A4 phase 3 - Perceptual apparatus / Window expander

Obstacles and sun light.

Investigations of inflow of sunlight.

Diagrammatic drawing of obstacles and position of the sun.
The position and angle of the sun is costantly changing. On this diagram,
 three specific positions are highlighted; summer solstice (when sun is highest), equinox,
and winter solstice (when sun is lowest).
The apartment is located on 4th floor and due to the landscape (24 meters above sea level)
 with a quick decrease in hight towards East, the only direct obstacle for optimal inflow of sunlight
 is the apartment it self and the building right next to.
Southeast of the window, the area is almost free of essential obstacles, and inflow of light
 is almost unbothered.
