Improving energy efficiency in industrial buildings through custom HVAC solutions
In the industrial sector, energy management is a critical issue. At AirGreen, we recently demonstrated how a well-thought-out HVAC strategy can completely transform a company’s energy footprint. This article highlights a project we completed at a North Shore logistics warehouse, where installing a high-performance HVAC system allowed us to cut energy costs by 50% in just one year, while ensuring consistent indoor comfort for employees and preserving temperature-sensitive goods.
The challenge: an energy-hungry, uncomfortable warehouse
This large warehouse located in an industrial zone on the North Shore of Montréal was equipped with an outdated heating and cooling system, unable to meet seasonal demands effectively. In winter, employees complained about the cold despite sky-high heating bills. In summer, the heat made working conditions difficult and compromised the preservation of certain stored products.
The property owner contacted us with two clear objectives:
-
Improve indoor thermal comfort for the staff.
-
Significantly reduce the annual energy bill, while meeting environmental standards and maximizing access to available subsidies.
Technical analysis and tailored recommendations
We began with a comprehensive energy audit of the warehouse, assessing surface area, insulation, occupancy cycles, internal heat sources (equipment, lighting), and thermal leaks.
Key findings:
-
Poor heat distribution during winter (localized overheating and cold zones).
-
No intelligent zoning for cooling.
-
No mechanical ventilation control.
-
An old, inefficient and costly gas system.
We recommended installing a central heat pump system with intelligent zoning, using multiple Bosch BOVA-60HDN1-M20G units (60,000 BTU), paired with smart thermostats and occupancy sensors to adjust temperature based on zone usage.
System selection: efficiency, durability, and subsidy eligibility
The Bosch Inverter BOVA system was selected for its smart modulation technology, compatibility with intelligent controls, and excellent performance rating (SEER 18, HSPF 9.5). This system maintains high efficiency even in extreme cold — a major asset on the North Shore, where winters are harsh.
Key advantages of the Bosch system:
-
Variable-speed modulation for reduced energy consumption.
-
Capable of heating down to -25°C without electric backup.
-
Low noise level, ideal for industrial buildings.
-
Eligible for Hydro-Québec’s LogisVert rebate program.
Installing these units made the project eligible for over $12,000 in subsidies, significantly offsetting the initial investment.
A complex installation, expertly handled by AirGreen
Installing HVAC in an active industrial building is always a challenge. We planned the project carefully to minimize disruption to operations, working during off-hours, evenings, and weekends.
Key steps in the project:
-
Safe dismantling of the old gas system.
-
Installation of new rooftop and ventilation zone heat pump units.
-
Creation of a galvanized steel ductwork network with reinforced insulation.
-
Configuration of smart thermostats by zone, adapted to the specific needs of each operational area.
-
Comprehensive verification of airtightness, airflow, volumes, and unit performance.
Our team also trained the staff on how to use the new system and perform simple preventive maintenance, reducing long-term service costs.
Measurable results: lasting savings and outstanding client satisfaction
One year after the installation, the results exceeded expectations:
-
50.3% reduction in annual energy costs (heating + cooling).
-
Significant improvement in comfort for employees, year-round.
-
Fewer internal complaints about extreme temperatures.
-
Reduced carbon footprint of the warehouse.
The client is now considering the addition of solar panels to complement their long-term energy strategy and has already asked us to study a second building.
What this project reveals: AirGreen’s commercial HVAC expertise
This project shows our ability to combine energy performance, thermal comfort, and ROI, even in complex industrial environments. Thanks to our deep knowledge of top-tier HVAC products like Bosch, Lennox, Fujitsu, Gree, and Trane, we design custom solutions that align with our commercial clients’ operational and budgetary constraints.
Tips for North Shore businesses looking to cut energy costs
-
Have your current system assessed: many industrial facilities waste energy unnecessarily.
-
Consider intelligent zoning: you may be heating unused areas.
-
Take advantage of available subsidies: programs like LogisVert offer significant funding for equipment upgrades.
-
Choose an expert partner like AirGreen: our experience in commercial HVAC on the North Shore, Montréal, Laval, and Longueuil is well-established.
