What is a green building?

A green building is a structure that is

designed, built, renovated, operated,

or reused in an ecological andresource-efficient manner which

makes it a sustainable building while

reducing the overall impact to theenvironment.

Which one of them do you thinkis a green building?

A building in Kansas A building in Belgium


4/36

Irony:

Man first clears

forests to make

space for buildings

Realizes his error

Tries to make his

buildings look like

forests!!!


5/36

Main drawbacks of green

buildings

Higher ownership costs

Additional costs: although usually

balanced by the energy savings, it is

still extra money coming out of the

pocket


6/36

As a result,the typical reaction is

wariness!


7/36

Aim of our project

To compare green buildings withconventional buildings

To research and suggest ways of cost-optimization in green buildings by

innovation in construction materials

To study the Indian,regional and local

scenario in the field of green

construction


8/36

Why choose green buildings?

Energy Savings: 40% - 50%

Water Savings: 20% - 30%

Increase in productivity: 12% - 15%

Availability of fresh air: 15 cfm/person

Savings from carbon emissions: 35%

Uses natural resources efficiently,

maximizes the use of local materials

and eliminates waste

Now WHY to do this?!

saying this as apolitician or chief

common man. I

need localtechnology which

will help me in

Let us bust some common myths

regarding green buildings!!!


13/36

Myths and Realities

Myth 1: Green bu i ld ings are

cost l ier

REALITY

Paradigm 1 - The incrementalcost is always relative and

depends on the extent of eco-

friendly features already

considered during design.

Operating cost works out to

80-85 % while incremental

cost, which is a onetime cost,-


14/36

Paradigm 2 The incremental cost in

relation to the life cycle cost.

Green buildings last for 50, 60 and

even for 100 years.

o The initial cost of a green building

might be high but typical payback

period is of 5-7 years.


15/36

Myth 2: Green bu i ld ings have to be air-conditioned

REALITY

Green building concepts can be applied for non-air

conditioning buildings. It has been applied on three

such buildings in India viz., IGP office, Gulbarga, theRoyal Engineering College, Hyderabad


16/36

Myth 3: Green bui ld ing s take

more time

REALITY

The CII-Godrej GBC building

designing took about 1.5

years while the construction

was completed in about 9

months.


17/36

Why are green buildings

smarter? Site design: Works with natural

features, protects trees, streams, soilsand parks, has effective drainage andenergy saving shade

Indoor air quality: Excludespollutant sources by using non-pollutingmaterials in construction and lets in freshair by keeping vents away from exhausts

Energy efficiency: Reducesbuildings energy requirements andgenerating energy onsite.


18/36

What else can be done?

Materials: Reduce the amountused and to reuse existing buildings or

deconstruction debris. Select materials

that dont require on-site finishing and

avoid toxic products

Waste: Reducing, reuse and recycleconstruction waste. Set up food waste

composting areas near gardens

Water: Use rainwater to irrigate orflush toilets. Put up trees to intercept

runoff. Install a green roof which would

soak up rainfall, save energy and last

longer than the traditional one.

Distinguishing factors between greenbuildings and conventional buildings

ConventionalBuilding Green Building

0.70% Solar energy

0.40% Wind energy No standards for

6% Wood (renewable

resources) used

30% Local materials

30% Solar energy

45% Wind energy 25-80% Recycled

50% Wood used

50% Local materialsare extracted + 20%manufactured= 70%Local materials

facts?

Green building projects in

Ahmedabad

Government initiatives

The Ahmedabad Municipal Corporation isgoing green, not with envy but with eco-friendly buildings!

AMC is planning to build four greenbuildings and converting the new dentalcollege near Anupam Cinema, LG MedicalCollege in Maninagar, corporation buildingat Danapith and the new west zonecorporation office in Bodakdev into greenbuildings.

BEWAREGREEN buildings are not asenergy-efficient as they aremade out to be, according totwo academics at the CEPT

University in Ahmedabad.Prof Miki Desai and ProfNeelkanth Chhaya said thestandards by which green-buildings are measured (evenin India) are developed in theUS, where energyconsumption is very high.

ere o we

come in?There is still a long way to go interms on innovation especially

in materials from the civilengineering point of view!


33/36

We aim tolook into

materials that

reduce costs

further and

paint the worldgreen!
