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 –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 , “Method of Testing Closed Refrigerators” Solid-door refrigerator:initial product temp. 38   1  F maximum product temp. 40  F Solid-door freezer:initial product temp. 0   1  F maximum product temp. 2  F Ice cream cabinet:initial product temp. -5   1  F maximum product temp. 0  F

Energy-Efficiency Specs V = Internal volume in ft 3 AV = Adjusted volume (1.63  freezer volume in ft 3 ) + refrigerator volume in ft 3 * Derived from data contained in the CEC data base as of February 2001.
