Located opposite commercial constructions with hardly any public visibility, the new Puma Energy HQ by Ruiz Pardo-Nebreda acts as a renewing element in the urban landscape. As a recognition of its successful combination of clear and honest construction and careful treatment of natural light, the Institute of Architects of Madrid recognized this building the Luis M. Mansilla 2016 award. The architects worked on the concept and design of the façade and carried out a passive solar protection analysis in order to optimise the entry of natural light into the building.

This analysis, combined with the choice of appropriate solar protective windows, allowed the architects to shape a continuous glazed façade concept on the inside, supported on the outside by a steel rib sequence with an equal distance between each rib that not only supports the windows, but also acts as an efficient system of sunshades. The result is an inverted stick system curtain wall which is able to withstand large wind loads caused by tropical storms, connected to a system of elastic joints and gaps between components in order to withstand seismic movements.

During the construction phase, local metal work was combined with products made by international manufacturers in order to obtain a façade which unites local craftsmanship with the performance of a building of international quality.
