Architecture and design magazine eVolo announced on March 7 the winners of their fifth annual Skyscraper competition. This year's winning entries included designs from France, the UK, Germany and India.

The competition rewards designs which "redefine skyscraper design" through the use of new technologies and an understanding of social demands of the time.

This year first place was awarded to Atelier CMJN (Julien Combes and Gaël Brulé) from France for their "LO2P recycling skyscraper" which is designed to be both a skyscraper and a giant wind turbine built out of scrap metal. The designers wanted to locate the building in New Delhi, India, one of the world's most polluted cities, and use the wind turbine as a means of clean energy generation.

Second place went to Yoann Mescam, Paul-Eric Schirr-Bonnans and Xavier Schirr-Bonnans from France. Their design "Flat Tower" was a dome-like, honeycomb-inspired structure which creates space in a horizontal, not vertical, direction.

The prize for third place was awarded to Yheu-Shen Chua from the United Kingdom who re-imagined the historic Hoover Dam in the United States as an inhabitable skyscraper that combines a power plant with a gallery, aquarium and viewing platform.

The competition was open to design and architectural students from around the world; winning entries were chosen by a jury of industry professionals.

Other architectural design awards include the annual Pritzker prize for architecture. This award honors a living architect that has "produced consistent and significant contributions to humanity and the environment through architecture." According to the website the winner of the award is "announced in the spring ."
