The Best Projects of Eco-Skyscrapers of 2021



The Best Projects of Eco-Skyscrapers of 2021

Eco-Skyscrapers: Cities generate about 70% of acidic colourless gas emissions into the atmosphere, while forests and trees absorb about 40% of this volume. The situation needs to be improved; otherwise, we will end up in a situation where it is impossible to live on this planet. In order for green spaces to purify urban air more efficiently, we need to have more trees in the centres of megacities.

Architects can do this thanks to VR and virtual staging solutions from Between 2009 and 2014, 80- and 112-meter high-rise residential complex Bosco Verticale was built in Milan, Italy, with 800 trees and 5,000 shrubs being a part of the project. This is already a good step to green and ecological building, but the industry shouldn’t stop there. The next step is the construction of eco-skyscrapers, each of which will be equivalent to a grove of thousands or tens of thousands of trees. These towers will help cities get rid of smog and prevent global warming. In 2021, some architectural firms from Chicago and Paris surprised the world with their revolutionary concepts of green skyscrapers. So keep reading what is going to happen on the construction site soon.

#1 – Urban Sequoia

The Chicago-based architecture firm Skidmore, Owings & Merrill (SOM), which designed the world’s tallest Burj Khalifa in Dubai, again attracted global attention in November 2021 by announcing the invention of a new type of skyscraper. It is named Urban Sequoia, as the tower’s designers were inspired by the sequoia, the tallest tree in the world. The building will take CO2 from the atmosphere and use it to produce biomass.

This phenomenon usually creates problems in multi-story buildings as air flows on the lower floors only and rushes up the elevator shafts or stairwells like a chimney. Architects usually try to prevent this. However, SOM will deliberately increase the thrust effect in the “core” of its skyscraper so that the circulating air affects the biomass more intensively.

The Urban Sequoia Tower will photosynthesize different types of plants, including trees, but algae will be the main purifier of the air. They will fill the transparent reservoirs on the facade of the building and will be pumped through the pipes inside the skyscraper, like blood vessels. Architects believe that plants can be used to produce building materials, food, and energy.

The developers estimate that the Urban Sequoia skyscraper will be able to capture up to 1,000 tons of carbon per year, which is the equivalent of 48,500 trees. But the parameters of the City Sequoia are not fixed – the towers can be built of any size.

According to SOM, all the technologies proposed in the Urban Sequoia project already exist and are being applied in construction. In the near future, the Bureau plans to start construction of a prototype building in order to test the performance of its systems in practice.

#2 – Mandragore New York

In January 2021, the Parisian architectural bureau Rescubika published a video presentation. In it, they proposed to install the tallest in the United States and the most environmentally friendly tower in the world in the center of New York on the empty Roosevelt Island. This residential skyscraper will be able to absorb more CO2 than it will emit and will serve as a kind of “funnel,” drawing in carbon dioxide from the atmosphere of Manhattan.

The project is named Mandragore New York as the tower’s designers were inspired by the natural shapes of the mandrake. The root of this plant often takes on a human form, with arms and legs. So the winding building will remind people of their connection with nature and the need to live in symbiosis with it.

According to the project, the height of Mandragore New York will be 737 meters. The skyscraper will have 160 floors, 36 wind turbines for clean energy production, 7,000 sq. m. solar panels, and a huge number of green spaces. There will be around 1,600 trees, 8300 shrubs, and 24,500 square meters. m. walls made of living plants.

A geothermal air conditioning system known as the “Canadian Well” will be built into the foundations of the skyscraper. With such a structure, Mandragore New York will allow using the heat of the earth for passive heating in winter and cooling in summer.

Mandragore New York will also be promoting the concept of “energy sobriety.” The building will motivate people to change their lifestyles in order to reduce their carbon footprint. In particular, the skyscraper is expected to provide co-working spaces and home offices in apartments so that residents can work comfortably right in the building. Complex residents will not have to waste their time and energy travelling around the city.
