The expertise of AirGreen in commercial HVAC ventilation proved essential in a sensitive context such as the safe reopening of offices in Montreal during the COVID-19 pandemic. While companies in the region—from Montreal to Laval, including Longueuil, the North Shore, and the South Shore—were wondering how to protect their employees while resuming activities, AirGreen was able to offer custom ventilation solutions adapted to the new health challenges.
Responding to the Emergency: The Impact of COVID on Workplace Ventilation
From the start of the crisis, it became clear that poorly ventilated indoor air could promote the spread of the virus. The challenge for many companies was therefore to upgrade their ventilation systems to ensure optimal air quality and comply with the new standards established by CNESST and Health Canada.
At AirGreen, we immediately understood that our role went far beyond simply installing HVAC systems. It was about supporting each client through a safe transition, combining technical performance, regulatory compliance, and peace of mind for employees.
Case Study: Complete Modernization of a Ventilation System in an Office Building in Montreal
In spring 2022, a manager of an office building located on René-Lévesque Boulevard in Montreal contacted us. His goal: to allow more than 150 employees to return to work under optimal conditions while reassuring his staff about the quality of the indoor air.
After a thorough technical inspection, we found that the central ventilation system was outdated, unable to effectively renew the air or filter suspended particles. Several areas of the building suffered from air pressure deficiencies, and the lack of zone control complicated the management of airflow between different floors.
Solutions Implemented by AirGreen
Comprehensive Technical Analysis of the Building
We conducted a load analysis and a complete aerodynamic assessment to determine the best possible configuration, taking into account the architectural particularities of the building. This step identified risk areas, notably windowless meeting rooms and open-plan offices.
Installation of an Energy Recovery Ventilation (ERV) System
We chose to install several energy recovery ventilation (ERV) units from the Venmar Commercial brand, known for their performance in high-density environments. These devices allow the introduction of filtered fresh air while recovering heat from the extracted air, for increased energy efficiency.
Each floor was equipped with an independent ERV connected to a zoned air distribution system, allowing individual control of airflow rates based on actual occupancy.
Integration of HEPA Filters and CO2 Sensors
To meet COVID-19 requirements, we integrated high-performance HEPA filters capable of capturing airborne viral particles. Additionally, smart CO2 sensors were installed in high-occupancy areas to automatically adjust air renewal based on measured concentration.
Results Achieved and Client Feedback
A few weeks after commissioning, the manager reported a notable improvement in air quality, directly perceived by employees. The stale odor had disappeared, drafts were eliminated thanks to precise balancing, and the CO2 sensors provided reassuring real-time control.
The building was able to reopen safely, while complying with current health guidelines. Even better: the installation led to a 27% reduction in energy costs related to ventilation, thanks to the efficiency of the ERVs and automated airflow control.

Other Project Examples Completed in Laval, Longueuil, North Shore, and South Shore
Laval – Medical Office
In a clinic in Laval, we overhauled the entire ventilation system to integrate standalone air extractors and MERV 13 filters. Objective: protect patients and healthcare staff.
Longueuil – Elementary School
We installed smart air exchangers in each classroom, allowing healthy air to be maintained in winter without opening windows.
North Shore – Logistics Warehouse
The integration of air curtains and dual-flow systems helped reconcile worker health and goods preservation.
South Shore – Community Center
We modernized the ventilation system to ensure safe events compliant with current health standards.
Why Ventilation Is Crucial Post-COVID
The pandemic acted as a wake-up call. Now, ventilation is no longer optional but an essential pillar of comfort and safety in all commercial buildings. Improving indoor air quality means reducing absenteeism, enhancing well-being, and meeting social expectations that have become unavoidable.
