2015 Washington State Ener' .de Compliance Forms for Commercial, R2 a- 73 over 3 stories and all R1 <br /> Mechanical Fan System Power Allowance MECH-FANSYS <br /> 2015 Washington State Energy Code Compliance Forms for Commercial Buildings including R2&R3 over 3 stories and all R1 Revised January 2017 <br /> Project Title: Madison Pub Date 4/3/2017 <br /> A separate MECH-FANSYS form must be completed for every HVAC system that exceeds the 5 hp threshold. For Building Dept. Use <br /> Fan System ID <br /> System Supply Fan Constant Volume(CV), Variable Air <br /> y pp y CV Volume(VAV),or Hospital/Lab CV <br /> Speed Control system that qualifies for VAV budget per <br /> C403.2.11.1,Exception 1 <br /> Compliance is based upon either the fan motor nameplate horse power <br /> Compliance Option Nameplate HP (Option 1), the fan brake horsepower(Option 2),or C403.7 high efficieny <br /> VAV fan brake horsepower(10%less than Option 2). 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 /> Equipment Schedule below.Fan System CFM Total is the supply airflow of <br /> Fan System Supply 2000the central air handler at peak design conditions.Additional volumetric air <br /> CFM Total 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.Fan System <br /> Supply CFM Total is automatically calculated by the form. <br /> Fan Equipment Schedule <br /> Total CFM Total Nameplate Total BHP <br /> Fan ID and Location Fan Type Quantity of Fan Type (Note 1) HP(Note 2) (Note 3) <br /> Unit Supply 1000 2,000 1 1 <br /> Note 1-Total CFM is the maximum CFM of the listed fan(s)when Total Proposed: 1.0 1.0 <br /> operating at peak design operating conditions. <br /> Note 2-Total namplate hp of the listed fan(s). Total Allowance: 2.2 1.9 <br /> Note 3-Total brake horsepower(bhp)of the listed fan(s)at peak <br /> design operating conditions. Not required <br /> if Nameplate HP compliance option chosen. Compliance Message: COMPLIES <br /> Brake Horsepower Allowance Adjustments <br /> Calculated <br /> Assigned Pressure Adjustment, <br /> CFM thorough this Pressure Drop, <br /> Device Type Description and Location Drop,PD in w.c. A in bhp <br /> device(CFMD) (Note 6) PD in w.c. (Note 8) <br /> (Note 7) <br /> Note 4-Bhp allowance for energy recovery devices and run around coil loops includes both air Total Adjustment(bhp): 0.00 <br /> streams,so the CFMD is the sum of the supply CFM and exhaust CFM if both go through <br /> the device. <br /> Note 5-Energy recovery effectiveness is defined as change in the enthalpy of the outdoor air supply <br /> divided by the enthaply difference between the outdoor air and return air at design conditions. <br /> Note 6-Assigned pressure drop(PD)adjustment per Table C403.2.11.1(2). <br /> Note 7-Pressure drop(PD)adjustment shall be calculated per the applicable method <br /> defined in Table C403.2.11.1(2)based on specific system conditions. <br /> Note 8-A=PD*CFMD/4131 where A is the allowed system brake horse power <br /> adjustment,PD is pressure drop allowance,and CFMD is the cfm through the device. <br /> , , ! / <br />
