Kohn Pedersen Fox Associates - Rafael de la Hoz
Madrid - 2003
The headquarters of Endesa, located in el Campo de las Naciones de Madrid. The complex is formed by two independent buildings, joined between them by a covered atrium that houses the entrance security services, the elevators and a footbridge that offer access to the different levels, in addition to playing a fundamental role in the heating, ventilation, and air conditioning of the building.
The atrium roof is formed by a 3,500m2 glass surface located between 30 and 40 meters above the floor, composed of glass sheets and intercalary SentryGlas Plus from Dupont. Each glass sheet is suspended from the exterior metal structure supported with PUNTpart Overhead Glazing, which guarantees the sheet's stability even after breakage of both components of the laminated glass.
At one of the extremes of the atrium, the building entrance facade can be found – a 25m wide, 24m tall glazed surface determined with 12mm thick tempered monolithic glass sheets, pointed-fixed in four places with stainless steel PUNTpart SP ball-and-socket joints AISI-316 and PUNTpart RM spiders.
The structure of the facade is composed of three large reticulate steel pillars suspended from the metallic roof structure as well as from a framework of stressed stainless steel that, distributed in crosses contained in different horizontal and vertical planes, are capable of transferring the wind load as well as its own weight to the pillars.
