ATLANTA - The American National Standards Institute (ANSI) Board of Standards Review has denied an appeal for an addendum to American Society of Heating, Refrigerating, and Air-Conditioning Engineers' (ASHRAE) Standard 62-2001.
The standard, "Ventilation for Acceptable Indoor Air Quality," sets minimum ventilation rates and other requirements for commercial and institutional buildings. The ANSI denial upholds Addendum 62n, which revises the procedure used to determine design ventilation rates. "The procedure now is more straightforward, allowing designers to determine rates and reduce the potential for overventilation in some densely occupied spaces," according to David Butler, P.E., committee chair. Furthermore, he said, the standard is now focused on minimum requirements. The addendum was approved for publication at the society's 2003 annual meeting. Six appeals were filed and later denied by ASHRAE. On May 20, the ANSI Board of Standards Review announced that it voted to deny all appeals made to that organization, thereby upholding its earlier approval of the addendum.
