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

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

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.

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.

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

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

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

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

Disadvantages of MEPS: Requires consensus/cooperation among

multiple stakeholders Can incur some up-front costs to

consumers Requires good enforcement policy

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

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

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.

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.

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

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

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 CompanyCCL Products Limited

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

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

Computers: ENERGY STAR qualified computer will

use between 30 percent to 65 percent less energy

Office equipment's: Office equipment that qualifies

automatically enters a low-power "sleep" mode after a period of inactivity to save energy

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

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

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.

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).

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

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

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.

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.

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).

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

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.

Products :The products that are tested by energuide testing method to be rated are: clothes dryers clothes washers dishwashers electric ranges, cook tops and ovens freezers refrigerators

Energy Rating Calculator: To find out the energy efficiency of a product,

energy rating calculator is the easiest way of doing that.

Step1: Select an appliance. Step2: Select your usage details Step3:Adjust the energy rating slider. By

adjusting this , the max energy consumption, the running cost per year and the green house gas emission will automatically valued down.
