Pilot · every score done by a person
Light that reaches the back of the room. Ceilings you notice. We measure how a home will feel to live in, from its floor plan, before you buy it.
The problem
A listing shows the price, the square metres and the energy class. So that is what new buildings are designed to hit.
Big windows make a good energy class harder to reach. Small ones make it easy. A flat can be rated A+ and still feel like a box.
Buyers cannot ask for light, tall ceilings or solid walls, because no listing measures them. Airloom does.

Take the numbers from the floor plan. This is a quick check of one room, not the full Airloom Index.

Same thresholds as the Airloom method: window area, window height, room depth, ceiling, orientation.
No adjectives. Every point in a score traces back to a measurement and where it came from.
Built on the European daylight standard, EN 17037, and the national building rules, not on taste. The method is public, so anyone can check a score.
The lot across the street is empty today, so the flat is sunny today. The zoning plan says how tall it may be built. We read it, and tell you how much sky you could lose.
Vienna first. Italy and Portugal next.
Most buyers see a house as it is. Airloom Potential shows the score it could reach, and the moves that get it there.
Illustration. Whether a wall carries load cannot be known from a plan alone: every "probably" is confirmed by a structural engineer before anyone picks up a hammer.
Selling a house with small windows? Show buyers what it could become.
Near Lisbon, a duplex with a double-height living room, a wall of glass, a garden in the middle and a shop downstairs is listed at €4 million. The things that make it lovable cost a fraction of that.
A few households, each putting in what a good flat costs anyway, can commission a building like that. No developer between you and tall windows. Neighbours you chose.

One-off, before you buy

Every room measured from the plan, what may be built opposite, sun through the year, and the questions to ask the seller.
A building surveyor’s visit before purchase usually costs €1,000 or more, and checks for defects, not for light.

Today’s score and the score the home could reach: walls that could probably go, openings that could grow, and a rough cost for each move.
For a €500,000 house, less than 0.1 % of the price. A structural engineer confirms every "probably" before any work.

The plan, the page, the date. Where a developer publishes nothing, we say so.
Published before the first named score, so anyone can redo the sums.
