Buildings and homes (or the built environment) affects natural environment. Buildings, where people spend 90% of their time, adversely impact human health. Buildings also account for 40% of energy and 16% of the water used annually worldwide. Air quality inside buildings is 2 to 5 times worse than outside There are many factors to consider while studying the impacts of buildings Land use and ecosystems where buildings are built Materials and practices used to construct buildings Material, chemical, energy and water resources used to maintain and operate buildings Demolition and waste of a building at the end of its life Green Building involves minimizing these negative environmental and human health impacts and enhancing positive results throughout the buildingâ„¢s entire life cycle. In addition to environmental benefits, through integrated design, they can be constructed at the same or lower cost than conventional buildings. Typical Features of Green Buildings are *Eco-friendly Building Materials *Green Power *Water use Efficiency *Energy efficient and Eco-friendly equipment *Indoor Air quality

pl send more details about the topic Green Buildings.

green building is an outcome of a design philosophy which focuses on increasing the efficiency of resource use ” energy, water, and materials ” while reducing building impacts on human health and the environment during the building's life cycle, through better siting, design, construction, operation, maintenance, and removal Though green building is interpreted in many different ways, a common view is that they should be designed and operated 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 environmental degradation

ABSTRACT
In India there is a small but growing movement towards the design and construction of ‘‘green’’ buildings. To ensure continued growth in the adoption of green building technologies it is important to ensure that customer needs are being addressed and that claims of performance are warranted; this means evaluating the performance and life-cycle costs of new green buildings as they come on line. ‘A Green building should create delight when entered, serenity and health when occupied and regret when departed’ – Perhaps this is one of the most inspiring definitions of a Green building, articulated in the book ‘Natural Capitalism’.
Construction Industry in India is one of the rapidly growing sectors and contributes significantly to the Nation’s economy. The sector contributes to 10% of India’s GDP .Indian construction sector is growing at a rate of 9.2% as against the world average of 5.5%. The sector is likely to record higher growth in the coming years.
The Indian materials and equipment manufacturers are now faced with a challenge to seriously look at green features to meet the growing demand for Green Buildings. A few green materials and equipment are available in the country. To name a few - Fly-ash cement, Fly-ash block, Recycled Aluminum, Recycled steel, Recycled tiles, Low VOC paints, Bamboo based products, HFC based high efficiency chillers, Building Controls, Green Roof, Recycled wood, etc.,
KEY WORDS: Green Buildings, Fly Ash, Recycled Aluminum,Green Roof….
INTRODUCTION
DEFINITION OF GREEN BUILDING
Green buildings are sited, designed, constructed, and operated to enhance the well-being of their occupants and support a healthy community and natural environment.
Green building is a loosely defined collection of land-use, building design, and construction strategies that reduce the environmental impacts that buildings have on their surroundings. Traditional building practices often overlook the interrelationships among a building, its components, its surroundings, and its occupants. “Typical” buildings consume more of our resources than necessary and generate large amounts of waste.
GREEN BUILDING BENEFITS
• 30% to 40% reduction in operating cost.
• Health and safety of building occupants.
• Incorporate latest techniques and technologies.
• The most tangible benefit is in reduction of operating energy and water costs right from day one during the entire life cycle of the building.
GREEN BUILDING FEATURES
Green Building Have Many Advantages & Features. Some
Important Fractures are indicating below.
• Energy efficient equipment for air conditioning and Lighting systems.
• Use of onsite renewable energy.
• Measurement and verification plan to ensure energy &Water savings.
• Reduction of building footprints to minimize the impact on environment.
• Installation of high efficiency irrigation methods and selection of vegetation which have low water consumption.
• Controls and building management systems.
• Recycling of construction debris to other sites.
• Use of building materials having a high recycled content.
• Use of rapidly renewable materials.
• Declaration of site as “Non-smoking” area or havedesignated area of smoking.
• Providing daylight and views for the occupied areas.
GREEN BUILDING MOVEMENT IN INDIA
The Green Building movement has gained tremendous momentum during the past 5 years, ever since the Green Business Centre embarked on achieving the prestigious LEED rating for their own center at Hyderabad.
The ‘Platinum Rating’ for the Green Business Centre building has sensitized the stakeholders of the construction industry. Today, several corporate and Government organizations are considering Green Buildings in a major way. This has resulted in a spurt in the demand for green materials & equipment. From a humble beginning of 20,000 sq.ft of green footprint in the country in the year 2003, to a staggering 70 million sq.ft till date, green buildings are well poised to reach scalar heights.
Today a variety of green building projects are coming up in the country - residential complexes, exhibition centers, hospitals, educational institutions, laboratories, IT parks, airports, government buildings and corporate offices.
Today the earth’s environment is in a sorry state. Wherever one looks, we encounter pollution. Forests are disappearing. The green patches in the city are being replaced by concrete buildings. Waste products are being dumped indiscriminately. Water is too toxic to drink. The air is unfit to breathe. Global warming has become a menacing issue. There is a question mark over the survival of life on the earth. The human race is at the brink of a self-created disaster. Truly there is a surfeit of environmental problems today.
"Sustainable development is development which meets the needs of the present without compromising the ability of future generations to meet their own needs."
Need for sustainable alternatives:
 Steel, cement, glass, aluminium, plastics, bricks, etc. are energy-intensive materials, commonly used for building construction. Generally these materials are transported over great distances.
 Extensive use of these materials can drain the energy resources and adversely affect the environment.
 On the other hand, it is difficult to meet the ever-growing demand for buildings by adopting only energy efficient traditional materials (like mud, thatch, timber, etc.) and construction methods.
Technology for Alternative:
Materials for low cost Housing should be:
 Energy Efficient
 Environment Friendly
 Employment Generating
Green architecture may have these characteristics:
 Energy-efficient lighting and appliances.
 Water-saving plumbing fixtures.
 Landscapes planned to maximize passive solar energy.
 Minimal harm to the natural habitat.
 Alternate power sources such as solar power or wind power.
GREENBUILDING PRACTICES:
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.
E.g. Using sunlight through passive solar, active solar and photo voltaic techniques and using plants and trees through green roofs, rain gardens, and for reduction of rainwater run-off.
SALIENT FEATURES
• Minimal disturbance to landscapes and site condition
• Use of Recycled and Environmental Friendly Building Materials.
• Use of Non-Toxic and recycled/recyclable Materials.
• Efficient use of Water and Water Recycling
• Use of Renewable Energy
• Indoor Air Quality for Human Safety and Comfort
• Effective Controls and Building Management Systems
