The ground floor is conceived as an urban hub, a space returned to the city that integrates public use elements such as bicycles scpace or smart post-boxes and generates a flexible space that allows an adequate development for heterogeneous activities inside. The upper floors also accommodate public uses. However, they are structured in a progressive gradient of privacy and silence.
Bioclimatic strategies, together with the installation of high efficiency climatization equipment, make it possible to justify more than 70% of the savings in non-renewable primary energy, becoming a building with almost zero conssumption.
