A high-stakes ventilation project led with precision in a high-traffic environment
In the world of HVAC installations, some projects demand a much more strategic, meticulous, and creative approach than others. That’s exactly what we encountered at AirGreen when we were contacted by the management of a large-scale sports complex in Laval, facing major ventilation issues that threatened both the facility’s operations and the comfort and safety of its users. Thanks to our technical expertise, our experience in commercial ventilation, and our ability to design custom-tailored solutions, we not only restored the building’s air quality but also optimized the entire system’s energy efficiency.
The challenges: humidity, lingering odors, and widespread discomfort
The initial call came from the complex’s technical director, located in the heart of Laval, on the North Shore of Montréal. The building, used daily by hundreds of athletes, teams, families, and employees, was suffering from rising humidity problems, persistent stagnant odors, and an uncontrolled interior temperature, particularly in the locker rooms and intensive training areas.
Our first intervention was a thorough inspection of the existing ventilation system, which revealed blocked ducts, an aging air handling unit (poorly suited for the current occupancy load), and a blatant lack of fresh air supply.
Our diagnosis: an outdated system unfit for modern needs
This complex, built more than 20 years ago, still operated with a central ventilation system that had insufficient airflow and no heat recovery, leading to significant energy losses and uncomfortable interior conditions during peak hours.
Our technical team then developed a comprehensive redesign plan for the ventilation system, taking into account:
-
The real occupancy volume of the sports facilities (locker rooms, courts, training rooms, bleachers)
-
The need for constant air renewal to eliminate humidity and odors
-
Smart temperature control to ensure optimal comfort
-
Energy recovery integration to minimize operating costs
The solution: installation of a ventilation system with energy recovery ventilator (ERV)
After consulting with and receiving approval from the complex’s management team, we selected and installed a centralized ventilation system with heat recovery from the brand Venmar CES, model X24HRV, paired with a resized ductwork network.
Technical specifications of the installed system:
-
Airflow capacity: 2400 CFM
-
ERV (Energy Recovery Ventilator) technology, ideal for high-humidity environments
-
High-efficiency filters (MERV-13) to guarantee excellent indoor air quality
-
Automated control system based on ambient temperature and humidity
-
Custom insulated galvanized ductwork designed for each zone of the building
-
Noise-dampening enclosures to preserve quiet in training areas
This system enables efficient energy recovery, using extracted air to preheat or precool the incoming fresh air depending on the season. It drastically reduces operating costs while maintaining a healthy and comfortable indoor environment.
A project completed without disrupting the complex’s activities
One of the major challenges of this project was to complete the entire installation of the new ventilation system without affecting the facility’s sports programming. To do so, our AirGreen team implemented a nighttime and weekend work schedule, ensuring close coordination with the building’s staff.
We also put in place:
-
Temporarily isolated work zones
-
A strict safety plan to eliminate any risk to users
-
Meticulous logistics for bringing in the new ERV in sections into a cramped mechanical room
The result: immediate comfort improvements and full client satisfaction
From the very first hours of operation, the new system provided a drastic improvement in air quality, including:
-
Complete elimination of humidity and sweat odors
-
Significant reduction in indoor humidity levels
-
Even temperature distribution throughout the facility
-
Widespread satisfaction from users and staff
The client reported an immediate increase in traffic at the complex, positive feedback about the improved comfort, and a measurable reduction in monthly energy costs. We also provided a responsive after-sales service, with scheduled check-ups and a custom HVAC maintenance plan tailored to their new infrastructure.

Practical tips for managers of sports or community buildings
Here are some key recommendations for facility managers overseeing similar complexes:
-
Have your ventilation system inspected every 2 to 3 years
-
Regularly monitor humidity levels and air exchange rates
-
Choose ERV or HRV systems to maximize energy efficiency
-
Never underestimate the impact of thermal comfort and air quality on your facility’s attendance
-
Always work with a qualified HVAC installer known for proven results and reliable aftercare
