On September 23, 2021, Hudson Pacific Properties, in partnership with Blackstone Real Estate, unveiled plans for the addition of a hybrid mass timber 16-storey office and retail development to downtown Vancouver’s Bentall Centre, adding 450,000 ft2 of office and retail space within the complex. Once approved, the new building, called Burrard Exchange, will also be one of North America’s tallest exposed mass timber office buildings. The mass timber construction technique will support the project’s sustainability goals and, upon delivery, its operations are projected to be 100% carbon neutral.

HH Angus is providing mechanical and electrical engineering, IT/communications, and energy modeling consulting services for this exciting new commercial project.

The Burrard Exchange will be Hudson Pacific Properties’ first mass timber development, and builds on the momentum of other mass timber projects in British Columbia. Kohn Pedersen Fox Associates is the design architect and Adamson Associates Architects is the architect of record. Construction is expected to begin as early 2023.

Some interesting aspects of HH Angus’ mechanical and electrical scope of work include:

  • A water-cooled Variable Refrigerant Flow heat recovery system using closed circuit fluid cooler and electric boilers to maintain loop temperature
  • Dedicated Outdoor Air System (DOAS) for ventilation and exhaust heat recovery
  • Minimum ASHRAE ventilation rates exceeded to promote better indoor air quality
  • Reconstruction of major electrical infrastructure from the demolition of the Thurlow parkade to create new electrical, generator and IT rooms beneath the existing tower 4 (enabling works scope)
  • New incoming electrical services, generator and communications infrastructure to serve the new tower
  • Targeting certifications for LEED Platinum, FitWell and Wiredscore
  • The building will be designed to comply with the requirement of the Vancouver Building By-Law for Thermal Energy Demand Intensity (TEDI) and for Greenhouse Gas Intensity (GHGI) reduction - TEDI of 20 and a GHGI target of 3.

One of the special considerations of using timber is that it requires both expertise and unusually close coordination between the M&E designers and the structural designers since, unlike drywall, wood openings cannot be adjusted once cut.

"Our team is excited to be part of this project for a number of reasons," said Kevin O’Neill, Commercial Division Director at HH Angus, "That the project will set a new benchmark for green construction in Vancouver by achieving 100% carbon neutrality and the innovative use of mass timber are key highlights for us. We’re thrilled to be working with Hudson Pacific Properties, KPF and Adamson Associates on this development."

Burrard Exchange adds to HH Angus’ growing portfolio of commercial, healthcare and mission critical work in Vancouver and the broader BC region.
