article analytically compares two major reference energy standards, ASHRAE 90.1 (2013) and NECB 2015. Additionally, this notice provides guidance to States on these processes and associated certifications. Comparing ASHRAE 90.1 2013 and Canada NECB 2015. If this determination is finalized, each State would be required by statute to certify that it has reviewed the provisions of its residential building code regarding energy efficiency, and made a determination as to whether to update their code to meet or exceed the 2015 IECC. DOE analysis indicates that buildings meeting the 2015 IECC (as compared with buildings meeting the 2012 IECC) would result in national source energy savings of approximately 1.03 percent, site energy savings of approximately 1.12 percent, and energy cost savings of approximately 0.90 percent of residential building energy consumption, as regulated by the IECC. Department of Energy (DOE) has preliminarily determined that the 2015 edition of the International Energy Conservation Code (IECC) would improve energy efficiency in buildings subject to the code compared to the 2012 edition. Additionally, this notice provides guidance to States on certifications and requests for extensions of deadlines for certification statements.ĭownload the ?Notice of Determination? here: Upon publication of this affirmative determination, States are required to certify that they have reviewed the provisions of their commercial building code regarding energy efficiency, and, as necessary, updated their codes to meet or exceed Standard 90.1-2013. DOE has determined that buildings built to Standard 90.1-2013, as compared with buildings built to Standard 90.1-2010, would result in national source energy savings of approximately 8.5 percent and site energy savings of approximately 7.6 percent of commercial building energy consumption. Department of Energy (DOE) has determined that the 2013 edition of the ANSI/ASHRAE/IES1 Standard 90.1: Energy Standard for Buildings, Except Low-Rise Residential Buildings would improve energy efficiency in buildings subject to the code compared to the 2010 edition of Standard 90.1.
