Factor values are objective. The lens "General" only weights them — Ubivo doesn't judge the address. Persona presets are the MVP form; per-account profiles follow.

Calculation level: terrain + buildings. Reference day: climatological standard day (equinox), so the score is independent of the query date. The score shows the share of daylight that arrives unshaded despite terrain and buildings. Building heights = OSM heuristic; swissBUILDINGS3D precision + per-floor personalisation + vegetation = inherited follow-up layers. A missing source lowers reliability, never guessed. The building itself (geocoder point within the footprint) was excluded from shading — otherwise the house would shade itself all day. The same sunlight engine computes planting-site sun suitability in Arboreon.
