What Ingenieurburo Liebert Versorgungstechnik Gmbh & Co. Kg does

Ingenieurbüro Liebert Versorgungstechnik GmbH & Co. KG is a privately held German engineering consultancy founded in 1994 and headquartered in Hüfingen, with additional offices in Berlin, Frankfurt am Main, and Hamburg. The firm specializes in technical building equipment planning (Technische Gebäudeausrüstung / Versorgungstechnik) — covering heating, cooling, ventilation, sanitary, electrical, and building automation systems — with a particular focus on sustainable, climate-neutral, CO2-neutral, and energy-positive building design. Its technical approach incorporates Building Information Modeling (BIM), geothermal energy systems, adiabatic cooling, and Cradle-to-Cradle design principles, and has produced projects certified to DGNB Platinum and LEED Platinum standards. Service delivery spans all HOAI fee structure phases (1-9) covering planning, project steering, consulting, green building certification support, and trade-specific engineering.

Liebert serves enterprise clients across healthcare (Universitätsklinikum Göttingen, Charité Berlin, Uniklinikum Würzburg, Schott AG), banking (Sparkasse Schwarzwald-Baar, Volksbank Villingen-Schwenningen), automotive (Mercedes-Benz, Daimler, IMS Gear, Mahle, Jaguar), and real estate development (Becken Development, Patrizia, MOMENI, Covivio), as well as industrial and institutional customers such as Messe Stuttgart and Würth. Revenue is generated through project-based professional services engagements priced under the HOAI fee structure, typically structured as multi-year contracts tied to specific building projects. The firm is led by three Managing Directors — Thomas Liebert (Chairman and founder), Patrick Merkt, and Stefan Ballmer (co-shareholder since 2021) — all holding Dipl.-Ing. (FH) engineering degrees. In 2024, Liebert announced its merger into the NEXOPLAN-Gruppe to secure long-term scale and continuity while preserving its operational identity and four German locations.
