Managing Energy Consumption

1
Managing Energy Consumption

• ENERGY SAVING IS GOOD IF IT REDUCES OUR
  OPERATIONAL COST.
• ENERGY SAVING IS BETTER IF IT SAVES US MONEY.

2
Monitor Power Management

• Why Should I Use Power Management?
• At TescoHSC over 25 of energy consumed is by
  PCs and Monitors (Do you know how much is 25 in
  cost? 7 Lacs approx)
• More than half of this energy could be saved by
  taking two simple steps
• IT infra to enable power management functions
  that place monitors in low-power mode during
  periods of inactivity.
• Employees initiative to Turn off PCs and
  monitors after work
• These two simple steps will result in ?????

Energy saved Comparison

• Every monitor will consume 100 watts of energy
  per hour
• We have about 1500 monitors at our campus
  approx
• Monitor Usage / day 10 Hrs
• Monitor Unused / day 14 Hrs x 100watts
  1.4Kwh
• 1.4Kwh x 1500 Nos 2100Kwh/day
• 2100Kwh x One month 63000Kwh
• 63000Kwh 63000Units / Month

Can Light 250 residences for about a month

And the fact is .
5
Are we environment friendly ?
DO YOU KNOW? 1 tonne of CO2 emissions is released
by Consuming 2,325 kWh Electricity And we at
TescoHSC alone emit 28 tons of CO2 by consuming
63000kwh /month (Wasted by keeping the monitor ON
when not in use) 75 big sized trees required to
digest 28 tons of CO2 emissions produced by us

How To tell Employees

• Encourage your colleagues to turn lights off when
  rooms while leaving(even if they plan to come
  back in a few minutes).
• If daylight alone is adequate, ask them to leave
  their lights off.
• Use placards in work areas.
• Use signs in public areas.
• Display your Environmental Policy.
• Small signs calling attention to specific areas
  of savings.

Employee Power Saves Energy

• Employee Common Sense makes all the difference in
  energy savings.
• What employees and management know about energy
  saving, helps them to spot energy waste.
• Rewards and incentives remind employees to save
  energy.
• Energy saving practices often save work-hours.

8
Electricity use accounts for 60 to 70 of
utility costs

• HEATING VENTILATION AND AIR CONDITIONING
• GENERAL OPERATIONS

9
Lighting is about 30 to 40 of organization
Electricity Costs.

• Light energy saving rate of 50 or more is
  possible, when workplace is occupied.
• Energy efficient compact fluorescents use a third
  of the watts, making the electric bill smaller
  for the same lighting.

10
Lighting is about 30 to 40 of organization
Electricity Costs.

• Inefficient bulbs create serious heat that can
  run up air conditioning costs.
• CLEANING fixtures once a year can save as much as
  30 in room lighting.
• Is outdoor lighting being used well and inspected
  regularly?

11
The Easy Lighting Cost Savers

• CHOOSE LOWER LAMP WATTAGE. Todays bulbs are
  brighter but use less wattage.
• TURN OFF UN-NEEDED LIGHTS.
• USE TASK LIGHTING. It puts light where it is
  needed, saving wasted overhead lighting.
• INSTALL TIMERS AND MOTION SENSORS. Controls can
  SAVE 10 or more of lighting costs.

12
Heating, Ventilation, and Air Conditioning (HVAC)

• HVAC systems have coils that need cleaning and/or
  filters that need changing. Dirty coils and
  filters cut efficiency and could create many
  thousands of rupees in extra costs.
• HVAC Fan motors and drive belts need maintenance.
  A worn belt can mean 10 extra motor operating
  costs.
• Use Zone and Automatic Controls.

13
Food Court Kitchen Equipments

• Properly use and maintain equipment.
• Periodically clean refrigeration condenser coils
  can save thousands.
• Is there over refrigeration or freezing?
• Can the kitchen exhaust be better balanced?
• Use energy saving appliances.

14
General Operations in Energy

• Are office machines energy efficient?
• Are hot water heaters maintained?
• Are boiler tubes cleaned every few years?
• Are water body pumps and filters cleaned?

15
Energy Bills can LIE

• Problems with meters could go undetected for
  years.
• Compare electric bills with the same periods in
  previous years to detect costly hidden problems
  or practices.
• Rate Schedules can be adjusted once a year to get
  the best rates, as equipment, practices, and
  circumstances change.
• Rate Schedule fees and penalties can show
  something is wrong with your operation.

16
NOW COMES TO WATER

• Ensure that drips from taps or showers are
  stopped.
• A dripping tap or shower can waste 1,200 litres
  of water a year at one drip per second. If the
  drips are breaking into a stream, that water
  wastage could be as much as 32,000 litres per
  year.
