“Pollution is nothing but the resources we are not harvesting. We allow them to disperse because we’ve been ignorant of their value.” – R. Buckminster Fuller

In a world which has always taken nature for granted and humans have exploited the earth, we as Architects have a major role to play on multiple fronts, to reverse the impending catastrophe. As sensitive professionals, we cannot divorce ourselves from social and environmental exigencies. In the past architects have almost always laid the larger focus on building envelope, active and passive energy systems, pure aesthetics or short-term economics of materials.

The latter has not been studied with respect to long term gains and have remained at experimental levels in small sporadic pockets across the globe.

Building materials though are omnipresent. They make up the spaces in which we live, work, study, get well and commute, they create our villages, our cities and our built environment. They have social, cultural, moral and environmental implications and often subconsciously control our behavioral patterns and reactions to a space.

According to World Bank researchers, the world is generating at least 3.5 million tons of plastic and other solid waste per day, 10 times the amount a century ago.

Over the years several experimental technologies have been developed to create buildings that are sustainable, eco-friendly and assisted in the upliftment of the community.

One such example is a floating school in the former fishing village of Makoko, Nigeria that was conceptualized as an answer to the region’s frequent floods. Designed by NLÉ, a firm founded by Nigerian-born architect Kunlé Adeyemi, the Makoko Floating School is a prototype that could be applied to other areas in Africa that face infrastructural and social challenges due to climate change. It uses renewable energy from a solar panelled roof, recycles organic waste and harvests rainwater. The school is Built using local help with sixteen recycled empty plastic barrels as buoys and indigenous bamboo as the framework. The school can now cater to those students, who were previously denied education due to frequent flooding. It can hold 60 to 100 students and is Built with a distinctive 3 storey triangular form that provides stability and balance in heavy winds. The structure can also be adapted for community events, clinics, markets and social gatherings.

This year’s IDC 2020 focuses on these issues and seeks to examine the place and use of discarded and recycled materials in architecture, at the same time keeping in mind community spirit and aspirations of the end users. With its 7th edition IDC wishes to encourage the use of discarded or recycled materials that are endemic to the area due to a prevalent industry or lifestyle. Few of the materials that are currently being explored and propagated as building materials on similar pretexts is Ferrock, which uses wasted steel dust from the steel industry to create stronger concrete. Similarly, wooden pallets are often used to create homes in areas where goods are packaged or around docks

Plastic bricks also have several significant advantages over conventional bricks – they’re thinner and lighter, have insulating properties which are 5 times more than that of standard bricks, and are just as strong. They’re also great at insulating against noise and it only takes 20 bottles on average to make one brick. Each brick helps rid the world of discarded plastic and is cheaper and more fuel efficient to manufacture than conventional bricks. It’s also less energy intensive than recycling the plastic into other forms.

The Design Challenge:

This year’s design challenge involves the use of sustainable strategies produced using discarded or recycled materials. Participants need to identify an area where the availability of discarded material or solid waste is high. The material is then used to propose a structure for the local community that will take into cognizance their immediate needs and encourage the integration of the society as a whole. The proposed structure maybe housing units that offer dignity of living standards, a school a community hall or any other public facility.

Entries will be judged on the innovative use of the material, in the response to the need of the community and the final resolution proposed in the design. The design must exhibit a sensitivity towards the environment and should address the ecology of the area at various levels. After all as architects we believe in the Robert Swan, that “The greatest threat to our planet is the belief that someone else will save it.”
