2. INTRODUCTION
The concept of Green Building came into practice to
meet the demand of society without hampering the
environment. The building with zero net energy
consumption, meaning the total amount of energy used by
the building on an annual basis is roughly equal to the
amount of renewable energy created on the site.
These buildings sometime depend on conventional
grid power because of cloudy days and on short winter
days. Buildings that produce a surplus energy over the year
may be called “Energy Plus Buildings” and buildings that
consume slightly more energy than they produce are called
“ultra-low energy houses”.

3. Definition of Green Building
• Sustainable design can be defined as, “A design philosophy that seeks to
maximize the quality of the built environment, while minimizing or
eliminating negative impacts to the natural environment”
• Green Buildings can be defined as, “Buildings that are designed,
constructed and operated to boost environmental, economic, health and
productivity performance over conventional building”
There are several benefits of concept of sustainability in
construction industry:
 Minimizing operating and maintenance cost.
 Minimizing construction wastes
 Increasing occupant health and satisfaction.
 Integration of renewable energy resources
 Integration of plug-in electric vehicles

 Right Site
 Minimum Energy Use
 Material Selection
 Indoor Air Quality
 Efficient Water Usage
 Waste Management
 Amenities and Management
 Economic Benefits of Green Building

Some benefits, such as improving occupant health, comfort, productivity,
reducing pollution and landfill waste are not easily quantified. For this reason, consider
setting aside a small portion of the building budget to cover differential costs associated
with less tangible green building benefits or to cover the cost of researching and
analyzing green building options
Scope of Work
A green building has lot of advantages, but due to unawareness of people green
buildings has been seen as very expensive for construction and operation.
In real sense, a conventional building has many harmful impacts on human being,
global environment.
This work will contribute to sustainable development by finding out the important
parameters in green building construction. The relative importance based questionnaire
prepared according to Satty scale.
Questionnaire survey has been carried out through green building consultants and civil
engineers. Based on their responses analysis of data will be carryout with the relative
importance of green building parameters. Green building practitioners will get a fast-
track to move on sustainable path.

OBJECTIVE OF WORK
The following are the objectives of the study.
1) To study different international and Indian literature to find out
Green Building Assessment Tools by using literature papers,
Journals, books etc…
2) To find the factors of decision making units with the help of
literature review.
3) To carryout questionnaire survey from technical experts & Collect
the data regarding Parameters.
4) To suggest green efficiency increasing factors for implementation
in residentialbuildings

METHODOLOGY
This study based on need of current scenario for eco-
friendly construction. Based on literature review green
building parameters are identified.
The weights of parameters have been calculated by Multi-
criteria decision making methods. With the help of arithmetic
average method ranking of green building parameters has
been carried out.
According to outcome of analysis, suggestions have been
proposed for eco-friendlyconstruction.

LITERATURE REVIEWS
As per Eco- housing assessment criteria, 2009, They provide the
Eco-housing rating system in which Version I was developed by
International Institute for Energy Conservation (IIEC), while
Version II is applicable to all residential buildings, building
complexes and single family residences in all climatic zones in
India. Design principles of Version II are ease of use, applicability
across all the climatic zones in India and parity I application across
the climatic zones. Version II comprise of 77 measures spread over
seven focus areas. Following table shows the Eco-Housing green
building rating system criteria,

As per Chandratilake and Dias (2013), in this paper Questionnaire survey was
carried out among key professionals in the Sri Lankan construction industry with 17
respondents each from architects, civil engineers and quantity surveyors making a
total of 51 respondents. Direct ranking and AHP method used for weighting.
Comparison of domain weights of environment assessment methods in other
national contexts was carried out. Conclusion of research is Site selection received
top rank, Energy efficiency on second rank, water efficiency and materials received
roughly equal weight in Sri Lankan context.
As per Ramesh and Khan (2013), discussed the role of energy efficiency in green
building in Indian Scenario to reduce the energy consumption and environmental
degradation through Green House Gas emission (GHG). Buildings are the dominant
energy consumers in modern cities account up to 40 degree energy consumption.
Author concludes that, maximum consumption of these energy materials is a reason
for environmental degradation. LEED rating provided opportunities to introduce
new products and materials.

As per Kuzman et.al (2013), states that AHP analysis can help professionals and
future dwellers to make a reasonable choice on further optimizing and developing a
particular aspect of the building process by giving them the possibility of comparing
different alternatives on a common and comprehensive basis. As per Bhatt and
Macwan(2012), made an attempt to develop sustainability global weight of various
parameters for the assessment of Sustainable Buildings.For analysis purpose SB
Tool:2007 rating system is taken as base. Questionnaire survey was conducted and 37
responses of consultants from different region of India were collected. Authors
suggested five most important parameters for Indian future sustainable development,
given below:
 Use of renewable energy for building operations.
 Optimum energy performance from non-renewable energy sources.
 Water use reduction.
 Reduced waste water generation on site.
 Energy use accountability

RESEARCH METHODOLOGY
Based on literature review and discussion with green
building expert 42 factors were identified. Also, based on literature
review related to MCDM Analytic Hierarchy Process (AHP),
Arithmetic Average Method (AAM), and Entropy methods of
analysis selected.
Based on literature review and discussion with green
building expert 42 factors were identified. Also, based on literature
review related to MCDM Analytic Hierarchy Process (AHP),
Arithmetic Average Method (AAM), and Entropy methods of
analysis selected.
Firstly, identified green building factors are studied properly
and they are grouped into 7 main criteria. For finding weights of
these 7 main criteria AHP method has been used. The resulted
weights from AHP analysis has been considered as one of the input
for Arithmetic Average Method analysis. In Arithmetic Average
Method and Entropy analysis 42 sub-criteria considered for further
analysis. So, finally AHP analysis considers 7 main criteria, and
