ASHRAE standard gains 30% energy savings over 2004 version
Requirements in a 2013 revision of an energy standard will result in buildings that could achieve 6% to 8% more efficiency than buildings built to the 2010 standard, according to ASHRAE and IES.
Published in October 2013, ANSI/ASHRAE/IES Standard 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings, provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings.
