Transcript of Energy Management in Buildings

ENERGY MANAGEMENT IN BUILDINGS
Industry 25%
Transport 20%
Agriculture 20%
Buildings 30%
Average 25%
The Energy Pyramid
It takes one hour to promote energy conservation, but only one second to save energy.
Reduce Energy Intensity and
Carbon Emissions
By Changing the Way You Use Energy
Energy Management (EM) is an activity organized to optimize the use of energy by avoiding waste

Energy management is not just about implementing energy efficient technologies
  
its about OUR behaviour
Energy Efficiency is an escalating concern!
Generation Capacities and Grids
Natural Resources are Declining
Demand is Booming
Possible Savings for Pakistan by EC
US $ 2 Billion/Year.

Renewable Energy “is the peak of the pyramid and thus should be the last part of the pyramid to be built.
'Energy Conservation'
refers to the efforts made to reduce energy consumption
'Energy Efficiency'
refers to save energy by adopting more efficient means
Switch off: don’t leave on standby
To turn the heating/ AC notch down
Case Study
20 Tube Lights
8 hours/day
2040 hours/year
T8 Triphospor + Magnetic Ballast
Capital Cost 10,000 PKR

Total Energy Consumed 1,468.8 KWH

ENERGY STAR
Energy Saving Tips

Turn off equipment when not in use
Close curtains, shades and blinds
Regularly clean and perform maintenance on appliances
Lighter coloured walls
Set thermostats -78°F in summer & 68°F in winter
T5 Triphosphor + Electronic Ballast

Analyse your SAVINGS?
Capital Cost
T8 is cheaper than T5
Energy Saved
326.4 KWH saved
Cost of Electricity
5,875 PKR saved
CO2 Offset
300 Kg less CO2 Offset
Activity Answers
No. of bulbs: 10
No. of bulbs: 10
Cost of 1 bulb: Rs. 20
Cost of 1 bulb: Rs. 25
Find the Capital Cost and the ENERGY consumed in 1 day?
Energy Consumed= Power * No. of bulbs* Time
Incandescent Light (IL)
Capital Cost= 20*10
= 200 PKR
Capital Cost=25*10
= 250 PKR
Compact Fluorescent Lamps (CFLs)
Energy= 24*100*10
= 24,000 KWH
Energy= 24*18*10
= 4,320 KWH
