AHER*, DR. S.S.PIMPLIKAR** *P.G. Student – M.E. (Construction & Management) **Prof. & Head of Civil Engineering Dept. MAEER‟S Maharashtra Institute of Technology, Pune-38Abstract In today’s age of urbanization the materials and construction practices; optimizes theenvironment is being ignored by human beings. use of on –site sources and sinks by bio-climaticEnvironmental imbalance is produced due to architectural practices; uses minimum energy todifferent activities made by us. Construction power itself; uses efficient equipment to meet itsindustry is doing a massive role in this. While lighting, air-conditioning, and other needs;construction processes and after construction maximizes the use of renewable sources of energy;due to faulty planning, pollution is created as uses minimum energy to power itself; uses efficientwell as lots of natural resources are wasted. waste and water management practices; andWater scarcity is a major problem in front of provides comfortable and hygienic indoor workingsociety even though while using water for conditions. It is evolved through a design processconstruction, gardening and other domestic that requires all concerned- the architect andpurposes proper care is not taken and water is landscape designer and the air conditioning,wasted. In normal constructions proper care is electrical, plumbing, energy consultants –to worknot taken to save energy and energy is not as a team to address all aspects of building andefficiently used. As demand of energy is system planning, design, construction andincreasing rapidly therefore there is excessive operation. They critically evaluate the impacts ofload on big thermal power projects, which adds each design decision on the environment and arriveinto the pollution. The water falling on the roof at viable design solutions to minimize the negativetop is not utilized in normal buildings. The impacts and enhance the positive impacts on thewaste produced in homes is also contributing to environment. In sum, the following aspects of thepollution and in making un sanitary and building design are looked into in an integratedunaesthetic atmosphere. A green building way in a green buildingdesign provides solutions to all above-mentioned Following are the points that possessproblems and contributes in keeping the prime importance in design, construction andenvironment clean and green. The study shows operations of a green building.that Green Buildings are only way to a Proper site planningsustainable future. Efficient use of water Passive design of building 1.

Green building is called energyefficient building or eco-friendly building. 2. Site planning These buildings are called green due to Site planning is the most important fromtheir similarity with trees…as trees generate their design point of view of green building.

It does not normally wind energy into more useful forms, include human excreta. It is generated by usually electricity using wind turbines. domestic, commercial, industrial, Most modern wind power is generated in healthcare, agricultural and mineral the form of electricity by converting the extraction activities and accumulates in rotation of turbine blades into electrical streets and public places. The words current by means of an electrical “garbage”, “trash”, “refuse” and “rubbish” generator. In windmills (a much older is used to refer to some forms of solid technology) wind energy is used to turn waste. Compost is created by the mechanical machinery to do physical decomposition of organic matter such as work, like crushing grain or pumping yard waste. Compost systems confine water. Wind energy is ample, renewable, compost so that it can receive air and widely distributed, clean, and mitigates the create suitable temperatures for proper greenhouse effect if used to replace fossil- decomposition into fertilizer.[1] fuel-derived electricity.
