Commercial Clothes Washers UES Ryan Firestone Regional Technical Forum April 14, 2015

Overview Today, we are seeking a decision from the RTF on the updated Commercial Clothes Washers analysis. Updated energy savings Updated costs Consider a non-ENERGY STAR front-load measure 2

Measure Identifiers Business type: Multi-family common area, Laundromat DHW fuel type: Electric, Gas Dryer fuel type: Electric, Gas Propose adding “Any” DHW and Dryer fuel type for Multi-family Efficiency level: Currently only an ENERGY STAR measure, propose adding a non-ENERGY STAR front-loader measure 4

Updates to Measure 5 UpdatesCurrent (RTF v.3.0)Proposed Current Practice Front/Top Load mix CEC Appliance DB mix (43% Top Load) DOE findings (2013 market data, extrapolated to 2015) (72% top load) DHW energy Hot water volume a function of tub volume, water factor. 80°F temperature increase in tank Hot water energy imputed from MEF, RMC, and assumption about machine energy. 75°F temperature increase in tank Dryer energy 0.5 kWh/lb moisture, as assumed in the DOE Test Procedure rated RMC 0.62 kWh/lb moisture, as found in the NEEA field study RMC adjusted to reflect NEEA field study Usage Laundromats: 2,190 cycles/year Multi-family: 1,241 cycles/year (DOE 2010 Technical Support Document) Laundromats: 1,497 cycles/year Multi-family: 1,095 cycles/year (DOE 2014 Technical Support Document) Measure costs2010 DOE Technical Support Document2014 DOE Technical Support Document Detergent Non-energy Benefit Detergent cost proportional to water use Remove NEB. Orginal and HE detergents have similar cost per load. No data to support behavioral assumption. Inclusion of non-ENERGY STAR front loader Inclusion of "any"- DHW and dryer fuel type for Multi-Family common area

Current Practice Current RTF measure uses CEC Appliance DB Proposed measure uses DOE Technical Support Document All else held constant 6 Current (v3.0)ProposedMEF kWh/yr, Multi- family kWh/yr, Laundromat Top non-ENERGY STAR43%72%1.672,3633,667 ENERGY STAR0% Front non-ENERGY STAR0%4%2.001,9763,066 ENERGY STAR57%25%2.411,6382,542 Weighted average Annual Energy, Multi-family 1,9492,169 < This illustrates the difference in savings estimates from the change in baseline top/front mix assumption.

Disaggregating Energy Use Total Energy (DOE Test Procedure): [Tub Volume] / [MEF] Machine Energy: DOE found to be small, and fairly constant across machines (~0.1 kWh/cycle) Dryer Energy: DOE Test Procedure value is a function of remaining moisture content (RMC). – NEEA field study found that real-world clothing comes out of washer wetter (~35 percentage points) than DOE test cloth – NEEA field study found that dryers use more energy to remove moisture (0.62 kWh/lb moisture) than DOE test procedure assumes (0.5 kWh/lb moisture) Hot Water Energy: [Total Energy (DOE Test Procedure)] – [Machine Energy] – [Dryer Energy(DOE Test Procedure)] 7

Adding a non-ENERGY STAR front load measure Current Practice: – 72% of market is top-load (MEF ~1.7) – Current Practice MEF 1.87 Front load: – Federal standard MEF 2.0 – ENERGY STAR MEF 2.2 – One product in CEC Appliance DB was front-load, non-ENERGY STAR. Propose adding a MEF 2.00 to 2.19 measure 8

“Any” DHW and Dryer Fuels Measure RTF Implementers Group has expressed interest in “Any” fuels measures Multi-family: RBSA Multi-Family Common Space database provides needed data: – 87% of dryers are electric – 74% of washers are served by electric hot water Laundromat: Haven’t found any data Propose adding an “Any” fuels measure for Multi- family, but not for Laundromat – Should programs be limited to using either specific fuel type measures or “any”, but not both? 9

Savings 10 Savings have increased, primarily because of 1)More top-loaders in baseline 2)Different analysis of hot water energy And countered by 1) Reduced cycles per year

Capital Cost 11 Costs have increased, primarily because of more top-loaders in baseline (i.e., baseline cost is less)

12 Cost Effectiveness Cost effectiveness has gone down, primarily because of the removal of the detergent non-energy benefit

Proposed Motion “I _________ move that the RTF approve the updates to the Commercial Clothes Washers UES measure as presented. Keep the Category at ‘Proven’ Keep the Status at ‘Active’ Set the sunset date to December 31, 2017” 13 New federal standard effective January 1, 2018
