Why Energy Consultancies Outsource Modeling
Auditors and consultants receive plans as PDFs, DWGs or scans. Before any calculation can start, someone has to rebuild them as a model with correct wall thicknesses, floor heights, openings and room volumes. Hiring locally is slow and costly, and generic CAD outsourcing often returns models that fail your own checks. Ribhus is a small civil engineering studio that does only this one job, and does it to a standard you can build on.
We absorb peak workloads without hiring or training, so deadlines stop depending on headcount.
Every model goes through dimension and standards checks, so errors are caught on our side.
A fixed quote per project instead of hourly billing surprises.
What We Build
High-precision parametric models engineered for German and European building energy auditors, architects, and engineering consultancies.
PDFs, DWG files or paper scans converted into coordinate-locked ArchiCAD or Revit models with exact wall assemblies and zero dimensional drift.
Engineered specifically to feed thermal calculation engines directly. Continuous envelope definitions, room volume extractions, and zone assignments.
Hand-drawn blueprints, historical municipal archives, or 3D LiDAR point cloud scans reconstructed into clean, coordinate-referenced digital twins.
CAD drawing sets, floor plan redesign, BOQ volume calculations according to DIN 277, and interactive BIMx presentation models from a centralized model.
Clear, Predictable Turnaround
Upload PDFs, DWG files or scans at any scale. Everything stays under strict NDA upon request.
Within hours you receive one price based on floor area, level of detail and complexity. No hourly billing surprises.
Standard residential models arrive in 24–48 hours. Larger multi-storey or commercial projects get their own timeline in the quote.
Every model is reviewed against our 5-point verification protocol before delivery:
Verified Engineering Deliverables
Every wall, opening, and room volume is geometrically modeled for direct import into thermal simulation engines.
Coordinated model covering 3 buildings (2,682 elements, 1,364 walls, 6,595.83 m³ volume, 232 thermal zones) built as the exact data source for EPC audits and thermal evaluations.
11,073 m² across 12 levels modeled for energy simulation from day one. Direct IFC4 export into thermal engines with zero geometric approximations (538 windows, 171 doors).
Single-family high-efficiency villa modeled in ArchiCAD with continuous thermal envelope assemblies, U-value classifications, and solar exposure detailing for GEG audits.
Continuous production of residential and commercial BIM models at LOD 200–300 in ArchiCAD with IFC 4.3 export for German energy audit compliance.
Steel gusset plate and girder connection detailing: 17 DWG sheets delivered in 8 days from structural calculations under IS 800:2007 with zero rework.

Vollständig geschlossene thermische Gebäudehülle mit Dachschrägen, Gauben und maßgenauen Fenstern/Türen für iSFP und GEG-Nachweise.
Vollständiges 3D-BIM-Gebäudemodell mit allen Innenwänden, Geschossdecken, DIN 277 Raumstempeln und Zonen für Raumheizlastberechnungen.
Transparente Festpreise
Verbindliche Festpreisangebote vor Beginn. Keine Stundensurprises, 100% Passgenauigkeits-Garantie.

Wir wissen: Ein CAD-Modell nützt Ihnen nur, wenn die Hüllflächen und Raumgeometrien in Ihrer Software (Hottgenroth, Solar-Computer etc.) sofort stimmen.
Sollte ein von uns geliefertes Modell beim Import Geometrie- oder Schichtenfehler aufweisen, beheben wir das Problem innerhalb von 12 Stunden kostenfrei. Kann das Modell dennoch nicht für Ihre Berechnung genutzt werden, erhalten Sie 100 % des Rechnungsbetrags erstattet.
Größere Nichtwohngebäude oder historische Papierpläne werden individuell kalkuliert. Sie sind unsicher, welches Paket passt? Senden Sie uns einen Bestandsplan – Sie erhalten innerhalb weniger Stunden eine Einschätzung.
About Ribhus
Founded in 2026 by civil engineers, Ribhus is a specialized BIM and digital building support studio working with architecture firms, engineering consultancies and building energy professionals across Europe.
We help transform architectural drawings, scanned documents and existing building information into accurate, structured and coordinated digital models. Our work focuses on architectural BIM modelling, 2D-to-3D conversion, scan-to-BIM workflows and IFC-based deliverables.
With practical experience across international BIM workflows, we understand that a reliable model is more than just a 3D representation. It needs to reflect the actual building geometry, wall assemblies, room dimensions and spatial information required for downstream design, coordination and building-performance assessments.
At Ribhus, we aim to make dependable BIM support more accessible, flexible and efficient for firms that need additional modelling capacity without expanding their in-house teams.

Clear Answers
No. We build the model your calculation starts from. The calculation and any certificate stay with your team.
PDFs, DWG or DXF files, scans and photos of hand-drawn plans. Clearer sources give faster results, and we flag unclear dimensions before we model them.
ArchiCAD (.PLN), Revit (.RVT), IFC 4.3, and DWG or PDF drawings. BIMx is available for client review.
LOD 200 and LOD 300. If you need something else, say so when you ask for the quote.
Standard residential models take 24–48 hours from the moment we have complete drawings. Larger projects get a timeline in the quote.
Every model is checked for dimensions, wall thicknesses, floor heights, standards and a clean IFC export before it reaches you.
We sign an NDA on request, use your files only for your project, and delete them when you ask. Our privacy policy explains how we handle personal data.
One room, one floor plan or one scanned PDF, modelled free. No card, no contract. It lets you judge accuracy and speed before committing.
Risikofreier Start
Senden Sie uns einen Raum, einen Grundriss oder einen Scan (bis 50 m²). Wir modellieren ihn kostenlos, damit Sie Passgenauigkeit und Geschwindigkeit direkt in Ihrer Software prüfen können. Keine Zahlungsdaten, kein Vertrag.
