The world green building council defines green building as, “a building that, in its design, construction or operation, reduces or eliminates negative impacts, and can create positive impacts, on our climate and natural environment. Green buildings preserve precious natural resources and improve our quality of life.”
Green architecture gives impacts on sustainable construction practice while reducing the harmful effects on the environment and conserving the energy for future use.

Need For Green Architecture
The construction companies produce the second-largest amount of demolition waste and greenhouse gases. Later, when the building is in use, the lighting and air conditioning cause more harmful gas emissions and consumption of electricity. The occupants’ activities also generate a large amount of waste and pollutants, which have a major role in the depletion of resources leading to climate change.
COP 26 – Together for our planet, an initiative by the UN Climate Conference brought together 120 world leaders and riveted on all factors of climate change and came out with many initiatives to prevent climate change and green architecture.
In ted Talk by Elon Musk: The future we’re building – and boring, he explains his future goals for sustainability and the need for it.

Principles Of Building Green
Site Design
Analyzing the site features and designing accordingly and not taking away the essence of the site.
The climatic conditions, vegetation, topography, natural slope, and viewpoints these factors should be taken into consideration for designing a green building.
Water Management and Conservation
Water usage should be minimised during construction and post-construction also to achieve sustainable building. To achieve this, one can install grey water treatment plants and rainwater catchment systems to recycle water, prevent surface runoff, and recharge groundwater through pits and trenches. Using water-efficient appliances such as low-flow showerheads and low flush toilets.
Energy And Environment
For green building, the use of renewable energy should be increased along with low-affected energy sources. Consideration of both active and passive techniques should be done.
Passive Measures
Passive measures like natural sunlight, wind flow, orientation and topography will dramatically reduce the cooling costs of a building. Natural daylight and proper orientation of openings reduce buildings’ electricity needs to accomplish sustainable building.
Active Measures
Green buildings also incorporate energy-efficient lighting, solar panels for electricity, solar heating to reduce the load, and other renewable energy technologies to reduce energy consumption.
Indoor Environment Quality
The indoor environment quality is very essential for the health of the people occupying the space. Using non-toxic and sustainable construction materials for construction will reduce the chances of sick buildings and also increase the productivity of people living. Openings, well-lit and ventilated rooms, less usage of air conditioners will automatically make the space cleaner and healthier.

Materials For Green Architecture
Minimizing the use of non-renewable resources or wasting materials like sand will lead to depletion, and excessive use will create problems for the future. Therefore, the use of recycled materials, renewable, sustainable construction materials, and eco-friendly materials is advisable for a better future.
Green Building Certifying Agencies
Because of climate change, there are a few agencies in India that help a building go green.
GRIHA
GRIHA is an acronym for Green Rating for Integrated Habitat Assessment. GRIHA works on the aspects like energy consumption, waste generation, renewable energy adoption, of a building in all 3 phases of construction- Pre-construction, building planning and construction, and building operation and maintenance.

ECBC
The Energy Conservation Building Code (ECBC) was launched in May 2007 by the Bureau of Energy Efficiency (BEE), Ministry of Power. Its main aim is to establish minimum requirements for energy efficient design and sustainable construction of buildings.
IGBC
The Indian Green Building Council formed by CII to build a sustainable building and environment for all. This council is based out of the CII-Sohrabji Green Business Centre, Hyderabad, which is India’s 1st Platinum rated green building.
Green Building Materials
Recycled Materials
Using recycled construction material is effective for green architecture. Construction and demolition waste can be used effectively in prevention of depletion of over usage of materials. Some examples of these can be recycled bricks, recycled plastics, or even recycled timber.
Steel is the most commonly used recycled material in the construction industry, no residue is left in the demolition site as well.
Other everyday materials, like newspapers and cardboard, can be used for insulation. Concrete is recycled into recycled aggregate concrete and can be used as a natural aggregate.
Renewable Materials
Renewable materials and resources can be used in green architecture. Resources like geothermal energy or solar energy.
Nowadays , there have been many materials related to solar shingles or solar tiles.

Locally Available Materials
Vernacular materials or Eco-friendly or sustainable construction materials should be used. The most commonly used examples are wood, mud, or bamboo.
Bamboo
Bamboo’s strength to weight ratio is like that of timber. It is a fast-growing plant. Bamboo can resist more tension than compression.The fire resistance is very good because of the high content of silicate acid. Bamboo is used in scaffolding, doors and windows, walls and roofing too.

Rammed Earth
This technique has been used since civilization as a green building material. It is affordable and can be used in construction of foundations, floors and even walls .There are many firms in achieving this technique and making it popular. One such example is Hunnarshala Foundation, Bhuj.
Hempcrete
It is a concrete like material but it is lightweight and a latest addition to the construction industry. It is especially planned to be used to construct walls, floors, and roofs. Its biggest property is that it is CO2 Negative , it absorbs more CO2 than it emits. Another enormous advantage of hempcrete is that it can be recycled by adding a plus point to green building material.
Its use has already been started in India. In Uttarakhand, a startup is using hemp fibre to build a house.

Projects on Green Architecture In India
Hand in Hand India, Kanchipuram
Firm-Green Evolution
The aim was to design a sustainable learning centre in Kanchipuram on a linear site showcasing the ideology of hand in hand.
The design methods followed were:
- From the very start, the conservation process was started by preserving the topsoil at the time of construction.
- Site analysis was done and accordingly the challenge of linear site was used as an advantage to provide openings in the wind’s direction.
- A centrally located courtyard to provide ventilation and shade and exposed hollow clay block walls for energy efficiency and, provide aesthetics.
- Low water fixtures for preserving water.

Bamboo Research And Training Institute, Chandrapur
Firm-SHIFT


The campus is designed by using locally available bamboo and not mainstream materials like bricks and concrete. The excavated soil was used to create rammed earth walls while the structural elements like column, beam and roof are from bamboo. The bamboo used is treated and, through research and experimentation, this structure is designed .
