This is Orona’s central headquarters in Hernani, by Eneko Goicoechea & Xabier Barrutieta architects.

A landmark project with STUA products in three main areas.

– General relax spaces: Onda stools. – Restaurant: Lau tables and Laclasica chairs. – Bar & staff canteen: Onda stools.

A project for innovation must be innovative in itself. OronaIdeo is a project that stands out for being a space for fusion between different synergistic activities: the company, the technology centers and the universities.

One of the most important aspects of the project is applied innovation in urban and architectural design, complying with the highest sustainability standards. OronaIdeo is a benchmark in terms of putting the NZEB (Nearly Zero Energy Building) philosophy into practice as it addresses the joint design of various buildings, infrastructures and urban spaces to create a Campus integrated under the philosophy, which consists of seek maximum energy efficiency in buildings, source renewable energy and generate these energies within their own environment.

The project has been a pioneer in obtaining simultaneous Leed Gold and Breeam Excellent certifications for all its buildings, and has also obtained the first Innovation point ever awarded by Breeam Spain for the innovation made in lifting systems and their energy management.

The project consists of a series of buildings of different character that combined form a single project with a joint harmony. The bioclimatic design of the buildings has taken into account the passive use of energy through its orientation, the form factor and the envelope of each building, which has been solved with solutions tailored in each case and according to the uses in the interior of each of them. Green roofs, the use of rainwater, the local generation of renewable energy and the integration of solar energy capture surfaces in the design of buildings have been maximized.

Umetal worked closely with the project architects in order to develop the design of the glass ‘pixels.’ Once the final design of the opaque glass components was determined, the next challenged was to ensure that the translucent glass pixels achieve greater vision to the exterior while also contribution to the reduction of thermal U values. The design solution is based on the the principles of microperforation. The glass pixels have a triangular shape and are mounted in a ‘chamber’ with Unmetal glass (a decorative laminar glass) on the outside and solar control glass on the inside.

The Orona Zero building houses the corporate headquarters of the company and is inspired by the circle, a constant in the brand image of Orona. Its image seeks to transmit elegance, strength and elevation through an abstract formal gesture: a hollow cylinder of 90m diameter inclined 15ºs on the horizontal. Due to the way it touches the ground, this volume is detached from the ground creating a large overhang of 1,500 m2 in the area of the entrance to the Technological Park. And is buried in the opposite side, allowing it to pass through and generating a cover-facade for energy capture.

The curved facade is made with a curtain wall of a skin composed of more than 2,000 triangular pixels that have a different character - opaque, translucent and transparent - depending on their position and their different circumstances of exposure to solar radiation, access to views, relation with the use of interior spaces and the privacy of spaces.

Orona Ideo has achieved the Leed Gold and Breeam Excellent certifications and has been selected by the World Green Building Council for its Health, Wellbeing and Productivity report in office spaces.

Umetal has worked closely with the architects, managing and developing the design of the glasses - "pixels" - translucent and opaque. Once the final design of the opaque glasses was achieved, the challenge was to achieve that, on the same base design, the translucent glass had a greater vision to the exterior, and that the same design would contribute to reduce the thermal "U". The solution is based on applying the principles of microperforation to the design. The glasses have a triangular shape and are mounted in a “chamber”: Umetalglass® (Decorative laminar glass) on the outside and solar control glass on the inside.
