The Exchange Tower
Credit Suisse invested in a thirty-one-storey office development in downtown Vancouver consisting of a ten-floor rehabilitation of the Old Stock Exchange Building and twenty-one new office floors above. Canada’s first LEED Platinum heritage restoration, the towers houses three levels of retail, ten levels of tenant improvement hotel, and twenty-one levels of leasable office.
Originally built in 1929, the project demolished the existing systems within the original eleven levels and combining the new structure, both extending the floor plate and raising another twenty levels above.
Some key sustainability components include highly efficient hydronic heating and cooling through integrated geo-exchange thermal, water source and air source heat pump, and peak-load boilers and fluid coolers. The multiple stages of heating and cooling through system integration via heat reclamation and storage will result in the benefits of energy efficiencies and long-term operation cost savings. Other sustainable components include storm water retention and reuse and solar domestic hot water heating.
Zenith was required to be nimble in how we addressed the methodology and implementation when the building occupancy changed mid-way through construction. This led to a re-ordering of works and making changes to the commissioning schedule to accommodate these changes.
