I created a curved wall surface starting from an arc, which I then extruded vertically to a parametrically controlled height. I subdivided this surface into a grid of panels using the Quad Panels component, and used the centroids of each panel to obtain coordinates on the surface. These coordinates were then used to sample colour data from an input image (the visible light spectrum), which I mapped onto the façade panels.
The geometry and appearance are controlled through several parameters. I can adjust the curvature of the wall by changing the arc radius and angle, and control the overall height of the surface. The panel density is also controllable. A scaling factor allows for the control of the spacing and porosity of the façade.
I generated a serpentine wall by starting from a line and deforming it using a sine function, which allows for the control of the amplitude and number of waves parametrically. This curve is extruded vertically to create a surface, which I subdivided into panels using the Quad Panels component. I used the centroids of each panel to obtain coordinates on the surface, and sampled colour data from an input image. Instead of applying the colours directly, I extracted brightness values from the sampled colours and remapped them to a range of extrusion distances. These distances are then used to offset each panel.
The system is controlled through several parameters. I can adjust the wall length, amplitude, and number of waves to control the form and also the height of the extrusion. Panel size is also parametrically defined.
I created a two-level building mass from a parametrically controlled rectangle. I can adjust the length, depth, height of each level, and the offset of the upper floor. I extracted the façade surfaces and panelised them into vertical elements, then generated shutters from each panel. I used the direct sun hours component to determine how much direct sunlight the shutters received throughout the year. These values are then mapped onto the geometry by changing the shutters’ colour according to how much sunlight they receive.
The lower level length, depth and height are modifiable, as well as the upper level height and footprint offset. Moreover, the analysis period can be adjusted to parts of the year by changing the starting and ending month, day, and year. Changing the sutter opening angle, one can evaluate how much direct sunlight the shutters receive across the analysis period.

The two-level building mass from a parametrically controlled rectangle, from before, is used to open/close shutters reacting to how much direct sunlight they receive. The sun vector and the panel normals are used to calculate the dot product, which represents how directly the sun hits each façade. These values are remapped to control the shutter opening angle, so that when the sun is more perpendicular to the façade, the shutters close, and when the sun moves away, they open. This creates a responsive shading system that adapts in real-time to solar position.
I can modify the building proportions (length, depth, height, and upper level offset), as well as the panel density. The system allows control over the date and time, which directly influences the sun's position. The shutter’s opening limits can be modified to control how aggressively the façade responds to solar exposure.
