Project V2.
Project V1. has a well-defined shifting pattern based on the orientation of the building and the sun angles. In project V2, I will redesign the non-panoramic façade, which has irregular shapes, to a regular profile that follows the building mass lines. The new curtain wall design will alter the depth parameter in one-panel type to create a unique sun responsive panel (figure17.). To develop more visibility and versatility in the façade, three types of curtain wall panels have been used in a random pattern (figure17.). However, the complete glass panels account for just 25% of the curtain wall, reducing the likelihood of direct sunlight accessing the interior rooms. The other panels mostly shade the fully transparent panels. The extruded box panels make up half of the curtain wall, while solid panels make up the other quarter.

1.1. Custom curtain wall panel
The strategy to achieve the described
pattern that I have implemented in my project is creating a custom curtain wall
panel family (figure 18.). The method will follow the hosted curtain wall
pattern, which will generate an entire parametric wall to control the panel in
the project and dynamo view. The desired controlled parameters must be created
in the family view and passed to the project (figure 18.).

1.1. Applying Dynamo
The dynamo software can extract the Revit metadata and change or modify any Revit data structure and organization parameters. This feature has the power to implement the unlimited possibility of custom data structure and mathematical equations. In this project, the custom curtain wall panel and the hosted wall have been extracted and modified. Figure 19. shows the dynamo workflow in this project.

Customizing the custom curtain
wall panel
As described above, one of the new
features of the proposed design is randomizing the depth of the frame to create
protection from the direct solar radiation and a more dynamic harmonic façade
that match the building mass. The depth of the frame has been altered by dynamo
script with the range of the foot to five feet depth, and then the depth
randomization has implemented in that range, creating a unique depth for each
panel (figure 20.). A separate dynamo script has determined the panel frame
width to increase the parametric project flexibility (figure 20.). If we would
customize the frame width of the panel by randomizing or responding to the
solar radiation, the parameter will be exposed and extracted in dynamo.

Customizing the hosted curtain
wall type
I have extracted all instances of
the hosted wall in the project. Then, I introduced three types of curtain
panels to the wall by different weights (figure 21.). The first is the custom
panel, which has the highest importance, 50% of the total panels, the second is
the fully glazed panel with 25% of the total, and the third is the opaque panel
with 25% of the whole. A list cycle node is circulating and mixing the three
types of panels to ensure the hosted wall instances do not get one kind of
panel. The hosted wall properties control the number and size of the three
types of panels (figure 22.).

Window to wall ratio
After the implementation and
customization, we must have a determining factor that helps the decision-making
for one pattern and panels percentage over the other. I went with window to
wall ratio for only the custom curtain wall type. The custom curtain wall panel
opening to opaque ratio has been calculated separately by subtracting the panel
frame from the total panel area (figure 23.). The full glazed panel has the
whole area as an opening, and the opaque panel has zero opening area (figure
24.). The weighted average has been used to account for each type of panel
(Figure 24.).
