Aggregate
Public reference datasets are queried and reconciled around a single building, with no technical input required.

Understand a building before investing in it
Geominnov aggregates public building data — energy ratings, land registry, urban planning, natural and climate risks — to produce an energy diagnosis, prioritised works and territory-wide oversight.
01Product challenge
The data exists, nobody cross-references it.
Energy ratings, land registry, urban planning, natural disasters, solar potential: it's all public, but scattered across technical portals that no one opens before buying or renovating.
The result: works decided on intuition, risks discovered too late, and local authorities with no fine-grained view of their housing stock.
02Product response
One address, one complete diagnosis.
Assess
Energy performance, heat loss, natural risks and climate projections are brought together into readable scores.
Decide
Prioritised works, estimated savings, available grants and compared scenarios at the scale of a housing stock.
03Key modules
From home to territory.
Home energy assessment
Address, property type, year built, equipment: the form guides the owner and produces a complete energy assessment.
Aggregated public data
Official ADEME energy ratings, land registry, urban planning, solar potential, fibre eligibility: reference datasets are queried and reconciled automatically.
Risks across France and the world
Interactive maps of natural disasters, history, timeline and statistics by municipality, up to a global scale.
Property risk score
Flooding, heatwaves, drought, hail, seismic zones, polluted sites, natural-risk and flood-risk plans synthesised into a single readable score.
Climate projections
The property is projected against upcoming climate scenarios, to help decide on works based on future risk.
Recommendations and action plan
Prioritised works, estimated savings, profitability and a project simulation with associated grants and financing.
3D and thermal visualisation
Building modelling, cross-section view, heat loss and an immersive VR view to make the diagnosis obvious.
Street explorer
Explore the building stock through street-level panoramas, target a building and overlay its data.
Professionals space
Directory and dedicated space for tradespeople: sign-up, detailed profile, matching with renovation projects.
Territory dashboard
For local authorities: housing stock analysed, filters, compared renovation scenarios, quantified impact and collective reports.
04Real scenarios
The decisions the platform unlocks.
The product wasn't built around datasets, but around the moments when a decision gets made: buying, renovating, arbitrating a public budget.
Every screen answers a precise question and ends with a possible action, not a raw table.
Homeowner
Know what to do first
Rather than an isolated quote, the homeowner gets a ranked list of works with estimated savings and return on investment.
Property purchase
Buy with full knowledge
Real energy rating, natural risks, climate projections and energy costs are gathered before signing.
Local authority
Steer the renovation of a housing stock
The local authority identifies vulnerable homes, simulates scenarios and measures energy and carbon impact.
Professional
Meet qualified projects
Tradespeople access already-diagnosed requests, complete with the building's technical context.
05Journeys and roles
Three audiences, one shared database.
Individual
They assess their home, understand its heat loss and track their renovation plan in their history.
Local authority
They use a territory dashboard, collective reports and compared scenarios across their housing stock.
Professional
They publish their profile, receive contextualised requests and work on already-scoped projects.
06Day to day
What the platform changes in practice.
- A complete diagnosis in a few minutes, with no prior site visit.
- Natural and climate risks read at the scale of the building.
- Works prioritised by real savings, not intuition.
- An entire housing stock manageable from a single map.
07Kreapp's approach
A lot of data, a simple interface.
The challenge isn't displaying public data, but making it understandable: maps, scores, 3D and thermal visualisations were designed to be read without technical expertise.
Delivered in short cycles, datasets added one by one, and validated with the homeowners, tradespeople and local authorities who use it.
