The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) publishes thousands of standards for the design and maintenance of indoor environments.
For energy-efficient building design, ASHRAE’s latest version of 90.1 is the 10th edition published since the original standard was first published in 1975 during the energy crisis of the United States. Standard 90.1 provides the minimum requirements for energy-efficient design of most buildings, except low-rise residential buildings. It offers, in detail, the minimum energy efficiency requirements for 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 criteria for determining compliance with these requirements.
According to Department of Energy (DOE) analysis, buildings meeting 90.1-2016 (as compared to the previous 2013 edition) would result in national energy cost savings of approximately 8.2 percent, as regulated by the model code.
The follow are DOE’s energy conservation estimates of national savings in commercial buildings:

As compared to the previous 2013 edition, some of the mechanical-related standard changes include:
The Zero Code
In June 2018, Architecture 2030 released ZERO Code, a building energy standard for new building construction that includes both energy efficiency standards and renewable energy sources to create buildings that release net-zero carbon. The ZERO Code includes potential paths for efficiency compliance, as well as an energy calculator that makes it easier to crunch the numbers. According to Architecture 2030, part of the ZERO Code’s strength is that it builds on existing standards to make it easier for architects to measure: The ZERO Code uses the current national building energy code standard, ASHRAE 90.1-2016, for building energy efficiency and then adds on-site and/or off-site renewable energy procurement to achieve net-zero carbon.
