PA TRM June 2010, coincident demand factor and Time Period Allocation Factors for ENERGY STAR Room AC. Measure Life Room Air Conditioner Retirement = 4 years From the PA TRM, the EUL for an ENERGY STAR Room Air Conditioner is 10 years, but the TRM does not provide an RUL for RACs. However, as shown in Table 224, the results from a recent evaluation of appliance recycling program found a median age of 21 to 25 years for ComEd’s recycled ACs. For a unit this old, the expected life of the savings is likely to be short, so 4 years was chosen as a reasonable assumption based on these references: DEER database, presents several values for EUL/RUL for room AC recycling: DEER 0607 recommendation: EUL=9, RUL=1/3 of EUL = 3 years. The 1/3 was defined as a but no basis given. “reasonable estimate”, 2005 DEER: EUL=15, did not have recycling RUL Appliance Magazine and ENERGY STAR calculator: EUL=9 years CA IOUs: EUL=15, RUL=5 to 7 With the Old, in With the New: Why Refrigerator and Room Air Conditioner “Out Programs Should Target Replacement to Maximize Energy National Resources Savings,” Defense Council, November 2001, page 21, 5 years stated as a credible estimate.
