shadow study, sheet 01
How much sunlight reaches each roof plane, and when buildings take it. It does not estimate electricity: nobody publishes per-roof generation for Zagreb, so there is nothing to check such a figure against.
Nine drawings of the same blocks of central Zagreb, seen from the south-west: three times of day across and three dates down. Each label below gives the date, the time and where the sun is. Select a roof in a drawing, or use the buttons under the drawings.
Select any roof in the drawing above.
Day of year across, Zagreb clock hour up.
