K. Wintsch & Cie SA

What K. Wintsch & Cie SA does

K. Wintsch & Cie SA is a Geneva-based engineering consultancy founded in 1962 by Kurt Wintsch and operating as a Swiss Société Anonyme since 1990, with its headquarters at Chemin de la Distillerie 4 in Bernex (Geneva). The firm specializes in CVCR engineering — Chauffage, Ventilation, Climatisation, Réfrigération (heating, ventilation, air conditioning, and refrigeration) — for sustainable construction and building technical installations, and has completed over 750 projects across administrative, residential, healthcare, laboratory, and hospitality building types.

The service portfolio covers the full building lifecycle and is delivered through eight core product lines: HVACR engineering services, building energy concepts, dynamic CFD simulation and thermal-comfort analysis, BIM modeling with multidisciplinary coordination, MCR (Measurement-Control-Regulation) building automation, technical audits and CECB/CECB+ certification, building-permit application support, and project planning and management. The technical stack is built on advanced engineering software rather than proprietary AI — CFD simulations, dynamic building-energy simulation, full BIM coordination with conflict detection, and PLC-based MCR automation form the core differentiation, enabling the firm to address complex thermal-comfort, pollutant-control, and fire-safety scenarios.

The business model is project-based professional services sold via direct B2B engagement in the Geneva metropolitan area. Pricing is custom-scoped per engagement, with individual project labor costs ranging from CHF 10,000 to CHF 50 million and contracts typically spanning multiple years. Go-to-market relies on referrals from architects, property developers, and construction firms, supplemented by active participation in professional bodies (SIA, SSES, Die Planer-SICC, REG) and a strategic alliance with SIG for district heating and the éco21 energy-efficiency award program. Client segments are primarily administrative and commercial buildings, followed by residential developments seeking Minergie certification, with specialized mandates in healthcare, laboratory, and hospitality. The firm is led by Florian Goubet, who took over management in 2022.

Expansion highlights3 records

Direct peers

• EBP (Ernst Basler + Partner): Swiss engineering and consulting firm with established building energy and HVAC capabilities, including energy audits and dynamic simulation. Comparable in offering building energy consulting, CECB-style audits, and sustainable construction advisory, though operating at a larger scale.
• Basler & Hofmann: Swiss engineering consultancy with strong practices in sustainable building design, HVAC, and energy concepts. Comparable in services offered (energy concepts, building technical installations) and in working with Minergie/standard-compliant projects, though headquartered in the Zurich region.
• Amstein + Walthert: One of the largest Swiss engineering consultancies with deep HVAC/building energy expertise across multiple cantons. Directly comparable to K. Wintsch in core CVCR/building energy services, but with a much broader service portfolio and headcount, making it the most relevant scale peer in Switzerland.
• Waldhauser + Hermann AG: Swiss engineering consultancy specializing in building services (Heizung, Lüftung, Klima) and energy concepts, directly comparable to K. Wintsch's CVCR focus. Operates in the German-speaking part of Switzerland, serving as a geographic parallel peer.
• Hunziker Partner AG: Swiss engineering firm offering HVAC, building automation (MCR/GMS), and energy consulting services. Closely comparable in the MCR/building automation and CVCR engineering stack that K. Wintsch highlights as a differentiator.

Regional players

• Stucky AG: Swiss engineering consultancy with energy and building technical expertise, with a Western Switzerland presence relevant to the Geneva market. Comparable in offering building energy consulting and CVCR engineering but with a different geographic footprint.

Others

• HRS Real Estate AG: Swiss total contractor for large construction projects that frequently engages HVAC engineering consultancies like K. Wintsch as subcontractors. Relevant as a downstream client/ecosystem participant rather than a direct competitor.

Emerging players

• Sinteco AG: Swiss engineering consultancy with focus on building energy, sustainability, and HVAC/MCR services. Comparable as a niche Swiss peer operating in similar sustainable-building and energy-efficiency consulting markets, though at a smaller scale.

Broad incumbents

• Gruner AG: Swiss engineering firm with HVAC and building services capabilities alongside broader civil/structural offerings. Comparable on building technical installations but operates as a broad incumbent across multiple engineering disciplines.
• Burkhalter Group: Swiss electrical and building services group with significant HVAC-adjacent capabilities. While primarily electrical, it intersects with building technical installations in Switzerland and serves as a broad incumbent in the same end-market.
