Lier Energietechnik

What Lier Energietechnik does

Lier Energietechnik is a Swiss engineering, planning and consulting firm specializing in industrial heat, cooling and process technology, with operations dating back to 1925. The company provides technical services in thermal networks, energy centers, process and plant engineering, energy consulting, measurement/control/regulation (MSRL) and building automation, operational optimization, energy monitoring, simulations, GEAK certification, solar/photovoltaic planning, BIM/digital construction, and expert assessments. Its primary client base is industrial facilities requiring heating, cooling and process-temperature solutions in Switzerland, delivered through direct professional-services engagements with enterprise customers.

As of February 1, 2026, Lier Energietechnik was acquired by AWIAG (Andy Wickart Haustechnik AG), a Swiss building services engineering firm based in Cham. Under the transaction, AWIAG assumed legal succession, retained the entire Lier team, and formed the new specialist department for steam and hot water (Dampf- und Heisswasser) within AWIAG. The former Lier headquarters in Wallisellen was supplemented by a new AWIAG competence location at Kemptpark 30, Kemptthal, alongside existing AWIAG branch offices in Cham (HQ), Zurich and a planned Pfäffikon SZ branch opening in Fall 2026. The combination expands the merged entity's industrial-process capability while preserving Lier's neutral engineering brand and team continuity under AWIAG.
