The proposal chose an open building formation as a composition of building volumes (about 18.500m2), under a bioclimatic canopy, which intermediates between the natural environment of the hill, the urban fabric and is also influenced by the “industrial” characteristics of the facilities of EYDAP.

The new building was formed with a logic of a spatial succession of open and closed spaces and the alternation of bright and shadowy areas, which allow the environment to enter, as natural light and as a visual resource. The “free” space generated, ensures airy common areas, small atriums and an elevated internal distribution road. In this spaces, bridges, stairs and lofts create a flowing environment, allowing small groups, but also the broader community of employees to coexist.

The design philosophy of the office spaces embraces the modern perception that considers that workplaces do not simply “enclose” human activities but aim to create a multifaceted work “ecosystem”, enriched with alternative uses and images.

An extensive environmental design (green-scape, ground-scape and water-scape) preceded the integration of the new building. A large masterplan was formulated to separate the 3 planned zones and their entrances with the aim of connectivity with the city, the restoration of the ground relief and the utilization of natural resources.

In the nearest environment (Administration Zone), the landscape design is based on establishing a web centered around an internal pedestrian road that connects the various points, between which, an educational walk of 5 stops is created to understand the technical, cultural and social physiognomy of EYDAP.

The bioclimatic design of the building together with the energy design and the implementation of innovative systems for saving resources and utilizing the natural and climatic elements leads to a building with zero energy footprint and high energy efficiency and social utility.
