When Air Quality Becomes a Driver of Business Performance
In Laval, a manufacturing SME had been struggling for years with a high rate of employee absenteeism due to health issues. Management had tried everything: revised schedules, workstation adjustments, awareness campaigns... but the recurring symptoms reported by staff — headaches, fatigue, dry cough — pointed to a frequently overlooked factor: indoor air quality.
By partnering with our team at AirGreen, this company made a decisive shift towards a custom HVAC ventilation solution, designed to purify the work environment and significantly improve employee health.
An Alarming Finding: Stale Air, Affected Performance
Our initial analysis painted a concerning picture:
-
CO₂ levels above 1,500 ppm in workshop areas,
-
Consistently high humidity over 70%, encouraging mold growth,
-
Elevated VOC levels due to solvents and chemical materials used onsite,
-
Insufficient airflow, with a ventilation system dating back to the 1990s.
The management team, attentive to employee wellbeing, called on AirGreen to perform a comprehensive audit of their HVAC system.
A Professional Solution by AirGreen
Technical Diagnosis and Intervention Plan
Our team carried out a multi-step assessment:
-
Mapping of existing airflow patterns and stagnant air zones,
-
Air sample collection to measure fine particle and VOC concentrations,
-
Analysis of the air extraction and renewal system.
The conclusion was clear: the system no longer met even the basic standards for a healthy industrial work environment.
Installation of a Lennox L-Series Energy Recovery Ventilation System
We selected a Lennox L-Series energy recovery ventilation unit, perfectly suited for medium-sized industrial spaces. Why this choice?
-
Adjustable airflow up to 2,500 CFM,
-
High-efficiency heat recovery, cutting down on energy loss in winter,
-
MERV 13 filters, effectively capturing fine particles and allergens,
-
Connected sensors for real-time monitoring of CO₂ levels and humidity.
The system was installed without disrupting production operations, thanks to carefully planned work executed over three days, scheduled during off-peak hours.
Result: A Transformed Company
Data collected two months after the installation was striking:
-
CO₂ levels reduced to 650 ppm across all production zones,
-
Noticeable reduction in dust and airborne particles,
-
Immediate improvement in thermal comfort, even during the coldest months,
-
30% reduction in sick leaves, confirmed by the company’s HR statistics.
Employees quickly reported a difference: fewer headaches, better concentration, quicker recovery between shifts.
Why This Success Story Is Now a Reference Case in Laval
This project proves that a well-designed industrial ventilation system is not a luxury — it's a strategic investment. In Laval, many companies still operate with outdated, poorly maintained, or undersized systems, often ignored until a serious problem arises.
Common Mistakes We Often See
-
Confusing air conditioning with ventilation: an AC unit does not renew air.
-
Underestimating the impact of chemical pollutants in work zones.
-
Failing to adapt the HVAC system to evolving production or staffing needs.
Our Recommendations for Companies in the Region
-
Have your ventilation system inspected every 3 years,
-
Choose units with high-performance, easy-to-replace filters,
-
Integrate smart sensors to automatically adjust airflow based on occupancy and CO₂ levels,
-
Work with local experts like AirGreen who understand the climate and industrial context of Laval.
