Located in the heart of downtown Toronto, the TD Centre attracts many occupants who commute or would like to commute by bicycle. Cadillac Fairview wabted to create a secure, amenity-rich facility that would encourage and support sustainable, two-wheeled commuting for their tenants. 

The resulting facility has proven highly successful and was recognized for interior design excellence with a 2025 ARIDO Award.

The Interchange supports a shift toward sustainable mobility by making cycling a more convenient and appealing option for building occupants. The facility contributes to reduced traffic congestion, lower emissions, and improved occupant well-being, reinforcing the TD Centre’s position as a leading Class A office complex focused on sustainability and tenant experience.

HH Angus provided mechanical and electrical engineering services for The Interchange, a 9,385 ft² end-of-trip facility located in the TD South Tower at Cadillac Fairview’s Toronto-Dominion Centre. Supporting tenants who commute by bicycle, the facility delivers a high-quality, wellness-focused experience that promotes active transportation and enhances tenant amenities.

The Interchange includes 375 bicycle parking spaces, 260 full-height lockers, and 11 showers, along with secure 24-hour monitored bike storage. Premium features such as hair dryers, clothing steamers, and irons elevate the user experience, while the design prioritizes accessibility, inclusivity, and comfort for a diverse range of occupants.

HH Angus’ scope included the design of all heating, ventilation, air conditioning, plumbing, and sprinkler systems within the facility. The team also provided electrical engineering services to support wayfinding improvements in the underground parking garage, ensuring safe and efficient cyclist access.

A key feature of the project is the integration of the Eddy smart leak detection system, an IoT-enabled water management solution that uses sensors, automated valves, and real-time monitoring to detect leaks and mitigate potential damage. This system enhances operational resilience while supporting the client’s sustainability objectives.

The facility’s HVAC system incorporates a high-efficiency, 100% outdoor air-handling unit with heat recovery and an integrated heat pump. By capturing heat from exhaust air to precondition incoming air, the system maintains strong performance even in extreme winter conditions while improving overall energy efficiency. The compact, integrated design enhances reliability and simplifies installation within the constrained retrofit environment.

Retrofitting the facility within an active underground parking structure required careful coordination and design precision to maintain safe cyclist circulation and meet tight project timelines. HH Angus worked closely with the client and contractors throughout construction to ensure successful delivery.
