For energy consultants connecting building data, renovation options, costs and funding. Start with advisory work and add procurement or construction support when needed.
Workspace / Renovation optionsJLAdvice is the starting point. Add modules when you also support clients through procurement or construction, using the same building data.
The foundation for energy advice: capture buildings and quantities, cost renovation options and prepare advisory documents.
Optional procurement support: turn checked work items into bills of quantities, compare offers and review invoices.
Optional renovation delivery support: connect schedules, inspections, site walks and progress in the project.
Shared foundation: building data, documents and collaboration connect the modules. Invited participants collaborate for free within their project role; independent professional editing requires the appropriate modules. Collaboration is not an additional module.
Your mandate determines the scope. Analysis and preparation need no active project slot. Procurement or construction delivery require the corresponding modules and project capacity.
Assess renovation options using building data and predefined work items and cost assumptions. Review assumptions and add your expertise. Procurement, schedules and SAM site walks are available through the corresponding modules when your mandate includes delivery support.
Use the model and room schedule for quantities and costs. Hand over all modelled components to your designer via IFC, starting from LOD2 and a hypothetical room schedule.
See the workflow ↘02Use building models, preliminary calculations and draft plans as a shared starting point. Review with specialists, refine and reuse for costs, procurement and delivery.
See the workflow ↘03Building data and predefined work items produce the estimate. Review quantities and scope, then reuse the same basis for tendering.
See the workflow ↘04Consider measures, costs and potential funding together. Turn reviewed options into a renovation pathway.
See the workflow ↘05Generate the specification, invite suppliers and compare price and completeness – against the Renaldo market price per item, even before the first bid.
See the workflow ↘06Quantity-based durations and predefined dependencies generate the sequence. Adapt takt and capacity to the project.
See the workflow ↘The building profile, energy metrics and renovation options form a shared basis for advice. Data sources and validation remain visible, while selected measures feed into project costs.
Use building data from sources such as IFC, EVEBI, Hottgenroth or scans and review its provenance in the building profile. Certificate values and estimated energy metrics remain distinguishable.
Connect renovation options to cost planning, or import measures from an existing iSFP and map them to work items. The Renaldo renovation roadmap supports the advice; it does not replace an iSFP.
For new builds, the focus is the building model, service checklist and appropriate funding planning. The energy profile and renovation calculations are intended for existing buildings.
Workspace / Renovation optionsJLImport energy certificates with energy metrics, CO₂ values, certificate type and expiry date. Available certificate values take precedence over model values; estimates and sources stay visible.
Go beyond the advice: roadmap → funding-compliant bill of quantities, online contractor search and supervision through to delivery – for additional fees. Deliverable immediately with the app, and professionally underpinned by the retrofit-coach training.
Not an anonymous software house: Gregor builds Renaldo directly along the working practice of energy consultants. In 60 seconds he explains why. (Video in German.)
Energy metrics, retrofit calculator, GEG check and SAM – advise properly, before the roadmap even exists.
Roadmap → funding-compliant bills of quantities and online contractor search – more service, more fee income.
Enter the address – Renaldo shows the building's current efficiency class and energy demand (kWh/m²a). The AI retrofit calculator proposes energy measures with costs, savings and the jump in efficiency class (before → after). Right there in the first conversation, long before the official roadmap exists – as a PDF, or live with the client.
Every relevant building figure at a glance – as a compact profile you can hand over as a PDF at the touch of a button, to external advisers too: efficiency class, energy demand (kWh/m²a), heating system, roadmap flag, floor area, rooms and storeys, build year and building class – plus areas, geometry and photovoltaics where present. It stays transparent where the data came from (LoD2, Doorbit scan, IFC, magicplan, EVEBI, Hottgenroth or manual entry) and whether it has been properly validated.
Renaldo checks, per building element – external wall, roof, windows, ground slab – whether the planned measures meet the requirements of the GEG. Including the 65 % renewables rule for heating, the boiler-replacement obligation by build year, and the deadlines of municipal heat planning. So your advice is compliant without leafing through the statute.
For new-build schemes too: the right new-build funding (the German climate-friendly new build scheme / KFN, QNG, EH40) is taken into account – including the assumptions you are professionally responsible for. So you can support clients from retrofit through to new build out of one app.

Start for freeBuilding quantities and selected work items connect with prices, helping you cost renovation options and discuss priorities, budgets and potential funding with your client.
Quantities from the building, prices from the market.
Real-time checking of all BAFA and KfW rules, including a guided qualification for the bonuses (speed, heat pump, roadmap, municipal). You see per measure what works under the funding logic. And the funding tracker keeps every application, deadline and piece of evidence in view – with reminders for you and for your client.
Workspace / Cost planningJLQuantities from the building, prices from the market.
You choose the work item. The quantity comes from your building and room data, the price from real regional contractor rates. No counting windows, no calculating wall areas.

And the funding tracker keeps every application, deadline and piece of evidence in view – with reminders for you and for your client.
Renaldo thinks about every retrofit from the end backwards: a contractor's invoice is always work item × quantity × unit price – Renaldo determines all three and turns them into a reliable, tender-ready cost plan.
Import the existing building or enter the address, assess it energetically (retrofit calculator, GEG check), configure the measures and calculate the funding – until the cost estimate holds up.

Energy consultants use Renaldo in two ways: to make advice and funding management significantly more efficient – and to offer genuine retrofit supervision as a new, billable service.
Workspace / CollaborationJL✓ Every feature for 30 days – no credit card. Plans carry a watermark during the trial.
Built by practitioners: 10 years of retrofit project management plus 30+ years of construction expertise.
Energy consultants use Renaldo in two ways: to make advice and funding management significantly more efficient – and to offer genuine retrofit supervision as a new, billable service.
Energy advice and funding management – from before the retrofit roadmap onwards. Retrofit calculator, GEG and BAFA checks, deadline tracker and AI bid checking: less spreadsheet work, fewer mistakes, more projects in the same time.
That is exactly what Renaldo is for – energy advice, funding and retrofit supervision in one app.
The quantities come from the building data, the prices from the market — and out of that comes the bill of quantities for the tender, directly.
Straight from the configuration into the tender.
Your configuration becomes a tender-ready bill of quantities across every trade — with long descriptions, quantities and unit prices. From there straight into the local search and the online request.
Three pillars, two levers: energy advice and funding management (pillars 1–2) make your core business more efficient, retrofit supervision (pillar 3) opens up a new revenue stream – all in one app, from the first energy assessment to delivery.
Funding calculator, BAFA requirements check, deadline tracker and AI bid checking – claim every grant safely.
Already working with Hottgenroth, EVEBI and the rest? Renaldo takes your building and element data straight in – no retyping. Or just enter the address and Renaldo loads the official LoD2 building data at the click of a mouse. Which means the data basis for energy metrics, the retrofit calculator and the GEG check is ready in minutes rather than hours.
SAM answers your technical questions on German building-energy law, BAFA/KfW funding, building physics and standards – in the context of the project. Role-adaptive: it explains things to your client in plain language, and answers you in expert terms. So you have the answer to hand without a long search.
Renaldo gives you the minimum U-values for the individual BEG measures and lists the insulation specified per element with its estimated U-value. So you can see immediately whether your measure meets the BAFA requirement – before the quote goes out.
Upload an existing retrofit roadmap – Renaldo reads out the measures and matches them automatically to ready-made, BEG-compliant bills of quantities from our works database. Usable straight away for contractor requests, without spreadsheet DIY.
Once the measures are settled, you approach contractors in one click: local search + a ready-made BEG-compliant bill of quantities + an online request. Optional as an additional service for your clients – a clear added value that justifies your fee.
Site supervision, tasks, document storage and the rest are further down under “Also on board”.
Pour your services into a complete proposal, contract terms included – with modular service blocks that match your qualifications: from energy assessment (a retrofit roadmap with or without a building scan) through funding-application support to Renaldo service packages (optionally on the German HOAI fee scale too). Quantities and prices are pre-filled and editable – and via the basket, the costs flow straight into your client's budget. Once priced in, fees get questioned less and awarded faster.
Other tools make energy advice more efficient. Renaldo makes it collaborative. As soon as you invite a client, they can upload documents, follow progress, configure measures further and request contractor quotes – and you still stay in control.
Assessments for apartment blocks, cleanly structured: buildings with cores and residential units, each with its own room schedule. Energy metrics, measures and grant amounts scale per unit – rather than everything in one flat list.
Document management, task management, a mini CRM for your projects and clean PDF exports – the full project-management set around your advice.
Who does what by when – with owners, due dates, status and push reminders for the client and for you.
All your projects at a glance – with status, next steps and filters by phase, funding programme and client.
Retrofit proposals, cost estimates, lists of measures and funding overviews – cleanly exported for your client meetings.
Servers and database in Germany, files in the EU. You and your client can export or delete your data at any time.
Exported from the basket with a purpose of use – as the energy consultant you can validate and sign it for the financing application.
In the Renaldo Academy you keep up to date with webinars and tutorials on GEG/BEG changes, funding updates and Renaldo workflows – so your advice stays current and defensible. Currently in German.
From a database covering more than 20 trades.
From your building and room data.
Real regional contractor rates.
The same three phases guide you inside the app: the task view shows what's next in each phase.
Approach contractors through the local search using the BEG-compliant bill of quantities, and check the bids for funding eligibility with AI.
Bring clients into the project, deliver it together, track funding deadlines and check invoices – you stay in control.

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.
Available LOD2 building data and a hypothetical room schedule provide an initial model. Existing drawings, surveys, scans or IFC data refine that starting point.
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.
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.
When your mandate extends beyond advice, Tender & Account turns checked quantities and work items into a bill of quantities and supports offer comparison and procurement.
Every bid measured against your own bill of quantities.
Upload contractor bids as PDFs – the SAM AI checks in seconds whether every minimum technical requirement for BEG funding is met (U-values, COP, seasonal performance factor, insulation thicknesses, material specifications). A single item caught justifies Renaldo for a whole year.
