What Buchler and Partner does

Büchler & Partner AG is a privately held Swiss electrical engineering consultancy (Elektroingenieurbüro) headquartered in Uster, canton of Zürich, providing comprehensive electrical planning services for commercial, industrial, residential, educational, and aquatic facility building projects. The firm operates with 15 qualified employees under owner-management by Martin Gassler (CEO) and Roland Dietz, who assumed control from founder Carlo Büchler in 2011. The company has been continuously operating since 1990 and serves the Zürich regional market exclusively, with no geographic expansion beyond a single office location.

The firm delivers a portfolio of 21 distinct service modules spanning the full electrical installation lifecycle, including core Elektro-Engineering, VKF-compliant fire protection planning (Brandschutzplanung, Brandmeldeplanung), lightning protection, lighting design, photovoltaic and battery storage engineering, e-mobility load management, building automation, smart-home, fiber optics, and security systems. Project execution is supported by expert opinions (Expertisen/Gutachten), specialized construction management (Fachbauleitungen), cost management, and maintenance concepts. Technology is built on industry-standard CAD/CAE tools (TinLine, ECS-CAD, Nova-Plan, EXS CAD) and BIM methodologies rather than proprietary platforms or AI-driven systems.

Revenue is generated through project-based professional services fees for electrical planning, design, and project management on new construction and renovation projects. The go-to-market model is direct enterprise engagement with building owners, developers, architects, and general contractors in the Zürich canton, with project acquisition driven by referrals and existing client relationships rather than marketing programs. Pricing is determined per engagement and not publicly disclosed. No funding rounds, institutional investors, or external capital have been raised; ownership remains concentrated among the two managing directors and a supervisory board member.

Broad incumbents

• ABB Ltd: Swiss-headquartered global electrification and automation major. Relevant as a broad incumbent in electrical infrastructure and as a domestic supplier whose products and standards influence Swiss electrical-engineering practice.
• AFRY AB: Large European engineering and design firm (formerly ÅF) with significant operations in Switzerland. Competes for the same institutional and industrial electrical-planning mandates but as part of a much broader, multi-discipline portfolio.
• Schneider Electric SE: Global leader in building automation, energy management, and electrical distribution. Competes indirectly through productized BMS/BAS and EPMS offerings, shaping the standards that Büchler & Partner AG designs around.
• Siemens Smart Infrastructure: Global building technologies and electrical-systems giant. Relevant as a broad incumbent in building automation and electrical infrastructure, and as an OEM whose products are integrated into Swiss building projects.

Direct peers

• HHM Gruppe (Hefti. Hess. Martignoni): Swiss engineering group specializing in electrical engineering, building automation, and energy for buildings. Closely comparable service portfolio, target clients, and Swiss regional model.
• Fanzun AG: Swiss architecture and engineering firm offering building services planning including electrical engineering. Comparable service model for residential, commercial, and industrial building projects in the Alpine region.
• ewp AG: Swiss engineering firm providing planning services across energy, building services, and infrastructure. Direct competitor for electrical and building-automation planning mandates in Switzerland.
• Basler & Hofmann AG: Swiss engineering consultancy covering electrical planning, building services, fire protection, and infrastructure. Directly comparable services and end markets, with national footprint and broader disciplines.
• Amstein + Walthert AG: Leading Swiss engineering consultancy with deep MEP, building automation, and energy-services practices. Direct peer in electrical planning for buildings, but at significantly larger scale (several hundred employees) and broader geography.
• Emch+Berger AG: Swiss engineering consultancy with building-services and infrastructure practices. Overlaps with Büchler & Partner AG on electrical and building-systems planning for institutional and commercial clients.
