Prices include VAT; businesses enter their VAT number in the payment window (reverse charge). Sold via Paddle. Pay by card, PayPal, Apple Pay or Google Pay. Premium is an open-ended subscription, billed monthly in advance (€39 incl. VAT per billing month; a subscription taken out during the beta keeps this price for as long as it runs), cancellable at any time for the end of the current billing month. Office is the same subscription for an office — several people on one Azima key — at €249 incl. VAT per billing month. As a consumer you can withdraw within 14 days of subscribing; Paddle then refunds the first payment in full. After cancellation, billing months already paid are not refunded pro rata, unless the fault is the provider’s. Withdraw from contract · Cancel contracts here · Lost your key?

Azima calculates for any Vienna address, from the officially measured building heights, how many hours of direct sun each room gets — with your floor plan, in your browser. Looking is free. A report as a PDF costs €9.50 once, Premium for agents and developers €39 a month, VAT included.
What Azima does differently
Azima is the only one that turns your floor plan into a 3D room and runs it against the city’s official data — no scan, no appointment, in your browser.
Copy the floor plan from the listing, and Azima reads rooms and windows. Hours of sun per floor are also free in Vienna — on willhaben listings and in wohnwahn’s sun check. Neither of them reads your floor plan.
Eaves and ridge from the official Vienna roof model. A south window with a 22-metre facade opposite is not a south window.
Hours of direct sun for the kitchen, living room and bedroom on three reference days — not one number for the whole house.
The floor opened from above, the sun on the floor, at any minute of the year. Not the shadow on the street.
What the report contains
The listing says “bright”. The report says when the sun reaches which room: on three reference days, hour by hour, with the gaps the neighbouring houses cut into the day. Calculated from the window direction, the officially measured heights opposite and the path of the sun.
Zoning, listed buildings, land register parcel, environmental noise, flood, heavy rain, torrents, terrain, contaminated sites, radon, earthquakes, geology, broadband — plus from Vienna Living Map the summer heat (modelled, not a measured temperature), markets, street trees and aircraft noise from its own measurement series. Regardless of who offers the flat.
A 3D sun calculator shows where the shadow falls on the street. Azima opens the house: the floor from above, the rooms from your floor plan, the sun load as colour on the floor. For any Vienna address — without your own floor plan with an example that is expressly marked as an assumption.
Everything that is in it
The whole scope in three groups — every line with what it costs. The city and the tools are free; only the report is paid, with Premium without limit.

Why the price is what it is
Azima does not replace an expert opinion; it answers the question before it — is the viewing worth it, does “bright” hold in December too. For that, €9.50 is about a twentieth of one expert hour.
5 single reports cost €47.50, Premium costs €39 and has no limit. Anyone offering more than 4 properties a month pays less with Premium. OpenImmo enrichment, the partner link and your own sender are free for everyone anyway.
On the sale of a €400,000 flat the agent’s commission is capped at 3 % per party under Austria’s estate-agent regulation, that is €12,000 plus 20 % VAT. Premium is 0.3 % of that — for a whole month and every property. An exposé that answers the question about light before the prospect asks it does not have to move much to pay for that.
Azima and Shadowmap
Shadowmap is the best-known 3D tool for sun and shade — worldwide, with a free camera, and in its Home plan with high-quality buildings for Vienna too. The table sets side by side what Shadowmap’s pricing page lists and what Azima does. Bold marks whoever leads in a row — including where that is Shadowmap.
“—” means: not listed on Shadowmap’s pricing page. Source: shadowmap.org/pricing, retrieved 26 Sep 2026 (Home $8.33 a month billed annually, $10 monthly; Studio $50 or $60). Sun position and trackers: from the public app code at app.shadowmap.org, read on 18 Oct 2026.
How you get Premium
Open Azima, enter the address, paste the floor plan from the listing — the light check is free.
On the Premium page: “Subscribe to Premium” opens Paddle’s payment window — with your VAT ID for reverse charge. No account, no password.
From then on every report carries a verification link. Your Azima key is the login on any device; invoices, payment method and cancellation live on the Premium page, one click into Paddle’s customer portal.
Honest, even when it hurts
A measured disadvantage is never removed, only explained better. Aircraft noise, shading, summer heat stay in the report — at every price, Premium included. That is exactly why a flat hunter believes the sheet — even when the seller paid for it.
Open Azima — free →Frequently asked
What does Azima cost?
The light check is free: address, house, path of the sun, dollhouse, shareable link. A report as a PDF costs €9.50 once; Premium for agents and developers costs €39 a month and includes reports without a limit. Prices include VAT.
Who is Premium for?
For anyone offering more than 4 properties a month: agencies, developers with a project on the market, property managers with vacancies. Premium includes reports without a limit. The tools — OpenImmo enrichment, partner link, widget, your own sender — are free for everyone; you only pay for the reports, with Premium without a limit. A single sale does not need Premium — that is what the single report is for.
How do I subscribe to Premium?
On the Premium page (viennalivingmap.com/en/premium/): “Subscribe to Premium” opens Paddle’s payment window. No account needed — after buying, Azima shows your Azima key, twelve characters, your login on any device. The invoice comes from Paddle by e-mail; your subscription, invoices and cancellation are on the same page.
Do I need an account?
No. The light check runs without an account, and a purchase does not create one either: Paddle only remembers a random Azima key that your browser generated. You see this key in Azima after buying — with it you bring the purchase to another device.
Can I try Premium before paying?
The light check stays free, and with the example floor plan the PDF costs nothing — so you see exactly what a report contains. Free preview: every page, hours for one room on one day. Premium has no trial; as a consumer you can withdraw within 14 days of subscribing, the subscription then ends immediately and the first payment is refunded in full.
Is the report an expert opinion?
No. Azima is software that calculates a model from open data: measured neighbouring heights, the astronomical path of the sun and the floor plan. Curtains, balconies and trees are not part of the sun calculation. A certificate of insolation under ÖNORM is a different, signed document by an expert.
Why is €9.50 a fair price?
An hour of a building expert in Vienna costs between €185 and €250 plus VAT according to published price lists. Azima does not replace an expert opinion — it answers the question before it: is the viewing worth it, does “bright” in the listing hold for December? For that one answer, €9.50 is about a twentieth of one expert hour.
When is Premium worth it?
From report no. 5 in a month: 5 single reports cost €47.50, Premium costs €39 and has no limit. Measured against one sale it is small: an agent’s commission is capped at 3 % per party under Austria’s estate-agent regulation — €12,000 plus 20 % VAT on a €400,000 flat; Premium is 0.3 % of that, for a whole month and every property.
How does Azima differ from Shadowmap?
Shadowmap shows sun and shadow on 3D buildings worldwide, with a free camera and your own 3D models — that is its strength. Azima reads the floor plan of the flat and calculates the hours of sun for every room, shows the flat from inside, adds information from 16 official Viennese sources and writes the report as a PDF. Azima only works in Vienna.
Who sells the report?
Paddle.com Market Ltd, London, as merchant of record: Paddle is your contractual partner for the purchase, issues the invoice and handles the tax. The payment window only loads when you click “buy”; before that there is no Paddle script and no cookie.
What is the Azima seal?
Every page of a bought report carries an identifier and a verification link. The link shows that Azima issued a paid report on the stated day for a property with this identifier. It does not check the content of the PDF: whoever receives it compares the identifier with the footer of every page. The figures remain model results from open data, not an expert opinion. For the seal only your Azima key and a checksum reach the server — address and floor are not in it in plain text, the floor plan not at all.
Can a disadvantage be removed from the report?
No. A measured disadvantage is never removed, only explained better — aircraft noise, shading, summer heat. That holds for every report and every plan, including Premium.
Can I get a refund?
Within 14 days of the purchase, by e-mail, via Paddle or with “Withdraw from contract” in the footer of every page. For a single report you request before buying that work begins straight away, and you confirm that you lose your right of withdrawal once the report has been fully created. If creating it stops before it is complete, you get the full price back. Consumers can withdraw from Premium within 14 days of subscribing. Details in the terms.
