A neighbourhood (Grätzl) in Vienna's 22nd district. Strongest on Green space and Safety, while Quiet is more of a trade-off.
New, modern buildings stand around the lake — a district that is only just taking shape. Water and greenery are right outside the door, and daily life stays relaxed. In the evening a calm settles over the water, giving the place its own mood.
The six dimensions
Light & built form
Asperner See is low and openly built — plenty of free sky above the rooftops. No measured sun hours exist for this Grätzl — the classification follows the real building heights (zoning class & OSM). A single flat depends on floor and orientation.

The roofs above Asperner See
Within 450 m of the centre, buildings carry around 4 hectares of roof that would be greenable by pitch — 38.5 % of the roof area there, calculated from the City of Vienna’s official roof model. On that area roughly 8,400 m³ of rain a year would stay up top instead of entering the sewer, by the model. The modelled heat index here is 40 out of 100.
The radius is a fixed reference area, not a neighbourhood boundary, and the circles of adjacent neighbourhoods overlap — so these figures cannot be added up. Whether any of these roofs is already green is unknown to a geometry model; whether it carries the build-up is for a structural engineer to say. Geometry as of 2016. All districts compared →

Where is Asperner See?
Asperner See is in Vienna's 22nd district (Donaustadt), postal code 1220.
How safe is Asperner See?
Safety in Asperner See: Excellent (9.0/10), based on official police crime statistics. A non-binding orientation value for the area, not a statement about any single address.
Is Asperner See dangerous?
Short answer: no — Vienna consistently ranks among the safest large cities in the world, and that holds across all 23 districts. Asperner See sits at 9.0 out of 10 on the safety dimension (Excellent). One thing worth knowing when reading such figures: crime statistics count offences where they HAPPEN, not where those affected live. Districts with major stations, nightlife and many visitors therefore collect more reports without a residential street a few corners away being any different. Within a district, the gap between a busy hub and a quiet side street is usually larger than the gap between two districts.
How good is public transport in Asperner See?
Public transport in Asperner See: Excellent (8.8/10) – based on proximity to metro, tram and bus (Wiener Linien).
Is Asperner See noisy?
Quiet in Asperner See: Excellent (8.3/10), based on traffic-noise exposure. The noise sits at the edge along Eßlinger Hauptstraße — away from it you notice little. Right there you raise your voice to talk, and a phone call on the pavement gets tiring (calculated above 70 dB by day). At night it calms down noticeably — the level drops below the threshold at which mapping begins. The busiest named axes nearby, by official annual traffic volume: Eßlinger Hauptstraße (~20,224/day), Groß-Enzersdorfer Straße (~19,317/day).
How hot does Asperner See get in summer?
In summer Asperner See is cool — cooler than the Vienna average. Heat index 40 of 100 (Vienna average 57), modelled. Green cover, trees and open, low building form let the night cool down. This is a MODELLED index (from building form, density, green space, street trees, water and elevation, checked against the City of Vienna's climate analysis map), not a measured temperature and not a count of hot days. Within one area it varies a lot: a green courtyard and a treeless street a few metres apart are not the same place.

Green space in Asperner See: Excellent (9.8/10). Parks and greenery shape everyday life here.
Who is Asperner See a good fit for?

It says nothing about which of those roofs is already green, and nothing about statics.
