4. INTRODUCTION
• Green Buildings(or sustainable buildings) expands and complements the building
design concerns of economy, utility, durability and comfort.
• A green building is one which uses less water , optimises energy efficiency, conserves
natural resources, generates less waste and provides healthier space for occupants as
compared to conventional buildings.

5. OBJECTIVE
The project aims at the following,
• To select and study the energy consumption of an existing residential building.
• Assessment of the selected building using green building assessing tools.
• To adopt techniques to convert the selected building into green building.
• To prepare a 3D model structure showing the green concept to be adopted
• To compare the conventional and green residential building in terms of passive design, material, energy,
water use and energy simulation.
• To conserve the natural resources, reducing the soil waste or zero discharge of waste, improved air and
water quality, protection of ecosystem and biodiversity thus mitigating the adverse impact of the built
environment on human health
• By employing waste management strategies these buildings aim to minimize the burden on municipal
waste management facilities.
• Limiting all kinds of pollution during and after construction is also aimed at to ensure reduced impact on
surrounding environment. These buildings ensure proper safety health and sanitation facilities for
occupants.
• Purpose of project is to convert the selected residential building into green which uses less water,
optimizes energy efficiency, conserves natural resources, generates less waste, and provides healthier
spaces for occupants.

6. METHODOLOGY
The following methodology has been adopted in the present study:
• Site selection and investigation.
• The overall annual water consumptions of building has been obtained.
• The catchment area of the building has been measured
• The amount of water that can be recharged/ regained with the help of rain water harvesting
has been calculated.
• The overall cost for installation of rainwater harvesting system has been computed
• The requirements/feasibility of additional ventilation is determined.
• The overall construction (installation) cost of additional ventilations is calculated
• The amount of energy saved has been reported (approx.
• The amount of money saved per annum has been determined.
• Rating of the building using LEED Certification.
• Comparison of conventional and green residential building and model preparation
• Conducting an audit on thermal variation, waste production and energy and water

7. FUNDAMENTAL PRINCIPLES
• STRUCTURE EFFICIENCY
• MATERIAL EFFICIENCY
• ENERGY EFFICIENCY
• WATER EFFICIENCY
• WASTE REDUCTION
• COST AND PAYOFF

8. STRUCTURE EFFICIENCY
 It is a concept of sustainable buildings and has largest impact on cost and performance.
 It aims to minimize the impact associated with all life cycles
ENERGY EFFICIENCY
 Green buildings often include measures to reduce energy consumption – both the embodied energy required to
extract, process, transport and install building materials and operating energy to provide services such as heating
and power for equipment.
 Designers orient windows and walls and place awnings, porches, and trees to shade windows and roofs during
the summer while maximizing solar gain in the winter. In addition, effective window placement (day lighting) can
provide more natural light and lessen the need for electric lighting during the day. Solar water heating further
reduces energy costs.
WATER EFFICIENCY
 Reducing water consumption and protecting water quality are key objectives in sustainable building.
 One critical issue of water consumption is that in many areas, the demands on the supplying aquifer exceed its
ability to replenish itself. To the maximum extent feasible, facilities should increase their dependence on water
that is collected, used, purified, and reused on-site.

9. MATERIAL EFFICIENCY
 Building materials typically considered to be 'green' include lumber from forests that have been certified
to a third-party forest standard, rapidly renewable plant materials like bamboo and straw, recycled
stone, recycled metal, and other products that are nontoxic, reusable, renewable, and/or recyclable
WASTE REDUCTION
 Green architecture also seeks to reduce waste of energy, water and materials used during construction.
Well-designed buildings also help reduce the amount of waste generated by the occupants as well, by
providing on-site solutions such as compost bins to reduce matter going to landfills.
COST AND PAYOFF
 The most criticized issue about constructing environmentally friendly buildings is the price. Photo-
voltaic, new appliances, and modern technologies tend to cost more money.

10. THREE PRIMARY RATING SYSTEMS
FOR GREEN BUILDINGS IN INDIA
• There are three primary Rating systems in India are as follows
• 1. GRIHA
• 2. IGBC
• 3. BEE

11. GREEN RATING FOR INTEGRATED
HABITAT ASSESSMENT (GRIHA)
• Green Rating for Integrated Habitat Assessment (GRIHA) is India’s own rating system
jointly developed by TERI and the Ministry of New and Renewable Energy, Government
of India. It is a green building design evaluation system where buildings are rated in a
three-tier process.
• The process initiates with the online submission of documents as per the prescribed
criteria followed by on site visit and evaluation of the building by a team of
professionals and experts from GRIHA Secretariat. GRIHA rating system consists of 34
criteria categorized in four different sections.
• Some of them are:
• Site selection and site planning, Conservation and efficient utilization of resources,
Building operation and maintenance, and Innovation.

12. INDIAN GREEN BUILDING COUNCIL
(IGBC)
• The Leadership in Energy & Environmental Design (LEED) is the rating system
developed for certifying Green Buildings. LEED is developed by the U.S. Green Building
Council (USGBC), the organization promoting sustainability through Green Buildings.
LEED is a framework for assessing building performance against set criteria and
standard points of references. The benchmarks for the LEED Green Building Rating
System were developed in year 2000 and are currently available for new and existing
constructions. Confederation of Indian Industry (CII) formed the Indian Green Building
Council (IGBC) in year 2001.
• Indian Green Building Council (IGBC) has licensed the LEED Green Building Standard
from the USGBC. IGBC facilitates Indian green structures to become one of the green
buildings.

13. BUREAU OF ENERGY EFFICIENCY (BEE)
• BEE developed its own rating system for the buildings based on a 1 to 5-star scale.
More stars mean more energy efficiency. BEE has developed the Energy Performance
Index (EPI).

• Total amount of rainfall = 319200 * 0.8 * 0.7 = 178.752 m³ = 178752 litres
• Water requirement = 7350+20% of 7350 = 8820 litres
• For site 2
• Average rainfall in the area = 906.2 mm
• Area of catchment or roof top = 19*9=171 sq meter

27. CONCLUSIONS
• Coped with production of bio waste which can be converted to bio gas, thus reducing
the burning of other fossil fuels. Effective treatment of grey water that can be used for
gardening, flushing etc. Harvesting rain water in order to reduce deal with water
scarcity in dry period. Effective cooling system that provides air conditioning similar to
that provided by an electric air conditioner. Passive design which increases internal air
flow and provides sufficient ambient light. Solar panels help to produce necessary
amount of electricity for household purposes.
• From the analysis of five different buildings we conclude that however the conversion
of traditional building to green building may incur extra cost but it will increase the
LEED rating. And thus, help in development of a healthy environment.
