Cadillac Fairview tackles downtown Vancouver CO2 emissions
Quote:
"A key component of our decarbonization strategy is to proactively reduce our consumption of steam," says Derek Hurley, General Manager of Office for Cadillac Fairview's Pacific Centre and RBC Place buildings. "Our priority is to make sure that our buildings today operate as efficiently as possible and that we leverage heat recovery technology to reduce our carbon output."
They're doing it by installing heat recovery chillers and parking a series of thermal energy storage tanks under the Pacific Centre Complex and using them to store excess heat energy recovered from cooling processes, which is required year-round in the complex. That recovered heat will be either redirected to other parts of the complex that require it or stored in the tanks until it's needed.
Completed in early 2025, the project is expected to reduce emissions by up to 3,000 tonnes of CO2 annually. It will also save on energy costs through the reduction of about 53,000 gigajoules annually by 2030.
"Instead of excess heat being run through cooling towers and released into the atmosphere, the heat recovery chillers capture that heat and redirect it to other areas of the complex where it's needed or store it in the thermal energy tanks," says Hurley. "We've specifically interconnected those thermal energy storage tanks between four buildings – 700 West Georgia, 701 West Georgia, 609 Granville, and the retail shopping centre. They're able to draw upon that waste heat in the thermal energy storage tanks and extract it as needed."
