I am becoming involved with a project that is being designed to reheat more than 30% of the max cooling airflow rate at the VAV box. 

Section 6.5.2 of 90.1 does not allow reheating more than 30% of the zone's design peak supply rate. 

Section 6.5 is prescriptive not mandatory. 

My guess is that the design can reheat more than 30%. Baseline energy model accounts for reheating no more than 30% while the Proposed energy model is accounts for the as-designed building. 

is this correct?
