What is the primary objective of the ventilation rate procedure (VRP)?

• A. Minimize energy use
• B. Deliver desired breathing zone outdoor air
• C. Maximize outdoor air regardless of occupancy
• D. Maintain constant zone temperatures

Answer: (B)

The ventilation rate procedure is about providing the right amount of outdoor air to the breathing zone to meet the minimum ventilation requirements for occupants. It determines how much outdoor air must be supplied to a space so that the air in the zone is properly diluted and refreshed according to the standard. This approach focuses on meeting IAQ needs rather than maximizing outdoor air, maintaining a constant temperature, or merely minimizing energy use. Energy efficiency can be a consideration, but the primary aim of the VRP is delivering the prescribed breathing-zone outdoor air to achieve adequate ventilation.
