What Weinmann-Energies does
Weinmann Energies is an independent Swiss consulting engineering firm founded in 1980 by Charles Weinmann in Echallens, Vaud, and now operating across three offices in Western Switzerland (Vaud, Geneva, Neuchâtel). The firm provides technical building engineering services across five interdependent domains: CVCS-MCR engineering (heating, ventilation, air conditioning, plumbing, fire protection, and regulation); energy and sustainability consulting including Minergie, SméO, and SNBS certification work; building physics and expertise (thermal calculations, CFD simulations for smoke extraction and urban heat island effects, solar protection optimization); energy optimization and audits for existing buildings; and BIM/digitalization services for multi-discipline information modeling. It serves building owners, architects, public institutions, healthcare facilities, and industrial enterprises through project-based consulting engagements, with notable references including Hôpital Riviera-Chablais, Japan Tobacco International Geneva, EPIC Pulse Cheseaux-sur-Lausanne, Gymnase de Renens, Jaeger-Lecoultre, Swiss Federal Railways (CFF), and the Swiss Embassy in Algeria.
The firm employs more than 100 highly qualified collaborators, including EPFL and HES engineers, ES technicians, CFC designers, BIM specialists, and federally certified Master experts, with several staff holding leadership positions in industry bodies such as SIA Vaud. Its go-to-market is enterprise field sales via direct client engagement, professional referrals, and public tenders, with no intermediary distribution channels. The technology stack centers on BIM/REVIT-based design, building physics simulation, CFD modeling, and energy/sustainability calculation tools, complemented by internally developed process and quality-control tools. Pricing is project-based and individually negotiated; revenue is generated entirely through professional service fees tied to the planning, renovation, and optimization of technical building installations. In January 2026, a generational leadership transition placed Luc Giger, Egilio Berlendis, Alessandro Callea, Cédric Haldimann, and Julien Regamey as associate directors, while founders' successors Zurita, Clerc, and Krieg remain active in the firm.
