Climate risk data for real estate investors
HOMAI shows the physical climate risk of a Norwegian property before you commit capital: flood, landslide, precipitation and storm exposure, roof condition and official registry facts in one report per building, with the source of every value named.
How do you assess climate risk before buying a property?
Start with the building, not the region. A portfolio average or a regional map says little about the one asset that sits in a flood zone or below a steep slope. A climate risk assessment for real estate has to answer what an investment committee asks about a single address: is it exposed, to what, how strongly, and which public source says so? That is the job of a building-level physical climate risk assessment.
In Norway the underlying data is public but spread out: flood zones and landslide susceptibility maps at NVE, weather statistics at MET Norway, building records in Kartverket's Matrikkelen and zoning plans in municipal plan data via Geonorge. HOMAI collects them for the address you choose, adds an imagery-based reading of the roof and combines everything in one report with a deterministic score.
That moves physical climate risk into the screening stage of a real estate deal instead of the end of technical due diligence. No site visit is needed and each analysis runs in the background (it can take minutes per address), so a long list can be screened before money is spent on inspections.
Where does climate screening fit in an acquisition?
One way to use HOMAI between the long list and the signed deal:
Load the candidates
Search an address, click the map or draw an area; an administrator can import a CSV list.
Run the analysis
Registry, terrain, planning and hazard data are added, and the roof is read from up to seven images.
Read the risk picture
Check the climate score, the four hazard bands and the roof risk index, each value with its source.
Target the inspections
Send the technical adviser to high scores and uncertain data first, not to every building.
File the evidence
Export the A4 PDF for the investment memo or the data room.
Which building-level data supports real estate due diligence?
Each HOMAI report brings the following together for one property. Official values are used as published and are never re-estimated by the AI.
| Topic | What the report shows | Source |
|---|---|---|
| Flood | Whether the building lies in a mapped flood zone (with return period) or a flood susceptibility area; banded 1 to 5 | NVE Flomsoner and Flomaktsomhet |
| Landslide | Whether the building lies in a landslide susceptibility area; banded 1 to 5 | NVE aktsomhetskart |
| Heavy precipitation | Daily maximum and heavy-rain days over ten years at the nearest weather station; banded 1 to 5 | MET Norway, Frost API |
| Storm | Wind gust statistics at the nearest weather station; banded 1 to 5 | MET Norway, Frost API |
| Roof | Roof type, pitch, material, condition, visible defects, penetrations and drainage, which feed the 10 roof risk factors together with the build year | Aerial, satellite, street-level and LiDAR imagery; Kartverket |
| Building | Build year (byggeår), usable floor area (BRA), floors, building type, gnr/bnr and plot boundary | Kartverket, Matrikkelen |
| Terrain | Ground and surface elevation, building height, slope and aspect | Kartverket national height model (LiDAR) |
| Planning | Zoning plan (reguleringsplan), hazard zones and consideration zones | Municipal plan data via Geonorge |
| Heritage | A flag for buildings in the SEFRAK register | SEFRAK (Riksantikvaren), via Geonorge |
The roof section describes only what is visible in the imagery. HOMAI does not guess roof age from pictures: the building's official build year from Matrikkelen serves as the age proxy, and a separate factor looks for visible change in historical orthophotos without dating the roof. If you want to go deeper into the roof condition before an acquisition, the roof analysis page lists every factor and its default weight. The report also carries an insurance classification with recommendations, useful when insurability is part of the investment case.
How does HOMAI support EU Taxonomy and ESG reporting?
ESG reporting on physical risk in real estate and an EU Taxonomy assessment both need to show which buildings are exposed to physical climate hazards. HOMAI supplies the building-level evidence for today's hazard picture: the four exposures above, their bands, the source behind each value and a deterministic score that gives the same result from the same inputs.
HOMAI's hazard data is NVE's current mapped zones and ten years of observed MET Norway station statistics: a picture of today and the recent past, not a projection of future climate. A full climate risk and vulnerability assessment under the Taxonomy also looks ahead, so that part has to come from elsewhere. Use HOMAI as the screening layer that shows which buildings deserve the deeper analysis.
HOMAI covers physical risk only. Transition risk, the risk that comes from policy, technology and market changes on the way to a low-carbon economy, is outside its scope.
How do you compare assets across a portfolio?
Every analysed property appears as a pin on the map. From there you can compare assets across your portfolio: the portfolio view summarises the latest analyses by risk band, lists the highest-scoring properties and keeps the analysis history of each one. The bands for the overall property score are:
- Low: below 40
- Medium: 40 to 69
- High: 70 or above
By default the overall score weights the climate score at 0.6 and the roof risk index at 0.4. The weights are configurable per deployment, and the report's methodology section prints the formula with the property's own numbers.
The view reflects the latest analysis of each property. Re-run an analysis when you need a fresh picture, for example before a refinancing or a sale.
Which data sources and method can you cite in a report?
Numbers in an investment memo have to survive questions from a committee, a lender or an auditor. Three properties of HOMAI help:
- The AI never sets the score. A multimodal AI model describes what is visible on the roof; the score is plain arithmetic over weighted factors. The same property, imagery and weights always give the same result.
- Every value carries its provenance. Values are labelled official, calculated, AI-estimated, AI-inferred or estimated, with the provider, a confidence between 0 and 1 and a short basis.
- Gaps stay visible. Missing data shows as "Not assessed" or "Not derivable" instead of a filled-in guess.
The public sources are cited in the report and can be checked directly: Kartverket's property data, NVE for flood and landslide mapping, and MET Norway's Frost API for weather statistics. The full list and the formula are on the page about the data sources and method you can cite.
What does HOMAI not do for investors?
- It does not replace technical due diligence, a physical inspection or a condition report (tilstandsrapport). It is remote screening.
- It does not put a money value on risk: the report has no property-value, loss or repair-cost estimates.
- Its hazard data describes today's mapped zones and the past ten years of weather statistics, not future climate scenarios.
- It covers Norwegian addresses only.
- It does not monitor buildings continuously or send alerts.
If the assets are financed, the lender can work from the same building data for its collateral: see HOMAI for banks and lenders, or the overview of all four industries HOMAI is built for.

Frequently asked questions
- Does HOMAI cover properties outside Norway?
No. HOMAI is built on Norwegian sources: Kartverket's Matrikkelen and national height model, NVE hazard maps, MET Norway weather statistics, NIBIO land cover data and municipal plan data via Geonorge. Any Norwegian address can be analysed. For buildings in other countries there is no equivalent data in the product today, so foreign holdings in a portfolio need another source.
- Can HOMAI replace technical due diligence?
No. HOMAI is remote screening from imagery and public registers, and it does not replace a physical inspection or a condition report. Its job in a deal is to show early which buildings carry flood, landslide, precipitation, storm or roof risk, and where the data is uncertain, so the technical adviser's time goes to the properties that need it.
- Is a HOMAI report enough for an EU Taxonomy climate risk assessment?
Not on its own. HOMAI gives a documented, building-level picture of current physical hazards, with cited sources and a reproducible score, which is a useful input. Its data describes today's mapped zones and ten years of weather history rather than future climate scenarios, so the forward-looking part of a climate risk and vulnerability assessment has to come from elsewhere.
- Does HOMAI estimate how climate risk affects property value?
No. The report expresses risk as scores and bands, not money. It contains no property-value, loss or repair-cost estimates, so it does not tell you how much a flood zone or an ageing roof should move the price. It gives you the exposure facts and their sources; pricing that exposure stays with your valuation team.
