Winners of evolo’s 2011 skyscraper competion

eVolo magazine has run a tidy little competition for the last five years, inviting architects to innovative new skyscraper typologies. Today, the winners of the 2011 Skyscraper Competition were announced and we’ve got a recycling wind turbine, an energy- and water-harvesting horizontal tower, and a re-imagining of the Hoover Dam.

FIRST PLACE: ‘LO2P Recycling Skyscraper’ by Atelier CMJN (Julien Combes, Gaël Brulé)

“The idea behind this skyscraper is to recycle the old cars and use them as building material for the new structure. The building is designed as a giant lung that would clean New Delhi’s air through a series of large-scale greenhouses that serve as filters. Another set of rotating filters capture the suspended particles in the air while the waste heat and carbon dioxide from the recycling center are used to grow plants that in turn produce bio-fuels.”

SECOND PLACE: ‘Flat Tower’ by Yoann Mescam, Paul-Eric Schirr-Bonnans, and Xavier Schirr-Bonnans

Imagined for medium-size cities where vertical skyscrapers do not fit the skyline, the flat tower is a “new high-density typology that deviates from the traditional skyscraper. The medium-height dome structure is perforated with cell-like skylights that provide direct sunlight to the agricultural fields and to the interior spaces. The dome’s large surface area is perfect to harvest solar energy and rainwater collection.”

THIRD PLACE: ‘Reimagining the Hoover Dam’ by Yheu-Shen Chua, United Kingdom

This project merges the programs at the current Hoover Dam — viewing platform, a bridge, and a gallery – into a “single vertical super structure.”
