TIPS
IN
LIGHTING SYSTEM

3. 1) One of the best energy saving device is the light switch.
Turn off lights when not required.
2) Many automatic devices helps in saving energy used in
lighting such as
# Infrared sensors;
# Motion sensors;
# Automatic timers;
# Dimmers;
# Solar cells etc.,

4. 3) As far as possible use task lighting, which focuses light
where its needed. For e.g., for reading light must
focuses on study material instead of brightening the
whole room.
4) Dirty tube lights & bulbs reflects less lights & can absorb
50% of the light. Dust your tube light & lamps
regularly.
5) Fluorescent lights & CFL converts electricity to visible
light up to 5 times more efficient than incandescent
bulbs & thus saves 70% of the electricity.

5. 6) 90% of the energy consumed by the incandescent
bulb which gives more heat rather than more light
compared with others (CFL).
7) Replace incandescent bulb with more efficient
Compact Fluorescent Light (CFL) which used up to
75% less electricity than incandescent bulbs.
8) A 15-watt CFL produces the same amount of light
as a 60W incandescent bulb.

TIPS IN
ROOM
AIR CONDITIONERS

9. 1) Use of ceiling or table fan as first line of defense
during summer days.
As because operating cost of ceiling fan about 30
paise per hour where air conditioners operating
costs around 10 rupee per hour.
2) You can reduce the air condition use up to 40%, by
shading your home’s windows & walls by using
green curtains.
3) One will use 3 to 5% less energy by just changing
the AC temperature setting from 20 to 25 degrees.

10. 4) Using ceiling or room fans allows you to set the
thermostat higher because the air movement will
cool the room.
5) A good air conditioner will cool & dehumidify the
room in about 30 min. so use a timer & leave the unit
off for some time.
6) Keep doors to Air conditioned room closed as often
as possible.
7) Clean the Air conditioner filter every month. A dirty
air filter reduces air flow & may damage the unit.
Clean filters to cool the room quickly & use less energy.
8) Instead of repairing old AC buy new energy efficient AC.

11. ENERGY SAVING
TIPS
IN
REFRIGERATION

12. 1) Make sure that refrigerator is kept away from all
heat sources such as direct sunlight, appliances such
as oven & cooking ranges.
2) When its dark place a little light insight inside the
refrigerator & close the door. If light around the
door is seen then the seal need to replace.
3) Refrigerator motors & compressors generate heat, so
allow enough space for continuous air flow around
refrigerator. If not then refrigerator will work more
to maintain the cooling temperature.

13. 3) A full refrigerator is fine thing, but be sure to allow
adequate air circulation inside.
4) Think before what you need before opening the
refrigerator door. You will reduce the amount of
time the door remains open.
5) Allow hot & warm foods to cool & cover them well
before putting them in refrigerator. Refrigerator will
use less energy & condensation will reduce.
6) Make sure that refrigerator’s rubber door seals are
clean & tight. If any leakage is seen then replace
seals immediately.

14. 7) When dust builds up on refrigerators condenser
coils, the motor works harder & uses more
electricity. Clean the coils regularly to make sure
that
air can circulate freely.
8) For manual defrost refrigerator, defrost freezer
compartment regularly.

15. ENERGY SAVING TIPS
IN
WATER HEATER

16. 1) To reduce heat loss, always insulate hot water pipes
when they run through unheated areas. Never
insulate plastic pipes.
2) By reducing the temperature setting of water heater
from 60 – 50 degrees, one could save over 18% of
the energy used at the higher setting.

17. ENERGY SAVING TIPS
IN
MICROWAVE OVENS

18. 1) Microwaves save energy by reducing cooking
times.
One can save up to 50% on your cooking energy cost
by using microwave instead of regular oven.
2) Microwave cook food from the outside edge towards
the centre of the dish, so if you are cooking more
than one item, place larger & thicker item outside.

19. ENERGY SAVING TIPS
IN
ELECTRIC KETTLES

20. 1) Using an electric kettle to heat the water is more
energy efficient than other electric cooking element.
2) When buying a new electric kettle, choose one that
has an automatic shut off button & heat resistant
handle.
3) Do not overfill the kettle for just one drink. Heat
only the amount of water you need.

21. ENERGY SAVING
TIPS IN
COMPUTERS

22. 1) Turn off your home office equipment when not in
use. A computer that runs 24 hours a day uses more
power than an energy efficient refrigerators.
2) If your computer must be left on, turn off the
monitor; as monitor consumes more than the half of
total energy used in computer system.
3) Setting computer, monitors & copiers to use sleep
mode when not in use which helps cut in energy
costs by approximately 40%.
4) Battery chargers for laptops, cell phones & digital
cameras pull the power when they are connected to
the supply pull the plug & save the energy.

Instruments
Electrical Measuring Instruments:
These are instruments for measuring
major electrical parameters such as kVA,
kW, PF, Hertz, kvar, Amps and Volts. In
addition some of these instruments also
measure harmonics.
These instruments are applied on-line i.e
on running motors without any need to
stop the motor. Instant measurements
can be taken with hand-held meters,
while more advanced ones facilitates
cumulative readings with print outs at
specified intervals.
Combustion analyzer:
This instrument has in-built chemical
cells which measure various gases such
as CO2, CO, NOX, SOX etc
Fuel Efficiency Monitor:
This measures Oxygen and temperature
of the flue gas. Calorific values of
common fuels are fed into the
microprocessor which calculates the
combustion efficiency.
Fyrite:
A hand bellow pump draws the flue gas
sample into the solution inside the fyrite.
A chemical reaction changes the liquid
volume revealing the amount of gas.
Percentage Oxygen or CO2 can be read
from the scale.
Contact thermometer:

28. Contact thermometer:
These are thermocouples which measures
for example flue gas, hot air, hot water
temperatures by insertion of probe into
the stream.
For surface temperature a leaf type probe
is used with the same instrument.
Infrared Pyrometer:
This is a non-contact type measurement
which when directed at a heat source
directly gives the temperature read out.
Can be useful for measuring hot jobs in
furnaces, surface temperatures etc.
Pitot Tube and manometer:
Air velocity in ducts can be measured
using a pitot tube and inclined manometer
for further calculation of flows.
Ultrasonic flow meter:
This a non contact flow measuring device
using Doppler effect principle. There is a
transmitter and receiver which are
positioned on opposite sides of the pipe.
The meter directly gives the flow. Water
and other fluid flows can be easily
measured with this meter.

Instruments
Tachometer Stroboscope
Speed Measurements:
In any audit exercise speed measurements
are critical as thay may change with
frequency, belt slip and loading.
A simple tachometer is a contact type
instrument which can be used where
direct access is possible.
More sophisticated and safer ones are
non contact instruments such as
stroboscopes.
Leak Detectors:
Ultrasonic instruments are available
which can be used to detect leaks of
compressed air and other gases which are
normally not possible with human
abilities.
Lux meters:
Illumination levels are measured with a
lux meter. It consists of a photo cell
which senses the light output, converts to
electrical impulses which are calibrated
as lux.
