ACCON GmbH

What ACCON GmbH does

ACCON GmbH is a Germany-based environmental and engineering consultancy founded in 1975, headquartered in Greifenberg, Bavaria. The firm specializes in noise and vibration control, air pollution control and dispersion modeling, thermal building physics, light pollution assessment, and approval/permitting management for industrial, infrastructure, and construction projects. Its core technology stack combines physical measurement instrumentation (multi-channel vibration systems, an in-house reverberation chamber) with established regulatory dispersion models (AUSTAL2000, MISKAM, LASAT) and proprietary tooling such as the Betriebliches Lärm-Informations-System (BLIS) for operational noise modeling. The company is a DAkkS-accredited testing laboratory under DIN EN ISO/IEC 17025:2018 and an officially notified body under § 29b of the German Federal Immission Control Act (BImSchG), giving it legally recognized standing for immission assessments.

The company generates revenue through project-based professional services engagements rather than productized software, with pricing determined per project scope and contract length. Customers span the European Commission, German federal and provincial ministries, municipalities, airport operators, road and rail authorities, industrial and commercial facility operators, and architects/planners; named industrial references include SGL Carbon and Güntner. Since joining the iC Group in October 2019, ACCON has operated as a subsidiary within a broader engineering conglomerate, retaining its brand and German managing directors (Markus Petz, Thea Hirle, Wolfgang Unterberger) while leveraging the parent's international project pipeline.

Geographically, ACCON operates eleven office locations: seven across Germany (Greifenberg HQ, Augsburg, Nördlingen, Köln via ACCON Köln GmbH, Saarland, Rheinland-Pfalz, Friedrichshafen, plus Saxony/Radeberg), two in the UK under ACCON UK Ltd., and subsidiaries in Italy (ACCON Italia S.r.l.) and Romania (ACCON Environmental Consultants Srl). The firm participates in national standardization and European collaborative research projects, contributing to the state of the art in environmental and occupational protection. Marketing is conducted almost entirely through direct professional referrals, the corporate website, and research participation rather than paid channels.

Core offering

ACCON GmbH is a German engineering consultancy providing measurement, calculation, expert assessment, and consulting services focused on sound and vibration technology, air pollution control, light nuisance, thermal building physics, and approval/permitting management. The firm serves public and private clients across Europe, delivering services such as environmental impact assessments, immission control licensing support, dispersion modeling, building and room acoustics, vibration analysis of machinery, and operational noise information systems.

Product overview

ACCON GmbH is an environmental and engineering consultancy offering a comprehensive suite of specialized consulting services rather than a unified software product. The core portfolio centers on environmental noise and vibration control (industrial, traffic, aircraft, sports facilities, building and room acoustics) and air pollution control (dispersion modeling, emissions from traffic, industry, and agriculture). Additional services include thermal building physics, light pollution assessment, approval/permitting management, and energy efficiency consulting. The company operates as an interdisciplinary team of engineers, physicists, geophysicists, and geographers providing measurement, calculation, expert assessment, and consulting services for private and public clients since 1975. Services are delivered through multiple German offices and international subsidiaries in UK, Italy, and Romania.
