3. Energy rating:
 A designation of the relative efficiency of an appliance
 An estimate of the comparative annual energy
consumption (kilowatt hours/year)
 It based on the tested energy consumption and
information

4. Energy rating Program:
The Energy Rating Program is implemented by a number
of initiatives i.e. federal, state and government agencies
under the Equipment Energy Efficiency (E3) Program. It
includes different programs:
 Minimum Energy Performance Standards (MEPS)
 Residential Energy Monitoring Program
 Energy rating label
 Climate-based energy efficiency
labeling system

5. WHY ENERGY RATING?
 Electricity consumption and greenhouse gas
emissions.
 To improve the energy efficiency of the products
 So that they uses least energy and meets the
consumers energy service needs.

6. Green house effect:
 Greenhouse gases are a natural part of the
atmosphere. The greenhouse effect is a warming of
Earth's surface and the air above it. It is caused
by gases in the air that trap energy from the sun. These
heat-trapping gases are called greenhouse gases. The
most common greenhouse gases are water vapor,
carbon dioxide, and methane.

7. Main policy tools:
The main policy tools that are used to improve the energy
efficiency of appliances and equipment, in the residential,
commercial and industrial sector, and save money are :
 Mandatory Minimum Energy Performance Standards
(MEPS)
 Mandatory Energy Rating Labels
 Energy star

8. Minimum Energy Performance
Standard:
 MEPS specify the minimum level of energy
performance that product must meet or
exceed before they can be offered for sale
 MEPS specify the energy performance
 The products must be registered online

9. Examples:
 An electric fan is required to shift air at a
specified rate while consuming a limited
amount of power.
 A fluorescent bulb is required to start and run
up to near full brightness in a given time
 storage water heater heats up a specified
quantity of water to a specified temperature

10. Advantages of MEPS:
 Effective way to increase the energy efficiency
of products
 Increase average product efficiency over time
 Prevent inefficient products in market
 Reduces greenhouse gas emissions

11. Disadvantages of MEPS:
 Requires consensus/cooperation among
multiple stakeholders
 Can incur some up-front costs to consumers
 Requires good enforcement policy

12. Energy star:
 Energy Star is a government-backed
labeling program
 It helps people and organizations save money and reduce
greenhouse gas emissions
 In recent years, Energy Star ratings have been extended
to some new homes, commercial and industrial facilities.
 It sets energy performance standards for:
Electronic equipment
Appliances
Buildings & HOME

13. Origin of energy star:
 Energy Star is an international standard for energy
efficient consumers products originated in the United
States. It was created in 1992 by the environmental
protection agency and the department of energy
 Since then, Australia, Canada, Japan, New Zealand,
Taiwan and the European union have adopted the
program

14. what makes a product energy
star?
 ENERGY STAR products are better than standard
products
 To earn the ENERGY STAR they must meet strict
energy efficiency criteria set by the EPA or the DOE.
 Since they use less energy, these products save
money and help protect the environment by causing
less harmful emissions from power plants.

15. Energy star logo:
 Any building or product that has received an Energy
Star rating carries a blue logo, pictured below.
 Only the most efficient products in a class carry the
ENERGY STAR mark.
 The more stars, the more efficient.

16. Benefits of energy star:
 Saves money
 reduce air pollution
 Environment friendly
 Adds value
 Durability

17. Qualified product:
Home electronics
 Washing machines
 Televisions
Office equipment
 Imaging equipment
 computers
Air conditioners
 Heat pumps
 Efficient water heating
Efficient lighting
 LED lighting
 Fluorescent bulbs

18. Room Air Cleaner :
 Display the ENERGY STAR® symbol
 They must be 40 percent more efficient than
standard models
 Air cleaners with features such as a clock
or remote control must consume less than two
watts while in
standby mode.
Example:
3M Company
CCL Products Limited

19. Televisions:
 Qualified TVs consume 3 watts or less when
switched off, compared to a standard TV,
which consumes almost 6 watts on average.
 Example:
Samsung
Panasonic

20. Light bulbs:
 Qualified light bulbs (CFLs) use 70 to90%
less energy than a standard incandescent
bulb
 Energy Efficiency Regulations, which set
minimum energy performance
 Example
Philips
Toshiba

21. Computers:
 ENERGY STAR qualified computer will use
between 30 percent to 65 percent less energy

22. Office equipment's:
 Office equipment that qualifies automatically
enters a low-power "sleep" mode after a
period of inactivity to save energy

23. Energy rating labels:
 The appliance Energy Rating Label acts as an
efficiency indicator
 The label gives the appliances a star rating
between one and ten stars.
 It gives comparison between different
products for the buyer

24. Features:
 Efficient products use less electricity to achieve the
same level of performance of similar models
 Appliances that are labeled up to 6 stars are
considered ‘efficient’ while those above 6 are defined
as ‘super efficient.’
 It tells how much energy the appliance uses in kilowatt-
hours

25. Measurement:
 Manufacturers are required to submit their products to
an approved testing agency
 Testing is undertaken and the appliance’s energy
consumption and overall performance is determined.
 This testing information is used to calculate the
appliance’s hourly or annual kilowatt-hour (kWh) and its
corresponding star rating.

26. Types of energy labeling:
Energy labels are of two types:
 Energy Rating Label:
It is concerned with the star rating
 The EU(European union) energy label:
It rates products from A, (the most efficient) to G (the least
efficient).

27. Categories of labeling:
The energy labels are separated into four
categories:
 Appliance's details
 Energy class
 Appliance type
 Appliance noise

28. Qualified products:
 Fridge or Freezers
 Dish Washers
 Tumble dryer
 Air condition
 Television

29. Fridge and freezer:
 Every new fridge, freezer and fridge freezer
have an energy label
 Since 1 July 2012, all new models must have
a rating of A+, A++ or A+++.
 If you bought your refrigerator before July
2012 it could have an A rating, and if it was
made before September 1999
It could be rated anything
from A to G, with a much
higher energy use than is
allowed today.

30. Dishwasher:
 All dishwashers are graded A+++ to D
 A+++ being the most efficient and cheapest to run
 But if you bought your dishwasher before 2011, it could be rated
as low as G and add a lot of money to your energy bill.
 EU energy rating is determined by testing the energy consumed
washing a collection of soiled tableware and dishes using the
standard cycle recommended by the manufacturer.
 The cleaning, rinsing and drying performance are also evaluated.
 The energy efficiency of the
dishwasher is expressed in kilowatt hours
per year.

31. Advantages:
 Gives information of products at point of sale
 Increase consumer awareness and demand
for energy efficient appliances
 encourage manufacturers to respond to that
market demand.
 works hand-in-hand with a mechanism called
(MEPS).

32. EnerGuide:
 EnerGuide is energy rating and labeling system that
certifies the energy efficiency of new and existing
products and homes
 EnerGuide rating allows you to easily compare the
energy efficiency of major household appliances
 EnerGuide also provides a standard measure of your
home’s energy performance

33. EnerGuide system:
 An EnerGuide Rating measures a home's energy
efficiency level on a scale of 0 to 100
 A rating of 0 represents a home with major air leakage,
no insulation and extremely high energy consumption
 A rating of 100 represents a house that is airtight,
well insulated, sufficiently ventilated
and requires no purchased energy
on an annual basis.
