## Presentation Outline

- Market status and review of current specification
- Revision options under consideration
- Next steps and timeline

## Market Snapshot

- 2003 shipments of dehumidifiers approximately 1,311,039 units*
- 2003 installed base approximately 11,308,000 units**
- On average, estimated 12% growth in annual shipments over past 5 years*
- Annual shipments best approximation of annual installed base
- Over 180 dehumidifier models currently available in market-place***

## Current ENERGY STAR Dehumidifiers Specification

| Product Capacity 
(L/day) | Energy Factor Under Test Conditions (L/kWh) |
| --- | --- |
| L/day < 10 | > 1.20 |
| 10 < L/day < 25 | > 1.30 |
| 25 < L/day < 35 | > 1.50 |
| 36 < L/day < 57 | > 2.25 |

-   Effective January 1, 2001
-   13 manufacturing partners/107 qualified models to-date
-   Qualified models currently between 10% - 23% more efficient than standard models; save about $20/year

## ENERGY STAR Products in the Market-Place

| Product Capacity (L/day) | Number of Qualified Products
 | Number of Manufacturers With Qualified Products | Average Retail Price of Products |
| --- | --- | --- | --- |
| L/day < 10 | 2 | 1 | $130 |
| 10 < L/day < 25 | 81 | 11 | $160 |
| 25 < L/day < 35 | 22 | 9 | $220 |
| 36 < L/day < 57 | 2 | 1 | $1,200 |

- Variety of qualified models readily available at all major retailers
- Several utility programs in place for ENERGY STAR qualified dehumidifiers

## Market Penetration of ENERGY STAR Qualified Dehumidifiers

- Estimated ENERGY STAR market penetration*:
-  0% for L/day < 10
- 76% for 10 _<_ L/day < 25
- 76% for 25 _<_ L/day _<_ 35
- 12% for 36 _<_ L/day _<_ 57
- Dehumidifiers specification has been a success
- Major manufacturers are ENERGY STAR partners
- Time to revise specification
- Differentiation in the market
- Additional savings

## Energy-Efficiency Range of ENERGY STAR Qualified Dehumidifiers 

## Revision Option 1

- Leave energy factors for lowest and highest capacity units unchanged
- Raise energy factors for two middle capacities by 0.3 L/kWh respectively

| Product Capacity 
(L/day) | Option 1 Energy Factor Under Test Conditions (L/kWh) |
| --- | --- |
| L/day < 10 | 1.2 (no change) |
| 10 < L/day < 25 | 1.6 (changed from 1.3) |
| 25 < L/day < 35 | 1.8 (changed from 1.5) |
| 36 < L/day < 57 | 2.25 (no change) |

## Revision Option 2

- Redefine capacities in pints/day
- Add an additional middle capacity level
- Realize inherent increase in efficiency with capacity
- Leave energy factors for lowest and highest capacity units unchanged

| Product Capacity (Pints/day) | Option 1 Energy Factor Under Test Conditions (L/kWh) |
| --- | --- |
| Pints/day < 20 | 1.2 (no change) |
| 20 < Pints/day < 35 | 1.4 |
| 35 < Pints/day < 55 | 1.6 |
| 55 < Pints/day < 75 | 1.8 |
| 75 < Pints/day < 120 | 2.25 (no change) |

## Revision Option 3

- Redefine capacities in pints/day
- Leave energy factors for lowest and highest capacity units unchanged
- Energy factors for middle capacity levels calculated through linear formula; follows inherent relationship between efficiency and capacity

| Product Capacity (Pints/day) | Option 3 Energy Factor Under Test Conditions (L/kWh) |
| --- | --- |
| Pints/day < 20 | 1.2 (no change) |
| 20 < Pints/day < 75 | EF = 1.1 + (Capacity * 0.011)
Capacity in pints/day |
| 75 < Pints/day < 120 | 2.25 (no change) |

## Next Steps: Stakeholder Input

- Want to get feedback on market impacts of these different options
- EPA open to other options
- Things to Think About:
- Should EPA revisit levels for lowest and highest capacity units?
- Only 4 qualified products in these capacities to-date
- Possibly allow more units to qualify by raising the levels?
- Should EPA redefine capacities in pints/day?
- New technologies or product-types that EPA should consider?
