Groupe Alfid is a major player in real estate management in Quebec, recognized for its diversified portfolio of residential, commercial and institutional properties.
Located at the foot of Mount Royal, Le Parc is an iconic 19 floors residential complex, offering 365 luxury apartments with panoramic Montreal views. The units, studios, 1-bedroom, and 2-bedroom apartments, include heating, hot water and air conditioning.
Challenges and objectives
The results of our technical audit identify several significant issues for Le Parc apartments.
- Aging domestic hot water boilers
- Unstable fresh air burners, causing freezing in ducts and abnormal temperature cycles.
- Poorly connected pool boilers, causing recurring problems and excessive gas consumption.
- Obsolete control systems, incorrect sequences and absence of critical measurement points.
- Non-optimized HVAC system operation, leading to significant energy waste.
With these findings in mind, the project objectives were clear: sustainably reduce gas and electricity consumption, modernize mechanical assets, stabilize system operation, improve occupant comfort and maximize available subsidies.
Our solution
We designed a turnkey project combining mechanical modernization, energy optimization and control system upgrades, while ensuring reduced operating costs and improved overall building comfort. Measures were selected based on:
- Their energy impact
- Desired reliability and durability
- Their ability to correct non-compliant installations
The entire project allows for an estimated 34% reduction in energy (GJ) and 27% reduction in annual costs, in addition to a complete rejuvenation of the mechanical fleet.
Measures Implemented
01
Lighting modernization (LED)
02
Installation of two air-to-air heat recovery exchangers
allowing a 50% reduction in fresh air heating load.
03
Complete replacement of domestic hot water (DHW) boilers
New, higher-performance Daikin heat pumps (EER 13.3), capable of handling a larger fresh air supply and providing heating and cooling.
04
Variable Frequency Drives (VFDs) and new motors
achieving an 18% reduction in motor consumption.
05
Implementation of centralized control
The project resulted in a modernized building that is brighter, more pleasant and healthier for its users
06
Recommissioning (RCx)
Annual Energy Cost Reduction
Thanks to heat recovery and the modernization of controls for all systems.
Simplified system operation
