Architectural bureau SOM has presented a project of a building with negative carbon emissions 
Architects from the American bureau SOM have conceived of building an air-purifying skyscraper. The company presented the project of a building with negative carbon dioxide emissions at the UN conference on climate change (COP26), writes Dezeen.
absorb and store carbon – wood and lightweight hemp-based concrete. In addition, systems for direct capture of air emissions will be built into the building. The architects believe that such a high-rise will be able to reduce by 400 percent more carbon emissions in 60 years of operation than will be released into the atmosphere during its construction.
The carbon captured by the building can be sold for further use or recycling, and growing on the facade algae – turn into biofuel for cars, airplanes or heating apartments. According to the creators of the project, all the technologies for the implementation of the project already exist and are used – before the construction of the eco-skyscraper, it remains only to test their combined application in construction.
At the end of October, experts predicted the mass appearance of houses made of biomaterials in the near future – including skyscrapers made of hemp. Other sustainable alternatives to drywall and cement were identified by the architects as wood, earth, lime, mycelium and straw.
