Calgary City Centre


Designed by Zeidler Partnership and BKDI Architects

Calgary City Centre is a 1,000,000 square foot, Class A, 36-storey tower development. It includes an 853,032 square foot office tower sitting on a podium containing street level retail on one side, and five levels of below grade parking with 632 stalls and features a three-storey lobby as the main entrance to the development. The project has achieved LEED Platinum Core + Shell Development.

S + A Services Included:


The building is complete with a high performance envelope in order to reduce energy consumption and minimize the size of the mechanical infrastructure. Design was completed in BIM. Some of the mechanical energy-saving features of the building include three highly-efficient centrifugal water chillers to provide the cooling to the facility and free cooling of chilled water with ventilation air to reduce natural gas consumption. The development has a waterside economizer to produce chilled water to the facility without mechanical cooling. Also, the perimeter radiant heating uses reduced pumping requirements for further electricity savings. The hybrid high efficiency condensing boilers with mid-efficiency force draft boilers maximize the usage of natural gas while providing the required building heat. There are also tenant supplementary cooling systems with induced draft cooling towers to minimize fan horsepower.
