What kapa does

kapa (legal name: Kalberer + Partner AG) is a privately held Swiss engineering consultancy operating as a neutral planning office for building services engineering (Haustechnik). Founded around 1982 and headquartered in Bad Ragaz with a secondary office in Chur (canton Graubünden), the firm plans complete heating, ventilation, air conditioning/refrigeration, and plumbing installations for projects ranging from single-family homes to five-star hotels. Over 1,000 projects have been completed across residential, commercial, industrial, hospitality, healthcare, educational, and public-sector clients in Eastern Switzerland.

The firm's core technical differentiator is energy-cycle optimization: integrating renewable energy sources such as geothermal heat pumps, solar thermal systems, wood chip heating, heat recovery, and thermal building activation systems (TABS) into overall building concepts that minimize primary energy demand. Service lines include Building Technology Planning, Overall Concepts (Gesamtkonzepte), Coordination (spatial and technical installation planning), Renewable Energy Solutions, Special Solutions for complex problems, and Industrial Planning (complete media planning for production facilities, including compressed air, dew point water, and cooling water systems). The technology stack is conventional engineering practice delivered by a specialized human workforce; no AI/ML capabilities are disclosed.

Revenue is generated through fee-based professional services with project-specific quotations tied to scope and complexity. Go-to-market is enterprise field sales via direct engagement with property owners, municipalities, institutions, and businesses, supplemented by relationships with architectural firms. Marketing is minimal; the firm is owner-operated under Geschäftsführer Andreas Kalberer, with a workforce of 51-100 and a 30-year continuous apprenticeship program functioning as a key talent pipeline. No external funding, M&A activity, or public listing is disclosed.

Broad incumbents

• Equans Switzerland: Multinational multi-technical services firm covering HVAC, energy, and building-services engineering in Switzerland. Comparable in target deliverables but with broader portfolio and significantly larger resource base.
• ENGIE Solutions (Switzerland): Multinational energy and multi-technical services provider with significant Swiss operations in HVAC, building services, and energy efficiency. Overlaps with kapa on heating/cooling/renewables planning but operates at much larger scale as a generalist.
• Siemens Smart Infrastructure (Switzerland): Large international provider of building automation, HVAC systems, and energy-management solutions with a Swiss presence. Overlaps with kapa on building-services planning for complex facilities but is vendor-aligned and operates globally.

Direct peers

• Amstein + Walthert AG: Switzerland's largest independent building-services engineering firm, offering planning of heating, ventilation, climate, refrigeration, and sanitary systems for residential, commercial, and industrial projects. Directly comparable to kapa in core offering, but operating at national scale with multiple offices.
• Eicher+Pauli AG: Swiss engineering consultancy specializing in building services (HVAC, heating, cooling, sanitary) and energy optimization, with a similar focus on energy efficiency and renewable integration. Closely comparable in service mix and target segments.
• Holinger AG: Swiss engineering group active in building services, energy, and water/infrastructure, with a strong focus on renewable energy and energy-cycle optimization — directly aligned with kapa's renewable-integration and Gesamtkonzepte value proposition.
• R+B engineering AG: Zürich-based engineering firm providing building services and energy planning for complex residential, commercial, and industrial projects. Comparable in technical scope (heating/ventilation/climate/sanitary planning) and customer profile.
