## Impetus for Clothes Washer Criteria Discussion

- On January 1, 2007, the Federal standard will increase to a minimum Modified Energy Factor (MEF) of 1.26 from the current minimum MEF of 1.04.
- Discussions are necessary to insure that the criteria will:
- Provide differentiation between ENERGY STAR qualified products and products just meeting the Federal standard.
- Provide an economic incentive for consumers, utilities, and other stakeholders to invest in the ENERGY STAR program.
- DOE also wants to examine ways that the ENERGY STAR clothes washer criteria might provide significant water savings.

## MEF – Increasing Average

| Date | Average MEF | Number of Qualified Products Above Average |
| --- | --- | --- |
| January 1, 2001 | 1.65 | 23 |
| January 1, 2002 | 1.65 | 33 |
| January 1, 2003 | 1.70 | 38 |
| January 1, 2004 | 1.74 | 45 |
| June 30, 2004 | 1.73 | 77 |
| August 20, 2004 | 1.74 | 81 |

## MEF – Decreasing Savings

| Date of Standard and Criteria | Average Energy Use Federally Qualified Model | Average Energy Use ENERGY STAR Qualified Model | Savings of ENERGY STAR Qualified Model |
| --- | --- | --- | --- |
| January 1, 2001 | 829 kWh/year | 297 kWh/year | 532 kWh/year |
| January 1, 2004 | 615 kWh/year | 254 kWh/year | 361 kWh/year |
| January 1, 2007 | 430 kWh/year | To Be Determined | To Be Determined |

## MEF – Qualified Models at Various Levels

| Minimum MEF | Number of Qualified Products Available* |
| --- | --- |
| 1.42 | 181 |
| 1.55 | 125 |
| 1.60 | 120 |
| 1.65 | 110 |
| 1.70 | 94 |
| 1.71 | 92 |
| 1.75 | 80 |
| 1.80 | 72 |
| 2.00 | 27 |

## Water Factor Issue

- Currently neither the Federal standard nor the ENERGY STAR clothes washer criteria contain any limits on water consumption.
- Although there is a correlation between an increase in MEF and a decrease in water consumption, there are exceptions.
- 16 current ENERGY STAR qualified clothes washers actually use more water per year than the average non-qualified clothes washer.
- States and water utilities are hesitant to promote ENERGY STAR qualified clothes washers without guaranteed water savings.

## Qualified Products Available  - Scenarios

|  | None | 9.5 | 8.5 | 7.5 | 6.5 | 5.5 |
| --- | --- | --- | --- | --- | --- | --- |
| 1.42 | 181 | 144 | 102 | 76 | 63 | 50 |
| 1.60 | 120 | 113 | 91 | 72 | 63 | 50 |
| 1.70 | 94 | 87 | 76 | 64 | 56 | 45 |
| 1.71 | 92 | 85 | 74 | 62 | 54 | 43 |
| 1.80 | 72 | 69 | 66 | 58 | 51 | 42 |
| 2.00 | 27 | 27 | 26 | 26 | 23 | 21 |

## Potential Energy Savings

| MEF | ENERGY STAR Shipments (20% penetration) | Average Energy Use Federally Qualified Model | Average Energy Use ENERGY STAR Qualified Model | Savings of ENERGY STAR Qualified Model | National Aggregate Savings (MWh/yr) |
| --- | --- | --- | --- | --- | --- |
| 1.6 | 1,629,160 | 430 kWh/yr | 219 kWh/yr | 211 kWh/yr | 343,753 |
| 1.7 | 1,629,160 | 430 kWh/yr | 208 kWh/yr | 222 kWh/yr | 361,674 |
| 1.8 | 1,629,160 | 430 kWh/yr | 201 kWh/yr | 229 kWh/yr | 373,078 |

## Potential Water Savings

| Max WF | ENERGY STAR Shipments (20% penetration) | Average Water Use Federally Qualified Model (gallons per year) | Average Water Use ENERGY STAR Qualified Model (gallons per year) | Savings of ENERGY STAR Qualified Model (gallons per year) | National Aggregate Savings (gallons per year) |
| --- | --- | --- | --- | --- | --- |
| 9.5 | 1,629,160 | 14,468 | 10,055 | 4,413 | 7.2 billion |
| 8.5 | 1,629,160 | 14,468 | 8,996 | 5,472 | 8.9 billion |

## Discussion

- The upcoming January 1, 2007 Federal standard change for clothes washers necessitates a reexamination of the ENERGY STAR clothes washer criteria.
- DOE welcomes comments about MEF levels and/or water factor today and by September 17, 2004.
