In addition, standards bodies will frequently issue errata or reissue standards over time and governmental bodies may change which standards they incorporate to law. Please note that the process of scanning, OCR, and rekeying might introduce errors. Many of the laws in this collection were re-keyed into HTML and diagrams redrawn for increased usability and accessibility. Note that many of these documents had to be procured on the used marketplace. We posted this document in order to allow citizens to read the laws that govern us.

I will post a more detailed comparison of the 19 versions of ASHRAE 90.1 soon.This document was posted by, which is not affiliated with nor authorized by the United States government, any state government, or the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).

Green Building Council, Standard 189.1, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings, will provide minimum requirements for the design of high-performance new commercial buildings and major renovation projects, addressing energy efficiency, a building’s impact on the atmosphere, sustainable sites, water use efficiency, materials and resources, and indoor environmental quality.ĪSHRAE publishes a revised version of the standard every three years. Being developed in partnership with IESNA and the U.S. In addition, ASHRAE is working on providing more stringent energy guidance in a proposed standard for high-performance buildings.
Ashrae 90.1 standard code#
Nearly half of the states (24) currently have an energy code in place at least as stringent as ASHRAE 90.1-2004, meaning 13 states will likely catch up in 2010 and 13 will not comply for various reasons, such as “home rule” state constitutions. *Lower retail sales lighting power allowance. *Addition of occupancy sensor requirements for classrooms, meeting and lunch rooms. *Revised exterior lighting power density allowances. *Complete replacement of interior lighting power density allowances. Site energy savings are estimated to be approximately 11.9%,” according to the ruling published in The Federal Register.ĭOE noted that the newer version of the standard contained 13 positive impacts on energy efficiency, several of which are related to lighting: “The quantitative analysis of the energy consumption of buildings built to Standard 90.1-2004, as compared with buildings built to Standard 90.1-1999, indicates national source energy savings of approximately 13.9% of commercial building energy consumption. Thirty-seven states complied with the last DOE ruling establishing ASHRAE 90.1-1999 as the national energy standard. If they do not have a code in place at least as stringent as 90.1-2004, they must justify why they can’t comply. ANSI/ASHRAE/IESNA Standard 90.1-2004, Energy Standard for Buildings Except Low-Rise Residential Buildings, has been established by the Department of Energy as the commercial building reference standard for state building energy codes starting in 2010.īy December 30, 2010, all states in the United States must certify that their building codes meet or exceed the requirements in ASHRAE/IESNA’s 2004 energy efficiency standard, under a 12/30/08 ruling.
