Energy audit in Quebec: where to start

August 28, 2026 3 min read Greater Montreal

Rising heating bills, uneven comfort from room to room, a building that feels like a sieve: these are the symptoms of an energy-hungry building. An energy audit serves to move from impression to strategy, understanding where the energy really goes, and knowing which measures deliver the best return on investment.

What is an energy audit

An energy audit is a complete analysis of a building’s consumption: it identifies the sources of loss, evaluates the performance of the envelope and systems, and proposes a prioritized action plan, not a wish list, but quantified measures with their return on investment.

Where the energy goes

Losses are often concentrated in the same places: thermal bridges, air leaks, deficient or missing insulation, windows at the end of their life, poorly tuned mechanical systems. This is where thermography becomes valuable: it makes visible the cold areas and heat losses the eye cannot perceive.

The right reflex is not to do everything, it is to do first what pays the most.

Prioritize by return on investment

Improving everything at once is rarely realistic. The value of an audit is precisely to prioritize: sealing air leaks and fixing insulation before replacing a system, for example, because the gain per dollar invested is often higher there. You aim for the efficiency of the capital as much as of the energy.

Grants in Quebec

Several assistance programs exist in Quebec, provincial, from Hydro-Québec, sometimes municipal, to support energy-efficiency work. We help you identify those that apply to your project and prepare the applications.

Grant programs, their criteria and their amounts change over time. Always check eligibility and the conditions in effect at the time of your project, we direct you to the relevant and up-to-date programs.

A three-dimensional gain

Improving a building’s energy performance means winning on three fronts at once: financial (reduced bills), comfort (stable temperature, fewer drafts) and environmental (reduced footprint, a more durable building). It is one of the rare investments that pays for itself while improving quality of life.

Our approach

Boreon carries out energy audits and modeling with an integrated, technical and energy vision, grounded in building science and specific expertise in the envelope. Thermography in support, recommendations prioritized by ROI, and assistance with grant programs. We work throughout Greater Montreal, West Island, South Shore, Laval, North Shore.

Key takeaway

An energy audit turns an energy-hungry building into a clear action plan: where the losses go, which measures to do first (by return on investment), and which grants to mobilize. It is the starting point for a cheaper, more comfortable and more durable building.
