Complex profiles

Very interesting process of replacing a stick curtain wall by another keeping the building in use and without the need of building a provisional enclosure a few meters from the façade. Users do not lose the relation with the outside through the façade during the time the works are taking place.

Images speak for themselves.

In filt3rs we talk about “A unique wrapping”, P. Garrido and J. Prous in “Deep Skin” refer to “Burqas and veilings”. In any case, this project from IDOM is also subjected to this tendency to cover the building with a continuous skin, more or less abstract, placed over a more functional enclosure.

In this occasion the interior is glass and the outer skin a perforated metal sheet that reproduces the image of a green landscape.

Very suggestive sun protection mechanism.

A design that in a frontal vision would seem to be a simple formalism, takes on interest as it grows inward like vertical slats. Including those slats into a partially perforated plane with an abstract composition permits escaping from the conventional slats image.

In this orientation, northwest, the system perfectly obstructs the solar radiation of the last hours in summer days without limiting the visuals to the street or the light entrance.

Beyond the indisputable formal possibilities of a double skin glass facade: blurring the structural and / or functional order, giving uniformity,  vanishing the volume limits melting them with the sky, and so on; a double skin glass facade contributes little to improve thermal aspects in our climate. 

The facade of GAES headquarters in Barcelona is a risky proposal. In filt3rs.net we addressed the behavior of the green filtering elements; here is the time to comment the facade solution as a whole.

The glass facade has always been characterized, among other things, for being supported by an industry capable of ensuring its continuous development and evolution to be adapted to new functional and formal requirements. A fact that is unquestionably a value, has the counterpart of a relatively fast obsolescence of the facades that results in the need to replace them quite frequently.

In the Beethoven Building in Barcelona, the replacement of the facade clearly renews the image of the building while maintaining the idea of continuous glass enclosure and the original cutting. Different materials and characteristics of both the glass and the profiles, but above all, it is the strong rhythm conferred by the mullions covers and the couples of exempt profiles when projecting outwards that permit this renewed image.

The extension of the Faculty of Law of the University of Barcelona is one of these risky interventions: erecting 16,000 m2 next to a jewel of rationalist architecture of smaller size, about 12,000 m2; being the plot of the new construction of a dimension considerably smaller than that of the historic building. We do not aim here to value the architectural intervention, simply mentioning that the recourse to neutrality is perfectly understandable.

The unfinished Plaça d’Europa project arises from a contradiction. The objective was to provide the city of Barcelona with a more representative entrance from the airport, with towers that appear to be of tertiary use. And we say “appear to be” because many of these towers were in fact designed for residential use. This contradiction justifies the façade solution adopted in these towers.

Glass: lightness, transparency; that is the message the façade of this police headquarters building wants to give. And it achieves to do it even though the façade is nor light, neither transparent. Resorting to the horizontal serigraphy combined with the thin eaves projecting shadow over the façade contributes an image of dynamism typical of an inhabited interior. If we take a deeper look we will see the glass is quite reflective and the eaves are randomly distributed even in the opaque area of the façade.
