At the foot of Yonge Street, Pinnacle One Yonge is a multi-tower development near the Toronto waterfront. With a phased site development of towers ranging from 65 to 95-storeys, and numerous other nearby high-rise developments on the horizon, it was critical to understand how the wind effects would evolve over time. Particularly for the taller of the towers at Pinnacle One Yonge, careful consideration must be given to building design and performance with respect to wind loads.
