Telus 4Telus Garden is a mixed-use development located in Vancouver’s bustling downtown area. Comprising two buildings, one is home to a variety of businesses including the national headquarters of telecommunications giant Telus, and the other consists of luxury apartments. With sustainability a critical consideration, the developers needed a heating and cooling system to meet a high level of energy-efficiency. Having considered a variety of systems, including underfloor heating, specifiers struck upon a solution from Jaga which would add an additional two floors of apartments to the building.


Telus 1Telus Garden is a 22-storey, one million square foot office mixed-use redevelopment project that was designed to meet high internationally recognised standards for environmental sustainability.

The buildings have an energy-efficient heat-recovery system, solar arrays, and rooftop gardens, among other green features. Its environmental credentials were recognised when the Canada Green Building Council awarded the development the prestigious Leadership in Energy and Environmental Design (LEED) Platinum certification – the highest rating a building can receive.

With energy efficiency a key requirement, the developers needed a solution that could work with the onsite district energy system—meaning it must function at low water temperatures and high chilled water temperatures. Furthermore, a compact solution was required which could still promote lasting comfort for building occupants in the rapidly changing Vancouver climate.

After careful consideration, Jaga was chosen as the ideal partner to deliver a fast, sustainable heating and cooling solution for the building.


Telus 3To meet the multiple needs of Telus Garden, specifiers opted to install more than 1900 of Jaga’s Clima Canal Hybrid heating and cooling units throughout the building. The Clima Canals are integrated seamlessly by installing the units into a raised floor around the perimeter of the offices and the apartments. Crucially, the units work perfectly in conjunction with the onsite district energy system to help reduce overall energy consumption.

The Clima Canal Hybrid units feature a continuous aluminum grille with six millimeters of open spacing to prevent even the slimmest high heels from getting caught. Since the unit operates at low-water temperatures, it is able to react quickly to temperature changes, enabling occupants to stay comfortable regardless of internal or external heat loads.

Telus 2In conjunction with the Telus Garden onsite energy system, the Clima Canals help the building to reduce energy demand by an estimated 80 percent. Additionally, since the Clima Canal Hybrid creates a curtain of air between windows and heat generated by the radiator, overall heat loss and condensation are reduced.

Since the Clima Canal Hybrid units are built into the floor, there is no obstruction of the panoramic views of Vancouver the building offers for its occupants. The space saving design of the Clima Canal Hybrid also allows for additional furniture or conference room seating in offices. What’s more, because the developers opted for Clima, rather than underfloor heating, they were able to add an additional two floors of apartments to the building.


Cyrus Kangarloo, Jaga engineer and HVAC system advisor, said: “The heating and cooling system used in this project capitalises on the primary strength of the Clima Canal—energy efficiency. The Telus is a great example of how our products work seamlessly with other energy efficient systems.”
