In an announcement in the May 13 edition of ‘The Federal Register,” DOE attributes the greater energy savings to improvements in ANSI/ASHRAE/IES Standard 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings, related to better lighting, fans, commercial refrigeration, boilers and controls.
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:
ASHRAE, founded in 1894, is a global society advancing human well-being through sustainable technology for the built environment. The Society and its more than 50,000 members worldwide focus on building systems, energy efficiency, indoor air quality, refrigeration and sustainability. Through research, standards writing, publishing, certification and continuing education, ASHRAE shapes tomorrow’s built environment today. More information can be found at www.ashrae.org/news.
