I am working in a circular building, with the following dimensions:
– height – 30m (approximated, 8+1 floors)
– diameter – 48m (measured on Google Maps)
– coordinates – 50.842519, 4.385583 (retrieved via Google Maps)
I was recently wondering how many days of sunlight the inner court of the building gets every year.
