TO: 

## Association of Home Appliance Manufacturers (Dishwasher Standards Group) On February 28. 1995. The Department provided a preliminary Life Cycle Cost Analysis to the Association of Home Appliance Manufacturers (AHAM). This analysis was provided for the AHAM members that are conducting negotiations regarding the next round of dishwasher standards (Docket No. EE-RM-94-403) with the non-industry group. On March 21, 1995 the negotiating group met in San Francisco to discuss dishwasher standards. The non-industry parties had some questions regarding the analysis. In response. the industry group agreed to submit additional data for clarification. On June 27. 1995 AHAM submitted additional information to the Department for a second round of life cycle cost analysis. The Lawrence Berkeley Laboratory has conducted the second preliminary life cycle cost analyses which are attached for your distribution to all negotiating parties. Ifyou have any questions regarding this material please contact me at (202) 586-8459.

## Methodology Used in Dishwasher Analysis -- July/August 1995
* Cost and Energy Use The cost to implement a design option combination was taken from the most recent data submitted by AHAM. The column labeled "incremental cost perunit" used data as provided by AHAM without combining in any other costs (i.e. reference to the baseline cost and not summed with previous design option costs). Exceptions were made for the lasttwo design options: (1) reduced water inlet and (2) reduced waterinlet with insulation. The costs and energy savings ofthese two options were combined with preceding options (see Adjustments). * Ordering Ingeneral design options were ordered by payback from the AHAM supplied spreadsheet. Options that were not added in combination with others, such as Adaptive Control, are listed separately atthe bottom ofthe table and are not plotted. Where the following design option could branch into several options (such as AHAM option 17a could branch to either 17b or 19a) the path with the lowest payback was chosen unless that option had alower payback. Some design options or design option combinations submitted by AHAM were not used because they hadlower cumulative payback values than othercombinations that included the omitted design option. *
- Adjustments What: Coarse orno filter, AHAM option 19a to 19b, Adjustment to cost andenergy consumption 

# Why: Because ofa difference in number ofrespondents (and alarge variation in prices and estimated energy consumption) an adjustment had tobe made for consistency and reasonableness. The increase in cost foradding a 20% more efficient motor was adjusted to be equal to the same design option change in the fine filtercategory. The energy savings due to adding a 20% efficient motor was also adjusted to be about the same as for the fine filter. The unadjusted value showed too high areduction inmotor energy. Thebaseline motor is assumed to use approximately 0.24 kWh/cycle; therefore a 10% improvement should save about 0.024 kWh/cycle.
