Samuel Letellier-Duchesne

I work at the intersection of building science, data, and climate action.

By day, I’m part of the Design Analytics team at Introba, helping solve complex decarbonization challenges for large building portfolios—things like electrification, HVAC retrofits, and energy modeling.
I’m also the Co-Founder of Carbon Signal®, a platform we built to help real estate teams figure out what actually matters when trying to cut carbon across hundreds of assets. We use a mix of simulation, analytics, and smart machine learning to turn messy decisions into clear next steps.

My background’s in mechanical engineering—I did a PhD at Polytechnique Montréal and a postdoc at MIT—but I’ve always been more interested in applying research than publishing it. These days, I’m focused on building tools and teams that can make decarbonization faster, smarter, and scalable
