` Reasons for discussing energy efficiency (EE)of fans

` Indias efforts to improve appliance efficiency

` Challenges for the labeling program for fans Fan industry

Consumer awareness and preferences

Results of labeling for fans

` A novel approach - Super-Efficient Equipment

Program (SEEP) for fans with upstreamincentives


3/15

` Fans most common electrical appliance in

South Asian households and offices afterelectric lights Almost never discussed when talking about EE

` Fans consume about 20% of the electricity in

Indian households` Sales of ~30 million per year; growing at ~10%` About 70% of the fans in 2020 will have been

added after 2010. Rapid accumulation of new stock with long life -

should be efficient


4/15

` In 2001 Govt of India passed Energy Conservation Act

` In 2002 Bureau of Energy Efficiency (BEE) formed Primary objective to reduce energy intensity of economy One responsibility - to recommend to Govt standards and

labels (S&L) for appliances

` BEE uses market-based approach to S&L

Voluntary until 50% of market starts using labels Then mandatory, with lowest star level become de-facto

minimum energy performance standard (MEPS)

Threshold levels to be made more stringent every 2-3 years

`

Currently labeling program for 14 appliances, withfour being mandatory Fan labeling program voluntary


5/15

` Segments

Organized sector ~ 70% Small and local manufacturers ~ 30%

` All leading brands outsource verysubstantial numbers from clusters

` All leading brands have standard designs70-80 W

` Customers want fans with high speed

and that throw a lot of air.` Not much awareness about EE fans.


6/15

` Five levels - highest (5-Star) having ServiceValue = 4 cmm/W

` Minimum air flow of 210 cmm

` Voluntary now, may be made mandatory Concern in organized sector of loss of market share

to unorganized sector if mandatory standard.

` Self certification by manufacturers but checkand challenge testing carried out by BEE.


7/15

` In 2011, labeled fans < 2% of the sales

`

Unfortunate association of low air flow withenergy efficiency Even sales staff were discouraging purchase of 5-

Star fans

` A number of 5-Star rated products failingcheck testing Issues about non-repeatability of tests

x Impact of environment on measurement of air flow andpower consumed.


8/15

` New way of delivering energy efficiency

` A leap in energy efficiency of product

Essential Feature: Use of upstream incentives

to bring about a market transformation at thenational level

By expanding geographic scope of program and giving incentives upstream,SEEP will rapidly accelerate the shift to more efficient appliances.

10/15

` Reduced transaction costs Easier to work with handful of manufacturers rather

than change behavior of millions of consumers.` Lower incentive required` Increased bargaining power with

manufacturers` Helps with design and deployment of

appliances better suited to South Asianconditions.

` Can bring about rapid transformation ofmarket.

` Current designs use single phase inductionmotors

` Standard fans consume 70-80W at full speed` EE can be improved by

Increase stack height (increase the iron)

Make wires thicker (more copper) General view - Can bring consumption down to

~45W, but no consensus on this view

` Can lower consumption even further Use brushless DC motors (BLDC)

x PM synchronous motor with inverter synchronized tomotor

Example of Super-Efficient Fan


13/15

` On January 9, 2013, Govt of India issuedinvitation for Expression of Interest for fanmanufacturers to participate in SEEP

` Many parties developing fans to meet SEEPspecs.


14/15

` Ceiling fans big consumers of electricity.Important to focus on improving EE of fans.

` Standard and Labeling Program can be usefulin improving EE of fans. Some concerns: Adequate capacity for check testing

Adequate testing facilities required Media campaign to increase awareness and training

of retailers essential

` Upstream incentive program promoting

super-efficient can bring about rapidtransformation of EE of fans.
