WHY RENALDOBecause a building project
Because a building project
belongs together.
RENALDO brings predefined work items, prices, durations and quantity rules for residential construction. Your building data becomes a prepared starting point: review, refine and reuse it for estimating, tendering and scheduling. Less manual preparation and data transfer, for new builds and renovation.

Work item × quantity × unit price: Renaldo connects building and room data with regional trade prices. The cost-confidence indicator shows how reliable your calculation is and which details are missing for the next level of accuracy.
A figure to inform your decision, with a visible assessment of the calculation.
One project view.
For everyone building together.
Developers, site managers, designers and trades work on the same project. Information and updates stay connected to it. In the site portal, trades see their tasks and report progress or delays through a link, without needing to create an account.

BUILT FROM CONSTRUCTION EXPERIENCEPrepare well.
Meet the people behind Renaldo ↗
Prepare well.
Build with the right rhythm.
Gregor Loukidis and Ronald Meyer combine platform development with experience in serial renovation, construction logistics and the Sanierungssprint. That combination shapes Renaldo, from early calculations to delivery on site.
The Sanierungssprint brings preparation, construction logistics and coordinated scheduling together. Our renovation-coach training passes on this knowledge to help homeowners and professionals move projects forward on site.

Start with your own building and an initial cost estimate.
Start for freeCONNECT EARLY DESIGN AND PROFESSIONAL PLANNING
Your designer starts with a model.
A prepared starting point reduces repeated data entry, especially in renovation. RENALDO connects the building model, room schedule and draft drawings. Your designer receives the model via IFC, reviews it and develops the architectural design and subsequent planning.
Start with the existing building
Available LOD2 building data and a hypothetical room schedule provide an initial model. Existing drawings, surveys, scans or IFC data refine that starting point.
Hand over the full model
IFC4 export includes the components present in the model: walls, slabs, roof, stairs, windows and doors, plus spaces, quantities, materials and properties. Draft drawings from the Planning Center support the handover.
Review and develop the design
The designer checks dimensions and existing conditions, adds a measured survey where needed and makes the final architectural adjustments. Professional planning builds on the early design.
LOD2 and a hypothetical room schedule are early design assumptions, not a measured survey. Spaces without a known location remain records without invented geometry. The designer checks import and editability in the chosen CAD system and remains responsible for professional review and approval.
Module: Plan & Calculate. File handover follows the project release rules for plans and data exports; a trial alone does not unlock IFC downloads. Housing and homeowner project and package rules apply.
HOUSING · PORTFOLIO & STRATEGY
Compare climate targets and costs over time.
Which package suits the building and meets the climate target? Compare its carbon trajectory with the selected target pathway, identify gaps and prioritise portfolio investments.
Lifecycle costs beyond construction
Assess construction and measure costs for materials and labour, maintenance, replacement and residual value alongside energy and carbon costs. Adjust horizon and discount rate, compare present value and annual costs, and assess carbon abatement costs.
Operational and embodied emissions
Reviewed component quantities add embodied emissions in the project. Sources, measured data and estimates remain traceable. The public demo shows climate pathways and simplified cost analysis; it does not replace a verified building lifecycle assessment.
Included in Housing Portfolio and Housing Komplett. Housing Komplett adds procurement, scheduling and renovation-related resident communication. Operate alone does not include portfolio strategy.
CONTRACTORS · WORK PREPARATION
From material item to timely ordering.
Reuse your article library
Maintain article number, manufacturer, supplier, unit and price for materials. Import Excel and CSV lists into your library with column mapping and preview. Material data stays connected to line items and work preparation.
Include lead times in the schedule
Set lead times in working days for materials, line items, trades and company defaults. Order planning shows sampling, release and latest ordering dates before installation. Changes to source data flag existing orders for review.
Plan & Calculate covers material items and library import; Schedule & Quality covers order planning. The contractor package also includes bid costing, the 3D offer room and subcontractor management. Packages from the client tender require Bid costing and Tender & Account.
