Sustainable building, or green building, aims to create structures that are environmentally responsible and resource-efficient throughout their life cycle, balancing home building with sustainable environmental goals. Key objectives include minimizing environmental impact, energy and water efficiency, protecting occupant health, and reducing waste. Sustainable materials are crucial, often derived from renewable sources or recycled waste, and while sustainable buildings offer various benefits such as energy efficiency and improved indoor air quality, they may face challenges like higher initial costs and the need for skilled labor.

1. SUSTAINABLE BUILDING
MATERIALS

2. WHAT IS SUSTAINABLE BUILDING ?
 SUSTAINABILITY is defined as meeting the needs of present
generations without compromising the ability of future
generations to meet their needs.

3. Sustainable building or Green building refers to the
structure which are both :
• environmentally responsible and
• resource-efficient throughout a building’s life cycle.
Sustainable building design involves balance between
• Home building and
• Sustainable environment

4. OBJECTIVES OF GREEN BUILDING:
 Common objectives of green building is to :
 Low impact :minimize impact on natural environment
 Energy efficient: reduced energy usage and water usage
 Healthy: protect occupant’s health and increase productivity
 Minimize waste: designed and constructed in a manner that minimizes
waste, pollution and environmental degradation.

5. GOALS OF SUSTAINABLE BUILDINGS
 There are a number of motives for building green, including environmental,
economic, and social benefits.
 It often emphasizes taking advantage of Renewable resources:
for example:
• Using sunlight as passive solar , active solar and photovoltaic equipments.
• Using plants and tress through green roofs, rain gardens etc.
• Reduction of rain-water run-off.

6. PRINCIPLES OF SUSTAINABLE BUILDING:
 STRUCTURAL EFFECIENCY: to minimize the environment
impact associated with all life-cycles.
 ENERGY EFFECIENCY :to reduce the operating energy use.
 WATER EFFECIENCY: reducing water consumption and
protecting water quality.
 MATERIAL EFFECIENCY: materials should be
renewable,recycleable and environment-friendly.

7. WHAT IS A SUSTAINABLE MATERIAL ?
 A sustainable material is any material
that can be put to effective use in the
present without compromising its
availability for use by latter
generations.
 These are mainly renewable materials or
the materials which can be recycled and
reused.

8. SOURCES OF SUSTAINABLE MATERIALS:
TWO MAIN SOURCES
RENEWABLE
SOURCES
REUSE FROM WASTE

9. TYPES OF SUSTAINABLE MATERIALS:
MATERIALS FROM RENEWABLE
SOURCES
 Materials significantly of plant
origin.
 Can be obtained from renewable
sources like solar energy, wind
energy, bio-gas etc.
 E.g.: wood, natural fibers, polymers
etc.
REUSE FROM WASTE
PRODUCTS AS RAW
MATERIALS
 They are typically the products of
recycled matter.
 Materials that can be dismantled and
reused again.
 E.g.: old plumbings, doors, crushed
glass, wood chips etc.

10. WOOL BRICKS
 Obtained by adding wool and
natural polymer found in
seaweed , to the clay of the
brick.
 37 % more strength than the
burnt bricks
 Resistant of cold and wet
climate
 They are dry hard and don’t
need to be fired like other
bricks.

11. SUSTAINABLE CONCRETE
 Concrete is a friend of
environment on all of its life
stages: From raw material
production to demolition.
 Crushed glass, wooden chips or
slag can be added to make it
sustainable concrete.
 reduces CO2 emission of the
building.

12. SOLAR TILES
 They spend a large portion of the day absorbing energy from the sun.
 Not fixed on the top of the existing roofing like other solar units.

13.  Instead they are fully integrated into the building.
 Protects from weather
 As well as generates energy for the inhabitants.

14. PAPER INSULATION
 Made from recycled newspapers and cardboard
 Superior alternative to chemical foams

15.  Insect resistant and fire-retardant because of borax, boric acid and
calcium carbonate( all natural materials )
 Can be blown into cavity walls thus filling every cracks and creating an
almost draft-free space.

16. TRIPLE GLAZED WINDOWS
 Three layered glass windows
 Fully insulated window
frames-Do a better job of
stopping heat from
leaving the building

17. Krypton-is used as an insulator between the layers
Low emissivity coatings to glass-prevents heat from escaping

18. MERITS AND DEMERITS OF
SUSTAINABLE BUILDINGS
MERITS
 Efficient technologies
 Easier maintenance
 Improved indoor air quality
 Energy and water efficient
 Improved health
 Water conservation
DEMERITS
 Initial cost is high
 Availability of materials
 Need more time for
construction
 Need more skilled labors
