The Revision of Standard 62: What a Difference a Decade Makes



Andrew K. Persily


The American Society of heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has been revising Standard 62,Ventilation for Acceptable Indoor Air Quality since 1991. The two primary motivations for this revision have been 1) to convert the document into minimum requirements in mandatory and enforceable language for adoption into building codes and 2) to update the content to reflect the increased knowledge from research and practical experience since the bulk ofthe standard was last approved in 1989. A number of changes have been approved since the revision process began ten years ago, but many difficult issues remain. This paper provides a summary of the progress that has been made to date and the issues that remain to be resolved before a complete code-language version of the standard can be issued.
