REPORT SS-D - PLANT MONTHLY LOADS SUMMARYIn the DOE-2 program multiple central plants, for serving the HVACsystems in the building, can be simulated. The PLANT-ASSIGNMENT command isused to assign HVAC systems to central plants. In the report shown, theuser-defined name of the plant, CONVENTIONAL, is reported in the title line.The cooling, heating, and electrical energy required by the system(s) andzones served on the plant are reported monthly along with the peak cooling,heating, and electrical loads for the combined systems, and the time ofOccurrence. Note that these peak loads may result from startup after thebuilding has been shut down overnight. Cooling done in SYSTEMS by DX units isnot included here in cooling loads but in electrical loads.1. COOLING ENERGY (millions of Btu) is the sensible and latent monthlycooling required by the HVAC systems from the central plant specified inthe PLANT-ASSIGNMENT command.2. TIME OF MAX gives the day and hour that the maximum cooling load occurs.3. DRY-BULB TEMP and WET-BULB TEMP are the outside dry-bulb and wet-bulbtemperatures during the peak cooling load.4. MAXIMUM COOLING LOAD (thousands of Btu/hr) gives the peak cooling loadfor each month and for the year.5. HEATING ENERGY (millions of Btu) is the total monthly heating required bythe HVAC systems from the specified central plant.5. TIME OF MAX gives the day and hour that the maximum heating load occurs.7. DRY-BULB TEMP and WET-BULB TEMP are the outside dry-bulb and wet-bulbtemperatures during the peak heating load.8. MAXIMUM HEATING LOAD (thousands of Btu/hr) gives the peak heating loadfor each month and for the year.9. ELECTRICAL ENERGY (in kWh) is the monthly electrical requirement forlights and convenience outlets for the building zones served by theplant. In addition, the electrical energy contains the fan energyrequirement for the HVAC system. It does not include the electricalenergy associated with pumps, cooling towers, chillers, and electricalheating. These are reported in the PLANT program.10. MAXIMUM ELEC LOAD (kW) give the monthly peak electrical consumption in aone-hour period for lights and convenience outlets in the building zonesserved by the plant.11. NUMBER OF HOURS and COINCIDENT LOADS are as in report SS-C for the wholeplant.VII.53
