What is Green Building? EPA definition: “Green or sustainable building is the practice of creating healthier and more resource-efficient models of construction, renovation, operation, maintenance, and demolition.” More than just installing solar panels on your roof

Why is Green Building Important? 8000lbs of waste are typically thrown into a landfill during the construction of a 2000sqft home The buildings in the INDIA consume more than twice as much energy as all the cars in the INDIA Buildings account for 96 KWh in rural and 288 KWh in Urban of total electricity consumption in the India(Energy outlook @2013) Buildings use 80% of total drinking water consumption in the India Indoor levels of pollution are commonly 2 to 5 times higher than outdoor pollution levels

Our Planning Construction – Reduce the amount of waste generated at a construction site Design – Building design details will help to reduce construction materials, and energy/water requirements when completed Material Selection – Careful selection of construction materials will leave less of an environmental impact

Construction Construction generate 30% of Solid Waste After Build Goal: Reduce / Reuse / Recycle Building design based on standard sizes of materials Buy higher quality to reduce rejects Recycle Renovate an existing building

Building Design Goal: To design the building so that it requires less energy/water and is healthier for inhabitants when it is complete and in use Air ducts for an efficient and healthy air flow Insulation Windows designed for maximum daylight Passive Solar Control Solar Cells Heat Exchanger for climate control system Location Rain water conservation

Materials Goal: Choose materials that have low environmental costs and do not contribute to indoor air pollution Engineered Lumber (recycled and reclaimed material) Doors and Windows (energy and placement) Floor Coverings (recycled with no off- gassing) Roof Materials (Reflective and light) Energy Efficient Appliances

Support for Green Building LEED (Leadership in Energy and Environmental Design) Green Building Rating System Voluntary Government Response Create funds and incentives to encourage green building Help on countries economy. Follow Internet for more Details to make green building.

Conclusion I find that building Green maybe also a matter of environmental concern , healthy and reduce the energy consumption which may help our india better Economic condition. So I request My Amity University also try to make Green building for reduce energy consumptions and Expense Projected image of Amity University Rajasthan
