IDN

What IDN does

IDN Fachplanungsgesellschaft mbH is a German private limited company (GmbH) operating as a planning and integration office (Planungs- und Integrationsbüro) for technical building equipment. Founded in 2006 as IDN GmbH and reorganized into its current legal form via a spin-off in 2024 under Managing Director Julian van der Laan, the firm is headquartered at Langer Weg 14 in Westoverledingen, East Frisia, Lower Saxony. Its offering centers on HOAI-compliant technical building equipment planning — covering basic determination, preliminary planning, design planning, permit planning, execution planning, tender preparation, construction supervision, and documentation — alongside a parallel system integration office that handles the interconnection and visualization of complex building technology systems. Service modules span classical electrical engineering, building automation, certified safety technology (intrusion and fire alarm), visualization systems, control systems, M-LAR fire protection, regenerative energy, media technology, video surveillance, telecommunications, and construction management / billing control.

The company's underlying technology is conventional engineering domain expertise rather than a proprietary platform or software product; its differentiator is positioned as industry-independent planning that is structurally free from manufacturer economic influences, intended to prevent supplier-driven cost inflation on client projects. Pricing follows HOAI fee schedules on a project-by-project basis, and revenue is generated through professional services engagements rather than product or license sales. The customer base is regional and concentrated in public and institutional buildings — churches, libraries, municipal buildings (Rathauser), healthcare and social-service facilities, and selected hospitality and commercial sites — with named reference projects including Johannes a Lasco Bibliothek Emden, Schweizer Kirche Emden, Seehotel Borkum, Ev. ref. Kirche Borkum, Taubblindenwerk, MVK-Klinik Schillig, and Rathaus Ostrhauderfehn. Go-to-market is direct B2B project engagement with no disclosed digital marketing channels, and the firm relies on WhatsApp Business for client communication.

Core offering

IDN provides HOAI-compliant technical building equipment planning (Technische Gebäudeausstattung) and system integration services for construction projects. Offerings cover the full HOAI service spectrum from basic investigation, preliminary and design planning through permit, execution, and tender planning, plus construction supervision and documentation. The firm additionally operates a System Integration Office focused on interconnecting and visualizing complex building technology systems in a vendor-independent manner.

Product overview

IDN is a planning and integration office (Planungs- und Integrationsbüro) for technical building equipment that operates as a unified service offering with interconnected competencies. The core offering consists of two integrated divisions: the planning office (Planungsbüro) providing HOAI-compliant technical building equipment planning services, and the system integration office (Büro für Systemintegration) handling visualization, interconnection, and integration of complex building technology systems. These two divisions work together to deliver industry-independent planning and implementation, ensuring economic considerations from industry suppliers do not drive up project costs. The service portfolio includes specialized modules for classical electrical engineering, building system technologies, certified safety systems (intrusion and fire alarms), visualization systems, control systems, fire protection (M-LAR compliant), regenerative energy, media technology, video surveillance, telecommunications, and construction management. The company was founded in 2006 and has evolved through several organizational changes, with the current IDN Fachplanungsgesellschaft mbH established in 2024 under the leadership of Julian van der Laan.

Broad incumbents

• AFRY Germany: European engineering, design and consultancy firm active in German building services, energy and infrastructure. Has overlapping TGA planning capabilities but competes primarily on larger industrial and public-sector projects.
• WSP in Germany: Global professional services firm with German building-services engineering teams covering electrical, mechanical and fire-protection planning. Competes for larger institutional TGA mandates where IDN also participates.
• Drees & Sommer SE: Large German engineering and consulting firm with deep TGA planning, building automation, and energy-efficiency practices. Competes with IDN on institutional projects but offers a far broader portfolio spanning real estate, infrastructure and digital.
• Sweco Germany: European engineering consultancy with German operations covering building services, energy and sustainability consulting. Comparable to IDN in TGA planning scope but with much broader geographic and disciplinary reach.
• Arcadis Germany: Global design, engineering and consultancy group with substantial German TGA and building-services engineering capabilities. Overlaps with IDN on electrical and MEP planning but operates at multinational scale with cross-disciplinary offerings.
• Ramboll Germany: International engineering and consulting group with German building services and sustainability practices. Comparable in TGA technical scope but typically engaged on larger, multi-disciplinary engagements than IDN's regional focus.

Direct peers

• ZWP Ingenieur-AG: German engineering consultancy specialized in technical building equipment (TGA) and MEP planning, with HOAI-compliant service offerings. Highly comparable to IDN in core scope (electrical, building automation, safety systems) but operating at national scale.
• Planungsgruppe M+M AG: German engineering firm focused on technical building equipment planning and energy concepts, delivering HOAI services similar to IDN. Direct competitor for institutional and commercial TGA planning mandates in Germany.
