CASTELLANA 77

Castellana 77

In the heart of Madrid’s financial center, in the AZCA district, stands Castellana 77, a building which has begun a new iconic life thanks to luis vidal +arquitectos. The original 1977 tower is now a 62-metre-high office building, defining the skyline of the city in its own special way.

With completion of the restoration, the building is a leader in terms of energy efficiency and environmental profile and has received the prestigious LEED Platinum certification. High performance glass products for the façade contributed directly to achieving this LEED certification.

Clever use of natural light and the desire to create a strong identity for the building to stand out in its environment were two of the essential pillars for the architectural project.  This has been achieved with an integral restoration, primarily focused on building a new façade with a sharp vertical modulation that utilises coated glass in a high selectivity glazed curtain wall.

This modern, inspiring construction system also incorporates an added feature that provides extra solar protection by using fins with a 60cm overhang to provide shade (separated from the main façade by a 15cm gap for maintenance and cleaning). These work in conjunction with glass to further improve the general performance of the building.
