BIG designed Telus Sky with the aim of creating a building that will use 80 percent less energy than other developments of its kind. The project will seek LEED Platinum certification. The design incorporates a storm water management system that recycles rainwater for toilet flushing and outdoor irrigation, reducing potable water use by hundreds of thousands of gallons per year. Renderings of the new building also reveal an open-air rooftop garden, and public spaces programmed to showcase art works by local talents.
“Downtown Calgary has developed as a typical North American city center with a cluster of corporate towers surrounded by a periphery of low density suburban homes,” said Bjarke Ingels in a statement. “The Telus Sky is an attempt to create a lively mixture of living and working at the intersection of lightrail and arterial roads in the heart of the center, to help create a more varied and walkable city center for Calgary.”
The profile of Telus Sky tapers and twists as it rises. The workspaces occupying the first 32 levels are set on large floor plates. Up the elevation, diminishing floor sizes create slimmer dimensions for the residential spaces, allowing greater access to natural light. At the ground level, an undulating glass skirt encircles the building, providing a canopy for passersby and building occupants. An all-glass structurally glazed curtain wall clads the workspaces, while the apartments feature balconies that jut out from the elevation.
The project is scheduled for completion in the fall of 2017.
