Optimizing energy performance in a sports facility is no small feat, especially when it comes to maintaining consistent comfort in large, high-traffic spaces. On the South Shore of Montréal, a sports complex was facing ongoing issues with unstable temperatures, excessive energy consumption, and frequent breakdowns with their outdated HVAC system. At AirGreen, we were called in to design a complete heating and cooling solution that met the facility’s technical demands while ensuring long-term efficiency and comfort.
Complete HVAC Modernization: A Tailored Approach
During our first technical visit to this sports center located in Saint-Hubert, on the South Shore, our specialists immediately identified several key issues:
-
Outdated and noisy heating units, unsuited for the building’s large air volume.
-
An air conditioning system with limited performance, unable to evenly regulate temperatures in high-activity zones.
-
High energy consumption with no intelligent management system in place.
Our mission: design, supply, and install a modern HVAC system, high-performing, energy-efficient, and eligible for government grants—one that could meet both the building’s technical constraints and the client’s expectations for comfort and sustainability.
Installed Equipment: Commercial Central Heat Pump – Lennox Energence Model
We recommended and installed the Lennox Energence Ultra-High Efficiency Central Heat Pump—a robust, rooftop solution perfectly suited for busy commercial buildings. This 20-ton modulating unit, operating with R-410A refrigerant, is known for its high energy performance.
Key Technical Features:
-
Inverter compressor technology: continuous modulation for consistent thermal comfort.
-
Seasonal Energy Efficiency Ratio (SEER) above 18 and heating COP above 3.5, exceeding commercial energy efficiency standards.
-
Lennox Prodigy 3.0 smart controller for remote system management, maintenance alerts, and real-time adjustments based on occupancy.
-
Compatible with heat recovery ventilation systems (HRV), which were also installed to enhance indoor air quality.
Installation Details: Precision, Speed, and Coordination
Planning and Engineering:
Before installation day, our technical team carried out a full 3D mapping of the ductwork, taking into account varying ceiling heights and the high-use sports areas (weight room, multi-sport courts, damp locker rooms).
We then coordinated the work schedule to align with the center’s operating hours, ensuring minimal disruption to users.
Key Steps:
-
Removal of the old rooftop unit using a specialized crane, with safety perimeter secured.
-
Structural setup of the new Lennox unit, including platform reinforcement and anti-vibration mounts.
-
Connection to the duct network and centralized control system, including smart integration via a touchscreen interface.
-
Full commissioning, performance testing, and custom training for the sports center staff on using the new system.
Challenges Faced and Solutions Delivered
One of the major challenges of this project was the limited access to some duct areas hidden above hard ceilings. Thanks to our experience and specialized tools, we were able to:
-
Use inspection cameras and compact access tools to avoid unnecessary demolition.
-
Carry out targeted modifications to the duct network, significantly improving airflow in previously underserved areas.
Additionally, our team proposed installing a CO2 sensor linked to the ventilation system, which now automatically refreshes indoor air based on real-time occupancy—a critical factor for comfort and safety in sports environments.
Results: Enhanced Comfort and Energy Savings
After just three weeks of use, the facility’s manager reported:
-
Stable and uniform temperatures throughout the entire building, even during peak hours.
-
A 35% reduction in monthly energy consumption, compared to the same period last year.
-
A notable drop in service calls and maintenance issues, thanks to the reliability of the Lennox unit and our preventative maintenance.
Grant Eligibility and AirGreen Support
This project was eligible for financial assistance under commercial energy transition programs offered by Hydro-Québec and the ÉcoPerformance Program from the Québec government.
At AirGreen, we supported the client through every step of the grant process, including:
-
Compiling the grant application file.
-
Obtaining the building’s energy performance certificate.
-
Following through until the client received over $7,000 in grants.
