A double skin glass façade has indisputable formal possibilities, such as blurring the structural and/or functional order, providing uniformity and vanishing the volume limits so they merge with the sky. However, it contributes little to improving thermal aspects in our climate. 

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.

Batlle and Roig designed a double skin façade for this office building in 22@. The inner layer meets the thermal requirements and those of air and water tightness, while the outer layer delimits the building volumetrically and seeks to improve its thermal behaviour.

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 façade clearly renews the image of the building while maintaining the idea of a continuous glass enclosure and the original cutting. The renewed image is created by the materials, the characteristics of both glass and profiles and, above all, the strong rhythm conferred by the mullion covers and the couples of exempt profiles projecting outwards.

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).

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 University of Barcelona’s Faculty of Law was a risky intervention: the erection of 16,000 m2 next to a jewel of rationalist architecture of a smaller size, at about 12,000 m2, being the plot of the new construction considerably smaller than that of the historic building. 

This emblematic building in the London financial district maintains its formal unity beyond the differences in the design of the façades depending on their orientation. The case "Devoid of the human scale (034)" describes the southwest façade of the same building. The southeast and northwest façades attract our attention due to the sobriety conferred by the enormous glazed surface, which is only interrupted every three floors by horizontal bands of stainless steel.
