GREEN BUILDING - A SEMINAR REPORT
1.
INTRODUCTOIN
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.
Green building is the practice
of creating structures and processes that are environment friendly and resource-efficient
throughout the life span of a building right from site selection to design,
construction, operation, maintenance, renovation and deconstruction. Green
Buildings are designed to reduce the overall impact on human health and the
natural environment by the following ways:
•
Using energy, water and other
resources efficiently.
•
By reducing waste, pollution,
and environmental degradation.
2.
OBJECTIVES OF GREEN BUILDING
•
The aim of green building design is to minimize resources, maximize the
reuse, recycling and utilization of renewable resources.
•
It maximizes the reuse, recycling, and utilization of renewable
resources.
•
It maximizes the use of efficient building material and
construction practices, optimizes the use of onsite resources and use of renewable
sources of energy, use efficient waste management practices and provide comfortable
and hygienic indoor working conditions.
•
Low Impact
•
Minimize impact on natural environment
•

environmental degradation
3. GREEN
BUILDING FEATURES
•
Structure design efficiency
•
Energy efficiency
•
Water efficiency
•
Materials efficiency
•
Waste and toxic reduction
Structural
Efficiency
•
Its main intensions is to minimize the total
environment impact associated with all life- cycles.
•
It has the largest impact on cost and performance of building.
Energy Efficiency
•
The strategy is to reduce the operating energy
use.
•
Renewable energy through solar power, wind
power, hydro
power and biomass can significantly reduce the environmental impact of a
building.
Water Efficiency
•
Reducing water consumption and protecting water
quality is the key objectives of sustainable building.
•
The use of non-sewage and greywater for on- site use such as site-irrigation will minimize demands on the local
aquifer.
Materials Efficiency
•
Buildings materials should be renewable
materials , recycle and friendly to the environment.
•
Examples are lumber from forest, renewable
plant materials like bamboo and straw and other products that are non-toxic,
reusable, etc.
4. Green Building Rating Systems
•
The objective of green building
rating systems is to evaluate the performance of green buildings.
•
The performance of the building
is evaluated based on following parameters
•
Site planning
•
Building envelope design
•
Building system design (HVAC)
•
Integration of renewable energy
sources to generate energy on site
•
Planning designing,
construction and operation.
Green Building Rating Systems
Used Around The World
5. Different Levels Of Green
Building Certification
•
IGBC Green Buildings addresses
green features under following categories:
•
Site selection and planning
•
Water efficiency
•
Energy efficiency
•
Indoor environmental quality
•
Innovation & design process
6. FUNDAMENAL PRINCIPLES OF GREEN BUILDING
- Sustainable
Site Design
- Indoor
Environmental Quality
- Energy
and Evironment
- Material
and Resources
- Water
Quality and Conservation
Site Selection
and Planning:
- Evaluate each site in terms of the location and orientation of buildings in order to optimize the use of passive solar energy, natural day breezes and ventilation.
- Help to reduce the urban heat island effect by maximizing the use of pervious surfaces, and using light colored roofs, paving and roof gardens.
- Site selection is environmentally responsible
- Building orientation is optimized
- Site disturbance is minimized
7. Energy Efficiency
Energy and Environment
- Use high
performance low-e glazing, which can result in significant year round
energy savings.
- Low-emissivity
glass – also known as low-E glass, uses a microscopically thin and virtually
invisible metal or metallic oxide layer incorporated in the glazing surface
to control heat transfer reducing energy loss by 30% to 50%.
8. Innovation & Design
Process
Materials and Resources:
- Minimize the use of non-renewable construction
material.
- Maximize the use of recycled materials, modern
efficient engineered materials.
- Sustainable managed, bio-based materials.
9. Energy
Efficiency In Indian Building
•
The benefits of energy efficiency in building
are compelling, cost effective and can help consumers to save money in the long
term. It
helps to meet energy targets and resource energy shortage.
•
There is an urgent need to improve the energy efficiency of the Indian
economy. About 70% of the infrastructure in 2030, such as buildings, will be
added in next two decades
•
The projections for energy demand in 2032 imply
a fourfold increase in requirements.
Green Building In India
•
Suzlon Energy Limited (SEL),Pune
•
Suzlon Energy Limited (SEL), India’s largest wind turbine manufacturer,
received LEED Platinum award for their new corporate headquarters in
Pune, Maharashtra, India.
•
Biodiversity Conservation India Ltd (BCIL) -
Bangalore
BCIL's TZed homes in Whitefield, Bangalore has been certified as the
first residential apartment in the world to be rated ‘Platinum’ under LEED.
•
Olympia Technology Park - Chennai
•
The world’s largest LEED ‘Gold’ rated green building.. Built on an area
of 1.8 million sq. ft., this futuristic masterpiece features three mighty
towers on 8.4 acre greenery
10. Benefits of Green
Buildings
•
A Green Building can have tremendous benefits,
both tangible and intangible. The immediate and most tangible benefit is
in the reduction in water and operating energy costs right from day one,
during the entire life cycle of the
building.
Intangible Benefits
Enhanced air quality,
Excellent day lighting,
Health & wellbeing of the occupants,
Conservation of scarce national resources
Enhance marketability for the project.
11. Conclusion
•
Green Buildings are dynamic environments that
respond to their occupants’ changing needs and lifestyles.
•
“Greener building” can be achieved using
intelligent technology and that this “greening” will provide a tangible and
significant return on investment.
•
With the convergence of urbanization,
globalization and rapidly changing and expanding economy, using these green
building concepts will help the world as well as India in satisfying the
shortage of valuable resources and also will prevent environmental degradation.
•
Thus,
Green building provides significant return on investment to contractors, architects and building owners.
