DOE Takes First Step in Updating National Reference Standard for Commercial Buildings to 90.1-2013

Repost from Lightsearch.com

untitledPreliminary analysis from the U.S. Department of Energy shows that the ASHRAE/IES’s 2013 energy efficiency standard contains energy savings over the 2010 standard of 8.5% source energy and 7.6% site energy. This is the first step by the DOE in issuing a ruling that could establish the 2013 standard as the commercial building reference standard for state building energy codes.

In an announcement in the May 13, 2014 edition of The Federal Register, DOE attributes the greater energy savings to improvements in ANSI/ASHRAE/IES Standard 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings, related to better lighting, fans, commercial refrigeration, boilers and controls.

If the preliminary determination is finalized, then states would be required to update their codes to meet or exceed the 2013 standard. Currently, states must meet or exceed the 2010 standard, which serves as the commercial building reference standard for state building energy codes under the federal Energy Conservation and Production Act.

Lighting changes to the 2010 standard include control requirements for lighting alterations, more controls in more spaces and reduction of time to reduction or shut off of those controls, and reduction of lighting power density in most building types.
