Global warming, air, water and sound pollution are just some of the visible impacts majorly in commercial real estate in India. Perhaps one positive that came out of the pandemic was that the carbon footprint on the globe reduced considerably, which brings Green Building concepts in India.
But as countries and economies are gradually getting back to their Pre-COVID operational efficiency, governments at all levels must maintain the climate momentum with long-term strategies.
India is placed 3rd,
after China and Canada, in Leadership in Energy & Environmental Design (LEED) by the US Green Building Council.
Yet, just 5% of the country’s buildings are green, earmarking a sizeable opportunity for green buildings.
What Is A Green Building?
A green building is an environmentally sustainable structure, which makes efficient use of land, materials, energy and water, while costing less in terms of maintenance charges.
A green building enhances energy efficiency, limits water consumption and makes maximum use of recycled and locally available, recyclable and non-toxic materials. It also generates as little waste as possible during the construction process.
A green building involves methods, resources and skills with the sole aim of reducing the negative impact on the environment.
Advantages of Green Building
There are three advantages that go into making a building green. Let’s see what these are:
— Healthier Buildings : By using toxin-free building materials, lowering indoor pollution and having better ventilation and natural light.
— Economical Advantages : Because it uses locally available materials, and uses renewable sources of power like solar, hydro and wind.
— Environmental Advantages : Like improved air and water quality, reduced carbon emissions.
The advantages of green architecture are countless. According to TERI estimates, if all buildings in Indian urban areas are made to adopt green building concepts, India can save more than 8,400 megawatts of power, which is enough to light 550,000 homes a year!
Fundamentals Of A Green Building
There are five essentials that go into making a building green. Let’s see what these are and how they are implementable:
— Sustainable Site Design : Preserve key environment elements create minimum urban spread and minimise needless destruction of urban land.
— Water Quality And Conservation : Preserve natural water cycle of the area. Develop and implement water harvesting to minimise dependence on local supply.
— Energy and Environment : Maximize the use of renewable energy and other low impact energy sources. Building performance should exceed minimum International Energy Code (IEC) compliance level by 30-40%.
— Indoor Environmental Quality : Utilize the best possible conditions in terms of indoor air quality, ventilation, and thermal comfort, access to natural ventilation and day lighting.
— Materials and Resources : Maximize the use of recycled materials and resource efficient composite type structural systems as well as sustainably managed, biomass materials.
Green Buildings Concepts In India
The market for green buildings in India is just scratching the surface. While only 5% of the buildings that can be called green, the market in India is expected to double by 2022, which will be valued between USD 35-50 BN.
According to the Indian Green Building Council (IGBC), India has achieved 7.17 billion sq ft of ‘Green Building Footprint’.
According to the Leadership in Energy & Environmental Design (LEED), Maharashtra ranks first in green buildings in India, followed by Karnataka, Haryana, Tamil Nadu and Uttar Pradesh.
It says that there are almost 6,000 green projects and over 5.77 lakh acres of large development projects in the country, helping to achieve the 75% of the green building footprint target, two years before the actual target date.
