India is emerging rapidly as one of the leading countries working on planting green building projects. Ranking 2nd after the United States in green technology, the country has already registered more than 4,300 projects which are registered under green technology. Growing at an exponential rate, the market is expected to get double reaching close to 10 billion per sq.ft by the end of 2022.
The building sector is consuming approximately 25 percent of water and 35-40 percent energy apart from the raw materials creating a large number of waste materials during construction, maintenance and deconstruction emitting approximately 40 percent and 35 percent greenhouse gases.
Why go green
The ideal green building project allows preserving most of the natural environment around the project site, while still being able to produce a building that is going to serve a purpose. The construction and operation promotes a healthy environment for all involved, not disrupting the land, water, resources and energy in and around the building. This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort.
Goals of Green Building
The prior goal of the model Green Building is to make the earth a more sustainable place without disrupting the natural habitats.
Benefits
The benefits of Green Buildings range from environmental to economic and social, as new technologies are constantly showing some innovations like composting toilets, rainwater harvesting and LED lighting. Compositing toilets are using an aerobic process for treating waste materials using little or no energy while rainwater harvesting system collects rainwater into deep pits and well. The water can then be used for a variety of purposes from household drinking water to water for the garden or livestock. LED’s are rapidly replacing incandescent bulbs and are great for saving energy as they are much more efficient and have a much longer lifespan. Thus, green buildings play an essential role in controlling the wastage of water and in conserving natural resources. Protection of biodiversity and improved air are other key features of this innovation.
Trends
With the aim of building a sustainable environment, their efficiency can be maximized by the use of various innovative technologies present in our country. Technologies like biomimicry( a concept of imitation of the various systems of nature into building’s design and architecture), and green roofs are already being used to get the best out of green buildings.
These trends are leading to the adaptation of many innovative designs for air ventilation followed by better cooling and heating control. On the other hand, the roof of buildings are getting partially or fully covered with soil and vegetation placed on a waterproofing membrane. Hence, providing moderate heat and cooling followed by an improved air quality.
Standardization of norms and better incentive schemes can certainly help in the growth of green buildings in India accelerate. Having a great market potential, it is required to create awareness about green buildings which carries a long-term benefit with it and can be considered as the future mantra which will lead the foundation of sustainability.
