Changes to ASHRAE 90.1 open for comment

Proposed changes designed to improve the energy efficiency of buildings covered by ASHRAE/IESNA Standard 90.1-2007 are open for public comment. The standard provides minimum requirements for the energy-efficient design of most buildings. Currently, 18 proposed addenda to the standard are open for public review.

Proposed changes designed to improve the energy efficiency of buildings covered by ASHRAE/IESNA Standard 90.1-2007 are open for public comment. The standard provides minimum requirements for the energy-efficient design of most buildings. Currently, 18 proposed addenda to the standard are open for public review.

"As we move toward publication of the 2010 standard, the 90.1 committee is considering many changes to reduce building energy use and cost," said Mick Schwedler, chair of the Standing Standard Project Committee. "The proposed addenda that are out for review move toward our goal of 30% energy cost savings."

Among the proposed addendum out for public review is addendum bh, which would require supply air temperature reset in multiple-zone HVAC systems, and addendum bf, which provides a new requirement for continuous air barriers. Balancing the reset with an increase in fan energy can substantially reduce system energy use, Schwedler said.
