An Update on ANSI/ASHRAE Standard 62.1

ABSTRACT

Another continuous maintenance cycle for ANSI/ASHRAE Standard 62.1 has concluded, and the keen observer will have already noticed one of the changes made in the 2022 edition of the standard. Despite the conditions created by the COVID-19 pandemic, the committee has continued to meet over the past two years, more often in web conferences than in person, to consider continuous maintenance proposals and interpretation requests and to discuss issues related to ventilation and indoor air quality. The addenda that have been adopted to the 2019 edition of that standard generally fall into three categories clarifications, harmonization and improved procedures. Work was also begun on mandatory air density corrections, further development of humidity control requirements and addressing future extreme events, but this work was not completed in time for inclusion in the 2022 edition of the standard.
