Green Building – Definition
A Green Building is defined as a type of building which uses less amount of water, optimizes the energy usage, conserves natural resources, generates lesser waste and also provides healthier living spaces, when compared to a normal conventional building. Generally, the construction materials used in traditional buildings releases harmful substances during their manufacture and also creates health issues whereas green buildings makes use of natural fibre-based insulation and bamboo-based products, etc.
The Green building concept simply aims at reduction of the overall impact the building has on the health of fellow human beings and also on the environment by effectively using the natural resources and preventing environment degradation. A green building is also known as sustainable building which develops structures & processes which are environment friendly and resource efficient throughout lifetime of the building.
Materials Used For Green Building
The selection of using eco-friendly materials and products while constructing a green building plays an important role in the ‘greenness’ of the project. This plays an important role in saving energy and, in turn, reduces the environmental impact of the building. The use of recycled materials in green buildings is a recent phenomenon and has been gaining popularity worldwide, as it is both economical and environment friendly. In India, the introduction of Green building certification has triggered the usage of recycled materials by many developers in the recent times. Using of recycled materials is much beneficial as they are more economical and provides better performance. Few of the recycled materials include
- Fly ash Concrete & bricks – It is a byproduct of coal-fired power plants.
- Cement – Contains waste products like fly ash, slag and silica fume
- Glass – Made of used glass bulbs, window panes and glass bottles etc.
- Aluminum – Made of used window frames and cans etc.
