What Waldhauser + Hermann does

Waldhauser + Hermann AG is an independent Swiss engineering firm founded in 1973 and headquartered in Münchenstein (Basel-Landschaft), specializing in building services engineering (HLKK — heating, ventilation, air conditioning, refrigeration), energy consulting, sustainability assessment, and building automation. The firm serves architects, building owners, public sector clients, and general contractors across Switzerland, primarily in the Northwestern region and Basel area, with selective cross-border engagements (notably Hamburg). Its service portfolio spans Haustechnikplanung+ (classical HLKK engineering), Fachplanung Wärme- und Kältezentralen+ (heating and cooling plant specialist planning), Energie- und Nachhaltigkeitsberatung+ (SIA 2040 / 2000-Watt Society assessments, building physics, energy simulation via IDA ICE), Energetische Betriebsoptimierung+ (operational energy optimization), and the BIM 2 FM+ methodology that transfers planning data into facility management as a digital twin.

The firm has operated since 2014 on a BIM-based methodology, using Revit for HLKK modeling, Granlund Designer as a cloud-based component database, IDA ICE and SolarComputer for simulation, and Revizto/Navisworks/BIMcollab for multi-trade coordination. The BIM 2 FM workflow creates digital twins of physical buildings that can be transferred into Granlund Manager FM software for ongoing operations, with the property owner retaining data ownership. Projects are won primarily through architectural competitions, with the firm partnering with leading Swiss practices (Boltshauser Architekten, Christ & Gantenbein, jessenvollenweider, mlzd, Burckhardt) on over 60 first-place wins spanning cultural institutions (Fondation Beyeler, Kunstmuseum Basel), healthcare (PUK Zürich, Botnar Research Centre), education, and infrastructure (SBB Westbahnhof, Buszentrum RBS).

The business model is project-based professional services with fees negotiated per engagement; revenue derives from HLKK design, energy concepts, BIM coordination, building automation design, and operational optimization. The firm employs approximately 50 staff across HLKK engineering, building automation, energy consulting, and administration. Ownership is held equally by seven active co-owners (Christoph Borer, Gabriel Borer, Pascal Emhardt, Roman Hermann, Lars Köppke, Marco Waldhauser, Stefan Waldhauser), with the management board comprising Marco Waldhauser (CEO), Roman Hermann, and Stefan Waldhauser. The firm holds memberships in SIA, suissetec, suisse-ing, Minergie, Swissolar, ASHRAE, and buildingSMART Switzerland, with co-owners in leadership roles across SIA standards committees, the BIM Round Table Gebäudetechnik, Forum Energie Zürich, and IG Holzenergie Nordwestschweiz.
