X3. Glass panels wrapping

If we take the Bregenz museum as a starting point to analyze opening and perforation, we realize that there are no opening except the main door, and the emergency exit.  However, the lighting system is quite interesting. Being a museum, Bregenz, has a need for diffuse, and never direct light that is why all the panels are transparent but never see-true.  There are two ways this diffuse light can get in the building.  For the main spaces, the stairs and hallways it’s lateral, however in the exhibition rooms the light would come from above, also crossing two layers of glass.

In the Piraeus project, I took over the idea of these overlapping panels. On bregenz the main line is horizontal, but we could also imagine in vertical for a taller building, or to create more dynamic, panels could shift both vertically and horizontally.

The then density of those panels could change, and this would at the same time change its 3 dimensional form. But this seems to be too chaotic.

The idea would be to create a dynamic of the façade, in both directions, horizontally by over lapping the panels, and vertically by making the void between the structure and the actual façade alternate.

Also, it should be playing with the sunlight and the water reflects. So in this perspective I made it simpler, and playing more on the over-lapping than the density, and imagining a vertical movement of the whole.

The façade of the building is a freestanding structure. It is somehow hung from above and is punctually attached to the concrete structure to assure stability for the lateral movement and the wind loads.

All the structure is made of two “types” of cables, first there are some bigger and longer ones that crisscross over the entire high of the building and are 6 panels wide, then every panel is perpendicularly surrounded by 2 sets of crisscrossing cables, all cables seem to work in tension. The glass panels are fixed to some brackets, two at the top and two at the bottom, those are visible from the outside, and sideways, the panels are over lapping each other.

The façade has 3 main layers, the exterior plan that is created by glass panels, then a void of 90cm, where we can see the crisscrossing cables that support the structure, and finally, an interior glass panel that seems to have different proportions then the outside ones, since they go from floor to sealing.

In relation to the Piraeus project, for me what is interesting, and what should be brought to my project is this simplicity created by regular glass panels.

However, I want to create movement on this façade, as well as the impression of tallness, we could almost call it an optical illusion. To do so, these horizontal rows of glass panels should be able to slightly shift sideways, so on the high of the hole building we could eventually have them rapping around as a spiral would do.

For the grasshopper code, I made two sample floors, with two different versions, first where we have glass panels overlapping, but didn’t manage to make the separate, and then another version, that works slightly better to show the shifting on every floor.

This buiding by Zumthor is characterized by something we could call “double casing”. It’s a free standing concrete building covered by a self supporting façade completely independent from the actual building.

The facades organization is based on one very strict rule that could be defined by regularity; the rhythm is clear and constant, both horizontally and vertically.

It’s a steel structure that creates a frame which supports both the outside glass  panels overlapping, as well as the inside glass work.

The thing that makes this extremely simple façade interesting is its transparency. In between the façade and the inside there is a 90 centimeters wide gap, it’s a light pit.  The transparency allows the inside concrete structure to be visible from the outside and this “gap” in between the façade and the structure, makes this structure more or less visible depending on the light.

As a parametric formation I first started by defining 4 point from which I created a surface. The high and width are adjustable.

Then I divided the surface by row and colones, their number is also adjustable.

Besides, I waned to create a grid with horizontal and vertical lines that would illustrate the very simple pattern organizing the façade, however I did not success in doing so, since I didn’t manage to create the horizontal links.
