Which statement best describes minimum ventilation rates in ASHRAE Standard 62.1-2022?

Which statement best describes minimum ventilation rates in ASHRAE Standard 62.1-2022?

• A. They are optional if occupants are satisfied with comfort.
• B. They are the baseline outdoor air quantities required to achieve acceptable IAQ and limit health effects.
• C. They apply only to energy efficiency.
• D. They apply only to laboratory spaces.

Answer: (B)

Minimum ventilation rates in ASHRAE 62.1-2022 establish the baseline amount of outdoor air that must be supplied to a space to dilute indoor pollutants and protect occupant health. They are a requirement, not optional, and set the floor for how much outdoor air must be delivered to achieve acceptable indoor air quality and limit health effects. These rates are not about energy efficiency primarily, and they apply to a wide range of space types, not just laboratories. The standard provides methods to demonstrate compliance, but the concept remains: outdoor air at these minimum quantities is the baseline you must meet to maintain IAQ.
