ASHRAE has released the 2013 version of its indoor air quality standard, which according to the association, contains several revisions that will help users better meet its requirements. 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 a consolidated standard. Specific information on the contents of each addendum and approval dates for each addendum are included in Informative Appendix J at the end of the standard.
“The 2013 version of Standard 62.1 continues the trend of increasing clarity while adding flexibility,” said Roger Hedrick, Standard 62.1 committee chair. “These changes will allow designers and building operators to meet the requirements of the standard and provide adequate ventilation airflow to occupants while reducing excess ventilation and the associated energy consumption.”
The 2013 edition of the standard revises and improves the standard in several ways. A number of changes remove inconsistencies within the standard and improve clarity. Changes were made to sections of the standard that include requirements for the quality of water used in humidification systems, building level pressurization, a filtration requirement on air entering wetted cooling coils, and much more.
