BUILDING ENERGY Washington State 7 <br /> TOTAL SYSTEM TSPR Analysis <br /> . PERFORMANCE <br /> RATIO <br /> U.S. DEPARTMENT OF ENERGY HVAC System Parameter Notes <br /> Building ID#: 25671 Gross Floor Area - Building: 2,790 ft2 <br /> Reported HVAC system parameters are based on the average of the equipment serving each block as follows: <br /> • For DX cooling systems, the cooling COP excludes the fan energy and is calculated' by cooling capacity. <br /> • For heat pumps, the heating COP excludes the fan energy and is calculated' by heating capacity. <br /> • Total System Fan Power is the input electric power for all fans in required to operate at fan system design conditions divided <br /> by the supply airflow rate. Where multiple fan systems serve a single block fan power is based on calculated' average using <br /> on supply air cfm. <br /> • The minimum airflow ratio is the average minimum damper position for all systems serving the block, calculated' by cfm. <br /> This value is a weighted average of design water flor rate,design air flow rate or design heating or cooling capacity of the assigned mechanical equipment schedule entries,as applicable. <br />
