Pierre-Louis is CEO and co-founder of Argile. He holds a PhD in machine learning, written at Inria under Cordelia Schmid on vision-language models. In 2017 he renovated a house with his own hands, inside and outside insulation, new windows, a heat pump and solar thermal, and took one conviction from it: the plan is the easy part, the site is where everything can go wrong. He now designs the software that lets renovation companies produce reliable energy studies, from the 3CL survey through to heat pump sizing. On the blog he writes about what he implements: the 3CL-DPE 2021 method, NF EN 12831 and building physics as a calculation engine has to handle them, assumption by assumption.

Between a single hydraulic network and room-by-room equipment, your clients mainly want comfort without a runaway bill. In renovation, the right choice turns on three very concrete points: the state of the building, actual usage patterns, and the ability to control zone by zone. By framing these criteria as early as the visit, you secure the quote and avoid bad surprises on site.

On a job site, the right heating choice often comes down to two simple questions. What level of comfort does your client expect, and what network already exists in the home, radiators, underfloor heating, or nothing at all. By asking the right questions from the site visit, you avoid bad surprises and protect your margin.

On an energy renovation job site, you're no longer just 'the person who runs the cables.' Heat pumps, mechanical ventilation, heat-pump water heaters, load control — it all comes down to your connections and settings too. When your clients want grants, what they really expect is a rigorous professional, able to coordinate, explain, and deliver an installation that runs right the first time. And that's exactly where your trade gains value.
