What is green?
The voluntary pursuit of any activity, which encompasses concern for energy efficiency, environment, water conservation, use of recycled products and renewable energy is defined as green.

“Green” and “Business”
are two sides of the same coin
There are tremendous benefits in adopting Green Concepts. Some of the benefits are:
“Green” corporate image can leverage access to local and International markets
“Green” activities result in reduction of operating costs and improve profitability
Being “Green” can attract environmental conscious customers

What is Green Building?
A Green building is one, which incorporates several green feature, like:
Effective use of existing landscapes
Use of energy efficient and eco-friendly equipment
Use of recycled and environmental friendly building materials
Quality indoor air for human safety & comfort
Efficient use of water
Use of non-toxic & recycled materials
Use of renewable energy
Effective controls and building management system

Why Green Buildings?
The growing trend world-wide is to go for green buildings, which offer a plethora of benefits like lower operating cost, better indoor air quality, enhanced human productivity and reduced environmental impacts

The typical energy cost in a building varies from 60 80%. The saving potential in going for a green building could vary between 40 50% depending on the architectural design, selection of building materials, adopting best practices during construction and occupancy.

Green Buildings- The future

A report from Singapore about:
Energy efficient building involves the planning, design, management and use of a building. In order to ensure that a building is optimally efficient, we have to ensure that the entire value chain in the life cycle of a building is integrated, balanced and coordinated. Otherwise, the objectives of a major investment in a building to create a conducive and functional indoor space to meet human need will not be achieved.
Energy efficient building is not a new development. It has come about through the energy crisis of the 70s. But the energy efficient buildings of the 70s have
contributed significantly to the sick building of the 80s and 90s owing to the very fine tuned designs and poor maintenance.
Hence the energy efficient buildings of the new millennium have to be human centred buildings designed to support the healthy, creative and quality life
style of its occupants. A balanced and totally performing building is therefore required.
Buildings
A. Building envelope OTTV of air-conditioned building. The OTTV for the gross area B. Roof OTTV of air-conditioned building. Where the roof is provided with skylights or any other materials, which allows the passage of light through,
the OTTV for the gross area of the roof shall not exceed 45W/m2.
C. Maximum thermal transmittance for roof of air-conditioned building. For any other type of roof not mentioned in (b) above, the average thermal transmittance for the gross area of the roof shall not exceed the prescribed limits shown in the table 1 below.
