What Aicher, De Martin, Zweng does

Aicher, De Martin, Zweng AG (ADZ) is a privately held Swiss engineering firm founded in 1976, headquartered in Luzern with additional offices in Zürich and Basel. The company provides specialist planning services for building technology systems, covering heating, ventilation, cooling, sanitation, building automation, energy and sustainability consulting, laboratory planning, and project coordination. Its service portfolio is organized around integral planning across all SIA phases, positioning ADZ as a coordinator of HVAC, sanitary, and automation disciplines rather than a single-trade consultant. The firm holds certified GEAK energy advisor status and supports Minergie, LEED, and SNBS sustainability certifications.

ADZ operates as a subsidiary of BKW Engineering AG, itself part of the broader BKW Gruppe (BKW Group), a Swiss energy and infrastructure services platform. The business model is professional services: project-based engineering consulting delivered on a quote-by-project basis to building owners, property developers, architects, general contractors, and research/industrial facility operators. The company markets through a modest digital presence (LinkedIn, XING, Instagram, YouTube, Google Ads/Analytics) and relies on direct enterprise field sales for new engagements. Revenue, headcount, and contract values are not publicly disclosed; the firm is not listed and has no known funding rounds or M&A history.

Technologically, ADZ has built BIM (Building Information Modeling) capability with over 10 years of experience, applying it to planning, coordination, and management of complex building services. Building automation is delivered at the field, automation, and operations/management levels with neutral product evaluation. The firm is Switzerland-only in geographic scope, with no disclosed international operations.
