A CVAC innovation in the heart of Montréal
In a dense urban environment like Montréal, indoor air quality is a crucial issue for occupant health — whether in offices, retail spaces, or residential buildings. At AirGreen, we recently implemented a connected ventilation solution in a downtown commercial building, designed to detect and correct the presence of invisible pollutants in real time, often responsible for fatigue, headaches, respiratory discomfort, or drops in productivity.
This project reflects our vision of a smart, responsive, and eco-conscious HVAC system, capable of adapting to ambient air fluctuations and the day-to-day realities of modern buildings.
The context: new offices, but no comfort
Our client, a fast-growing tech company, had just moved into brand-new offices near boulevard René-Lévesque. Despite a central ventilation system that complied with building codes, many employees reported respiratory discomfort, recurring headaches, and a feeling of “stuffy air” by the end of the day.
An initial audit by another firm failed to clearly identify the issue. That’s when the company called on us for an advanced assessment of the indoor air quality and the building’s HVAC ventilation system.
The AirGreen approach: connected analysis, smart sensors, and adaptive ventilation
Our methodology is built on three pillars:
-
Continuous detection of invisible pollutants
-
We installed a series of connected sensors throughout the building (meeting rooms, open workspaces, server room).
-
These sensors measure real-time levels of CO₂, VOCs (volatile organic compounds), fine particles (PM2.5), temperature, and humidity.
-
-
Data correlation with human activity
-
Using a monitoring platform, we were able to correlate occupancy data with spikes in pollution. For example, CO₂ levels spiked during meetings, without any corresponding adjustment in ventilation.
-
-
Dynamic optimization of the ventilation system
-
We integrated an intelligent control module into the existing ventilation system, capable of adjusting airflow rates based on detected pollutant levels.
-
The result: an adaptive HVAC system that responds in real time to the actual needs of the space.
-
The results: comfort restored and purified air around the clock
In less than 10 days after commissioning, the client observed:
-
A significant drop in employee complaints about air quality.
-
A CO₂ level reduction of over 40% during peak hours.
-
A noticeable improvement in focus and productivity, according to team supervisors.
-
A 12% energy savings thanks to ventilation modulation based on real-time needs.
This intervention was praised by company leadership as a quick, discreet, and highly effective solution, delivered without having to replace the existing system.
Why adopt connected ventilation in Montréal and surrounding areas?
In a vibrant and densely populated city like Montréal, indoor pollutants come from multiple sources:
-
Outdoor pollution (traffic, industry).
-
Construction materials (paints, glues, insulation).
-
Electronic equipment and printers.
-
Human presence and collective respiration in poorly ventilated rooms.
A traditional constant-flow ventilation system can’t effectively respond to these variables. That’s why connected ventilation is becoming a logical evolution of modern HVAC systems.
What we accurately measure and correct
Here are the key indicators monitored by our system:
-
CO₂: the core indicator of confined air.
-
VOCs: released from building materials and cleaning products.
-
PM2.5: fine particles harmful to the respiratory system.
-
Temperature and humidity: to maintain thermal comfort.
As soon as one of these metrics exceeds the recommended threshold, the system automatically adjusts to restore a healthy balance.
