What does a commercial building energy audit include — and what does it cost to operate without one?
A professional energy audit for commercial buildings in Longueuil goes well beyond a utility-bill review: our engineers conduct a full existing conditions assessment for commercial buildings, cataloguing the performance of every major mechanical and electrical system against current benchmarks and Quebec's NECB requirements. We identify where energy is being lost, through aging HVAC equipment, under-insulated envelopes, or inefficient lighting and electrical distribution, and rank each measure by projected savings and payback period. Owners who operate without this diagnostic baseline routinely overpay on energy costs and miss grant-program deadlines that could offset a substantial portion of their retrofit investment. Learn more about our full range of building engineering and energy efficiency services and how they complement a formal audit mandate.
One of the most immediate benefits of a commercial building energy audit in Longueuil
is that it produces the technical documentation required to qualify for the Hydro-Québec Efficient Solutions Program, which subsidizes eligible mechanical and electrical upgrades for commercial and industrial clients. We manage the full eligibility analysis and qualification process on your behalf, so your team never has to navigate the program's technical submission requirements alone. Explore how we guide commercial clients through Hydro-Québec Efficient Solutions Program qualification
to understand exactly what the process involves and what savings are achievable.
How do audit findings unlock MLI Select financing and Hydro-Québec grants for Longueuil property owners?
Do you provide turnkey project management, or only the audit report and engineering plans?
Our mandate does not end when the audit report is delivered, and for Longueuil commercial clients who want a single point of accountability, we provide full turnkey project delivery covering feasibility studies, HVAC energy audit South Shore Quebec
system design, MEP engineering plans, and construction supervision. Every energy audit for commercial buildings in Longueuil
we perform is designed from the outset as the first phase of a broader improvement program, not a standalone document. Review our MEP building engineering plans for commercial projects
to see how audit findings translate directly into permit-ready mechanical, electrical, and plumbing drawings.

Energy audit commercial buildings Longueuil : a structured process that covers every system
Building owners who commission a formal audit gain a technical baseline that supports both immediate retrofit decisions and long-term capital planning. Our multidisciplinary team delivers the following core components on every commercial mandate.
Mechanical systems assessment : Our OIQ-member engineers evaluate HVAC equipment, heating plant performance, and ventilation rates against current NECB benchmarks to pinpoint waste and size replacement strategies accurately.
Electrical distribution analysis : We audit existing electrical infrastructure, lighting systems, and load profiles to identify upgrade opportunities that reduce peak demand charges and improve overall distribution efficiency.
Plumbing and domestic hot water review : Domestic hot water systems are among the most overlooked sources of energy loss in commercial buildings; our plumbing engineers quantify consumption and recommend equipment upgrades with clear payback projections.
MLI Select energy efficiency assessment : For eligible mixed-use or multi-residential commercial properties, our audit documentation supports CMHC MLI Select applications that unlock 50-year financing terms and monthly payment reductions of approximately 50%.
Hydro-Québec Efficient Solutions Program eligibility screening : We assess whether your mechanical and electrical upgrade measures qualify for Hydro-Québec subsidies and manage the full technical submission on your behalf, from initial screening through final approval.
