ASHRAE's Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings

Standard Scope
AHRI closely follows ASHRAE's Standard 90.1:  Energy Standard for Buildings Except Low-Rise Residential Buildings. Standard 90.1 provides minimum requirements for the design of energy efficient buildings. The first edition of ASHRAE Standard 90.1 was published in 1975 and revisions were approved in 1980, 1989, 1999. Since 1999, the standard has been updated every three years. The 90.1 standard is referenced in the International Energy Conservation Code (IECC) as well as in the National Fire Protection Association (NFPA) 5000 Building Construction and Safety Code. In addition, states are required, under the energy policy act (EPACT) of 1992, to adopt a building energy code as or more stringent than ASHRAE 90.1.

AHRI monitors the status of ASHRAE 90.1 activity throughout all states. Most states adopt ASHRAE 90.1 or the International Energy Conservation Code as their building energy code. However, few states have no energy codes.
