The building is located in Paseo de la Castellana, an urban promenade where a collection of architectural masterpieces from 19th century until nowadays is displayed, which obliges to reflect on how to design in the 21st Century. And this reflection is twofold, considering how the technical and the aesthetical dimensions of architecture might converge in a building which integrates and reinforces them.
If there is contemporary architectural paradigm, it should integrate environment, health and wellbeing. The search for an environmental-aware architecture cannot be disconnected from the wellbeing and enjoyment of its inhabitants.
The understanding that an office building is a dissipating typology, sparked the search on the one hand for underground heat sinks, and on the other hand for solar protection, questions which finally converged in the construction of a set of interior spaces which are naturally-ventilated and are tempered by radiant surfaces, attaining healthy and intense workspaces.
The building poses an alternative to the typical air-conditioned sealed envelope office building. First, the curtain wall gives way to a faceted envelope which, due to its morphology, reduces solar impingement. Second, the air-conditioning gives way to a radiant system embedded in the concrete slabs which tempers the interior through the elimination of suspended ceilings. As a result structure and climate control are integrated through a convergent strategy which overlays tectonics and thermodynamics.
The aesthetic dimension of the building addresses the phenomenological vein of architecture. It understands that —similarly to the work of artists such as Olafur Eliasson or Arnaud Lapierre— perception unfolds a collective and shared aesthetic experience which forms part of architecture. The building is wrapped in a solar envelope which, acting as a kaleidoscope, intensifies the experience of Madrid’s skies. It presents a building which through the multiplicity of changing reflections becomes a shared public experience.
The interest of the project resides in how these two dimensions, the technical and the aesthetical, converge in a building which combines the most essential needs of architecture —environmental or corporeal— with a new collective aesthetic dimension.
