Description

Margaux Peltier is the co-founder and CEO of Enerdrape, a Swiss startup turning underground infrastructure into renewable energy sources. From parking garages to metro tunnels, Enerdrape’s modular geothermal panels harness untapped subterranean heat to provide sustainable heating and cooling for buildings without disruptive drilling or invasive construction.


Margaux’s background in HVAC design and engineering was followed by a Masters in Civil Engineering in Lausanne where her thesis formed the basis of Enerdrape’s technology. Since then, she has led Enerdrape through award-winning pilot projects in Switzerland and ambitious expansions into the US, including Chicago’s largest underground parking complex.
