Energestion SA

What Energestion SA does

Energestion SA is a Geneva-based SIA engineering consultancy founded in 1981 that specializes in CVCRS — Chauffage, Ventilation, Climatisation, Régulation and Sanitaire — technical design for the building and industrial sectors. The firm delivers an integrated engineering portfolio: energy audits and certifications (CECB+, Minergie, HPE/THPE), heating and cooling production design (heat pumps, geothermal, biomass, cogeneration, district heating), controlled ventilation, building automation, sanitary and medical-gas plumbing, BIM Management under openBIM/IFC standards, and district heating/cooling network design (Réseaux de quartier). Energestion supports clients across the full project lifecycle — initial analysis, feasibility studies, permits, tendering, construction management, commissioning and follow-up.

The firm serves building owners, developers, contractors, and institutional clients in the Geneva region and broader Western Switzerland. Visible reference customers span hospitality (Marriott Hotel Meyrin, 263 rooms), healthcare (HUG Maternité and 3A-Loëx hospital renovations, EMS Vuadens 123-bed nursing home, IEPA Meyrin 32 apartments), residential (186-unit HBM Emile Dupont Ouches Sports, 94-unit Tour Saint-Marc Petit-Lancy), education (Groupe Scolaire Belle-Terre for 2030 completion), and district-energy infrastructure for the region.

The business model is professional-services engineering fees billed on a project-by-project basis; pricing is not publicly disclosed and quotations are scope-driven. Go-to-market is direct enterprise engagement with no intermediary channel, supported by a LinkedIn corporate page, Google Maps local visibility, and a website portfolio as the primary marketing surface. The firm has approximately 20-22 employees, is owned and administered by co-founders Martial Götz and Raphaël Muriau (with Oriane De Facci as associate), has no subsidiaries, no institutional investors, and no disclosed M&A or capital-raising activity. Operationally, Energestion is investing in credentialing depth (QM Chauffage au bois, Suissetec sanitary diplomas, buildingSMART, hydraulic balancing) and recent team expansion in sanitary and CVCRS project management.

Specializes in sustainable building design, energy efficiency, and MEP engineering - directly overlapping with Energestion's Minergie and eco21 expertise at international scale.
• Arup: Global engineering, design, and consulting firm with building services practice and renowned sustainable design capability. Tangentially overlaps with Energestion's energy efficiency and HVAC focus, typically engaging on larger-scale or more complex projects.
• WSP Global: Global engineering consultancy with significant Swiss operations providing MEP/building services design, energy consulting, and sustainability advisory. Larger scale and broader portfolio position WSP as a typical incumbent competitor for major Swiss commercial and infrastructure projects.
• Buro Happold: International engineering consultancy specializing in building services, sustainability, and MEP design with strong BIM/digital delivery capabilities. Notably comparable to Energestion's BIM and buildingSMART practice but operating at much larger scale with global project footprint.
• AFRY (formerly ÅF Pöyry): International engineering and design consultancy with Swiss offices following the Pöyry heritage. Operates a building services practice that competes with Energestion for large-scale commercial, healthcare, and industrial MEP projects, typically at much larger scale.
• Stantec: International engineering, architecture, and environmental services firm with Swiss offices. Building services practice competes for hospitality, healthcare, and institutional MEP projects similar to Energestion's Marriott and HUG portfolio.
• Sweco: European engineering consultancy with Swiss operations (Sweco Schweiz). Provides MEP and building services design across multiple sectors with broader geographic reach, positioning it as a typical incumbent competitor for cross-region European projects.
