What is the purpose of ASHRAE Standard 62.1-2022?

• A. To specify minimum ventilation rates and measures for acceptable indoor air quality that minimizes adverse health effects.
• B. To regulate energy efficiency of HVAC systems exclusively.
• C. To define occupancy density limits for all types of buildings.
• D. To provide guidelines for acoustic performance of ventilation equipment.

Answer: (A)

The main concept is that ASHRAE Standard 62.1-2022 sets the minimum ventilation rates and indoor air quality measures needed to maintain acceptable IAQ and minimize adverse health effects. It provides the requirements for outdoor air delivery, filtration and contaminant control, and related design criteria so ventilation systems reliably protect occupants. It is not primarily about energy efficiency, occupancy density limits, or acoustic guidelines—those areas are addressed by other standards or aspects of building design.
