🔬 Measurements
What Azima measures
What Azima works out about one address, each from open data rather than from a sales text. Every page says what is computed — and where the calculation stops.
One address, measured rather than described
☀️Sunlight hours per room: how much sun a window actually getsWhat decides the light in a room is not its compass direction but what stands opposite. Azima works the sun’s position minute by minute against the measured horizon around the building — and ends with two figures: how much sun in total, and how much of it in one unbroken stretch.🏢Shading by neighbouring buildings — the figure an orientation cannot give youAlmost every listing states an orientation. It describes a rotation, not the arrival of light. Anyone writing about sunlight in a listing should have the neighbouring buildings in the calculation — otherwise the advert makes a claim the viewing disproves.🌡Solar load per room: which room gets hot in summerSame calculation, different question. A room with too little sun in winter often has too much in summer — and on the top floor under a metal roof that is not a detail. Solar load relates the incoming sun per room to its floor area and shows which room carries the burden.✈️Aircraft noise at one address: which flight path, how often, at what hourA noise map colours areas. A flat sits at a point, and what matters there is: does the address lie within the measurement band of a flight path, how many aircraft passed in the sample, and at what time of day.🛩️Your address from above, 1938 to today: twenty aerial surveys of the City on one sliderWhat lay under your flat 70 years ago? The City of Vienna has photographed its area from the air again and again. Azima stacks those images at one address: the same spot, one slider, from 1938 to 2025.📐Reading floor plans, OpenImmo and IFC — in the browser, without uploadThree ways in, one report out. A floor plan as an image or PDF, the agent export your software already writes, or an IFC model. Reading happens on the device — there is no endpoint the file could go to.🏘What the neighbours may still build — and how much sun you would keepA flat is bought for the sun it has today. Whether it still has it in ten years is decided by the building class of the houses around it: whoever stands lower than allowed may add storeys. Azima raises every neighbouring building to the upper limit of its building class and calculates the three reference days again — today against built out.🧩Merging plots: what two parcels together would allowDevelopers in Vienna often buy the house next door as well. Azima reads the adjoining plots from the cadastre, adds up their areas and the existing buildings on them, and calculates the new building by building class — with the demolition of the neighbouring buildings in the calculation. In the browser, without an owner search.🗣Explaining drawbacks honestly: one sentence per measured drawbackAt the viewing someone asks about December. The talking points have one sentence for every measured drawback: what is measured, where it comes from — position or condition — and what it means day to day. On the page to copy, in the report as a sheet of its own.
The common tools answer the light question from a compass direction, or buy in a shadow map for the outside and leave the inside to the orientation. Both truths then sit in one document about one property. Here everything comes out of the same geometry, so the hour at the window is the hour in the room behind it.
