The Exchange Hotel & Office Tower
Credit Suisse invested in a hotel and office development in downtown Vancouver consisting of a ten-floor rehabilitation of the Old Stock Exchange Building and twenty-one new floors above. Canada’s first LEED Platinum heritage restoration, the towers house 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 combined the new structure, 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 pumps, peak-load boilers, and fluid coolers. The multiple heating and cooling stages through system integration via heat reclamation and storage result in energy efficiencies and long-term operation cost savings. Other sustainable components include stormwater retention and reuse and solar domestic hot water heating.
Zenith was agile in addressing the methodology and implementation when the building occupancy changed mid-way through construction. This led to re-ordering work and changing the commissioning schedule to accommodate these changes.
