2015 Washington State E,,-gy Code Compliance Forms for Commercial, R2-.:d R3 over 3 stories and all R1 <br /> ,Mechanical Fan System Power Allowance <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: Everett Community College-Lean Date 7/24/2020 <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 1D DOAS-01 <br /> System Supply Fan Constant Volume(CV), Variable Air <br /> y pp y VAV Volume(VAV),or Hospital/Lab CV <br /> Speed Control system that qualifies for VAV budget <br /> per C403.2.11.1,Exception 1 <br /> Compliance is based upon either the fan motor nameplate horse power <br /> Compliance Option Brake 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 forspecial equipment per Table C403.2.11.1(2). <br /> in Fan Equipment Schedule below,provide maximum design supply <br /> airflow rate(CFM)of all supply fans serving the conditioned space in Fan <br /> Fan System Supply Equipment Schedule below.Fan System CFM Total is the supply airflow of <br /> y pp y 12,000 the 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 /> Supply ERV-Supply 2 12,000 20 14.46 <br /> Exhaust ERV-Exhaust 2 12,000 15 8.16 <br /> Note 1-Total CFM is the maximum CFM of the listed fan(s)when Total Proposed: 35.0 22.6 <br /> operating at peak design operating conditions. <br /> Note 2-Total namplate hp of the listed fan(s).
