Case Study: This Montréal Industry Reduced Its CO₂ Emissions Thanks to a New HVAC System

An HVAC Transformation for a Sustainable Future: AirGreen's Experience in the Industrial Sector in Montréal

Reducing greenhouse gas (GHG) emissions has become imperative across all sectors, especially in industries known for their significant environmental impact. At AirGreen, we firmly believe every company can contribute meaningfully to the fight against climate change by optimizing its heating, ventilation, and air conditioning (HVAC) system. This approach was precisely implemented by a major industry located in Montréal, which entrusted us with modernizing their existing HVAC system and dramatically reducing their CO₂ emissions.

Why Modernize Industrial HVAC Systems in Montréal?

The Quebec metropolis hosts numerous diverse industries, each with specific HVAC requirements. Unfortunately, many aging systems still rely on outdated, inefficient, and heavily polluting technologies. The necessity for action is clear:

  • Reduced pollutant emissions: A high-performing system significantly reduces the amount of CO₂ released into the atmosphere.

  • Energy optimization: Enhanced energy efficiency directly lowers operational costs.

  • Compliance with environmental regulations: Montréal, Laval, Longueuil, the North Shore, and the South Shore enforce increasingly strict environmental standards that businesses must follow.

The Initial Challenge: An Outdated and Energy-Consuming HVAC System

During our intervention in this Montréal industry, we found an outdated HVAC system, inefficient and excessively energy-consuming. The problems encountered were numerous:

  • Equipment over twenty years old, operating with refrigerants that have a high environmental impact.

  • Ineffective ventilation causing significant energy losses and poor indoor air quality.

  • Elevated energy costs directly affecting the company's profitability.

AirGreen’s Solution: Installation of a High-Efficiency Industrial HVAC System

To address these complex issues, we chose a complete overhaul of the existing HVAC system, selecting advanced technology specifically designed for the industrial sector. We opted for a central heat pump system by Trane, model Sintesis Advantage CGAF, with a capacity of 50 tons (600,000 BTU), recognized for its outstanding performance in energy efficiency (high SEER rating) and substantial reduction of GHG emissions.

This technology offers several key benefits:

  • R-454b Refrigerant: This next-generation refrigerant has an extremely low Global Warming Potential (GWP), complying with the latest environmental standards.

  • Major energy optimization: Capable of generating energy savings up to 40% compared to the previous system.

  • Grant eligibility: Our installation qualified the business for substantial grants, particularly from Hydro-Québec and the ÉcoPerformance program, significantly reducing initial costs.

Installation Process: Successfully Overcoming Challenges

Our team faced several technical challenges during this transformation:

  • Limited space and logistical complexity: Managing an industrial worksite required a meticulous installation plan without interrupting the company’s operations.

  • Adaptation to existing configuration: Precise adjustments had to be made to existing ductwork to maximize the new system's efficiency.

  • Tight deadlines imposed by the client: Our team adhered to an ambitious schedule, completing the full installation within just two weeks.

Thanks to AirGreen’s technical expertise and our proven experience in similar projects across Montréal, Laval, Longueuil, and both shores, we successfully overcame each of these challenges.

Concrete Results: Immediate Emission Reductions and Significant Savings

Just a few months after commissioning, the results were already visible and measurable:

  • A spectacular reduction of 30% in CO₂ emissions due to increased efficiency and the use of R-454b refrigerant.

  • A significant reduction in monthly energy bills, generating substantial annual savings for the company.

  • Noticeable improvement in thermal comfort and indoor air quality, appreciated by all employees.

These concrete outcomes illustrate the added value of thoughtful investment in industrial HVAC, particularly when choosing innovative solutions such as those provided by AirGreen.

Practical Advice: Avoid Common Mistakes When Upgrading Industrial HVAC

Drawing on our extensive experience in this field, here are some valuable tips for industries considering a similar modernization:

  • Never underestimate the importance of planning: A detailed preliminary study is essential to accurately identify your needs and select the ideal system.

  • Always choose an adaptable solution compliant with the latest environmental standards.

  • Entrust installation to an experienced, local provider: Choose a company that understands local particularities in Montréal and surrounding areas, like AirGreen, to ensure optimal results.
