Light: 75 kg/m2 < p ≤ 125 kg/m2

The building that MAP Architects designed in Borneo dock, Amsterdam, resolves the envelopes in a very appropriate way at all scales.

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.

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.

Again, this Catalan studio proposes a clear and simple façade. The dry constructed façade is based on three layers: the main one resolving air and water tightness, an inner cladding and an outer one. It might be thought that the façade works properly just with the main sandwich layer (like the Courts extension in Zaragoza). However, both claddings are needed for improved behaviour.

This hotel in Barcelona illustrates the typological confusion of contemporary façade systems and justifies the need for a taxonomic tool such as the one organised by this platform.

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.

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.

This emblematic building at the London financial district is characterized by keeping its formal unity beyond the differences existing in the design of the facades depending on their orientation. Case "Devoid from human scale (034)" talks about the southwest façade of this same building.Southeast and Norwest facades call our attention due to the sobriety that confers them the enormous glazed surface, only interrupted every three floors by horizontal bands of stainless steel.

The Forum Building façade has hardly been commented, maybe eclipsed at the time it was built by some other buildings in the area, and by some other aspects of the Forum Building itself. However, after fourteen years, this risky lightweight solution has completely succeed by being integrated in the town landscape. The original electric blue has slightly turn off at the same time that a salty dust patina has added enriching nuances.

Batlle and Roig resort in this occasion to a curtain wall where partial structures are assembled at each slab front without physical continuity between them. Glass panes are then supported over those partial structures to close the façade (have a look to "Cadireta" curtain wall structure). Each two glass panes are framed with an aluminum frame made with unitized panels profiles. Is it then a unitized façade or a curtain wall one? Maybe a mixture?
