World Green Building Week, organised by PJMT, is an annual campaign that encourages everyone to participate in green building projects. Where they call on the construction industry, policymakers, and the government to act quickly to deliver net zero buildings. The programme has three goals: community, environment, and net zero buildings for economics. PJMT is affiliated with the International Green Building Council and is backed by the National Real Estate Development Association and other important organisations. Each session is led by a rising star in the sustainability field.

Session 1 : New Trends in Sustainable Building Design
 

"If you can change the way you think about buildings, maybe what you will do will change the world"
Mr. Rajeev Talwar, Mr. V Suresh, and Dr. Hariharan Chandra arrive at this event with a wealth of knowledge and insight into what will take place over the week. They discuss the importance of providing pakka houses to people all over India. We must assist and give basic housing to all slums and unregistered residents. There will be no immigrants because everyone will own a home. This is also beneficial to women and children. All of the conveniences will be within easy reach. Green buildings can be rented for as little as 50 rupees per day. Everyone nowadays is concerned about the environment. All structures, whether commercial, residential, or mixed-use, must be green. The architectural form, height, and green plantation must all be considered. An effort must be made, and one may be made, to restore this ecosystem
to its previous state. We must reuse plastics when new materials arrive. We must rely on renewable energy sources such as air and water. We should strive for clean, healthy air and water. To be a responsible citizen, we must recycle on our own property. We need to create more sites where water can be recycled multiple times. Check dams are necessary in rural regions. As a result, the GRIHA rating will encourage us to construct more of these structures.

Session 2 : Passive Cooling Traditional Technologies and A historical Perspective
 

Passive solar architecture is distinguished by the absence of any electrical or mechanical components. The sun's heat creates air motions that can be predicted in well-designed areas. Design features, material selections, and positions that might offer heating or cooling effects are all influenced by Solar heat. Overhangs or shades on south-facing windows, shade trees, thermal masses, and cross ventilation are the most basic passive solar cooling techniques.

Microclimate and site design, solar control, natural vegetation, building form and layout, and thermal insulation are all examples of passive cooling prevention approaches. Natural ventilation, night flushing, radiative cooling, direct radiant cooling, indirect radiant cooling, evaporative cooling, and earth coupling are among the modulation and heat dissipation techniques covered. We gain a better understanding of these strategies by incorporating Indian architecture. Courtyards, which are common in traditional Indian residences and havelis, are an outstanding example of cooling designs. Shading devices like Jaalis and screens were also popular. Natural cooling can be accomplished by blocking solar radiation and so lowering heat transport. Water bodies such as ponds, tanks, rivers, fountains, and reservoirs are another option. Towers with wind catchers were also used, It's a tail-capped tower with one side open at the top facing the direction of the prevailing wind.

Session 3 : Going digital model long infrastructure resilience for sustainable urban development 

​

​

To make your food, you'll need 65-75 percent water. Our requirements and availability are vastly different. Water makes about 70% of our planet's surface, but only 4% of it is valuable to us, namely fresh water. Bengaluru is India's IT capital, and to access fresh water and contact ground level water, you must drill 1200 metres. Rice cultivation in south India necessitates a large amount of water.
We study about how building energy is used around the world and in the United States, as well as how energy is used in residential and commercial buildings. We can now capture any picture device and use it in our work because we live in the digital age. We learn about long cities and their effects on the environment. And how cities can be turned into models using BIM software, and how security can be added to and improved in cities. It assists us in doing analyses and case studies for projects in the area. We also gain a sense of the transportation infrastructure, including ramps and traffic flow. Other digital data of water and storm infrastructure may be found, flooding prone locations can be identified, and integrating thermography and photogrammetry can help collect data on which buildings have troubles and where
insulation fails. Agent-based simulation allows us to see how individuals move across places in order to make more efficient decisions.
As a result, 3D digital models make understanding our structures and communities, as well as their connections with the environment, much easier.
They offer a long-standing method for assessing hazards, resilience, and sustainability challenges at the individual building, neighbourhood, and city scales across a variety of disciplines.

Session 4 - Building Resilience for climate, people and economies 

​

​

This epidemic raises awareness of opportunities to address the climate catastrophe, improve human health and equity, and boost our economies. And building resilience isn't something that can be done in a vacuum or with a one-size-fits-all approach. Buildings account for 38 percent of worldwide energy-related carbon emissions and half of all mined materials. 4 billion people are at risk from climate change, and 91 percent of the world's population lives in polluted areas. By 2050, the world's building stock will have doubled, greatly boosting our sector's effect. Its high demand for natural resources hastens climate change, and inefficient, unhealthy structures have a negative impact on our lives. There are 17 objectives for creating sustainable designs. Affordable and clean energy, climate action, life on land, goal partnerships, good health and well being, clean water and sanitation, reduced inequalities, sustainable cities and communities, decent work and economic growth, industry innovation and infrastructure, and responsible consumption and production are some of the goals. We discover how investing in resilience benefits everyone.
These objectives must be pursued in order to achieve economic progress and a healthy environment.

Session 5 - Simplifying Sustainability for all 

​

​

Sustainability should encompass more than simply buildings; it should encompass our way of life. Sustainability is a journey with various origins but the same objective. Brundtland characterised it as "meeting current requirements without jeopardising future generations' ability to meet their own needs."
It is a lifelong journey undertaken by every individual, community, or stakeholder who begins by doing our part, acting deliberately, caring for the environment, and considering the concepts of conservation and preservation from the heart. We must follow this road and contribute to environmental protection.

In the world's largest countries, we study about sustainability and climate change. We study about various countries' strategies and ambitions. India is a massive country with one of the world's most populous populations. We have the highest rate of resource depletion, thus we must practise green living and make it a habit. Niti Aarogya 2021 teaches us about urban planning capacity.
