Andy Wickart Haustechnik AG

What Andy Wickart Haustechnik AG does

Andy Wickart Haustechnik AG (AWIAG) is a family-owned Swiss engineering consultancy headquartered in Cham, Canton Zug, that plans and designs building technology (HLKS — heating, ventilation, air conditioning, sanitation), building automation (MSRL), and district-scale thermal energy systems. The firm was founded in 1988 and operates from four branches (Cham, Kemptthal, Zürich, and a forthcoming office in Pfäffikon SZ in autumn 2026), with a separate drone-services sub-brand (AWIAG Luftaufnahmen) based in Goldau. The company serves municipalities, energy utilities, property developers, industrial clients, and architectural firms, with particular depth in non-conventional waste heat recovery (wastewater treatment plants, crematoriums, industrial processes), multi-source district energy networks, and BIM-based integrated project delivery. Notable projects include the CHF 28 million Papieri-Areal multi-energy grid in Cham, the Menzingen wood-chip heating network (CHF 10.6 million), the V-ZUG Technology Cluster (CHF 4.4 million), and Switzerland's first absorption heat pump installation in the Lenzerheide district heating network.

AWIAG generates revenue as a professional services firm, billing engineering and planning fees tied to SIA service phases and the construction value of each project. Customer acquisition is sales-led, driven by direct referrals, architectural partnerships, and tender wins with public-sector and utility clients. The service portfolio spans HLKS planning, thermal networks and energy centres, building automation and energy monitoring, BIM/Open-BIM coordination, solar/PV and battery storage design, energy certification (MINERGIE, GEAK), simulations, specialist construction management, fire protection consulting, utility infrastructure planning, and independent QS/expert mandates. The drone sub-brand adds a parallel commercial line for inspection, thermography, and surveying services. The firm runs an internal apprenticeship programme for building technology planners, indicating a deliberate build-out of engineering capacity. Key representative is Thomas Wickart; the company is privately held with no external investors or parent entity disclosed.

Product overview

Andy Wickart Haustechnik AG (AWIAG) is a family-owned engineering consultancy for energy and building technology based in Switzerland. The company operates as a single unified service practice rather than a platform-plus-modules architecture. Their portfolio includes HLKS planning (heating, ventilation, air conditioning, sanitation), thermal networks and energy centers, MSRL/building automation, BIM/digital construction, building physics and energy consulting, solar energy/photovoltaic systems, energy certification (MINERGIE, GEAK), operational optimization and energy monitoring, simulations, specialist construction management, fire protection concepts, utility infrastructure planning, and expert/quality assurance services. A distinct sub-brand, AWIAG Luftaufnahmen, provides professional drone services including inspection flights and thermography. The company also runs an apprenticeship program for training building technology planners. Projects span residential, commercial, industrial, healthcare, and public buildings, with notable expertise in district heating networks, energyverbund systems, and sustainable building technology.
