The building’s form was shaped by analysis of the climate. The tower faces south, curving towards the sun to take advantage of daylight and heat, while maximizing the perimeter for cellular offices with views of the Rocky Mountains.
By turning the convex façade into the prevailing wind, the structural loading is minimized thus reducing the amount of steel required for the inherently efficient diagrid system. Each triangulated section of the structure spans six storeys, providing superior structural efficiency, while helping to visually break down the scale of the building. At the time of completion, it was the first time a triangular diagrid has been applied to a curved skyscraper in North America.
