The 2019 version of ASHRAE Standard 62.1, Ventilation for Acceptable Indoor Air Quality, was published in late 2019. This ENL will overview the standard, discuss several key changes implemented in the 2019 version, explain the three allowed procedures for determining ventilation airflows (Ventilation Rate Procedure, IAQ Procedure, and Natural Ventilation Procedure), and walk through calculation steps using an example office building.
- Identify the different sections of Standard 62.1
- Explain key changes implemented in the 2019 version, including a maximum indoor dew point limit and a new Simplified Procedure for designing a multiple-zone recirculating system
- Perform zone- and system-level ventilation calculations required for compliance with the standard’s Ventilation Rate Procedure
- Understand the steps required for compliance with the standard’s IAQ Procedure
Includes agenda, presenter biographies and presentation slides.
