DOE Issues Model Energy Code
Determination for ASHRAE/IES
Standard 90.1-2022
ATLANTA-ASHRAE received in March a determination
issued by the U.S. Department of Energy (DOE) stating
that ANSI/ASHRAE/IES Standard 90.1-2022, Energy
Standard for Sites and Buildings Except Low-Rise Residential
Buildings, will increase energy efficiency in commercial
buildings subject to the code.
The standard achieved this determination
through the DOE's technical analysis estimating that
buildings meeting Standard 90.1-2022 (as compared
to the previous 2019 edition) would result in a national
average site energy estimated savings increase from
9.8% to 14% (referenced as " net " savings).
" With the intensified demand for decreased energy
consumption and carbon reductions in existing
buildings, Standard 90.1 continues to offer essential
guidance in shaping building regulations and amplified
energy legislation, " said 2023-24 ASHRAE President
Ginger Scoggins, P.E., Fellow ASHRAE.
" The DOE's latest determination further solidifies
Standard 90.1 as the cornerstone for achieving energy
efficiency goals and ultimately moves us closer towards
widescale, global building decarbonization of the built
environment. "
The following are DOE's estimates of national savings
in commercial buildings:
* 9.8% site energy savings;
* 9.4% source energy savings; and
* 9.3% carbon emissions savings.
Standard 90.1-2022 marks the first time on-site
generation of renewable energy systems is incorporated
as a prescriptive requirement of the standard,
recognizing the role of renewables in new construction,
echoing similar requirements in several state and local
building codes and better positioning new commercial
buildings to achieve net zero energy in the future. Other
key changes include customizable energy credits, a
new mechanical system efficiency performance option,
requirements to address thermal bridging, expanded
criteria for whole-building air-leakage testing, updated
lighting power allowances and additional guidance for
using emissions in addition to traditional site, source
and cost-based metrics.
States are required to certify within two years of DOE's
affirmative determination that the provisions of its
commercial building code regarding energy efficiency
have been reviewed and, as necessary, updated codes to
meet or exceed the updated edition of Standard 90.1.
