52 positive impacts on energy efficiency that were incorporated into the analysis. These impacts included changes made through the public review process in which users of the standard comment and offer guidance on proposed requirements. Specifically the major positive impacts include:
