ABSTRACT: Green building, or sustainable design, is the practice of increasing the efficiency with which buildings and their sites use energy, water, and materials, and reducing building impacts on human health and the environment over the entire life cycle of the building. Green building concepts extend beyond the walls of buildings and can include site planning, community and land use planning issues as well. The growth and development of our communities has a large impact on our natural environment. The manufacturing, design, construction, and operation of the buildings in which we live and work are responsible for the consumption of many of our natural resources. In India buildings account for 39% of total energy use 68% of total electricity consumption 30% of landfill waste 38% of carbon dioxide emissions 12% of total water consumption

INTRODUCTION

DEFINITION OF GREEN BUILDING

Green buildings basically mean the environmental friendly buildings, which are constructed in the healthiest way they can be to avoid hazardous impacts on the environment. The resources like land, water, energy etc. are judicially used and the environment goals are set prior from the starting of the construction of such buildings. In other words, they are 'no harm' buildings to the environment.

WHAT IS MEANING OF GREEN BUILDING?

Green building(also known asgreen constructionorsustainable building) refers to a structure and using process that is environmentally responsible and resource-efficient throughout a building's life-cycle: from setting to design, construction, operation, maintenance, renovation, and demolition.

WHAT IS NECESSITY OF GREEN BUILDING?The growth and development of our communities has a large impact on our natural environment. The manufacturing, design, construction, and operation of the buildings in which we live and work are responsible for the consumption of many of our natural resources.

Green building brings together a vast array of practices, techniques, and skills to reduce and ultimately eliminate the impacts of buildings on the environment and human health. It often emphasizes taking advantage ofrenewable resources, e.g., using sunlight throughpassive solar,active solar, andphotovoltaicequipment, and using plants and trees throughgreen roofs,rain gardens, and reduction of rainwater run-off. Many other techniques are used, such as using low-impact building materials or using packed gravel or permeable concrete instead of conventional concrete or asphalt to enhance replenishment of ground water.

While the practices or technologies employed in green building are constantly evolving and may differ from region to region, fundamental principles persist from which the method is derived:Siting and Structure Design Efficiency,Energy Efficiency,Water Efficiency,Materials Efficiency,Indoor Environmental Quality Enhancement,Operations and Maintenance Optimization, andWaste and Toxics Reduction.[10][11]The essence of green building is an optimization of one or more of these principles. Also, with the proper synergistic design, individual green building technologies may work together to produce a greater cumulative effect.On the aesthetic side ofgreen architectureorsustainable designis the philosophy of designing a building that is in harmony with the natural features and resources surrounding the site. There are several key steps in designing sustainable buildings: specify 'green' building materials from local sources, reduce loads, optimize systems, and generate on-site renewable energy.

The making of these eco-friendly buildings fundamentally involves: Proper use of energy and environmental components: Firstly, the environmental components like air, water and natural resources are used in the most efficient way. Mainly renewable energy is used in such constructions. Energy sources, which can result to be harmful for the environment are avoided. Heat recovery ventilators and geothermal heat pumps are used to save energy. Maintenance of the indoor of the buildings: Green buildings assure to be naturally ventilated and ventilating system is such that it does not harm the other neighboring buildings. Smoking areas are tried and constructed outside the building or are build in such a way that the smoke does not affect the environment of any other parts of the building. The use of the daylight is maximized. Biodegradable and natural friendly cleaning machineries are used. Eco-Friendly materials used for construction: The engineers of these buildings try to ensure that the materials and resources used are environmental-friendly. From building materials to the interior furniture, everything is mostly made through recycling of products. 'Waste reduction plans' are carried out by the engineers and team.

Features of Ecological Building and Some TechniquesMany options are now available to those wishing to design and build green buildings or eco-friendly buildings.. Architects, engineers and builders worldwide are now using construction techniques that have been developed throughout human history, in response to local environmental concerns and the physical resource opportunities available, coupled with 21st century technological refinements.These range from rammed earth construction, which involves clay-based material mixed with water and then rammed into brick or solid wall form, suitable in hot and dry climates, to straw bale houses, literally using bales of straw as the core structure. Straw is a great insulator, is a breathable material that filters the air passing through it, and contrary to expectation, is fire-resistant when compressed. And it is low cost.Other options are so-called earth ships, which use recycled car tyres filled with earth as the buildings walls, or Yurts or Gers, the semi-permanent nomadic tents of Inner Asia, that utilise local wood, wool and canvas, to literally live on, with the land. These examples can be seen as development that has a low impact upon the environment, which utilise and blend in with the local environment, and could be dismantled and moved easily.In more conventional building construction, it is how technology and building materials merge and create ecological resources that are the key to green success, as well as using simple and readily available materials. For example, using pulped recycled paper for roof insulation is a simple but highly effective ecological resource. The damage to human health from asbestos insulation, laid out in rollsin thousands of UK homes, is now well-known. Asbestos also takes hundreds of years to decompose in landfill.

Other features of an ecological building might include : The varied use of solar panels for domestic hot water heating, Water conservation, possibly including biological waste water treatment and re-use, and the simple collection and recycling of rainwater for garden use, Low energy lightbulbs, which can last up to 100 times longer than regular bulbs, Cellulose insulation (like the paper in the above example), Non-toxic or lead-free paints and wood preservatives, Locally grown and harvested timber from sustainably managed forests.Green buildings are steadily increasing their footprint in India with an increase from 6,000 sq. m of green space in 2003 to 304,800 sq. m expected by the end of 2008, according to the Indian Green Building Council, which is promoting the green building movement in India. The first green building in India was the CII-SohrabjiGodrej Green Business Centre in Hyderabad. Kolkatas Technopolis lays claim to be the countrys first green building for information technology.

Benefits of Green Building: Environmental Benefits Enhance and protect biodiversity and ecosystems Improve air and water quality Reduce waste streams Conserve and restore natural resourcesEconomic Benefits Reduce operating costs Improve occupant productivity Enhance asset value and profits Optimize life-cycle economic performanceSocial Benefits Enhance occupant health and comfort Improve indoor air quality Minimize strain on local utility infrastructure Improve overall quality of lifeGreen Building Programs LEED, Leadership in Energy & Environmental Design, is the nationally accepted rating system for commercial and institutional green buildings. The program helps establish a standard measurement for green building. Contact the US Green Building Council for more information www.usgbc.org/leed/http://www.usgbc.org/leed/ Green Built NC Homes Certification Program is a state-wide residential green building rating program administered by the WNCGBC. Homes receive a rating and certificate based on third party inspections. 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.As high-performance buildings use less operating energy, embodied energy has assumed much greater importance and may make up as much as 30% of the overall life cycle energy consumption. Studies such as the U.S. LCI Database Project]show buildings built primarily with wood will have a lower embodied energy than those built primarily with brick, concrete, or steel. To reduce operating energy use, designers use details that reduce air leakage through the building envelope (the barrier between conditioned and unconditioned space). They also specify high-performance windows and extra insulation in walls, ceilings, and floors. 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 (daylighting) can provide more natural light and lessen the need for electric lighting during the day.Solar water heatingfurther reduces energy costs.Onsite generation ofrenewable energythroughsolar power,wind power,hydro power, orbiomasscan significantly reduce the environmental impact of the building. Power generation is generally the most expensive feature to add to a building.

ISSUESCost and payoffThe most criticized issue about constructing environmentally friendly buildings is the price. Photo-voltaics, new appliances, and modern technologies tend to cost more money. Most green buildings cost a premium of
