Solaresbauen GmbH

What Solaresbauen GmbH does

Solaresbauen GmbH is a German engineering and consulting firm headquartered in Freiburg im Breisgau that delivers technical building equipment planning, energy concepts, building physics simulations, measurement-based energy analysis, and certification services for energy-efficient buildings. The firm serves four primary customer segments: residential construction companies (e.g., Schallstadt Weiermatten KfW-40 Plus housing, Campus Garden student housing), commercial and industrial clients (e.g., Brita production facility, Peter Lacke laboratory, Kirstein commercial building), public-sector clients (e.g., HS Offenburg RIZ, Gadamerplatz primary school), and private builders/owner communities. Underlying capabilities span TGA planning, Building Information Modeling, Passivhaus standards, KfW efficiency-house standards (40 Plus, 55), zero-energy design, and regulatory compliance documentation (GEG, EH-40, PV-Pflicht, EnEfG). The company also operates a research practice and provides technical monitoring and commissioning management to verify energy-savings outcomes post-implementation.

The firm's revenue model is professional services, billed on a project basis from initial energy analysis through planning, implementation, and ongoing monitoring. Go-to-market is direct, sales-led B2B engagement with no channel partner or reseller model, supported by reference-based credibility and selective public-facing marketing (university career events, project case studies). Pricing is not publicly disclosed. Operational footprint spans nine locations — Freiburg, Berlin, Friedrichshafen in Germany plus Straßburg, Paris, Colmar, Besançon, and Saint-Dié-des-Vosges in France — with approximately 130 engineers and technicians. The company is privately held (GmbH), reports no external funding rounds or parent-company relationships, and has no disclosed revenue figures in the available source material.

Core offering

Solaresbauen GmbH is a German engineering and consulting firm that develops energy concepts, performs building physics simulations and on-site measurements, and plans technical building services (TGA) using BIM for energy-efficient new builds, retrofits, and certification of climate-neutral buildings. The firm combines these core services with technical monitoring, commissioning management, regulatory compliance proofs (GEG, EH-40, PV-Pflicht, EnEfG), funding advisory (BEG, BEW, KfW, BAFA), and applied research to deliver verified, climate-neutral building performance.

Product overview

Solaresbauen GmbH is an engineering consultancy firm, not a software product company. The company offers a unified portfolio of energy consulting and technical building equipment planning services organized around energy-efficient building design. The core offerings include energy concepts combined with technical monitoring, building physics simulations, funding consultation for government programs (KfW, BAFA, BEG, BEW), analysis and measurement technology, TGA/BIM technical planning with contracting options, and certification services (GEG, EH-40, Passivhaus). Additional specialized services include technical commissioning management, BIM methodology implementation, and applied research. All services are delivered by a team of approximately 130 engineers and technicians across 9 locations in Germany and France.

Products and services

• Energiekonzepte & Technisches Monitoring Development of energy concepts for new builds and retrofits, combined with long-term technical monitoring and commissioning management to verify operational energy performance. Targeted at residential developers, commercial/industrial operators, and public-sector clients seeking climate-neutral, evidence-based building operation.
• Bauphysik & Simulationen Building physics analysis and thermal/hygienic simulations supporting energy-efficient design, including Wärmebrückenberechnung, Lüftungskonzepte, and Sommerlicher Wärmeschutz for property developers, architects, and planners.
• Beratung Förderung (BEG, BEW, KfW, BAFA) Advisory on German energy-efficiency incentive programs (BEG, BEW, KfW, BAFA), supporting clients through funding strategy, technical compliance, and application documentation to finance energy-efficient construction and retrofit projects.
• Analyse & Messtechnik On-site measurements and analyses (e.g., blower-door, thermography, heat-flow and tracer-gas methods) used for quality assurance, retrofit verification, and operational benchmarking. Targeted at builders, facility operators, and planners needing verified envelope and system performance.
• Technikplanung TGA, BIM & Contracting BIM-based technical building services (TGA) planning and contracting, covering heating, ventilation, sanitary, electrical, and renewable energy systems, coordinated through 3D BIM models. Targeted at developers, architects, and contractors executing energy-efficient new builds and complex retrofits.
• Nachweise: GEG, EH-40, PV-Pflicht, EnEfG Preparation of regulatory compliance proofs for German energy-efficiency mandates including GEG, EH-40 standards, PV-Pflicht, and EnEfG requirements. Targeted at developers, contractors, and public-sector clients needing certified regulatory documentation.
• Forschung & Grundlagen Applied research and fundamentals work on energy-efficient building technologies, conducted in collaboration with universities and industry partners to advance knowledge in building physics, low-energy systems, and renewable energy integration.
