Citylink Building 2

CityLink Building 2 is located in Rocky View County, AB, just outside of Calgary and is a 540,000 square foot spec-built warehouse. The project achieved Zero Carbon – Design Version 2 certification. This significant achievement showcases a commitment by the project team to improve on previous design to reduce energy and GHG emissions to be one of the first ZCB certified warehouses in Western Canada.

The project applied passive design principles to significantly reduce the amount of heating energy required to condition the facility. These measures include a high-performance building envelope including an R-60 effective roof assembly, airtight assemblies and construction, and vertical dock levelers to limit the amount of air leakage at the overhead doors. The building also uses a dual core energy recovery ventilator to provide fresh air into the building. The system recovers heat from exhaust air leaving the building and uses this heat to precondition the incoming fresh air to reduce the heating energy required for this process by up to 85%. Overall, the building showed a 39% reduction in total energy consumption compared to an NECB 2017 baseline.

The building balances to zero carbon emissions using roof mounted solar photovoltaics to generate energy onsite and the use of high-quality carbon offset procurement to offset the remaining emissions. The solar array provides approximately 8% of the building’s annual energy needs on site by generating 173 MWh/year.
