Changes proposed for Standard 90.1
Public input to help shape the technical requirements in Standard 90.1 is being sought through 21 proposed addenda, which could become part of the 2010 standard.
ANSI/ASHRAE/IESNA Standard 90.1-2007 , Energy Standard for Buildings Except Low-Rise Residential Buildings, provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings. The proposed addenda cover a range of topic areas, including daylighting, air leakage, EER and IEER values, and requirements for VRF air conditioners and heat pumps.
If no comments are received on the addenda, they likely will be incorporated into the 2010 version of the standard slated to be published this fall. If comments are received, the substance and volume of those comments will determine whether they are incorporated into the 2010 standard.
The proposed addenda to ASHRAE/IESNA Standard 90.1 are available for comment only during their public review period.
