It is the practice of increasing efficiency with which buildings use resources- energy, water and materials-while reducing building impacts on human health and the environment

The Green Building concept is gaining importance in various countries, including India. These are buildings that ensure that waste is minimized at every stage during the construction and operation of the building, resulting in low costs, according to experts in the technology

The techniques associated with the "Green Building" include measures to prevent erosion of soil, rainwater harvesting, use of solar energy, preparation of landscapes to reduce heat, reduction in usage of water, recycling of waste water and use of world class energy efficient practices

A similar concept is natural building, which is usually on a smaller scale and tends to focus on the use of natural materials that are available locally.

Merits & Demerits Of Green Building

Merits Of Green Building
Efficient Technologies
Easier Maintenance
Return On Investment
Improved Indoor Air Quality
Energy Efficiency
Water Efficiency
Waste Reduction
Temperature Moderation
Water Conservation
Economical Construction For Poor
Healthier Lifestyles and Recreation
Improved Health

Demerits of Green Building
Initial cost is high
Availability of materials
Need more time to construct
Need skiled worker

A green building is a structure that is environmentally responsible and resource-efficient throughout its life-cycle. These objectives expand and complement the classical building design, concerns of economy, utility, durability and comfort

Green Building Concept In INDIA

Nowadays, we should make a way to maximize our natural resources and also help our mother earth to get some relief since pollution is everywhere plus the global warming that we are all experiencing. Non-renewable energy is expensive and unsafe but did you know that through green building we can save a lot of energy.
Before that, let's define first the meaning of green building (know also as green construction is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from siting to design, construction, operation, maintenance, renovation, and deconstruction
The importance of this is it lessen the consume of energy and the pollution as well because the more we use nonrenewable energy the higher the risk of pollution.

GOVERNMENT AGENCIES
The following five government agencies promote and rules Green Building concept in India
LEED, GRIHA, TERI, ADaRSH, MNRE
With the projected energy demand, thermal energy is not likely to be a solution and renewable energy can only meet the part of energy requirement. CPWD ensured griha compliance in all future govt. buildings. MNRE (Ministry of New and Renewable Energy) in association with TERI (The Energy and Resources Institute) founded ADaRSH (Association for Development and Research of Sustainable Habitats). It is an independent society for the interaction on scientific and administrative issues related to sustainable habitats in India, founded jointly by Government of India with experts in the domain of sustainability of built environment . ADaRSH promotes GRIHA (Green Rating for Integrated Habitat Assessment) as a design and evaluation tool for green buildings and habitats. IGBC formed LEED rating system to promote the concept of green building.
