Mastering ventilation: the key to a high-performing learning environment
At AirGreen, we understand that indoor air quality is not just a matter of comfort—it’s a crucial factor in focus, health, and academic performance. This is especially true in Montréal’s private schools, where modern HVAC installations have become a new standard—not only to meet post-pandemic health requirements, but also to offer the ideal environment for learning. In this article, we unveil the behind-the-scenes of several projects completed by AirGreen in these educational institutions, and how well-designed ventilation can truly make a difference in academic results.
An underestimated issue: classroom air quality
For years, the issue of ventilation in schools was pushed to the background. However, international studies clearly show a direct link between air quality and cognitive performance. Too much CO₂ in the air, airborne particles, poorly controlled humidity—and students’ ability to concentrate drops significantly.
In Montréal, several private schools became aware of this issue and contacted AirGreen to conduct a full HVAC system assessment.
Case study: intervention in a private college in Outremont
In 2023, our team intervened in a well-known high school located in Outremont. Built in the 1980s, the school had never upgraded its ventilation system. The result: overheated classrooms in winter, window condensation, and a feeling of stale air by the afternoon.
Technical diagnosis
After conducting a certified indoor air quality analysis, we observed:
-
CO₂ levels exceeding 2,000 ppm in some classrooms.
-
Insufficient air renewal, especially in science and music rooms.
-
Relative humidity reaching 70% during the winter.
AirGreen solution: a central energy recovery system
To meet the specific needs of the school, we proposed and installed a Venmar EVO5 700 HRV central energy recovery air exchanger, capable of managing the air volume of the entire academic wing.
Equipment features:
-
700 CFM airflow, ideal for high-density environments.
-
78% heat recovery efficiency, minimizing energy loss.
-
MERV 13 filters, capturing allergens, airborne viruses, and fine dust particles.
-
Programmable smart control panels by zone.
-
Eligible for LogisVert and Environment Education grants.
Custom HVAC installation: precision, discretion, and compliance
Our team completed the work during school holidays to avoid disrupting classes. The installation was completed in three weeks and included:
-
Full replacement of outdated air ducts.
-
Installation of silent diffusers in each classroom.
-
Connection to a centralized control system via tablet.
-
Room-by-room airflow balancing based on actual occupancy.
A final air-tightness and energy performance test validated the system’s compliance with Ministry standards.
Results: measurable improvements to the school climate
Just a few months after commissioning the new system, school administrators reported very positive outcomes:
-
Decrease in absenteeism related to respiratory infections.
-
Improved classroom attention, confirmed by multiple teachers.
-
Enhanced thermal comfort, with no overheating or cold zones.
-
18% reduction in annual energy costs.
An internal survey even revealed that 92% of students and staff found the air “fresher and more pleasant” than before.
The impact of ventilation on academic success
By ensuring consistent, controlled air quality, schools empower their students to:
-
Maintain optimal concentration levels throughout the day.
-
Reduce headaches, fatigue, and respiratory discomfort.
-
Learn in an environment that promotes calm and motivation.
Testimonial from the administration
“Thanks to AirGreen, we transformed our school without needing major renovations. The team was professional, fast, and attentive to our constraints. Our students and teachers genuinely feel the difference.”
