Episode notes
City Sunspot Origin Story
- Georg Molzer noticed he couldn't see the sun for two weeks in Vienna and sketched an app idea to find sunny spots at noon.
- Seven years later he built ShadowMap after finding no satisfying solution existed.
3D Sunlight Modeling Reveals Hidden Shadows
- ShadowMap is a 3D sunlight model combining buildings, trees and terrain to simulate shadows across day and year.
- The analytics heatmap shows per-surface sun hours and reveals winter sunlight scarcity at a glance.
Check Sunlight Before Buying Property
- Use ShadowMap before buying property to check light availability across seasons and avoid winter darkness surprises.
- Limit analyses to winter months to see true low-sun exposure on facades and plan accordingly.
