ANSI/ASHRAE Standard 62.1-2004 is the latest edition of Standard 62, which has been given the new designation of 62.1 to distinguish it from ASHRAE Standard 62.2-2004, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings. The 2004 edition combines Standard 62-2001 and the seventeen approved and published addenda to the 2001 edition, thereby providing an easy-to-use consolidated standard. Specific information on the contents of each addendum and its approval dates are included in informative Appendix H at the end of this standard.

The purpose of this standard is to specify minimum ventilation rates and indoor air quality that will be acceptable to human occupants and are intended to minimize the potential for adverse health effects. This standard is intended for regulatory application to new buildings, additions to existing buildings, and those changes to existing buildings that are identified in the body of the standard. This standard is intended to be used to guide the improvement of indoor air quality in existing buildings.

This standard applies to all indoor or enclosed spaces that people may occupy, except where other applicable standards and requirements dictate larger amounts of ventilation than this standard. Release of moisture in residential kitchens and bathrooms, locker rooms, and swimming pools are included in the scope of this standard. Additional requirements for laboratory, industrial, and other spaces may be dictated by workplace and other standards, as well as by the processes occurring within the space. Although the standard may be applied to both new and existing buildings, the provisions of this standard are not intended to be applied retroactively when the standard is used as a mandatory regulation or code. This standard considers chemical, physical, and biological contaminants that can affect air quality. Thermal comfort requirements are not included in this standard.
