States Raise The Bar On High-Performance Buildings

Article | FacilitiesNet (2014)

The U.S. Department of Energy projects that by the end of 2015, about 25 states, concentrated on the East and West coasts, will have adopted the 2012 version of the International Energy Conservation Code (IECC). This latest version of the IECC heavily references ASHRAE Standard 90.1-2010, a standard that includes several updates to requirements for mechanical, electrical, and lighting systems. The new standards for these systems will raise the bar, contributing significantly to energy savings, as compared to the 2007 90.1 standard.

As of July 9 of this year, all federal projects must be designed to comply with ASHRAE 90.1-2010. In addition, ASHRAE 90.1 has been the referenced energy standard within all LEED rating systems, including the latest release of LEED v4. For the immediate future, projects can be registered under both LEED 2009 and v4; as of June 1, 2015, however, all new projects will need to be registered under the LEED v4 rating system. Due to this interconnection, it is important to compare and analyze the changes within both LEED v4 and ASHRAE 90.1-2010 simultaneously.
