U.S. ASHRAE received a final resolution issued by the Building Energy Codes Program of the Department of Energy (DOE), which states that the ANSI / ASHRAE / IES 90.1-2016 Standard (Energy Efficiency Standard for Buildings Except Low-rise Residential Buildings) , achieve greater energy efficiency in buildings subject to the code. The 90.1-2016 standard was published in October by 2016.
The standard achieved this determination through the DOE analysis that indicates that buildings that meet the 90.1-2016 standard (compared to the previous edition of 2013) would generate savings in the national energy cost of approximately 8.2 percent, as regulated by the model code.
"The 90.1 standard has been a reliable source of guidance on energy efficiency requirements for professionals in the built environment for more than 40 years," says Bjarne W. Olesen, president of ASHRAE 2017-2018. "The DOE's final determination serves to reinforce the 90.1's reputation as the energy efficiency standard for commercial buildings in the US."
The following are the DOE calculations of national savings in commercial buildings:
8,3% energy savings
7.9% energy saving source
6.8% energy savings on site
This 2016 version of 90.1 is the tenth edition published since the original standard was first published in 1975 during the United States energy crisis. The 90.1 Standard provides the minimum requirements for the energy efficiency design of most buildings, except for low-rise residential buildings. It offers, in detail, the minimum energy efficiency requirements for the design and construction of new buildings and their systems, new portions of buildings and their systems, and new systems and equipment in existing buildings, as well as the criteria for determining compliance with these requirements.
States must certify that the provisions of their commercial building code have been reviewed with respect to energy efficiency and, as necessary, updated codes to meet or exceed the updated edition of the 90.1 Standard.
