How a Laval Shopping Center Optimized Its Energy Performance with AirGreen
At AirGreen, we understand that large commercial buildings come with unique challenges when it comes to energy efficiency, thermal comfort, and HVAC system profitability. Recently, we had the privilege of transforming a shopping center located in Laval, on the North Shore of Montréal, by installing a brand-new high-performance central air conditioning system. This strategic upgrade allowed the property owner to triple the building’s energy efficiency while significantly reducing operating costs.
Here is a detailed case study of this ambitious project that highlights our technical expertise, our tailored approach, and the measurable results we achieved.
An Urgent Need to Modernize the HVAC System
The shopping center in question, built in the 1990s, was still equipped with an old central air conditioning system running on R-22, a refrigerant now banned. The system, inefficient and energy-consuming, struggled to maintain a consistent temperature in high-traffic areas. Tenant complaints were mounting, and electricity costs kept rising with each summer season.
The owner contacted our team for a comprehensive assessment of their HVAC system, with the following goals:
-
Improve indoor comfort for both customers and tenants.
-
Reduce annual energy costs.
-
Take advantage of available government grants in Laval.
-
Comply with current environmental regulations.
Energy Audit and AirGreen's Custom-Designed Solution
Our first step was to conduct a full energy audit of the building:
-
Analyzing current energy consumption.
-
Inspecting ventilation systems and existing ductwork.
-
Measuring heat loss and evaluating the system’s efficiency.
Following this analysis, we recommended a full system replacement with a Bosch BOVA36HDN1M20G / BOVB36HDN1M20G central heat pump, operating with the new R-454B refrigerant, which is much more environmentally friendly.
This high-efficiency 36,000 BTU central heat pump, paired with a compatible Bosch air handler, offered an impressive seasonal performance (SEER 21 / HSPF 10), ideal for the demands of a commercial space.
Key Installation Steps in Laval
The project was carried out in several phases over two weeks to avoid disrupting the shopping center’s business activities:
1. Logistical Planning
-
Coordination with building managers and tenants.
-
Fast-track acquisition of municipal permits in Laval.
-
Scheduling deliveries outside of business hours.
2. Removal of the Old System
-
Safe dismantling of indoor and outdoor units.
-
Eco-friendly recovery and disposal of the R-22 refrigerant.
3. Installation of the New Bosch System
-
Placement of the outdoor unit on a concrete slab.
-
Connection to the upgraded ductwork network.
-
Integration with the building’s existing smart control system.
4. Testing and Commissioning
-
Verifying pressure levels and airflow.
-
Calibrating smart thermostats.
-
Training building staff on optimal use of the new system.
Immediate Results Observed After Installation
Just weeks after commissioning, the results were striking:
-
66% reduction in electricity consumption tied to HVAC usage.
-
Noticeable improvement in indoor comfort across all commercial zones.
-
Complete elimination of complaints regarding ambient temperature.
-
Access to a $3,260 LogisVert grant, through Laval’s energy transition program.

Expert Advice: What to Know Before Modernizing Your Commercial HVAC
Choose the Right Capacity (BTU)
Incorrect sizing can lead to frequent breakdowns and energy waste. Always rely on experts for an accurate assessment.
Don’t Overlook the Ductwork
Outdated duct systems can limit energy savings—even with the best equipment.
Plan During the Off-Season
Commercial HVAC projects are easier to schedule in the fall or spring, when equipment availability and install teams are more flexible.
