What is the process for compliance when CBECC-Com determines the HVAC system for the proposed building is undersized?

When the simulation has more than 150 hours of unmet load hours, the HVAC system capacities must be manually increased to meet the load. Remember to increase both airflow and coil capacities. There is an exceptional condition that should be marked “Yes” when this is done, and a note will be added to the compliance report.
