Siganet

What Siganet does

Siganet GmbH is a German engineering consultancy founded in November 1999 as a wholly-owned subsidiary of agn-Gruppe, specializing in three core technical building equipment (TGA) disciplines: building automation (KG 480), security technology (KG 450), and electrical power networks (KG 440). The company's central technical proposition is Integrationsplanung (cross-trade integration planning), a manufacturer-neutral methodology that coordinates these three disciplines using open interoperability standards (BACnet/IP, OPC UA) and BIM methods (openBIM and closedBIM). Proprietary frameworks include the OT network Zonenkonzept based on IEC 62443 and BSI-Grundschutz, a systematic condition assessment methodology (ZAGA) developed for BImA and incorporated into the AMEV guideline in 2023, and the recently introduced BACtwin AI-based building automation concept. Supporting service modules include commissioning management, technical monitoring, target/requirements planning, and digital twin capabilities.

Siganet operates exclusively as a B2B engineering consultancy through four German offices: Ibbenbüren (HQ), Berlin, Frankfurt am Main, and Münster. Revenue is generated via professional services engagements sourced through formal public procurement processes (VgV, VOF, Vergabeverfahren) for federal and state public construction clients, and direct commissions for private clients. The primary customer segments are federal and state public construction (BImA, BBR, BLB NRW, GMSH), universities and research institutions (Max Planck, Leibniz, University of Stuttgart, Leipzig), justice and correctional facilities, and industrial/critical infrastructure operators (WILO, CHEMPARK/Currenta). With over 70% of revenue from third-party clients outside the agn-Gruppe by 2017, Siganet has demonstrated commercial independence from its parent.

The company reached over 4 million EUR in annual revenue by 2023 (up from over 1M EUR in 2010), employs 30+ staff, and is led by Managing Director Holger Wallmeier, who has held the role since shortly after founding. Notable credentialed projects include the Bundesministerium für Umwelt extension building (BNB Gold target), UN-Campus Bonn Climate Tower (BNB Gold achieved), World Conference Center Bonn (~4,000 data points), and the Tier III data center in Göttingen.

Core offering

Siganet is an engineering consultancy providing planning services for three core technical building disciplines: building automation (KG 480), security technology (KG 450), and electrical power networks (KG 440). The company's distinctive offering is cross-trade Integrationsplanung — coordinating building automation, security technology, and electrical networks into manufacturer-neutral, unified systems. It serves public sector clients (federal and state government buildings, universities, research institutions) and select private-sector clients (industrial operators, banks) primarily through public procurement processes and direct commissions across Germany.

Product overview

Siganet is an engineering and consulting firm specializing in technical building equipment (TGA) with three core service areas: building automation (KG 480), security technology (KG 450), and power networks (KG 440). The company operates as a subsidiary of the agn Group, offering cross-trade integration planning that coordinates these three disciplines. Supporting services include condition assessment (Zustandsbewertung), commissioning management (Inbetriebnahmemanagement), technical monitoring, target and requirements planning, BIM methodology, and digital twin capabilities. The portfolio is organized as a unified engineering services offering with modular add-ons rather than discrete software products. The company serves public and private clients across Germany with projects ranging from government buildings and universities to industrial facilities and critical infrastructure.

Partnerships

Three partnerships are on record, tiered core and flagship.

• VDMA AG BIM Gebäudeautomation und ElektrotechnikcoreStrategic or Co-development Partner · 8 September 2022siganet joined the VDMA Working Group for BIM in Building Automation and Electrical Engineering (AG BIM GA/ET) upon its founding in September 2022. The working group, comprising 18 companies and 5 universities, advocates for greater consideration of TGA disciplines in BIM planning processes and develops technical standards.
• agn-Gruppe (Agn Niederberghaus & Partner)coreStrategic or Co-development Partnersiganet GmbH was founded in November 1999 as a subsidiary of agn-Gruppe. The two companies maintain close operational ties: shared office spaces at multiple locations (Münster, Ibbenbüren), joint general planning projects, and agn serves as a referral channel for siganet's specialized engineering services. siganet operates with management autonomy while benefiting from the agn ecosystem.
• Bundesanstalt für Immobilienaufgaben (BImA)flagshipStrategic or Co-development PartnerBImA commissioned siganet to develop a standardized methodology for assessing building automation systems across top federal authorities. The resulting ZAGA (systematic condition assessment) process was incorporated into the AMEV Building Automation guideline in 2023. siganet also developed evaluation sheets for cybersecurity assessment of GA systems.

Broad incumbents

• Drees & Sommer: Leading German engineering consultancy with broad TGA, building automation, energy, and sustainability planning practices. Overlaps with siganet on public-sector and complex building projects but operates at much greater scale with international footprint, making it a broad incumbent rather than a direct specialist peer.
• Schneider Electric: Global building management and electrical infrastructure vendor offering integrated building automation, power, and OT security solutions. Broad incumbent in siganet's space via EcoStruxure platform, but competes as an OEM rather than a manufacturer-neutral planning firm.
• ENGIE Deutschland: German arm of a major European energy and facilities services group, providing technical building services, energy management, and TGA planning/implementation. Broad incumbent with comparable service offering to siganet across public and industrial clients but operating at much larger scale.
• ABB: Global electrification and automation vendor with building-side offerings in power distribution, KNX-based building automation, and OT security. Comparable to siganet across the power networks (KG 440) and automation stack but at vastly greater scale and as an OEM.
• Siemens Smart Infrastructure: Global broad-line provider of building automation, security, and OT solutions, including planning and integration services. A broad incumbent overlapping with siganet's stack across automation, security, and power — but competing primarily as a technology vendor rather than a manufacturer-neutral consultancy.
• Honeywell Building Technologies: Global provider of building automation, security, and OT solutions with strong presence in European institutional markets. Broad incumbent whose services overlap with siganet's portfolio across building automation and security integration, though delivered primarily as an OEM.

Direct peers

• Ingenieurgruppe Bauen: German engineering consultancy specializing in technical building equipment (TGA) planning across building automation, electrical, and HVAC disciplines for public and commercial clients. Closely comparable to siganet in service mix, project profile, and German regional focus.
• Schüßler-Plan Ingenieurgesellschaft: German engineering consultancy offering multidisciplinary planning including TGA, structural, and infrastructure engineering for public-sector clients. Directly comparable to siganet on German public construction project profiles and engineering-consulting service delivery model.
• Ingenieurbüro Hausladen: Bavarian-based engineering consultancy focused on building physics, energy efficiency, and building automation/controls planning. Comparable niche TGA engineering positioning with similar emphasis on energy-optimized and sustainable building operations for institutional clients.

Others

• TÜV SÜD Industrie Service: German testing, inspection, and certification body with adjacent building-services, energy audit, and OT/security certification offerings. Adjacent player — not a direct competitor in TGA planning, but relevant ecosystem participant where siganet's DIN 14675 and BNB Gold work intersects with certification and compliance services.
