Multi-Phase Strategic Decarbonization
Rideau Towers

Modern City


In its commitment to realizing optimal value in their real estate assets, Morguard embarked on a comprehensive financial analysis to understand the cost, value, and opportunities for driving CapEx and OpEx savings in their planned major mechanical replacements.


The Rideau Towers were scheduled for a complete boiler replacement, providing Morguard with the opportunity to delve into the specification, sizing, and operational efficiency of the proposed design. Morguard’s goal was to understand the real HVAC load requirement for each building and explore mechanical optimization measures that would facilitate a more energy-efficient boiler design and support their ongoing decarbonization efforts.

This pragmatic review aimed to prioritize optimizing the operational efficiency of each building to drive energy conservation and decarbonization, effectively reducing the size and carbon footprint of new mechanical investments.
