Economic Evaluation and Comparison
between Green Building and
Conventional Building

3. Introduction to Project
• Economy is the major factor in any type of construction work,
especially for residential houses and more specifically when they
are situated in the megacity in a Developing country like India.
• There is a need of concentrating on a Green Home, which is one of
the most important and one of the most discussed topics
throughout the globe, in the age of global warming and climate
change worldwide.
• In this situation, some middle way is necessary to be found out, to
encourage the Green Construction.

4. Introduction to Project
• Aim:
The aim of the project is to “Find out a simple and economical
way of constructing a Green Home which a common man from a
middle class or an upper middle class family can easily afford.”

5. Introduction to Project
• Objective:
The objectives of the project are:
i. To compare the cost of construction of a home as a Green
Home & a Conventional Home.
ii. To find out energy and water savings in a Green Home over
the Conventional home.
iii. To find out percentage increase while constructing a Green
Home instead of a Conventional Home.
iv. To find out the middle way to encourage the Green
Construction.

6. Introduction to Project
• Need of The Project:
The reasons why this project is important are listed below:
i. It is general belief that a Green Home will cost much more
than a Conventional Home, but some middle way is required
to be found out by analyzing the real situations & conditions
in the market.
ii. In these days, when everyone is talking about the Green
construction, there is need of a way by which a common can
afford a Green Home.

7. Introduction to Project
• Scope of The Project:
The Scope of the project is listed below:
i. This typical case selected in the project would be useful while
considering cases for residential sites.
ii. This project will be identical for the persons who are
associated with this type of work, to construct a Green Home
rather constructing a Conventional House, bearing some extra
initial costs which will be paid back in some years after
starting the use.
iii. This will be beneficial for the people who are really conscious
about the environmental impact of the buildings and believe
in energy conservation.

8. Introduction to Project
• Methodology:
The figure below represents the Methodology in Chart format:

9. Introduction to Green building
• Definition:
“A green building is one which uses less water, optimises
energy efficiency, conserves natural resources, generates less waste
and provides healthier spaces for occupants, as compared to a
conventional building.”
• Elements of Green Building:
There are 4 elements of Green Building. That shows the main
points required to be considered while designing any building.
• Smart Design
• Energy Efficiency
• Eco Materials
• Water Conservation

19. Green Materials
IG Units:
• Nearly 15-20% of all home energy
is lost via windows and doors,
having energy efficient windows in
your home should be a priority.
• For that, the best suitable option is
to use Low-E glasses.
• The main aim of DG Glasses is to
prevent heat on the side of glass
where it originates.

20. Green Materials
LED Fixtures:
• In green buildings, the only type of the lighting fixtures used is LED
(Light Emitting Diode) Fixtures.
• This type of lighting fixtures are somewhat costly, approximately 4
times higher prise than the normal ones.
• These are solid lights which are extremely
energy-efficient.
• A significant feature of LEDs is that the
light is directional, as opposed to
conventional bulbs which spread the
light more spherically.
• Different types of LED fixtures are Shown in the table 5.3 of report.

21. Green Materials
Plumbing:
• In the Green Plumbing the Plumbing Fixtures discharge ranges from
5 l.p.m to 15 l.p.m.
• Green Plumbing includes the Fixtures as below:
– Faucets discharge ranges between 5 l.p.m to 8 l.p.m.
– Showers discharge ranges between 10 l.p.m to 15
l.p.m.
– Water Closet (W.C.) discharge ranges between 7 l.p.m
to 12 l.p.m.

22. Green Materials
PVC flooring:
• PVC vinyl flooring is a type of synthetic flooring.
• Floors such as wood and marble are made from natural materials,
but PVC vinyl flooring is made from a synthetic plastic called
polyvinyl chloride.
• It is easy to install.
• PVC vinyl flooring is affordable, water resistant and very durable.
Due to its synthetic nature, PVC vinyl flooring is also more
customizable than natural flooring.
• To keep PVC vinyl flooring in optimal condition, regularly vacuum
and polish the floor. Never use any rough-surfaced cleaning tools on
the floor, as they often result in scratches.

23. Green Materials
Green Wood Or Engineering wood:
• Engineered wood products are made from a combination of wood
fibres, strips, and veneer sheets.
• Smaller diameter trees of the same hard and soft wood used to
manufacture lumber are also used.
• Engineered wood products are also called composite wood, and the
materials are bonded together using an adhesive resin which makes
the finished product resist warping.
• Some different products made from engineered wood include
flooring, several types of lumber, and particle board

24. Green Materials
Green Paints:
• paints with reduced levels of VOCs are more eco-friendly than
conventional paints, some house paints have an even lower
environmental impact.
• Homeowners can select premium-grade zero-VOC paints that also
use VOC-free colorants, are free of vinyl and other plasticizers and
include no toxic biocides.

25. Green Materials
Bricks:
• Flyash Bricks are considered as the Green material of construction.
• So in this case it is used in the Green Construction.
Cement:
• If PPC (Portland Pozzolana Cement) is used in construction, it will be
green Material Because PPC contains the flyash as the main
ingredients.

26. Green Materials
Rain Water Harvesting:
• The principle of collecting and using precipitation from a
catchments surface .
• There are two main techniques of rain water harvestings.
– Storage of rainwater on surface for future use.
– Recharge to ground water.

27. Energy Savings
• The savings in the energy will be 70% per year, which is near about
` 10,000 per year.
• The life of the LED fixtures will be more than 17 years
(50000/8/365=17.12). Same way the life of the tubelight is about 5
years (15000/8/365=5.14) and that of the CFL is about 2 years
(6000/8/365=2.05).

28. Water Savings
• Water fixtures use per day per person (6 persons):
– Basin : 4 Times a day
– Sink : 4 Times a day
– Wash Area : 4 Times a day
– Shower : 2 Times a day
– W.C. : 1 Times a day
– Urinals : 3 Times a day
• Total Water Saved = 74 liter/ day/ person
=74*6=444 liter/day

29. Cost Analysis and Comparison
• The analysis and the comparison of cost for each item is as shown
in the chapter 6 of the report.

30. Cost Comparison

31. Cost Analysis and Comparison
• The Chart bellow shows the Cost Comparison of each Item:

32. Conclusion
1) If the Home is Constructed as a Green Home in this project, the total
cost increases by ` 4,02,130, in addition to the total construction cost of
the Conventional home which is found to be ` 31,07,415.
2) The percentage increase in total construction cost is 12.94% (say, 12 -
15%).
3) The saving in money, which is about `10,000, will be the clear saving
after the payback period of LED fixtures is completed.
4) Water saving is about 444 (say, 440) liter/day.
5) Payback period, considering savings only in the electricity bills, is found
to be 35 years.
6) So, on the bases of the above figures, it can be concluded that:
– “If the intention is to construct a new Home to live in, it is advisable to go for
a GREEN HOME rather than the ordinary conventional home. Because, the
percentage increase of 12.94% in the total cost is not a negligible amount
when the intention is just to renovate or retrofit an Old Home”
