what is green building concept in India? Green building is a resource-efficient construction method that creates healthier buildings that have less environmental impact and lower maintenance costs. This sustainable approach to construction considers the entire life cycle of a building: siting, design, construction, operation, maintenance, renovation and demolition (see Life Cycle Assessment for more information).
Green buildings concept in India are an everyday need to conserve resources and protect the environment from further degradation. Depletion of natural resources and rapid development have led to harmful effects on the environment. Implementing green building technologies and materials can reduce the carbon footprint of real estate.
What is a green building?
A green building is an ecologically sustainable structure, in sync with nature, which efficiently uses land, materials, energy and water while costing less in terms of maintenance fees. A green building increases energy efficiency, reduces water consumption and makes maximum use of recycled, recyclable and non-toxic materials. During the construction process, there is also as little waste as possible. Green building involves methods, resources and skills that are cohesive throughout construction company, with the sole aim of reducing the negative impact on the environment.
What are the characteristics of green buildings?
Green buildings optimize sustainability, not only through their construction company, but also through their operation and maintenance. Green buildings combine knowledge and expertise in the production of walls, roofs, waste management, rainwater harvesting and thermal comfort to save energy and reduce environmental risks.
Green buildings are energy and water efficient
Energy efficiency is one of the most distinctive features of a sustainable building. A green building should be energy and water self-sufficient through renewable energy sources and rainwater harvesting. In addition to solar panels and energy-efficient lights, the building design should make optimal use of daylight and have effective ventilation and sufficient thermal mass to regulate internal temperatures. All of this reduces the need for artificial lighting and air conditioning, thus reducing the energy demand of the building.
It connects with nature
Most green buildings have space for greenery to help people connect with nature. In addition, trees can improve air quality by removing atmospheric carbon dioxide, absorbing pollution and producing oxygen. Trees in the vicinity can also reduce the temperature. Green buildings can integrate spaces for agriculture and food growing within the building complex, through kitchen gardens, roof gardens or backyard gardens.
Green buildings and sustainability
Green buildings use local and renewable materials such as clay, sand, stone, bamboo, etc. to minimize the carbon footprint. Waste materials generated during development are recycled into new materials or composted for reuse. Effective solid waste management during and after construction is a must. Even after occupancy, green buildings concept in India offer efficient waste management systems, such as the separation of wet and dry waste, to further reduce the negative impact on the environment.
Advantages of an ecological house
- Environmental Protection
Green buildings benefit the environment, its inhabitants and society as a whole. Real estate development is one of the largest consumers of natural resources (water, energy and raw materials) and creates a huge amount of waste and pollutants. Studies show that buildings consume 40% of the world’s energy annually. Green buildings remove the burden on the environment by using fewer natural resources. Through their sustainable design, construction and operation, green homes reduce carbon emissions, energy consumption and waste generation while conserving water and reducing exposure to toxins.
- Low maintenance and operating costs
Green house designs are created with energy and water conservation in mind. Owners can thus save on water and energy bills. Green houses are much cheaper to manage in the long term and throughout the life cycle of the building, as they significantly reduce water requirements and energy consumption for lighting and air conditioning.
- Better health
People who live in green buildings have many health benefits because materials that are harmful are not used in their construction. Green construction companies, for example, avoid products that release toxic materials. The indoor air quality is therefore often much better than in ordinary buildings.
According to the World Health Organization (WHO), respiratory and lung diseases associated with poor indoor environmental quality are three of the five leading causes of death. The properties of green buildings have a positive effect on health and well-being. A healthy house in a green building offers a natural defense against respiratory diseases. Research also shows that people who work in green buildings are happier, healthier and more productive compared to people who work in conventional buildings. Incorporating the natural environment into buildings has a positive effect on the psychological, physical and social well-being of residents.
Green Building Council and Certification
When buying a green home, make sure the building has been certified under one of these systems.
The LEED rating (Leadership in Energy and Environmental Design) is a globally recognized green building certification system. In India, rating systems that promote green buildings are Green Rating for Integrated Habitat Assessment (GRIHA), Indian Green Building Council (IGBC) and Bureau of Energy Efficiency (BEE).
Green Building Concepts in India
The green building market in India is currently in its infancy, with only 5% of buildings classified as green. India’s green building market is expected to double to around 10 billion square feet by 2023, worth between $35 billion and $50 billion.
According to the Indian Green Building Council (IGBC), India has achieved 7.17 billion square feet of ‘green building’. It says there are nearly 6,000 green projects and more than 5.77 lakh acres of major development projects in the country, helping to achieve the 75% green footprint target of buildings two years ahead of the actual target date.
According to the LEED (Leadership in Energy and Environmental Design)-GBC India survey, Maharashtra ranks first in green buildings in India, followed by Karnataka, Haryana, Tamil Nadu and Uttar Pradesh.
Greater awareness of green buildings and their long-term benefits will promote green building construction. The COVID-19 pandemic has made people aware of health, well-being and comfort, and homeowners increasingly prefer to live in buildings with better ventilation systems, ample daylight and fresh water.
