Once these input values were determined, they were substituted into the above equation in order to estimate the UEC for removed refrigerators and freezers for each EDC. Table 277 to Table 280 below provide the equation inputs needed to calculate the UEC for removed refrigerators and freezers respectively as well as the calculation of the default Unit Energy Consumption value for refrigerators or freezers for each EDC. Note that equation inputs in Table 277 to Table 280 are provided for each appliance (refrigerators, then freezers) depending on whether the units were or were not replaced with a new unit.
