777 Dunsmuir Gets Retro(fit)

777 Dunsmuir Gets Retro(fit)

Cadillac Fairview said this week it's partnering with Vancouver-based Fēnix Energy on the installation of a geo-exchange system underneath 777 Dunsmuir, the property that includes a 19-storey office tower and Pacific Centre's Holt Renfrew and Sport Chek locations. The project is Canada's first geo-exchange retrofit of an occupied, mixed-use downtown tower. The system, which stores unused heat until it's needed, reducing carbon emissions by up to 85%, will involve drilling 30 boreholes for vertical piping 400 feet into the ground through the parkade. Fear not, tenants: Cadillac Fairview insists a unique drilling system for confined spaces will cause "minimal disruption."
