REPORT PS-A - PLANT ENERGY UTILIZATION SUMMARYThe information in this report is site and source energy use in MBTUs(10 6 Btu). For electrical energy an entry followed by an E is the energy inMWrls (thousands of KWH).1. MONTH2. TOTAL HEAT LOAD. These values are identical to those in the HEATINGENERGY column of the SYSTEMS SS-A report except that the heat energydelivered to an absorption chiller, steam turbine, domestic hot water, andcirculation losses is included, if one has been assigned to the plant.Also included is the heat input to a storage tank from a boiler. Totalheat energy can be described either in terms of the use of that heat or interms of the source of that heat. Thus total heating energy ~ load fromSYSTEMS + load from PLANT (i.e., absorption chillers + steam turbines +heat dissipated from storage tanks + domestic hot water + heat stored intanks but not used) + circulation loop losses. Alternatively, total heatenergy ~ boiler output + recovered heat + solar heat + purchased steam +domestic hot water + loads-not-met.3. TOTAL COOLING LOAD. These are the total of the values shown in the SS-AReport plus the tank and circulation loop losses and represent the coolingenergy needed each month.4. TOTAL ELECTR LOAD. This is the total electrical energy consumed bylights, equipment, and system fans plus the additional energy consumed bychiller motors, pumps, cooling towers, and any other electrical site useincluding energy entered into the program under BUILDING-RESOURCE.5. RECVRED ENERGY. These values are recovered heat used to reduce heatingloads. This is waste heat from turbines, diesels, and double-bundlechillers, and solar energy delivered to the load via HEAT-RECOVERY.6. WASTED RECVRABL ENERGY. The values in this column represent the heat thatcould have been recovered, had there been a need for it, but no needexisted.7. HEAT INPUT COOLING. This column reports the heat energy used to driveabsorption chillers.8. ELEC INPUT COOLING. This column reports the electric energy used to driverefrigeration units and to supply power for peripheral cooling equipment,such as circulation pumps, cooling towers, and cold storage tanks.9. FUEL INPUT HEATING. This column reports the fuel used for heating byboilers, furnaces, and hot water heaters.10. ELEC INPUT HEATING. This column reports the electrical energy used inassociation with supplying heating. This includes the electricalconsumption by draft fans, circulation pumps, electric boilers, and hotwater storage pumps.\VII.96 (Revised 5/81)
