Torre Iberdrola

Pelli Clarke Pelli

2007-2011

In July 2008, Félix constructions was awarded the mandate to build the glass facades of the Torre Iberdrola in Bilbao.

Client: Iberdrola
Main contractor: Iberinco Servicios
Façades: 24 000 m2
Type: New
City: Bilbao

Completed in 2011, this skyscraper dominates the city with its 41 stories, culminating at 165 meters. Built in front of the famous Guggenheim Museum, it is the central point of the regeneration of the Abandoibarra area, an old industrial area along the Nervion river, and it also reflects the new architectural identity of dynamic Bilbao, created by the best architects in the world.

The building was designed by the American architectural firm Pelli Clarke & Pelli, well-known for designing many iconic skyscrapers across the globe, including the Petronas Towers in Kuala Lumpur. With a slightly conical silhouette and shaped like an isosceles triangle with convex sides, the tower offers 50 000 m2 of office space, part of which is destined to become the new headquarters for Iberdrola, an international energy group of Basque origin, specialised in the generation, distribution and sale of electricity and natural gas. Iberdrola is very active in the development of renewable energies and is the leading global producer of wind energy.

The Torre Iberdrola is the first tower in Europe to receive LEED Platinum certification, the highest honour offered by the U.S. Green Building Council. This international standard certifies and classifies buildings according to their impact on the environment and the health of users, in line with the principles of sustainable development and economic efficiency.

The performance of the glass facades is one of the various solutions that made this certification possible. The tower’s casing is designed using the double skin facade principle, however the layers were inversed relative to the normal execution – with the insulating layer on the outside – in order to generate a greenhouse effect within the created cavity to allow controlled ventilation to regulate the temperature within the building.
