Originally built in the 1970s and home to Global Affairs Canada, we are proud to be involved in the modernization of this building which focuses on employee wellness, universal accessibility, and environmental sustainability. The retrofit included a complete gutting of the interior base building and IT, as well as modernizing building elements such as plumbing, electrical, and heating/cooling systems. There was a significant focus on maintaining the heritage aspects and characteristics of the original building while also achieving energy efficiency goals.
Dialog was the lead Architect and Engineer for the design. Based out of Toronto, they partnered with associate architect McRobie Architects and Interior Designers and associate engineer Goodkey, Weedmark & Associates in Ottawa. The General contractor was Ellis Don, and the Mechanical contractor was Modern Niagara – completing both the plumbing and HVAC scopes of work.
HTS designed and sold the majority of the mechanical equipment on the job. This consisted of the following:
- 2x Haakon DOAS units – shipped in sections to fit through an opening in the existing structure
- 3000 ft. of Jaga Strada perimeter convectors – custom-designed to meet heritage aspects of the original building while updating the heating system to low temp H2O
- 180x Jaga horizontal fan coils – providing a low-profile design with EC motors for energy efficiency
- 9x IEC fan coils to serve computer and elevator control rooms
- DriSteem Electric Humidifiers installed in each DOAS
- Cook Fans
- B&G pumps and hydronic specialties.
- Danfoss VFDs
- Sigma Unit Heaters
Subsequent phases of renovation in the garage area of the complex also included the following:
- Tempeff Energy Recovery Units
- Daikin Semi-Custom Air Handling Units
HTS Toronto worked with the mechanical consultant very early in the design to select the proper equipment for the project. They took into consideration elements such as heritage requirements including sound, limited space, and overall look. After the extensive design, the job was tendered and awarded to HTS Ottawa, where the HTS Ottawa team project managed the job to completion.
