Commercial Clothes Washer Measure Overview

• Current Category: Proven

• Current Status: Active

• Current Sunset Date: March 31, 2015

• Reason for Update/Review: Current workbook includes one market segment - commercial laundromats.

Snohomish County PUD requested if coin-operated machines in multi-

family common areas could be added to the measure workbook.

Measure Descriptions

• Go to the following sections in the Summary tab in the proposed measure workbook:– Measure Properties– Measure Identifiers

4

Summary of Updates• Reviewed current workbook to see which parameters in

analysis could change between the two market segments.

• Determined that two parameters could be affected:– Washer cycles per day

– Lifetime (EUL)

• Looked at current DOE Technical Support Document (TSD) for commercial clothes washers1, and found that the TSD provides estimates of cycles/day and EUL for both laundromats and coin-operated multi-family machines separately (see next slide).

Remaining Issues for RTF Discussion

• No factors identified.

7

Summary of Changes

• All savings, costs, and cost-effectiveness remain unchanged for laundry measures.

• Costs are assumed to be constant between laundry and multi-family common area units.

• Annual savings for multi-family are less than laundromats, given the relative reduction in cycles per day (3.4 versus 6, respectively)

• Go to the Presentation tab in the proposed measure workbook for graphs of savings, cost, and TRC B/Cs.
