Media Facade adapted on Piraeus Tower

Research on Media Facade constraints

It’s a thin mesh containing horizontal bars, which carry the LED s. The distance between the bars is the same as the  as between the LED s, which gives the effect of a raster.

There are some size constraints:

maximal width: 4 m

maximal height: 20 m

Which shows the following placement on Piraeus Tower:

Plan and Section of Media Facade on Piraeus Tower, combined with the window system of our greek friends:

This mesh filtrates the sunlight and allows a view outside. But the view is always a bit disturbed by the mesh, it’s transparency is 65%.

So I want to play with dilatation of the horizontal bars, containing the LED s. To create openings in the mesh. and it  might also create some interesting orientations of the projected information to certain spots on the site.

INFORMATION [all over the] TOWER vs OPENINGS

The Info Tower helps new arriving tourists and locals to find an indication to the ferry and its departure time, to get the weather of tomorrow, the local time and date, events in Piraeus and Athens… and in the same time offering some advertisement space might cover a part of the investment in the tower.

It’s the new emblem of contemporary, metropolitan Piraeus/ Athens, right at the entrance to the city and stands in a strong contrast to its omni-present classical greek architecture.

The info panels can also function as sun – and noise block. By placing them shifted over the edge of a slab, it can create some shadow and by inclining the lower panels,they can block street noise.

Design Strategy:

First extrude the panels, depending on their placement on the facade; then create ‘cuts’ because of an exceptional interior space, which needs more direct light and views; then increase some panels, which occupy a marketing strategical place on the facade. Like edges, the center at the top and the bottom…

Analyse of strategical placement on the Piraeus Tower

Grasshopper Algorhythm:

1. Panel extrusion increases throughout the height

2. Definition of 3 heights of certain importance

3. Panel extrusion increases to those heights

4. Definition of some important points for views…

5. Lower the panels within a certain distance to such a point

–> depending on the distance to this point

6. Definition of a strategic placement of the info panels

–> Increases the height of the closest panels

Rhino and Grasshopper Model

I mostly compared the z-coordinate of a point to a certain height

and then analysed the distance to the height

if the z-coordinate is lower than the height, then it should do a certain panel… and so on…

I did the openings in the same way, by analysing the distance to such a point

Last Sketch:

After this analyse of the perforation of the info panels, I think to focuss more on the placement and the importance of the info panels is more important and should define the overall image of the tower.

The perforation of those panels, because of a need of more light and direct views should be secondary.

As indicated in the lower sketch: At important areas on the tower, the panels should be larger and the distance to the neighboring panels should be larger as well, so the important panel stands out of the homogenous panel mix.

Also the lower panels should be inclined and smaller, because of legibility factors and to block noise, as mentioned above.

Process: perforated Info Tower

Strategic placements of information panels on Piraeus tower from the different points of views on the tower.

Different panels with individual functions (sun block, info panel, noise block, windows) or one multi – performance panel system…

Some research sketches:

- sequence of different functions panels

- the panels can be superimposed


1. Sun protection panels: same height and same disposition for each floor

2. Info panels: expand vertically during the height of the tower, because of visibility constraints

3. One can define important points on the facade, where bigger openings are wanted, because of an exceptional

inside space or an imposant view -> info panels lowered or maybe pixellated or shifted

4. On marketing strategically important locations on the facade like the top and the bottom of the tower, the corners…

-> the info panels expand as well




I tried to model the two first sketches in grasshopper. The expanding info panels and 3 important apertures in the facade. Next step would be to adapt the strategical areas on the facade.

There might be an easier way, than what I’m trying to do in my grasshopper file. Maybe someone could have a look….
