Metal profiles assembly

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.

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.

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. 

Inverse Unitized (C.005)

The modular and low density character of the mat building typology in which the project is based gives as a result a large number of façades, but of similar characteristics. Due to this premise, it was chosen an unitized panel system of double height that respond to the big and regular dimensions of the building, with the aim of systematizing its construction.

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.

There is little to say here, it is just a masterpiece!

Jean Prouvé was probably the first architect working as a façade specialist.

He was probably the first to opt firmly for façade prefabrication.

This façade is not watertight and it is not airtight. Depending on the density and size of the stones, it protects against direct sun radiation but without managing the visual relationship with the outside. It considerably blocks the entry of light, gives privacy and protects from intrusion. If it is true that, together with a drained cavity, it would constitute a watertight envelope, but it seems that this is not the case here.

Energy-efficient architecture does not have to have a certain image. This is clear in the work of Sauerbruch & Hutton, which has a sober but colourful image.

This is an interesting resource to hide the blind area associated with the edge of the slab, the facilities’ cavity and the elevated floor without having to delimit this area with two transoms visible in the elevation. The only apparent cutting is that of the unitized panel, with greater or lesser density in the pattern of the serigraphy that opalizes or simply veils the transparency of the glass.

This use of the double skin facade where the outer glass is patterned with a white serigraphy that gradually dilutes as one gets closer to the areas of vision may disappear as rapidly as it has spread. It is an easy way to blur the openings limits. In the case of this hotel in London, the opening is perfectly well defined on the wall in the interior skin. This technique harks back to the effect of traditional interior thin white curtains, except for the important difference that the curtain can be used to cover the openings with a very efficient light diffuser.
