Turn Your Energy Bill Around with a Commercial Heating Audit: A Strategic Investment for Your Building
At AirGreen, we firmly believe that energy optimization begins with a deep understanding of your existing commercial heating system. That’s exactly what a targeted energy audit of your heating system provides—whether you're in Montreal, Laval, Longueuil, on the North Shore, or the South Shore. Too often overlooked, this crucial step is in fact a powerful secret weapon to uncover substantial savings, improve occupant comfort, extend equipment lifespan, and comply with current environmental regulations.
Why Conduct a Commercial Heating Energy Audit?
A poorly heated building is not only uncomfortable but also expensive to operate. This is especially true in places like Montreal, where harsh winters put systems to the test. An energy audit thoroughly analyzes the efficiency of your current heating setup, identifies weak points, heat loss, incorrect settings, or outdated equipment that consumes too much energy.
What’s Included in a Commercial Heating Audit by AirGreen
At AirGreen, we’ve developed a rigorous and customized methodology for energy audits, tailored specifically to commercial and industrial buildings. Here are the key steps of our process:
On-Site Inspection
-
A complete visual inspection of the central heating and/or forced-air system, including boilers, furnaces, air handling units, thermostats, ducts, and sensors.
-
Thermographic imaging to detect invisible heat loss.
-
Verification of air infiltration rates, often the cause of uneven heating.
Technical and Energy Data Collection
-
Review of electricity, gas, or oil bills over a 12 to 24-month period.
-
Measurement of the efficiency of current equipment, particularly the COP (coefficient of performance) for heat pumps.
-
Analysis of operating hours and energy usage patterns.
Detailed Report and Recommendations
-
Delivery of a comprehensive technical report outlining the problematic areas identified, recommended improvements, and concrete costed solutions.
-
Suggestions for equipment upgrades (e.g., replacing the system with a Bosch BOVA or Goodman R-32 central heat pump).
-
Estimation of available subsidies for energy efficiency upgrades (Hydro-Québec, LogisVert, federal CIIÉE program).
Case Study: A Commercial Building in Laval
We were recently hired to perform a full energy audit for a three-story office building in Laval. The heating system dated back to the 1990s and used an oversized natural gas boiler. Occupants complained about cold zones at the edges of the building, and utility bills had reached alarming levels.
After a comprehensive audit, we found:
-
An imbalance in the distribution of heated air across the floors.
-
Major heat losses through poorly insulated ductwork.
-
A single, poorly calibrated central thermostat, causing overheating in some zones.
Our solution:
-
Installation of a Bosch BIVA IDS Premium R-454B central heat pump, with intelligent modulation to better match real thermal demand.
-
Replacement of the ducts with a variable airflow system.
-
Installation of zoned smart thermostats with remote control capabilities.
Result: 35% reduction in heating costs within the first season, optimal comfort throughout the building, and eligibility for a $9,000 LogisVert subsidy.
The Most Common Mistakes in Commercial Heating
Even experienced building managers can fall into these traps:
-
Replacing equipment without a prior audit, often resulting in costly over- or under-sizing.
-
Overlooking the building’s thermal insulation, which is critical for heating efficiency.
-
Neglecting regular maintenance of HVAC units, reducing their performance and lifespan.
-
Failing to consider building usage patterns, which significantly affect heating needs.
Concrete Benefits of an AirGreen Energy Audit
-
Direct reduction in heating costs (up to 40% in some cases).
-
Enhanced thermal comfort for occupants (employees, customers, tenants).
-
Longer lifespan of heating equipment.
-
Compliance with Quebec’s energy regulations.
-
Easier access to government grants.
-
Improved environmental image for your company.
