Green building, also known as sustainable construction, aims to reduce environmental impact through resource efficient design and construction practices. It includes techniques like optimizing energy efficiency, using renewable materials, and generating less waste. The key goals of green building are to efficiently use energy, water and other resources; improve occupant health; and reduce pollution and degradation. Some benefits include reduced operating costs, improved productivity, and protection of natural environments and human health. While green buildings have advantages, there can also be challenges like higher initial costs, longer construction timelines, and ensuring proper indoor air quality.

2. WHAT IS GREEN BUILDING?
• Green building (also known as green
construction or sustainable building) expands
and complements the building design concerns
of economy, utility, durability, and comfort.
• A Green Building is one which uses less water,
optimizes energy efficiency, conserves natural
resources, generates less waste and provides
healthier space for occupants as compared to
conventional buildings.

3. GREEN BUILDING CONCEPT
 The ‘GREEN BUILDING’ concept is gaining
importance in various countries, including
India. These are buildings that ensure waste is
minimized at every stage during the
construction and operation of the building,
resulting in low costs, according to experts in
technology.
 A Green building is a structure that is
environmentally responsible and resource
efficient throughout it’s life cycle.

4. OBJECTIVE
-Green building are designed to reduce the overall
impact of the built environment on human health
and the natural environment by:
 Efficiently using energy, water and other
resources.
 Protecting occupant health and improving
employee productivity.
 Reducing waste, pollution and environment
degradation.

5. GOALS OF GREEN BUILDING
 Green building brings together a vast array of
practices and techniques to reduce and ultimately
eliminate the impacts of buildings on the environment
and human health. It often emphasizes taking
advantage of renewable resources, e.g., using sunlight
through passive solar, active solar, and photovoltaic
techniques and using plants and trees through green
roofs, rain gardens, and for reduction of rainwater
run-off. Many other techniques, such as using packed
gravel or permeable concrete instead of conventional
concrete or asphalt to enhance replenishment of
ground water, are used as well.

6. FUNDAMENTAL PRINCIPLES
OF GREEN BUILDING
,

7. STRUCTURE EFFICIENCY:
It is the concept of sustainable building and has
largest impact on cost and performance.
It aims to minimize the environment impact
associated with all life-cycles.
ENERGY EFFICIENCY:
The layout of the construction can be strategized
so that natural light pours for additional warmth.
Shading the roof with trees offers an eco-friendly
alternative to air conditioning.

8.  To reduce operating energy use, high-efficiency windows and
insulation in walls, ceilings, and floors increase the efficiency
of the building envelope, (the barrier between conditioned
and unconditioned space). Another strategy, passive solar
building design, is often implemented in low-energy homes.
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.
 Onsite generation of renewable energy through solar
power, wind power, hydro power, or biomass can
significantly reduce the environmental impact of the building.
Power generation is generally the most expensive feature to
add to a building

9. WATER EFFICIENCY:
To minimize water consumption one should aim
to use the water which has been collected, used,
purified and reused.

10. MATERIAL EFFICIENCY:
-Green building materials are composed of renewable, rather
than nonrenewable resources. Green materials are
environmentally responsible because impacts are considered
over the life of the product. Depending upon project-specific
goals, an assessment of green materials may involve an
evaluation of one or more of the criteria listed below.
Green building material/product selection criteria :
 Resource efficiency
 Indoor air quality
 Energy efficiency
 Water conservation
 Affordability

11. RESOURCE EFFICIENCY
 Recycled Content: Products with identifiable recycled
content, including postindustrial content with a
preference for post consumer content.
 Resource efficient manufacturing process: Products
manufactured with resource-efficient processes including
reducing energy consumption, minimizing waste (recycled,
recyclable and or source reduced product packaging), and
reducing greenhouse gases.
 Locally available: Building materials, components, and
systems found locally or regionally saving energy and
resources in transportation to the project site.
 Durable: Materials that are longer lasting or are
comparable to conventional products with long life
expectancies.

12. WASTE REDUCTION:
It is probable to reuse resources.
What may be waste to us may have another benefit to
something else
 To reduce the impact on wells or water treatment plants,
several options exist. "Greywater", wastewater from
sources such as dishwashing or washing machines, can be
used for subsurface irrigation, or if treated, for non-
potable purposes, e.g., to flush toilets and wash cars.
Rainwater collectors are used for similar purposes.
 Centralized wastewater treatment systems can be costly
and use a lot of energy. An alternative to this process is
converting waste and wastewater into fertilizer, which
avoids these costs and shows other benefits.

13. INDOOR ENVIRONMENTAL QUALITY ENHANCEMENT
 Indoor Air Quality seeks to reduce volatile organic compounds, or
VOCs, and other air impurities such as microbial contaminants.
Buildings rely on a properly designed ventilation system
(passively/naturally- or mechanically-powered) to provide
adequate ventilation of cleaner air from outdoors or recirculated,
filtered air as well as isolated operations (kitchens, dry cleaners,
etc.) from other occupancies.
 Low or non-toxic: Materials that emit few or no carcinogens,
reproductive toxicants, or irritants as demonstrated by the
manufacturer through appropriate testing.
 Moisture resistant: Products and systems that resist moisture or
inhibit the growth of biological contaminants in buildings.
 Systems or equipment: Products that promote healthy IAQ by
identifying indoor air pollutants or enhancing the air quality.

23. BENEFITS OF GREEN BUILDING
• Buildings have a large effect on the
environment , human health and the
economy.
• The successful adoption of GREEN
BUILDING development can maximize
both the economic and environmental
performance of the buildings.

24. SOCIAl

25. ENVIRONMENTAL BENEFITS
• Protect biodiversity and ecosystems
• Improve air and water quality
• Reduce waste streams
• Conserve natural resources

26. SOCIAL BENEFITS
• Enhance occupant comfort and
health.
• Heighten aesthetic qualities.
• Minimize strain on local
infrastructure.
• Improve overall quality of life.

27. ECONOMIC BENEFITS
• Reduce operating costs
• Create, expand, and shape markets
for green product and services
• Improve occupant productivity

28. DISADVANTAGE
 Air-cooling features
• Particular cooling components that control precisely the indoor temperature in
green buildings don’t exist. The only thing that influences it is natural ventilation,
which cannot be regulated.
 Location
• To amend sun exposure, green building may need a correct structural orientation. It
influences how natural light enters the building, how to shade some part of it. As far as
the building will contain recycled resources the location of the building is affected by
the land’s humidity, the circumstance of the surrounding area.
 Availability of materials
• In urban areas materials can be found easily than in rural areas. Green buildings
require special materials. A lot of eco-friendly materials re not available in the US, so
sometimes these materials are hard to find and transportation fees may be high. If you
order them from the internet you should pay additional cost for shipping and handling.
 Time
• To build a green building in some cases takes more time than an ordinary one.
Sometimes it takes too much time to find the needed material. The client can delay
the construction

29.  Green roofs
• Green roofs consist of several layers plus a vegetation layer,
culture medium, drainage, isolation, waterproofing membrane,
and roof support. Green roofs are heavier than simple once, so the
roof’s strength should be improved in order to construct this type
of roof correctly.
 Cost
• Many believe that the cost of green building is cost-prohibitive.
You need to invest a lot of money. However later with energy
saving possibilities the invested money may come back.
 Low indoor quality
• Green buildings are eco-friendly and healthy, but too much
emphases are put on sealing them. This isolation may cause
indoor pollution. It can be harmful to the health of the occupants.
Damage to health can also cause fluorescent lights.
