Located in downtown Calgary, this complex consists of two towers and a retail podium plus parkade. Phase I consists of a 40-storey tower, full retail podium, and 4.5 levels of below grade parking. The Phase II tower, with a total of 23 tenant floors is situated above the west portion of the Phase I parking. The project achieved LEED Core and Shell 1.0 Gold rating, setting the new minimum standard for green building design.
Mechanically, each phase is served by independent central plants located in the penthouse levels. A chilled water re-claim loop has been provided on ventilation air systems to reduce energy usage by pre-heating outside air when heating, and increasing chiller efficiencies when cooling is required. The boiler plant features condensing boilers for improved overall plant efficiency. Variable speed pumps and variable speed cooling towers are also included to provide energy savings. Air handler heating coils, and perimeter heating have been designed for low grade heating water temperatures to maximize the condensing boiler efficiency.
