Status of the Revision of ASHRAE Standard 62



Andrew K. Persily


The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is in the process of revising Standard 62 Ventilation for Acceptable Indoor Air Quality. Because Standard 62 has been designated as a high profile standard by ASHRAE, the revision will result in three separate documents; a code-intended standard, a users manual, and a guideline containing additional information that is not appropriate for the standard. The committee's efforts are currently focused on converting the current version of Standard 62 into a code-intended standard that will be suitable for adoption into building codes, that is, it will contain only minimum requirements intended to protect public health, safety and welfare. The revision of the standard is taking place through the continuous maintenance process, in which incremental changes or addenda to the standard are developed and approved separately. The Users Manual will be a companion document to the standard, and will include the background and rationale behind the requirements in the standard and examples of their application. The third piece of the revision effort is a guideline that will contain information on building and system design, installation, operation and maintenance relevant to ventilation and indoor air quality. This information will be in the guideline rather than the standard because it may not be at a level of practicality or cost that is suitable for all buildings, and therefore not appropriate for the minimum requirements. This paper provides a summary of the current status of the revision process.
