Telefónica’s new City of Communications, with its 140,000 square meters of glazed surfaces in the façades, is now the largest urban development in terms of glass ever carried out in Spain and in Europe.
The project, designed by the prestigious architect Rafael de La-Hoz, includes a façade formed by a double external glass skin connected to the interior façade via ribs of structural glass. The façade as a whole represents over 60,000 square metres of enclosure, and twice that in terms of glass surfaces.
The new corporate home of Telefónica, District C, which by size is the largest corporate project in Europe and one of the largest in the world, houses its twelve thousand employees in a single building to the north of Madrid, in Las Tablas.
For Rafael de La-Hoz, “District C also represents the first privately owned open space in Europe. The campus is open to all, 24 hours a day all year round, for anyone who wants to visit it.”
The difficulty of the project lies in ensuring a reliable design of the internal cladding as a whole, which is carried out as a modular façade system, and at the same time, enabling the glass ribs to be fixed across it, which bear the load of their own weight, and the frontal and lateral wind loads of the external glass cladding.
Officially opened on 8 October by their majesties the king and queen of Spain, the project was recently awarded the International Prize in the XI International Biennial of Argentina, BA07.
Rafael de La-Hoz wanted to create an abstract, transparent box, like an ice cube, and chose for this a screenprinted glass with black and white dots. Vitro Cristalglass presented a range of glass which fit perfectly with the wishes of the architect, and the chosen product was SUPERDUAL-T® combined with MULTIPACT® over extra-clear glass and SOLARLUX® Supernatural 70/40.
SUPERDUAL-T® is a product of Vitro Cristalglass designed expressly for this project. Its development broke former barriers and enabled a double visual effect to be obtained. Looking at the façade from outside it appears to be totally white, thanks to the multitude of tiny white dots applied to the glass; from inside and thanks to the optical effect, these dots are hardly visible, permitting total visibility through the glass. This singular feature might be used for even more avant-garde designs, creating holographic images which would be seen from outside and not from inside.
Façades with SUPERDUAL-T® glass enable substantial energy savings thanks to its optimal solar factor; this aspect is particularly important for large buildings, where optimising heating and cooling costs is one of the most important points to be considered.
