ASHRAE announced that it is seeking public input into a proposed revision of its residential IAQ guideline. ASHRAE Guideline 24-2008, Ventilation and Indoor Air Quality in Low-Rise Residential Buildings, is the companion guideline to ANSI/ASHRAE Standard 62.2-2007, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings. 

Recognizing that the ventilation rate procedure in its IAQ standard may be difficult to apply in existing buildings, ASHRAE is proposing an alternate compliance path. Proposed addendum b is one of six addenda to ANSI/ASHRAE Standard 62.1-2013, Ventilation for Acceptable Indoor Air Quality, open for public comment until Oct. 5, 2014.

While contractors may not yet feel the effects of these changes, they will in the future, which is why they should familiarize themselves with the new version of Standard 62.2.

ASHRAE has announced a proposed change to Standard 62.2 that would place all residential dwelling unit IAQ requirements under that standard in order to provide consistency of ventilation requirements.

ACCA has published a new technical bulletin entitled “Ensuring ASHRAE 62.2-2013 Ventilation Compliance for Residential Structures.”
