Green skyscraper will have 'steel-like' concrete skin

Green skyscraper will have 'steel-like' concrete skin
Paris-based architect Jacques Ferrier was at the AIA Show in San Antonio earlier this month to show off his latest concept for a “green” mixed-use skyscraper, called Hypergreen.

The design, which was recently submitted for a project competition in Paris, incorporates a curving lattice façade made of ultra-high-performance concrete that will act as the building’s primary structural system. The thin, prefabricated concrete members will free the interior structure from any wind-bracing functions, reducing the number of columns required to support the floor plates.

BD+C Managing Editor Dave Barista talked with Ferrier about his “Hypergreen” prototype in an exclusive BD+C podcast. Download the podcast at:
