The 2013 version of ASHRAE's indoor air quality standard contains several revisions to help users better meet its requirements. Newly published, "ANSI/ASHRAE Standard 62.1-2013, Ventilation for Acceptable Indoor Air Quality" sets minimum ventilation rates and other requirements for commercial and institutional buildings. The 2013 standard combines the 2010 standard and 10 published addenda to that edition, providing an easy-to-use consolidated standard. Specific information on the contents of each addendum and approval dates for each are included in Informative Appendix J at the end of the standard.
