Algae: The Latest Architecture and News

The building industry is one of the biggest generators of carbon emissions, with some estimates suggesting that 38% percent of all CO2 emissions are linked to this field. As a response to the current crisis, architects, designers, and researchers are taking measures to reduce their carbon footprint during and after construction. Many initiatives and research teams are looking at building materials to find low-carbon solutions and reduce the impact of building materials during production.

One of the most prominent fields of research is concerned with biofacture, the type of process that involves using biological organisms to manufacture materials. By understanding the abilities of organisms such as algae of fungi, alternatives to widely used materials can become carbon neutral or even carbon negative. Other initiatives are researching novel ways to use untapped, yet readily available resources such as desert sand, soil, or waste from demolitions.

As researcher, designer and MIT professor Caitlin Mueller once said, “The greatest value you can give to a material is to give it a load-bearing role in a structure.” Load-bearing components – foundations, beams, columns, walls, etc. – are designed to resist permanent or variable forces and movements. Similar to the bones of a human body, these support, protect and hold everything together. To fulfill that indispensable function, they must be made from materials with outstanding mechanical properties, which explains the prominence of cement and steel in structures. However, their high performance comes at a high cost: together, they account for 15% of global CO2 emissions. This makes us wonder, is it possible for structural materials to be truly sustainable? We know solutions like greener versions of concrete already exist, but there are many other alternatives to explore. And sometimes, the answer is closer than we expect; in the earth beneath us and the nature that surrounds us.

Nature has continually played muse to architects. Colors and forms from the natural world find themselves embedded in artificial edifices. Buildings are also shaped by patterns of the wind and sun, topography, and vegetation. While architecture is informed by the effects of nature, buildings have been proposed as inert objects that remain static in a biologically evolving world. Anthropocentric concrete “jungles” are devoid of life, separating humans from natural environments and causing imbalances that have manifested as pandemics. What would cities look like if there were no boundaries between humans and ecosystems?
