Geoenergy HVAC Operation Lead


Who we are:

Celsius Energy is the story of three engineers, brought together by their commitment to the environment, who chose to use their expertise to the meet the challenge of our times; fighting climate change.  The observation?  Heating and cooling of buildings comprises 25% of CO2 emissions worldwide, however 70% of the energy necessary to meet these needs is right under our feet, in a continuous and endless manner. 

Our mission is climate: connect buildings to the earth to (re)connect the company to climate challenges, making low-carbon buildings on a large scale.  Our solution is a highly optimized ground-source heat pump system for both new buildings and renovations with applicability even in dense urban areas with:

  1. A scientifically dimensioned geothermal borehole arrangement as driven by thermal capacity of drilled test well(s) and building energy consumption to ensure geothermal resource right-sizing
  2. A pyramid-shaped geothermal energy exchanger equipped with closed double-U loops to minimize surface footprint and maximize thermal exploitation of the underground
  3. A digital control to minimize electricity consumption and maximize geothermal resource performance and longevity in real time

Today, Celsius Energy is an expert, committed multidisciplinary team connected to its ecosystem: companies, private and public participants, engineers, researchers and partners. We are working for the general public by developing our solution and continually improving its performance.  We want to accelerate the movement of a massive and indispensable energy transition for our society. We bring teams together around our expertise and connect all trades necessary to deploy a turnkey solution in line with our values and ambitions.

Celsius Energy has been recognized as one of the 50 most promising solutions for the future of climate worldwide and is a recipient of the Solar Impulse Efficient Solution label.

Celsius Energy is a scale up company of Schlumberger New Energy – the worldwide leader in subsurface drilling, characterization, and digital solutions. Celsius has over a 100’s employee’s in France, the US, UK, and delivers solutions for external clients.
