What eboek does

ebök GmbH is a Tübingen, Germany-based engineering consultancy founded in 1993 that provides integrated building physics (Bauphysik), technical building services (Haustechnik), and energy concept (Energiekonzepte) planning for new construction, renovation, and district-scale projects. The firm combines thermal building simulation, air tightness testing (Blower Door per DIN EN ISO 9972), GIS-based energy mapping, and Passivhaus certification expertise — capabilities it has built since 1991 — into a single multidisciplinary offering spanning concept, planning, construction supervision, and facility optimization. Its core technology stack relies on software-supported engineering simulations and GIS data processing rather than proprietary platforms or AI/ML systems; the company's differentiation is engineering judgment and regulatory know-how, not software products.

The firm operates a sales-led, direct-engagement go-to-market targeting German municipalities, public institutions, housing cooperatives, educational facilities, and private developers. Revenue is generated through project-based consulting engagements billed under HOAI (Honorarordnung für Architekten und Ingenieure) fee structures, with no public pricing disclosure. Customer concentration is diversified across many municipal logos, but skewed toward public-sector clients whose capex is tied to government budgets and federal programs such as KfW and BEW. The firm is currently expanding service lines around the federal Heat Planning Act (WPG) and BEW heat network funding, and has extended operations from its Baden-Württemberg home base into Bavaria, Hesse, North Rhine-Westphalia, and Rhineland-Palatinate. With approximately 35-40 employees, it is a small, employee-owned GmbH (Managing Directors Matthias Laidig and Michael Keppler) with no external investors, no parent company, and a profit-sharing ownership model restricted to active employees.

Core offering

ebök GmbH delivers engineering consulting services for the rational use of energy in building construction and operation. The firm plans and advises across the full project lifecycle — from conception and planning through construction supervision to facility optimization — for both new builds and renovations, combining building physics (Bauphysik), technical building equipment (Haustechnik: heating, ventilation, sanitation, cooling, MSR), and holistic energy concepts (Energiekonzepte) including municipal heat planning, federal heat network funding support (BEW), and sustainability certification.

Product overview

eboek is a planning and consulting engineering firm offering a unified portfolio of building physics, technical building equipment, and energy concept services. The core offerings are organized around three pillars: (1) Energiekonzepte — energy concepts covering municipal heat planning, BEW (federal heat network funding), neighborhood concepts, and renovation roadmaps; (2) Bauphysik — building physics services including thermal physics, building and room acoustics, simulation, and measurements; and (3) Haustechnik — technical building equipment covering heating, ventilation, sanitation, cooling, and MSR systems. Cross-cutting services include Nachhaltigkeit (sustainability certifications, LCA, circular economy), Sanierung (renovation for old buildings, monuments), and specialized offerings like Blower Door testing and Passivhaus certification. The company does not operate a software product but delivers engineering consulting services for sustainable building.
