Institut für Baubiologie + Nachhaltigkeit IBN Unabhängige private GmbH

What Institut für Baubiologie + Nachhaltigkeit IBN Unabhängige private GmbH does

Institut für Baubiologie + Nachhaltigkeit IBN is a privately held German limited liability company (GmbH) founded in 1983 and headquartered in Rosenheim, Bayern, with 13 employees. It operates as an independent continuing education and certification institute focused on building biology (Baubiologie) — the study of how built environments affect health and sustainability. The institute's flagship offering is the state-approved, AZAV-certified Fernlehrgang Baubiologie IBN, a ~1-year distance learning program priced at €3,750 that qualifies graduates as certified Baubiologe/Baubiologin IBN. This core program is supplemented by three specialized seminars (Messtechnik, Energieberatung, Raumgestaltung), certification services for construction methods and buildings, and a network of consulting locations (Beratungsstellen) across Germany and internationally.

The company's technology stack is built on commodity third-party tools: Moodle-based LMS for course delivery, Zoho CRM for customer management, WordPress with FacetWP for the consulting directory, IONOS hosting with Cloudflare, Klick-Tipp for email marketing, and Zoom for live seminars. Its proprietary assets are content-driven — the 25 Leitlinien der Baubiologie (translated into 15 languages), the SBM-2024 measurement methodology, and the Baubiologie Magazin online content library. Distribution is multi-channel: direct website self-service enrollment, free info webinars, AZAV-funded employment agency referrals, an international partner network (ANAB in Italy, IEB in Spain, Bioedilizia Südtirol), and social media presence across Facebook, Instagram, YouTube, and Vimeo.

Revenue is generated primarily through course fees (€3,750 per Fernlehrgang enrollment with optional printed materials and exam fees), seminar fees, certification and expert opinion services, and consulting network referrals. The customer base consists mainly of construction professionals (architects, engineers, craftsmen), students, and health-conscious individuals undertaking building or renovation projects. The company is managed by Stefan Sellner (Geschäftsführer) and maintains a strict independent and neutral positioning with no disclosed external investors or parent company.

Broad incumbents

• DEKRA Akademie: Continuing education division of DEKRA, providing certified courses including in construction, energy, and environmental topics. Comparable in regulated, AZAV-aligned training delivery to working professionals, though operating at much greater scale.
• Deutsche Gesellschaft für Nachhaltiges Bauen (DGNB): L Germany's leading sustainable building certification system with extensive training programs for auditors and consultants. Comparable as a standards-setting and practitioner-education body, though broader (whole-building sustainability) versus IBN's health/Baubiologie niche.
• TÜV Rheinland Akademie: Continuing education arm of TÜV Rheinland, offering certified professional training including in building, energy, and sustainability domains. Comparable in practitioner certification and regulatory-grade credentials, though part of a much larger certification conglomerate.

Direct peers

• Studiengemeinschaft Darmstadt (SGD): Major German Fernlehrgang provider offering state-approved distance learning across many disciplines. Comparable in distance learning delivery model, AZAV certification mechanics, and professional upskilling audience, though without the building biology specialization.
• Sentinel Haus Institut: German institute focused on healthy/sustainable building certifications, product testing, and practitioner education. Closely comparable in mission (Baubiologie/healthy building), target audience (architects, builders, manufacturers), and certification-driven business model.
• ANAB – Associazione Nazionale Architettura Bioecologica: Italian national association for bioecological architecture and IBN's official Italian partner. Comparable mission (healthy/sustainable building education and practitioner certification) and acts as both a peer and a distribution channel for IBN standards.
• Bildungswerk Bauschaden-Expertise (BBE): German continuing education provider focused on construction, building damage, and building health topics for trades and engineers. Comparable audience (Baufachleute) and Fernlehrgang-style certification programs.
• ILS – Institut für Lernsysteme: One of Germany's largest distance learning institutes, offering state-approved Fernlehrgänge with similar pricing tiers and AZAV-style funding mechanics. Highly comparable on GTM (self-serve online enrollment, installment billing) though broader in subject portfolio.

Regional players

• Ökohaus / Ökozentrum NRW: Regional German continuing education center focused on ecological and healthy building. Comparable niche in Baubiologie-style practitioner training, though primarily regional (NRW) rather than national/international.

Others

• FernstudiumCheck: Germany's leading distance learning comparison and review platform, where IBN's Fernlehrgang is listed and ranked. Comparable as an ecosystem participant in the same Fernlehrgang buyer journey, though not a direct training competitor.
