HOW TO REDUCE CARBON FOOTPRINT

IN MY COLLEGE

Let me first start with the top view of my college, I had also mentioned the places

where a chance of carbon or other green house gas emissions are possibly found.

The rate of emission at different regions is represented by different colours. The place

where highest amount emission takes place is represented by red colour, and the place where high

rate of emission takes place are, the IC lab and air conditioning lab. This is because in an IC engine

lab, during its working high amount of co2 is emitted with the exhaust. Also from the air

conditioning lab gases like hydro chlorofluorocarbons (HCFCs), chlorofluorocarbons (CFCs) and

per fluorocarbons (PFCs) which may be leaked through the old air conditioning and refrigeration

systems.

Other major emissions occur are from generator room, where through the exhaust. In

canteen the emission takes place by burning of wood or kerosene, in air conditioned rooms there is

a chance of emission by leakage, and in store the emission may be caused by printed papers that

contain carbon. and in most of the rooms the emission may be caused by ordinary bulbs, which

produce co2.

ce by the following ways

Thee issions from an air condition lab can be reduced by

re lacing older air conditioning and refrigeration system by a

new one

Theemissions from the bulbscan beeliminated by re lacing

bulbs by CFLs

Old air conditioning system in air conditioning lab can be

re laced by new versions that does not have leaks and having

refrigerants that do not causeemissions

Theemission caused by printer can beeliminated by taking

copies on both sides of a single paper

For energyefficient usage of air conditioning system I have asuggestion that I will e plain below.

Here the waste heat from the refrigeration system is utilized for

heating water which can be used for cooking purpose in

kitchen, thus reducing the amount of heating required for

producing hot water for cooking purpose. Thus reducing the

co2 emission which may be produced during heating of water

by other means. The working of the system can be explained

below.

The schematic of the air conditioning and heat

exchanger is shown below

Here the condenser is replaced by a heat exchanger unit.

Where the heat from the refrigerant is used to heat the water.

And the maximum temperature of the water that can be

produced by using this system is 70 degree Celsius. A specially

designed heat exchanger is used where mixing of refrigerant

with the water is completely eliminated. now the hot water can

be stored in an insulated tank or can be conveyed to the

destination like canteen.

Another method of reducing carbon footprint is by designing

buildings according to the concept of green building. The

designing of green building can be done as follows.

Energy efficiency

Green buildings often include measures to reduce energy use. To

increase the efficiency of the building envelope, (the barrier between

conditioned and unconditioned space), they may use high -

efficiency windows and insulation in walls, ceilings, and floors. Another

strategy, passive solar building design, is often implemented in low-

energy home.

Designers orient windows and walls and place awnings, porches, and

trees to shade windows and roofs during the summer while maximizing

solar gain in the winter.

Water efficiency

Reducing water consumption and protecting water quality are key

objectives in sustainable building.

One critical issue of water consumption is that in many areas, the

demands on the supplying aquifer exceed its ability to replenish itself. To

the maximum extent feasible, facilities should increase their dependenceon water that is collected, used, purified, and reused on -site.

Materials efficiency

Building materials typically considered to be 'green' include rapidly

renewable plant materials like bamboo (because bamboo grows quickly)

and straw, lumber from forests certified to be sustainablymanaged, ecology blocks, dimension stone, recycled stone, recycled

metal, and other products that are non-toxic, reusable, renewable, and/or

recyclable.
