2/37

Since the industrial revolution, theworld has witnessed incalculable

technological achievements & also

population growth and hence

corresponding increase in resources

use.


3/37

SUSTAINABILITY'... meeting the needs of people today without

destroying the resources that will be needed ... bypersons in the future; based on long range

planning and the recognition of the finite nature

of natural resources...'

SOME GREEN MATERIALS


13/37

Fly ash based cement

Blend of portland cement and high quality fly

ash.

Corrosion resistant.

Impermeable.

Improved workability

High strength

Long life.


14/37

Aerocon blocks:Made up of cement, fly ash, lime & water.

Light weight.

High thermal insulation.

Frost & water resistant.

Fire resistant.

Saves recurring costs of heating and cooling.


15/37

Green Paints:

Low- or no-VOC (volatile organic compound)

paint .

They release no significant

pollutants.

No odour .

Improve overall indoor air

quality.

Generally cost the same as conventional paint .


16/37

Glazing Glass:

Optimizes energy efficiency.

Enhance light penetration.

Good visual and aesthetic

effects.

Proper selection and placement can reduce the

cost of construction.


17/37


18/37

Cork :

Harvested every 9 years from the same tree.

Elastic, anti-static, sound absorbing, insulating

and anti-allergenic.

Mainly used for

flooring.


19/37

Bamboo:

When treated becomes extremely hard and

durable.

Light weight.

Substitute for steel

reinforcing rods.

Cheap and high availability.


20/37

Benefits of Green Materials:

EnvironmentalBenefits

Enhance and protectecosystems and

biodiversity. Improve air andwater quality.

Reduce solid waste.

Conserve naturalresources.

Economic Benefits

Reduce operatingcosts.

Enhance asset value& profits.

Improve employeeproductivity andsatisfaction

Optimize life-cycleeconomicperformance.

Reduces futureliability.

Increase retail sales.

OccupationalBenefits

Improve air, thermal& acoustic

environments. Enhance occupant

comfort and health.

Reduce healthcarecosts.

Improve employeesatisfaction andmorale

Less absenteeismand turnover.


21/37

Green techniques:


22/37

Natural Air Conditioning:

Maximize natural heating and cooling,

reducing the need for air conditioning to the

summer's hottest months.

Right-sized overhangs placed above south-

facing windows can help minimize heat gain

during the summer.

Maximize use of operable windows.

Incorporate whole-house / attic fans.


23/37

Lighting:

Study the sun diagram and place the windows

properly.

Make use of CFLs and LED bulbs for lighting

purpose.

Make majority use of natural light.


24/37

Water Management

Design for dual plumbing

Rain water harvesting.

Use a water budget approach. Use of sprinklers and Drip

Irrigation.


25/37

Energy Generation:

Installation of photovoltaic cell.

Solar water heaters.

Biogas plant. Small wind mills.


26/37

Use of Light Transmitting

Concrete: It is a mixture of thousands of small size

optical glass fibers and fine concrete .

It can be used for both interior as well asexterior walls. (Litracon)


27/37

Use of Light Weight Steel:

It is a 1-2 mm stainless steel hollow micro

sandwiched filled with air as well as millions of

microscopic steel fibers.

Its weight is about half of the conventional

steel.

Kolhapur Institute of Technologys College of Engineering, Kolhapur.


30/37

Located in Takala area , Kolhapur.

Type of building : Bunglow.

Residential building.


31/37

Materials

Red laterite stone for exterior walls.

Jaisalmaier tiles for flooring.

Recycled wood used forcupbords,almariahs & doors.

Use of Green paints.

Fly ash based aerocon blocks used forcompound walls.


32/37

Natural Lighting

Glass Panels on the roof

allow the natural sunlight

into the house.

No need of artificial

lighting during day time.

90% of the building is daylit.


33/37

Energy Generation

20% of the buildings

energy requirement

is catered to by solarphoto voltaic cells.

Solar water heater

systems are installed

on top of the house.


34/37

Water Efficiency

Rain Water

Harvesting

Drip irrigation usedin gardens.


35/37

Garden

The house is surrounded by many trees such aspalm, mango, coconut, papaya, chiku, etc.

Also there are many flowering plants such asrose, chapha, gladiolas, jaswandi, orchids, jasmin,etc.

Hence the house gets a fresh look and the

people staying in the house feel pleasant.


36/37

Conclusion

Vast Applications.

Dominant in developed countries.

Role of government & civil engineers.

Even if some materials or practices are costlier, itis the price to pay for safety !!!
