Green Buildings Conventional Buildings
By fixing the flow fixture
(Taps) to less than 12
litre/min and by providing
dual flushing system for
6/3L water closet at a cost
of Rs.35,000/- for a single
flat, water is saved up to
50L/day from each flat
In conventional buildings the
flow fixture(Taps) are fixed
higher than 12 litre/min and
only single flushing systems
are provided for water
closet, at a cost of Rs.20,000/-
for one flat. Thus there is no
saving in water
1. Plumbing

2. Water
For one person 135L/day
of water is required and
from this 54L/day is
required for flushing
For one person 135L/day of
water is required all of which
is pumped from ground water

In green buildings
this requirement is met by
supplying water from
sewage treatment plant
which is sent by a separate
pipe line
During acute water scarcity
there will be problem in
sourcing this quantum of
water, so additional expense is
required for purchase of water
2. Water

So, effectively only 81L/day
is pumped and used from
ground water
No such facilities
2. Water

Similarly, for gardening
water from sewage
treatment plant is used, so
that maintenance cost is
low
For gardening water is used
from ground water so that
maintenance cost will be
higher
2. Water

Treated water from sewage
treatment plant is used for
flushing and gardening, the
remaining water is
percolated to the ground
to increase the ground
water table
There is no special treatment
done separate pipe lines are
not used to reusing the treated
water
2. Water

Since ground water table is
always maintained at
higher land there will never
be a water scarcity even
during peak summer in
places like Chennai
It is very difficult to manage
under acute water scarcity, as
there is no system to recharge
the treated water

3. Electrical
Since the heat
transformation is minimum
through hollow core slabs,
sandwich panels and
concrete panels the loss of
cool air inside the building
is minimum. Thus reducing
electricity consumption to
a great extent to cool the
building
Since the heat transformation
is maximum through
conventional slab and brick
wall or hollow blocks, loss of
cool air inside the building is
more. Thus electricity
consumption is more

3. Electrical
Window glass used are
reflective glasses which
cost Rs.100/- per sq.ft
more than plain glass. This
reduces the heat transfer
into the building
Only plain glass are used
hence heat transfer is high

3. Electrical
The electricity consumed is
only 9 units to run 8 hours
of A/C. Since the building is
very cool, the thermostat
mode will be activated
which can save 2 hours of
running A/C which means 3
units/day and 90
units/month is saved
The electricity consumed is 12
units to run 8 hours of A/C
during night time

3. Electrical
For common area only
CFL/LED bulbs are used
which is expensive but
consumes less electricity
For common area only
ordinary high watt bulbs are
used which consumes more
electricity

4. Paint
Smell from the normal
paint is harmful to human
health, so only low VOC
paints @the rate 210/L is
used
Normal paint is used which is
harmful for human health and
costing only Rs.52/L

5. Landscape
We plant only those plants
which consume less water,
so we can save more water
Generally normal plants are
used which consumes more
amount of water

6. Ventilation
Windows and ventilators
are provided for proper air
circulation and day light
entry into the building
No proper air circulation and
day light entry into the
building

6. Ventilation
This enables to save more
Electricity and provides
good health. This done
using energy simulation
software
No savings in electricity and
leads to human diseases like
asthma, headache,
cardiovascular stress,
respiratory infection etc.

6. Ventilation
Chemicals used in
household furniture and
products in buildings
will not affect the air
quality because air
circulation through
windows is properly
designed
Chemicals used in household

7. General
Provision for charging
batteries for electrical
vehicles is provided in the
car parking area thus
motivating use of battery
run vehicles
Provision for charging batteries
for electrical vehicles in the car
parking area is not provided

7. General
All elements are cast in
factory and brought to site
for erection thus
eliminating all pollution
while construction is done
All elements cast at site, thus
polluting the surrounding
while construction is done

7. General
Government is promoting
green buildings and there
are proposals to give
subsidies in property tax
for green rated buildings
Government is not promoting
conventional buildings and
there are no subsidies in
property tax
