A side counts if it has 5 or more measured buildings; if neither does, the whole street is shown. Streets with 15 or more buildings have their own page, with the three floors of each side.

What we measure
The report's winter scale, from “No winter sun” to “Lots of winter sun”, based on direct sun on the window on 21 December, 1 m from the façade at window-centre height. It comes from the ICGC's 1 m LiDAR (2021–2023 flight) and the sun's position, minute by minute.
Here the figure is the scale for each side of the street and each floor, the median of its buildings, not of one flat. The exact minute count for a specific flat, with its window, its floor and whether it faces the street or the courtyard, is the report.
With 1 m LiDAR, narrow streets and eaves come out less sharply than with Barcelona's 25 cm data: the average error is around 15 minutes a day. Tree canopies let part of the sun through, and buildings put up after the 2021–2023 flight are not included.
Sun Seeker, ShadeMap, SunCalc and Asoleo: what each one measures
Your flat, with its window and its floor
This page is about the street. Your window may face a courtyard, a chamfered corner or a building that does not weigh in here. The €19 report measures yours, minute by minute, all year.
