## Objectives 

- Describe ENERGY STAR
- Recap October Meeting
- Explain difference between this and California activities
- Review Draft Eligibility Criteria
- Determine Next Steps

## History - The problem

- Consumers invested little in efficient products
- -  Lack of information about energy efficiency benefits
- The most advanced technologies were not well represented in the market
- -  Lack of incentives for manufactures to produce more efficient products
- Political limitations
- -  Manufacturers resisted the implementation of more rigorous standards

## The Solution

**The symbol for energy efficiency**
**Making it easy to make a difference**

## The ENERGY STAR solution

- Voluntary partnership with manufacturers
- Gives the purchaser an easy way to choose efficient products
- Makes link between energy consumption and air pollution
- Facilitates collaboration among EPA, manufacturers, retailers and utilities so as to increase sales of ENERGY STAR labeled products

## The ENERGY STAR label

- Only one label at the national level
- 31 product categories
- Representing the top 25% in efficiency
- Products either qualify or don’t qualify
- Manufacturers test and label their products
- No cost for participation

## ENERGY STAR Products

- Household appliances
- CFLs / residential fixtures / exit signs
- Consumer electronics
- Office equipment
- Heating and cooling equipment
- New homes
- Windows
- Transformers
- Roof products
- Water coolers
- Dehumidifiers
- Traffic signals

## ENERGY STAR - The latest

- Under Development
- Commercial solid door refrigerators and freezers
- Ventilation fans
- Ceiling fans
- Telephony

- Being explored
- Air purifiers
- Motors
- Unitary HVAC
- Vending machines

## Developing an Effective Label

- Energy and environmental analysis
- Market research and design analysis
- Specification development (in cooperation with stakeholders)

## Criteria for Product Selection

- Significant energy savings potential
- Efficiency would be cost-effective
- Performance is maintained or enhanced
- Efficiency can be achieved with non-proprietary technology
- Product differentiation and testing are feasible
- Labeling would be effective in the market

## Supporting the Label

- Publicity and consumer education
- Marketing tools and financing
- Recognition of manufacturer efforts with annual awards
- Strengthening the links within product  distribution networks
- Purchasing tools

## Why ENERGY STAR Works

- Adds value to products & services
- Simple --- consistent platform
- Flexible --- partners can take ownership
- Builds on existing market structures

## ENERGY STAR is Simple

- One program
- Unified web site www.energystar.gov
- Unified Partnership Agreement
- Enhanced brand management
- Unified set of logos
- One promotional message
*E**NERGY** S**TAR makes it easy to make a difference in protecting the environment while saving money*

## Success of ENERGY STAR

- Widespread and growing participation
- More than 1,600 manufacturer partners
- More than 11,000 product models that comply with ENERGY STAR specifications
- 100 companies that provide electricity to nearly 47% of households
- more than 7,100 stores in 50 states and Puerto Rico
- 33 state and local governments require purchase of ENERGY STAR labeled products

## Impact of ENERGY STAR

-  41% of Americans recognize the ENERGY STAR label
-  Improvements in the design and energy efficiency of products
-  530 Million ENERGY STAR labeled products sold (cumulatively) Resulting in:
-  Savings of $28.4 billion over their lifetime
-  Reduction of carbon emissions by 78 million metric tons over their lifetime

## Recap of October Meeting

- Why ENERGY STAR is interested in commercial refrigeration
- Market observations
- Potential for energy savings
- Current activities: CEC, CSA, ACEEE, FSTC
- What a draft specification could be
- Energy use equation
- Solid door units only
- Test according to ASHRAE 117

## Recap of October Meeting

- Action Items
- Examine ASHRAE 117 and address loopholes
- Review product categorization
- Analyze CEC database to derive equations for energy use

## CEC vs. ENERGY STAR

- CEC is setting minimum _standards_ for energy efficiency for many products
- Including commercial refrigeration
- 2 tiers: 75% and 50%
- Mandatory to sell in CA
- ENERGY STAR is voluntary
- Highlights top energy performers (~25%)
- Nationwide program

## Draft Eligibility Criteria

- Product specific information
- Definitions, qualifying products, energy-efficiency specifications, and testing protocol
- One element of the *Partnership Agreement*
- Signed by manufacturer
- Contains standard language
- Partner commitments
- Logo Use Guidelines

## Definitions

**Commercial Refrigeration Cabinet:**  A refrigerator, freezer, or combination refrigerator-freezer for storing food products or other perishable items at specified temperatures and designed for use by commercial or institutional facilities.
**Commercial Refrigerator:**  A cabinet designed for storing food or other perishable items at temperatures above 32°F and below 40°F.
**Commercial Freezer:**  A reach-in cabinet designed for storing food or other perishable items at temperatures below 0°F and above -5°F.

## Definitions (continued)

**Commercial Refrigerator-Freezer:**  A cabinet with two or more compartments, at least one of which is designed for storing food or other perishable items at temperatures above 32°F and below 40°F and at least one of which is designed for storing food or other perishable items at temperatures below 0°F and above -5°F.
**Ice Cream Freezer:**  A commercial cabinet designed for storing food or other perishable items at temperatures below -5°F.

## Definitions (continued)

**Energy Consumption:**  The energy required to maintain the contents at a specified temperature for a 24-hour period.
**Initial Product Temperature:**  The temperature of a test package at the beginning of the performance test.
**Maximum Product Temperature:**  The highest temperature of any test package during the performance test.

## Qualifying Products

**Reach-In Cabinet:**  An upright commercial refrigeration cabinet with one to three solid doors, but not including undercounter, roll-in, roll-through, or pass-through cabinets.
**Undercounter Cabinet:**  An upright commercial refrigeration cabinet with one to three solid doors intended for installation under a counter and is thermally isolated from the counter.

## Qualifying Products (cont’d)

**Roll-in or Roll-through Cabinet:**  An upright commercial refrigeration cabinet with one to three solid doors that allows wheeled racks of product to be rolled into or through the refrigerator or freezer.
**Pass-through Cabinet:**  An upright commercial refrigeration cabinet with one to three solid sliding or hinged doors on both the front and rear of the refrigerator or freezer.

## Test Criteria

- ASHRAE Standard 117-1992,
-  “Method of Testing Closed Refrigerators”
