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

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

ConclusionI 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
