A Strategic Energy Shift for a Commercial Building in Laval
In today’s context, where energy transition is essential, converting an outdated oil heating system to a high-performance electric solution is more than an upgrade—it’s a strategic decision. In Laval, the AirGreen team recently completed an exemplary project in a mid-sized commercial building. This installation not only highlights our expertise in commercial HVAC, but also our ability to transform aging infrastructure into modern, eco-friendly, and cost-effective systems.
Project Context: An Aging Building Heated with Oil
The building in question, located in Laval’s industrial sector, housed several small businesses in spaces spread over two floors. The central oil heating system, installed more than 30 years ago, was not only energy-hungry but also increasingly unreliable. Between high maintenance costs, frequent breakdowns, and excessive energy consumption, the owner was looking for a long-term, energy-efficient solution that met current environmental standards.
Conversion Objectives
The client’s goals were to:
-
Completely eliminate oil usage from the building.
-
Reduce the annual energy bill.
-
Improve thermal comfort for tenants.
-
Take advantage of available grants for energy-efficient upgrades.
-
Minimize business disruption during the work.
The Solution Proposed by AirGreen
After a thorough assessment of the building’s needs, we recommended a central electric HVAC system based on a high-efficiency central air-source heat pump, paired with top-tier air handler units.
We selected a Bosch BOVA 5-Ton (60,000 BTU) system powered by the BOVA-60HDN1-M20G heat pump, a unit compatible with R-454B refrigerant, known for its low environmental impact and high energy efficiency. This ENERGY STAR certified unit features a SEER rating of 20.5 and an HSPF of 10.5, making it fully eligible for government rebate programs.
Installation Steps: Flawless Project Execution
1. Safe Removal of the Oil System
Removing the old oil system required coordination with multiple trades, including the evacuation of a 1000-litre tank, decontamination of the mechanical room, and disassembly of the outdated boiler.
2. Preparing the Mechanical Space
We reconfigured the mechanical room to accommodate the new units, updating ventilation, electrical supply, and existing ductwork. All electrical work was completed in compliance with the Québec Building Code.
3. Installing the Bosch Central Heat Pump
The outdoor heat pump was installed on an elevated concrete slab, with protection against snow and ice. The indoor unit was mounted in the mechanical room, with an optimized ductwork layout to ensure even heat distribution throughout the building.
4. Control System Integration
We integrated a Bosch Connected Control BCC100 smart multi-zone thermostat, allowing the owner to manage temperature across all rented spaces, remotely and in real time.
Challenges Faced and Solutions Delivered
Electrical Supply Capacity
The building wasn’t initially configured to support the electrical load required by such a high-capacity heat pump system. We coordinated with Hydro-Québec to upgrade the main panel’s power supply, preventing any overload issues.
Tenant Operations Continuity
To minimize disruption, all work was performed outside of business hours, on a schedule spread across two weeks. No complaints were received, and tenants were able to continue their operations uninterrupted.
Results: A Fully Successful Conversion
Since the installation’s completion, the benefits have been clear:
-
43% reduction in heating costs compared to the previous winter.
-
Enhanced thermal comfort thanks to even heat distribution.
-
Zero direct CO₂ emissions, fully eliminating fossil fuel use.
-
Access to a $7,200 rebate through Hydro-Québec’s LogisVert program.
