What Team Oekoplan does

Ökoplan Architekten PartG mbB Kunad.Riederer (operating as Team Oekoplan) is a small, family-owned German architecture practice headquartered in Karben, Hesse, founded in 1984 by Verena Kunad and Klaus Riederer. Since 2023 the firm has operated as a PartG mbB partnership led by co-founder Verena Kunad and her daughter Carla Riederer, combining more than 40 years of experience with current specialist knowledge. The practice employs approximately seven people and serves the Rhine-Main metropolitan area from Gießen to Offenbach.

The firm's core offering is integrated architecture and energy consulting across all HOAI performance phases, organized around five service lines: ecological building (ökologisches Bauen), building in existing structures (Bauen im Bestand), monument preservation (Denkmalpflege), new construction (Neubau) including efficiency-house construction, and certified energy consulting (Energieberatung). Supporting services include expert opinions and building valuations (Gutachten). Both partners are listed with BAFA as subsidized energy advisors, registered in the KfW Energy Efficiency Expert List, and certified by the WTA for heritage building preservation, giving the firm formal access to federal and state subsidy programs that act as demand catalysts.

Revenue is generated through project-based professional services fees billed under multi-year contracts aligned to HOAI work phases; no public pricing or rate card is disclosed. The customer base is horizontally segmented across private residential property owners, commercial clients, and public authorities/municipalities, with go-to-market executed via a sales-led, personal-advisory model. Distribution is direct from the Karben office to clients in the regional Rhine-Main catchment, supported by a website, an educational Ratgeber guide section, and a multi-platform social media presence. The firm maintains a regional network of qualified local craft businesses (Handwerksbetriebe) for project execution and is a member of the Architekten- und Stadtplanerkammer Hessen.

Expansion highlights3 records

Emerging players

• co2online GmbH: Non-profit climate advisory organization offering energy consulting and subsidy guidance for residential buildings in Germany. Comparable to Ökoplan's residential-focused energy consulting and subsidy advice (BAFA/KfW), though without the architecture practice integration.
• Verbraucherzentrale Energieberatung: Consumer energy advisory service providing subsidized energy consulting for residential buildings in Germany. Comparable to Ökoplan's BAFA-listed energy consulting offering for residential and existing buildings, though delivered as a broad public service rather than an integrated architecture-plus-energy practice.

Direct peers

• Transsolar KlimaEngineering: German engineering firm specializing in climate, energy, and sustainability consulting for buildings. Closest functional peer to Ökoplan's energy consulting practice, with both firms advising on building physics and energy efficiency for architectural projects, though Transsolar serves much larger commercial projects.

Broad incumbents

• Heinle, Wischer und Partner: German architecture and engineering firm with offices in several German cities. Comparable to Ökoplan as a German architecture practice covering full project phases including renovation and energy-related planning, but operating at much larger scale.
• HPP Architekten: Major German architecture firm with offices across Germany including Frankfurt, with strong practice in renovation and public buildings. Comparable because it operates in the Rhine-Main area and handles both new construction and existing-building projects, similar to Ökoplan's 'Bauen im Bestand' focus.
• GEF Ingenieur AG: German engineering firm providing planning, energy consulting, and building performance services including for existing buildings. Comparable to Ökoplan in combining engineering with energy consulting for renovation projects, though operating at a larger scale.
• Bollinger + Grohmann: German engineering and architecture firm with strong focus on sustainable and energy-efficient building design. Comparable to Ökoplan in combining architectural and engineering/energy expertise, but at a much larger scale and broader international footprint.
• Hascher Jehle Architektur: German architecture firm with deep practice in public, commercial, and renovation projects. Comparable to Ökoplan in handling projects across HOAI phases including existing-building work, though operating at a larger scale and project size.
• agn Niederberghaus & Partner: Large German architecture and engineering firm with multiple offices including in the Rhine-Main region. Overlaps with Ökoplan in offering architecture and energy-relevant consulting for both new construction and renovation, but at substantially greater scale and with broader geographic reach.
• Kadawittfeldarchitektur: Established German architecture firm with offices in Aachen and Berlin, working across public, commercial, and cultural buildings. Comparable as a German generalist architecture practice, though much larger in scale and broader in scope than Ökoplan.
