Parametric Shading System

As part of the design of a dormatory project, each dorm unit was designed with floor-to-ceiling glass to maximize sunlight and views. To help control the amount of light entering each room, a facade system was designed through the use of parametric modeling. Given the nature of the overall building, a bent bar, the system only had to compensate for two major sides of the building, one facing facing south-east and the other facing north-west. Developed in Grasshopper, the skin takes into consideration an average arc of the sun throughout the year, specific to the site. Each glass element is rotated during installation to allow for light to bounce onto the soft reflective ceiling of each unit while reflecting some light away from the building.


The system is made up of four pieces, five bolts, two rubber seals, and a piece of glass. The circular disk in the center is punctured with holes every 15 degrees, which control the rotation of the glass.
