Regulation, field practice and tools: our analysis to help renovation professionals sell and deliver energy retrofits.

On a renovation job, a poorly connected duct can wipe out part of your effort. By taking care with connections, penetrations, and seals, you keep the airflow where it's useful, limit unwanted air ingress, and avoid moisture coming back. The result is a more comfortable home and a simpler commissioning, without repeat rework.

Between occupant comfort, rising bills and callbacks, the question of the right setpoint keeps coming up. As a tradesperson, what you really need is a simple benchmark, but one based on the actual home, its insulation and heating system, not a magic rule. With a few quick checks, you can protect comfort and avoid unnecessary overconsumption.

When a slab-on-grade floor stays cold, it's often what's dragging down comfort and running the heating longer than it should. In a retrofit, insulation is also decided by site details: substrate preparation, perimeter continuity, moisture management and thermal bridges. With a clear method and the right materials, you secure performance and avoid costly rework.

On a job site, a few extra or fewer centimetres can change everything. Your job is to find the sweet spot between real gain, budget, and installation constraints, without oversizing just to "do better." Here we help you decide quickly and cleanly, with a field method that also speaks to the client.

When residents stay in place, every day of works counts. By framing the living areas, schedules and clean circulation routes from the start, you limit dust, noise and back-and-forth, without slowing down execution quality. A few simple rules and solid communication are often enough to avoid tension and unforeseen issues.

On a ground floor, the right choice is often decided on site, not on paper. From below, you save time if the crawl space or basement is accessible. From above, you secure the finished floor level and the thermal bridges, provided you anticipate thresholds, doors, and services.

On a facade, colour isn’t just a style choice. It’s also a concrete lever to limit overheating, improve summer comfort, and cut down on complaints about rooms that get too hot — without touching the insulation. As a tradesperson, you can guide your clients toward a colour choice suited to the climate, the orientation, and the job site’s constraints, with a result that’s visible right away.

With a tight budget, your clients mainly expect quick wins, visible on their bills, without getting lost in ten different work items. Your value lies in making a simple diagnosis, treating first the points that leak the most kWh, then planning the rest in coherent stages. You secure comfort and performance, without overpromising or oversizing.

On site, the framing material quickly changes the game for insulation. With wood, you manage thermal bridges and repairs more easily, while with metal, you need to anticipate much stronger conduction and more demanding airtightness details. By setting the right habits from the design stage, you secure performance and avoid callbacks.

When you treat a wall, it's not only the insulation thickness that matters. How the surface exchanges heat through radiation can change how a room feels, limit cold-wall effects and improve comfort without adding to the job. Understanding this parameter and its effect on finishes helps you make safer choices, explain things better to the client, and avoid vague promises about the expected 'gain.'

When you're estimating heat loss on a project, pitch changes the picture. For the same ground-level footprint, the actual exposed surface area increases, and your measurements, choice of insulation and quantities need to follow. By getting the right factor from the outset, you protect the quote and avoid discrepancies at the end of the job.

On site, the real challenge is comfort that holds up over time, not just a fast temperature rise. When you work with wall mass, everyday use and sequential use don't call for the same material choices or the same settings. Handled well, this lever helps you smooth out variations, avoid overheating, and deliver a result that's felt from the first few days.
