Warehouse and hall thermal survey
Dock doors, sectional doors, ridge, panel joints, wet roof insulation, column bases: where the hall heats the outdoors.
3D heat map
Thermal images on a 3D model of your building
A thermal image is a snapshot. A 3D heat map registers many of them on one model, so you see exactly where and how large each loss is, and managers, maintenance and contractors can look at the same thing.
Illustrative example – not real measurement data.
01 / What it is
Location, size and order of every defect on one model
The 3D heat map is part of the 3D package: the heat map and the engineering analysis are made together.
In a conventional thermal report, defects are “on the left side of the north wall”. On the 3D model every defect has a defined place on the building, with its images, measured dimensions and estimated loss. You gain four things:
- Location: it is clear where the defect is; the contractor does not have to search.
- Sizing: areas (m²) and lengths (m) are read off the model; they are the inputs of the loss calculation.
- A shared view: management, maintenance and the contractor all see the same thing through one link.
- Before and after: after repairs we can re-measure on the same model so you see what changed.
The numbers on the model come from the analysis: heat loss analysis in forints. For halls, see typical findings on the warehouse and hall survey page.
02 / How it is made
From images to the browser model
Four steps, two of which we check by hand because automation is not infallible.
- 01
Thermal and visual images
Every thermal shot gets a visible-light photo from the same viewpoint and a record of the conditions.
- 02
Registration on the model
Using shared features (corners, openings, edges) we place the images on the 3D model and check them by hand.
- 03
Thermally textured 3D model
Temperature data lands on the model surface; each finding is tied to a specific point on the model.
- 04
Browser viewer
One link, nothing to install: rotate, zoom, finding cards, layers on and off.
Registration is the heart of it. We build the model’s geometry from photogrammetry and on-site dimensions. Each thermal image is placed on it using shared features (corners, openings, edges), helped by the visual-light twin photos. Where an image and the model do not agree we say so in the report instead of smoothing it over.
Temperature is the surface temperature valid under the conditions of that shot. It depends on emissivity and reflections, so we record the conditions with each image.
03 / The viewer
How to use the browser heat map
One link, a modern browser, nothing to install. It opens on a phone too, but a larger screen is better for detailed work.
- Rotate and zoom: drag to rotate, scroll or pinch to zoom; arrow keys work too.
- Finding card: click a marker to open the card: location, thermal and visual image pair, likely cause, estimated loss (W, kWh, forints with a range), fix suggestion with indicative cost, A/B/C priority.
- Layers: switch between the thermal texture and the visible surface.
- Filter: show only the “A” items, or only one part of the building (roof, south wall, dock side).
- Temperature scale: every view has one; colours are relative to the scale set per image, not absolute figures.
The viewer on the right shows an illustrative model (a fictional hall), not a real client’s data.

05 / Honestly
A decision aid, not a geodetic survey
The 3D heat map is good for deciding what to fix. Please do not use it for anything else.
- Geometry comes from photogrammetry and measurements; its accuracy is not geodetic and the model does not replace a measured survey or a BIM model.
- For ordering materials, structural or permit work, check dimensions on site.
- A thermal image shows surface temperature: it does not see through cladding and does not reveal everything inside a structure.
- Forint values are estimates with ranges and assumptions; savings only occur once repairs are done.
06 / FAQ
What people ask about the 3D heat map
In what format do I receive the 3D heat map?
You get a link that opens in a modern browser; nothing needs installing. The PDF report contains views taken from the model, and the action list comes separately as XLSX or PDF. We also hand over the raw thermal images (radiometric files). Exporting the model (for other software) is agreed separately.
How accurate is the model?
Accurate enough to support decisions, not a geodetic survey. The geometry is built from photogrammetry and on-site dimensions; we use the location and extent of defects (m², metres) to compute the loss. For construction work or ordering materials, check dimensions on site.
Can I share it with a contractor or the maintenance team?
Yes, the link can be shared. If interior shots reveal trade secrets (production line, stock) we mask them on request; how access is controlled is agreed in the quote.
When is the 2D quick diagnostic enough instead of 3D?
If the question is one door, one roof or a few known spots, the 2D quick diagnostic from HUF 190,000 also gives the loss list in forints. 3D adds value when the whole building matters, several people decide, or you want to re-measure on the same model after repairs. Upgrading from 2D within 30 days costs HUF 200,000.
