Broad incumbents

• Drees & Sommer SE: Stuttgart-headquartered, large German engineering and consulting firm with broad capabilities including MEP/TGA planning, sustainability, and digital construction. Comparable in regional base and overlap on energy-efficient HVAC/building automation mandates, but operates as a multi-thousand-employee incumbent well beyond IBW's niche scale.
• Krebs + Kiefer Ingenieurgesellschaft mbH: Darmstadt-based German engineering consultancy with national footprint covering structural, infrastructure, and building services engineering. Comparable in HOAI-regulated engineering services for German public and private clients, though far broader in scope than IBW's TGA specialization.

Direct peers

• ZWP Ingenieur-AG: German MEP/TGA planning specialist with offices in Stuttgart, Berlin, and other locations. Closely comparable in core service portfolio (HVAC, heating, sanitation, building automation) and customer segments (public sector, commercial, healthcare), though materially larger in scale.
• Assmann Beraten + Planen GmbH: Dortmund-headquartered German MEP/TGA planning consultancy with full HOAI LP 1-9 service coverage across HVAC, heating, sanitation, and building automation. Directly comparable in service scope and German public/private client mix, though operating at significantly greater scale.
• Planungsgruppe M+M GmbH: Böblingen-based German MEP/TGA engineering consultancy specializing in ventilation, HVAC, and CAD planning. Directly comparable as a same-category TGA planning firm; Managing Director Rolf Gesell himself worked there previously as CAD administrator and project engineer, indicating direct professional overlap in services and tooling (C.A.T.S., AutoCAD).
• TGA Consulting München: Munich-based TGA engineering consultancy where Managing Director Rolf Gesell previously served as project engineer and CAD group leader, including work on the Allianz Arena Munich RLT systems. Directly comparable in TGA planning focus and tooling stack.
• Ingenieurbüro Hausladen GmbH: Munich-based German engineering consultancy specializing in sustainable building services, HVAC planning, and energy consulting. Comparable to IBW in renewable integration expertise, hospital/laboratory project references, and HOAI-aligned TGA planning services.
