If all Buildings in urban areas were made to adopt green Building concepts, India could save more than 8400 MW of power which is enough to light half of Delhi or 5.5 lakh homes a year according to estimates by TERI. A green building depletes very little of the natural resources during its construction and operation. The aim of a green building design is to minimize the demand on non-renewable resources and maximize the utilization efficiency of these resources when in use and utilization of renewable resources.

Building Planning should minimize the use of building materials and optimize construction practices and sinks by bio-climatic architectural practices; use minimum energy to power itself for the use of equipment and lighting and air-conditioning and lastly maximize the use of renewable sources of energy. It should also use efficiently waste and water management practices; and provide comfortable and hygienic indoor working conditions. It is evolved through a design process that requires all concerned –the architect and landscape designer and the air conditioning, electrical, plumbing and energy consultants – to work as a team to address all aspects of building including system planning, design, construction and operation. Thus, enhance the positive impacts on the environment.

Architects and planners should start thinking green in the planning of Buildings. Integrating living and vegetation with architecture is fast gaining popularity around the world and now a new term “Vegitecture” has been coined for it and it is becoming common. Thus the Architect may think to bring concrete jungles to green jungles through “Vegitecture”.

The Architect can use large windows with Double glass system. The glazed trapping will act as insulating layer of air between the two layers of glass. One of these layers of glass filters and disperses light and heat without reflecting it back outside the building. The air conditioning system will also be less intensive because the double glazing system insulates the building. Further, hollow fly ash bricks can be used in walls during construction. This will also provide good insulating properties apart from using waste materials.

Characteristics of green building

Building construction and its upkeep for livable conditions requires huge energy in lighting, air-conditioning, operation of appliances etc. Green Building i.e. energy efficient building is the one which can reduce energy consumption by at least 40% as compared to conventional building. The cost of constructing energy efficient building is estimated to be 15 – 20% higher as compared to conventional building without energy efficiency. However, this is more than compensated over the period of time i.e during life cycle cost and operation and living. Using green building materials and products, promotes conservation of non renewable resources internationally. In addition, integrating green building materials into building projects can help reduce the environmental impacts associated with the extraction, transport, processing, fabrication, installation, reuse, recycling, and disposal of these building industry source materials.
