Sustainable Ventilation in Laval: How a Local Company Cut Its CO₂ Emissions by 50%

A Tailored HVAC Strategy to Green Industrial Operations

In the industrial park of Laval, a company specializing in commercial furniture manufacturing recently took a major step forward in environmental responsibility. Aware of its carbon footprint and aiming to reduce energy costs, the company reached out to AirGreen to redesign its entire ventilation system. The goal: implement a sustainable HVAC solution capable of cutting CO₂ emissions in half, without compromising productivity or employee comfort.

Industrial Ventilation: A Strategic Lever for Reducing Carbon Emissions

In industrial environments, the ventilation system often accounts for a significant portion of total energy consumption. Poor air management not only leads to thermal losses but also results in unnecessary overuse of heating or air conditioning due to non-recovered fresh air intake.

Problems Identified During the Initial Audit

  • No heat recovery in place

  • Constant-speed fans running continuously without occupancy-based modulation

  • Constant airflow system over 20 years old

  • Work zones with fluctuating temperatures and constant discomfort

This situation resulted not only in energy waste, but also high operating costs and uneven temperature distribution across the workshop.

AirGreen’s Intervention: Complete Ventilation System Overhaul

Technical Study and Airflow Modeling

Our engineers began with a thermodynamic analysis of internal airflow, supported by 3D modeling of warm, cool, and stale air circuits. This helped pinpoint loss areas and zones left uncovered by the existing system.

Equipment Installed

AirGreen recommended and installed a Lennox L-Series 600 CFM HRV system, paired with smart air management through sensors and a programmable logic controller (PLC). The entire setup is connected to a remote-access digital interface.

  • High-efficiency ECM motor

  • Counterflow heat exchanger core, with 75% thermal recovery

  • CO₂ and temperature sensors in every zone

  • Centralized control panel with customizable schedules

  • MERV 13 filters to improve indoor air quality

Renovation Work

  • Complete removal of the existing system

  • Installation of new insulated rigid ductwork to minimize thermal losses

  • Integration of zoned ventilation units, independently controlled by production area

  • Three-phase commissioning, to avoid any interruption to business operations

Results Achieved After 90 Days

Energy Performance Indicators

  • 52% reduction in energy consumption related to ventilation

  • 46.8% reduction in CO₂ emissions compared to the previous year

  • Average indoor temperature improved by +3°C in winter without extra energy use

  • Elimination of cold drafts and better comfort distribution throughout the facility

Testimonial from the Technical Director

“Thanks to AirGreen’s intervention, we not only lowered our operating costs, but also improved comfort for our teams. The system is reliable, intelligent, and adapts to activity levels in real time.”

Subsidies and Incentives Received

This project received $7,500 in funding through the ÉcoPerformance program from Énergir, designed to encourage mechanical system upgrades in industrial settings.

Other Potential Grants for Laval-Based Companies

  • Tax credit for energy transition in commercial buildings

  • Local municipal support programs for eco-conscious SMEs

  • Québec government assistance for decarbonization initiatives
