The exact specification for shading devices can be done after the building #1 design. - You are located at approximately 45 degrees N latitude in Milan, Italy. - You have a southern-facing window that is 3’ wide and 8’ tall. - Reference the sun charts for Milan, Italy included in this exercise.

Overhang Width: ________________ 5 Overhang Depth: ________________ Height of Shading Device Above Window: ________________ Horizontal Offset of Shading Device: ________________
