allowed to default to 1.0. The UNIT-NA~lE is omitted as it is for userconvenience only in identifying the unit size. Annual costs and overhaulcosts are assumed to be zero. The lifetime of the tank is unspecified andtherefore will default to 999 years. Therefore, no replacements costs willbe calcul ated.The pump has a purchase price of $1000, costs $100 to install, has anannual maintenance cost of $100, and will last 10 years. It requires a minoroverhaul every two years costing $200.2. BASEL! NEThis instruction is used to specify the baseline condition against whichan alternative energy conservation project can be evaluated. The baselinefigures may have been obtained from a previous DOE-2 run, or they may be basedon actual operating data for the building under consideration. In eithercase, the ECONOMICS program compares the calculated life-cycle costs of thepresent run with the baseline figures, to arrive at a dollar and energysavings relative to the baseline case. From this comparison, the programcalculates the statistics described in Sec. A that provide a measure of theinvestment cost effectiveness of the energy conservation alternative underconsideration.The User Worksheet for the BASELINE instruction is reproduced on the nextpage.BASELINEU-nameFIRST-COSTREPLACE-COSTThis command word tells the EDL Processor that data definingthe baseline or reference case follow.is any unique user-defined name that may be entered toidentify this instruction, but none is required.specifies, in dollars, the total baseline initial costs,including installation. If the baseline is an existing,unmodified building, the value of FIRST-COST should be zero.specifies, in dollars, the present value of the life-cyclebaseline replacement cost for plant and nonplant components.OPERATIONS-COST specifies a list, up to 25 values, of baseline operationscosts (present value, in dollars) for each year of the projectlife. If the project life is N years (as specified in PDL)then N values of operations costs must be given sequentiallyfor years 1, 2, ... , N.VI.9 (Revised 5/81)
