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

CAT Review Ryan Firestone

Tech Sub-Com Review [none]

R&E Sub-Com Review [none]

Notes • Measure updated/approved in April, 2013 (laundromat)

• Multi-Family common area measures added February, 2014

• Measure sunset May, 2015• New DOE analysis in support of 2014 rulemaking,

standards effective January, 2018• NEEA field study of residential washers/dryers in

2014

4

Measure Identifiers

• Business type: Multi-family common area, Laundromat

• DHW fuel type: Electric, Gas• Dryer fuel type: Electric, GasPropose 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

5

Updates to MeasureUpdates Current (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 energyHot 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

UsageLaundromats: 2,190 cycles/yearMulti-family: 1,241 cycles/year(DOE 2010 Technical Support Document)

Laundromats: 1,497 cycles/yearMulti-family: 1,095 cycles/year(DOE 2014 Technical Support Document)

Measure costs 2010 DOE Technical Support Document 2014 DOE Technical Support Document

Detergent Non-energy Benefit

Detergent cost proportional to water useRemove 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

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)]

8

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

9

“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?
