The American Society for Heating, Refrigerating and Air-Conditioning (ASHRAE) recently released an updated Standard 170-2021. Seventeen addenda were issued to modify the 2017 edition of the American National Standards Institute/ASHRAE/American Society for Health Care Engineering Standard 170, Ventilation of Health Care Facilities, which became the basis of the new Standard 170-2021. The purpose of this Standard 170 is to define ventilation system design requirements that provide environmental control for comfort, asepsis, and odor in health care facilities.  

Much work was undertaken to align and correlated Standard 170-2021 with Facility Guidelines Institute’s 2018 Guidelines Edition.  Hear from an engineer who chairs the Standard 170-2021, an architect and FGI member who worked with ASHRAE to align the two documents, and an authority having jurisdiction who interprets and enforces both standards.

The new Standard 170-2021 includes: 

  • 3 separate sections – Hospitals, Outpatient and Residential 
  • New glossary definitions 
  • Listing of relevant FGI reference section numbers 
  • Clarification on ventilation requirements for inhalation gases 
  • Join us for a high-level overview of the changes in this new document. 

Learning objectives

  • Describe how the new Standard 170-2021 is organized, and how it correlates with FGI 2018    
  • List important changes and updates within the new Standard 170-2021 
  • Understand what requirements apply when using inhalation gases and/or performing invasive procedures   
  • Understand how the new Standard 170-2021 will be updated to correspond with the soon to be published FGI 2022 Guidelines Edition 

This free course is brought to you through a partnership with The American Society for Heating, Refrigerating and Air-Conditioning (ASHRAE). By registering for this course, you grant AIA permission to share your name and email address with Bromic Heating.
