We will not fail to insist on the inadequacy of resorting to nearly completely glassed facades in our climate. That said, and letting ourselves be carried away by formal issues, we can only applaud the wise decision to force imperfection.
The curvature in the lower part of the cantilevered volume resolved with triangular glass planes, with difficult encounters between them, and with the vertical façade planes.

Again a nearly completely glazed façade facing northwest.

The purpose of this decision can be clearly understood when you get inside one of the classrooms behind the façade. Even the shallowness of the plot, inside the classroom you fill the space is wider. Aragon Street is a background space added to the room. 66.1 AC/16/88.1 AC glasses try to avoid excessive noise. Thermal loses are again the weak point. 

This is a unitized façade system, which means a completely prefabricated curtain wall solution. A panel is used with all the onsite mounting benefits that panels can have. What is more it is light, so big components can be used that are perhaps two stories high. During preassembly, all the façade layers can be incorporated into the same frame, and thus into a single panel. The glass does not need to be related to transparency; it can simply cover the blind area of the façade to provide a continuous image from the outside, as we normally do with the slab edge front.

Composite façade panels are nothing new. They are there, waiting for the moment when the market will be ready to welcome them since the last decades of XX century.

The technology is already developed and essayed as those materials are perfectly used in many other applications. Maybe the cost, maybe the origin of the material (glass-fiber reinforced polyester), maybe we have not found yet its advantatges in building construction.

Load bearing facades are nowadays a common solution due to the permeability they permit in the inner space. Some of those structures are let to be seen from the outside, some of them are not. 
It is not that common resolving this load bearing façade subdividing it into two structures placed side by side; one inside the water, air, and thermal barrier of the enclosure, while the other outside it; one clearly supporting the slabs loads, while the other drawing some kind of stabilizing diagonals. A vertical configuration versus an arborescent outside image. 

This is another classic that should not be missed. It is unquestionably impeccable. Let us simply highlight the potential of resorting to a simple curtain wall with a few crucial variations: the exceptional glass with its curvature, texture and roughness; its format and size; and the lack of collinearity between mullions and transoms, enhancing horizontality. All of these factors contribute to accompanying the gesture of both volumes towards the sea. The position of the two blocks, the volumetry and the façade definition all talk the same language.

It is surprising how this facade makes a virtue of the sometimes uncomfortable transparency of the glass.
The succession of staggered and slightly overlapped planes that, either reflect the neighboring facades, or exhibit the daily life of the interior space, combined with opaque surfaces placed in different planes and rolling interior sunscreens, manages to create an abstract order that gives coherence to the whole.

Ikea who? (C.006)

This façade's goal is not to create a traditional static architectural image for the city, but to design a technological solution that responds to the inhabitant's complexity through their life course there.Therefore, we have developed prefabricated façade-ceiling-roof components, gathered in a catalogue.

Unitized panels with enhanced thermal and acoustic performance (C.001)

PROJECT'S CONTEXT This project tries to rethink the role of the Gran Via and the relationship between the different urban areas approaching El Prat to l'Hospitalet. A series of structural modules are proposed as a base to which trusses can be added.The module could be implemented in other places as a roof that’s able to collect water and produce energy. Responding to the changing needs of the infrastructure, the new building, which is going to host the new Technology Park, is a flexible space where the facilities and construction solutions are based on the Plug&Play system.

Awarded the Pritzker in architecture, the value of this work is undeniable from a formal perspective. However, doubts arise when we consider the functional aspects of thermal and lighting comfort in a Mediterranean climate at 41 degrees latitude.
