About This Item
Full Description
Standard 62.1 specifies minimum ventilation rates and other measures intended to provide indoor air quality (IAQ) that’s acceptable to human occupants and that minimizes adverse health effects. The standard provides procedures and methods for meeting minimum ventilation and IAQ requirements to engineers, design professionals, owners, and jurisdictional authorities where model codes have been adopted.
Since its original publication, Standard 62.1 has been revised and enhanced in ways that make it more than an air treatment and ventilation standard. To signify that indoor air quality goes beyond minimum ventilation requirements—and in recognition of those aspects of building systems (equipment, filtration, controls, and more) that contribute to acceptable IAQ—the title of the standard has been updated to “Ventilation and Acceptable Indoor Air Quality.”
Standard 62.1 is uniquely qualified to address ventilation and acceptable IAQ in the built environment and will enable stakeholders to make a conscientious effort to improve the indoor environment while maintaining a minimum standard for ventilation. The addenda that compose the 2022 edition of the standard represent years of research, statistical evidence, and improved building systems and technologies:
* Reorganized Section 5, “Systems and Equipment,” to better reflect the path of airflow and illustrate how buildings, systems, and equipment are related
* Continued focus on IAQ, including improvements to the IAQ Procedure, setting maximum dew-point temperatures in mechanically cooled buildings and required exhaust air separation distances
* Added owner acknowledgment of ANSI/ASHRAE Standard 188
* Relocated health-care-related spaces in the scope of ASHRAE/ASHE Standard 170 to a new normative appendix
* Updated definitions, clarified air density adjustments, and removed of items related to transient occupancies that now fall under Standard 62.2
