WICONA façades in the Orona Ideo eco-efficient complex
WICONA developed the façade of the cylindrical, architecturally spectacular and energy efficient Zero building, helping it gain LEED Gold and BREEAM Excellent certification.
The Orona Ideo complex, the headquarters of the leading elevator and escalator brand in Spain, is located in Hernani (Gipuzkoa, Basque Country) and consists of four separate buildings: Gallery, A3 Research, Fundazioa and Zero. The most spectacular is this last building, which houses the brand’s corporate services department and part of its R&D department. Its façade, made with WICONA façade systems, consists of more than 2000
triangular ‘pixels’ that are either opaque, translucent or transparent depending on their position, their exposure to the sun’s rays or the use of the interior spaces. The building consists of a 16-meter-high cylinder with a 90-metre external diameter and a southward inclination of 15º, a symbolic evocation of the Orona logo. This inclination has made it possible to optimise the bioclimatic design, turning the roof into a huge solar panel that is completely integrated within the design. Part of the building is raised off the ground, giving access to the Galarreta Technology Park, and also representing the idea of the ‘gateway’ into the park. This access is by means of a central patio with a diameter of 45 meters, in which the entrance to the building is also located.
As regards the internal layout, as well as the entranceway, the ground and mezzanine floors house shared services such as the administration department, showroom, auditorium, laboratory, etc., and the upper floors contain the offices and work and research areas.
Transit within the building follows the curve of the central patio. The work areas are laid out on the opposite façade and are both diaphanous and flexible, adaptable to users’ different needs over time. Between the transit areas and the work areas the building has a services cluster containing the stairwells and lifts, bathrooms and offices.
A FAÇADE MADE WITH CUSTOMISED WICONA SYSTEMS
The Zero building, with a total floor area of 11,500 m2 distributed over six storeys above ground level, has a mixed concrete and steel structure. The interior mainly features technological materials such as aluminium and glass with wood counterpoints that add warmth.
Given the building’s design limitations, it was not possible to produce a geometrically efficient floor-to-ceiling construction solution, and the final solution chosen was a curtain wall that covered the entire building with a single skin created to the highest specifications. To create this solution, the system chosen was the WICTEC 50SG curtain wall.
The difficulty in designing the façade lay in the fact that the building has a polygonal floor plan while the walls and roof form a triangle. It was therefore considered advisable to create a system that would simplify the joints between the edges by concentrating them in a single point.
How was the façade designed? WICONA made modifications to its WICTEC 50SG system, the traditional rectangular design replaced by a trapezoidal frame with 15º internal and external angles. This meant that the mechanical elements of the crossbars were all on a single plane, thus facilitating the manufacturing and assembly process and guaranteeing the proper functioning of the façade despite the technical complexity of its structure.
Regarding the resulting curtain wall solution, Iñigo Marquet, Communications Director at Orona, highlights “its technological reliability, versatility to adapt geometrically to our requirements, the clean lines of a glass-clad façade, good maintenance and the elegance of the resulting façade”.
