Western Mall Total Energy Plant in Sioux Falls, South Dakota, serves an enclosed mall shopping center of 462,000 ft/sup 2/. The plant provides most of the mall and tenants with electricity, space-heating, and air-conditioning services from a natural gas-fueled engine-generator plant with hot water heat recovery, supplementary gas-fueled boiler, and absorption water chiller. Heating load served by the plant is calculated to be 15,000,000 Btu at -30/sup 0/F winter design condition with 70/sup 0/F space temperature. Maximum observed cooling load at 100/sup 0/F, 75/sup 0/ W.B. outdoor conditions is about 750 tons of refrigeration. Engine heat is recovered in a water system operated at 210 to 240/sup 0/F; an auxiliary scotch marine type, firetype gas-fueled boiler provides up to 14,000,000 Btu/h or supplementary heat. Energy customers have recently begun to exercise considerable control over their uses of electricity with more careful operation of lighting and appliances and with some replacement of illumination devices with more-efficient equipment. It is concluded that central heating and air-conditioning facilities provide the owner with an assured means for serving the shopping center, regardless of which energy source is most economical or least available. The hot and chilled water can be obtained from gas fuel as at present, from fuel oil, propane, all electric, or coal firing. Adapting the conversion equipment is difficult only for coal because of the space requirement for storage and handling that fuel. The power-generating capacity in place is an asset that should be used to serve the tenants because it reduces the public utility company need for expanded capacity. (MCW)
