Rapid commercialisation is leading to an enormous increase in the number of construction projects. Construction and even maintenance of buildings deteriorate the environment in ways beyond one can imagine. They increase the carbon footprint on the environment manifold. In fact, out of the total carbon emissions of India, a whopping 22% of it is contributed by the Indian housing sector. In order to curtail this growing concern, sustainable development is being encouraged. Sustainable development implies building green buildings which basically are those which imply a minimum damaging effect on the Earth’s environment in comparison with other buildings. Green buildings use green building materials also known as sustainable building materials or eco-friendly building materials. A few examples are as follows:

Wool bricks have been created with the aim to create bricks that are more eco-friendly, less toxic and have better strength than ordinary bricks. The benefits of these green building materials are that they are 37% stronger than other bricks, they are more water resistant and they do not need to be heated in a furnace like ordinary bricks, hence, less consumption of energy.

Ordinary tiles are made up of either clay or concrete. Also, ordinary tiles are dark coloured which means that they absorb more heat. As a sustainable alternative, technological advancement has now provided us with solar tiles. These green building materials protect the building from the weather and also provide energy to the house.

Concrete releases a high amount of carbon emissions. To combat this, sustainable concrete is being introduced. Sustainable concrete is concrete mixed with broken glass chips, wood chips, slag, etc. Adding these to create green building materials don’t really affect the composition of concrete, and on the plus side, they make them more eco-friendly.

Recycling newspaper and other old paper and using them for insulation in buildings is simple yet revolutionary. The paper is usually mixed with natural products like borax, boric acid, and calcium carbonate to make it fire-proof and insects resistant.
