Status of Revisions to ASHRAE Standard 62
Abstract
The American Society of Heating Refrigerating
and Air Conditioning Engineers (ASHRAE) Standard
62- 1989 "Ventilation for Acceptable Indoor air
Quality", adopted in 1989, is widely used by HVAC
engineers to determine ventilation rates for various
occupancies. This standard has also been cited in
court to help demonstrate compliance with state-of the-
art indoor environmental design.
In August 1996, ASHRAE released for public
review Standard 62-1989R, the highly controversial
proposed revisions to the Standard 62- 1989.
Over 8,000 comments were received on the
proposed revision. Due to the significant number of
concerns expressed by ASHRAE members as well as
others, ASHRAE withdrew the proposed new
standard and placed the current standard in
"continuous maintenance."
As part of the continuous maintenance process
ASHRAE is transforming the current Standard 62-
1989 from a design standard to code ready document.
Furthermore, two code documents will be
produced4ne for low-rise residential buildings and
another for other types of occupancy.
Finally, two new documents, a user's manual
and an IAQ guideline, will be written concurrent with
the code documents. The guideline document is
intended to provide state-of-the-art guidance to
designers while good IAQ practices not appropriate
for codification will be incorporated into the
guideline.
It is likely that many of the provision in
Standard 62-1989R will survive in some manner in
one or more of the new documents to be produced.
This paper will detail some of the more
significant changes that were proposed in Standard
62-1989R and review the current state of standard
development.
