Objectives

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

3
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

4
The Solution
The symbol for energy efficiency Making it easy
to make a difference
5
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

6
The ENERGY STAR label

• Only one label at the national level
• 31 product categories
• Representing the top 25 in efficiency
• Products either qualify or dont qualify
• Manufacturers test and label their products
• No cost for participation

7
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

8
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

9
Developing an Effective Label

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

10
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

11
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

12
Why ENERGY STAR Works

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

13
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
• ENERGY STAR makes it easy to make a difference in
  protecting the environment while saving money

14
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

15
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

16
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

17
Recap of October Meeting

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

18
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

19
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

20
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 32F and below 40F.
• Commercial Freezer A reach-in cabinet designed
  for storing food or other perishable items at
  temperatures below 0F and above -5F.

21
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 32F and below 40F
  and at least one of which is designed for storing
  food or other perishable items at temperatures
  below 0F and above -5F.
• Ice Cream Freezer A commercial cabinet designed
  for storing food or other perishable items at
  temperatures below -5F.

22
Definitions (continued)

• Energy Consumption The energy required to
  maintain the contents at a specified temperature
  for a 24-hour period.
