I created a sun analysis in FormIt; depending on the direction that the building faces, the amount of sun it receives is different. I have ran the analysis at different times of day so that you can see how the shadows change.
Sunlight and shadows at 6am
Sunlight and shadows at 11am
Sunlight and shadows at 8pm
This is the sun path of my building. As you can see the sun is hitting the glass front therefore maximising the amount of sun.
