Objectives
Underscoring Fiera Real Estate’s and Colonnade BridgePort’s mutual commitment to sustainability and carbon reduction, the main objectives for the project went well beyond just finding a reliable and cost-effective system. Three environmentally-focused objectives were set to ensure key sustainability targets for the property could be achieved:
- Equipment does not utilize gas as the heating energy source;
- System must recover and reuse heat energy that would otherwise be lost to the atmosphere; and
- Rooftop space usage must be minimized to provide space for future sustainability initiatives, such as renewable energy generation.
With these objectives in mind, the system selected was an all-electric DX cooled / electric SCR RTU with Energy Recovery Wheel/Ventilator.

Key Considerations
Electrical Capacity
An electric HVAC system requires more electricity than a gas-powered system. Investigation determined that the building’s existing electrical system could support the increased need, avoiding significant time and monetary investment.
Note: 450 March was constructed with greater power capacity than what is standard for an office building of its size, in consideration of specific operational needs of the tenant.
Structural Capacity
At more than 3,000 lbs per unit, electric RTUs weigh significantly more than gas-powered RTUs. It was determined that reinforcement of the roof at 450 March was required to support the additional weight. With the top floor of the building unoccupied, no tenants were disrupted during the construction.

Contractor Selection
This complex project required multiple contractors. To ensure the right contractors were chosen, Colonnade BridgePort used a thorough vetting process to identify service providers with proven track records, ensuring they had the necessary skills and experience to meet requirements. Clear communication, shared goals, and a mutual understanding between the project team and contractors was essential for a successful outcome.
Tenant Impact
The potential impact on tenants was considered at every stage of the project, and while there was little to no disruption to business operations and tenant comfort, Colonnade BridgePort maintained open and timely communication.
