Content DescriptionStandard 90.1 has been a benchmark for commercial building energy codes in the United States, and a key basis for codes and standards around the world, for almost half a century. This standard provides the minimum requirements for energy-efficient design of most sites and buildings, except low-rise residential buildings. It offers, in detail, the minimum energy efficiency requirements for design and construction of new sites and buildings and their systems, new portions of buildings and their systems, and new systems and equipment in existing buildings, as well as criteria for determining compliance with these requirements. It is an indispensable reference for engineers and other professionals involved in design of buildings, sites, and building systems. The 2022 edition of Standard 90.1 incorporates over 80 addenda to the 2019 edition. Major additions appearing for the first time in a minimum-efficiency U.S. model energy standard or code at the national level include: A minimum prescriptive requirement for on-site renewable energy An optional Mechanical System Performance Path allowing HVAC system efficiency tradeoffs based on the new total system performance ratio (TSPR) metric New requirements to address the impacts of thermal bridging Other highlights include: An expanded scope to include sites as well as buildings New energy credit requirements for a customized approach to improving energy efficiency New informative guidance for using carbon emissions, site energy, or source energy as alternative performance metrics to the current energy cost metric Significant efficiency increases in IEER for commercial rooftops and a new SEER2/HSPF2 metric for <65K sized air-cooled heat pumps.

ASHRAE, founded in 1894, is a building technology society with more than 50,000 members worldwide. The Society and its members focus on building systems, energy efficiency, indoor air quality and sustainability within the industry. Through research, standards writing, publishing and continuing education, ASHRAE shapes tomorrow’s built environment today.
ASHRAE was formed as the American Society of Heating, Refrigerating and Air-Conditioning Engineers by the merger in 1959 of American Society of Heating and Air-Conditioning Engineers (ASHAE) founded in 1894 and The American Society of Refrigerating Engineers (ASRE) founded in 1904.
