What does VRP stand for in ASHRAE 62.1?

• A. Ventilation Rate Procedure
• B. Ventilation Risk Protocol
• C. Ventilation Response Plan
• D. Ventilation Regulation Policy

Answer: (A)

Ventilation Rate Procedure is the term used in ASHRAE 62.1 to determine the minimum outdoor air flow required to meet the indoor air quality objectives. It uses space parameters such as the number of occupants and the floor area to apply rate-based requirements, providing a straightforward way to establish ventilation.

This is the best answer because the standard names this method Ventilation Rate Procedure. The other options aren’t used as the official method names in 62.1; they don’t describe how the standard calculates required ventilation rates. (Note: ASHRAE 62.1 also includes an alternative approach called the Indoor Air Quality Procedure, which is a different method for meeting IAQ targets.)
