The bhp calculation <br />provides adjustments for special equipment per Table C403.2.11.1(2). <br />In Fan Equipment Schedule below, provide maximum design supply airflow <br />rate (CFM) of all supply fans serving the conditioned space in Fan <br />Fan System Supply <br />Equipment Schedule below. Fan System CFM Total is the supply airflow of <br />the handler design Additional <br />9,210 <br />central air at peak conditions. volumetric air <br />CFM Total <br />flow provided at zone fan terminals, booster fans, or through induction is <br />not included in the supply CFM total. However, the fan power of this <br />equipment is included in the HP and BHP calculations.
