Many times we get confused between Green Building and Sustainable building. There is general misconception that both are same, but in reality they differ in their meaning. Sustainability is basically defined as “The ability to meet current needs without hindering the ability to meet the needs of future generations in terms of economic, environmental and social challenges”. A sustainable product lowers pressure on the environment through the use of source materials that are renewable and/or sustainably harvested.
The term Green is relatively simple, for me, Green Buildings are those if they aims at reducing harmful effect on the environment. Hence Green buildings are those who have better improved building design, that uses renewable energy source like wind, solar etc.
For example, a wooden door may be considered as green but it may or may not be sustainable depending on the type of wood. If the wood is harvested from a forest that starts depleting because of the harvesting process, then it is not a sustainable product. On the other hand, if the cutting of trees for wood don’t result in the depletion of forest then it is will be considered as a Sustainable product.
