About us

Geothermal systems are among the most effective ways to cut energy use, peak electrical demand and greenhouse-gas emissions, yet they are still a niche in HVAC engineering. During my years as a consultant, I often saw a GSHP option dropped early in a project because it looked complicated, or a field oversized for lack of experience, which raised its cost and made it harder to defend. I wrote the Analysis Suite to deal with both problems.

The methods for designing a ground-source heat pump system well have been published for years, but most of them live in research codes that few practising engineers can run. I wanted one application that puts them in the hands of engineers, consultants and students, and that works as well on a single house as on a large institutional or commercial project. A project can start from a thermal response test or from design values you already have. In both cases, the suite then takes it through three steps: characterizing the ground, sizing a borehole field of any shape, and balancing the distribution network so that each borehole gets the flow it was designed for.

I started writing the software in 2021, drawing on my past consulting experience in the geothermal industry and on my work as a professor at Polytechnique Montréal. The methods come from research; the way the interface is organised comes from the systems I designed as a consultant, under real project deadlines. Students, engineers and consultants now use it in eleven countries.

The suite pairs an intuitive, fast-to-learn design environment with a high-performance simulation engine built on decades of peer-reviewed research. I wanted designers to spend their time on borehole sizing, on fluid temperatures, on seasonal efficiency, on the physics that actually governs performance, rather than on software mechanics. When rigorous methods are made approachable, a field can be sized on what the ground actually does, instead of on a margin taken for safety.

The Analysis Suite is developed and distributed by P³ Geothermal, a spin-off of Polytechnique Montréal. Many of its core models come from the work of my graduate students, and whenever possible a share of the software's revenue goes back to the students whose research made it possible, because academic contributions deserve recognition beyond a publication.
