System balance reports _____.

System balance reports _____.

• A. are not required when systems are designed by a mechanical engineer
• B. must be approved by the Minnesota Pollution Control Agency
• C. shall verify system performance and shall specify that the minimum amounts of outside air is provided
• D. shall not be required for commercial kitchen exhaust systems

Answer: (C)

System balance reports document and confirm that the HVAC system delivers the planned airflows and operates as designed, including meeting ventilation requirements. They verify system performance by measuring actual airflow rates, pressures, and damper positions, and they ensure the minimum outdoor air required by the design and ventilation standards is provided to occupied spaces. This makes the requirement that the balance report shall verify performance and specify the minimum outside air a direct and essential part of commissioning. Balancing is typically required regardless of who designed the system, and it applies to many systems beyond just basic heating or cooling, including kitchen exhaust in many cases. Approval by a specific agency is not a universal requirement for balance reports, and commercial kitchen exhaust systems do require balancing to ensure proper capture and safety.
