The MIAS ARCHITECTS project for the headquarters of the company iGuzzini in Spain, with a spherical geometry and a total transparency, allows a solar protection of the building for its South, East and West zones. IASO designed a solution made of a double curvature membrane, in one piece, constituting the envelope of the spherical building, by being tensed on a geodesic structure made of nodes and of an aluminium frame.The membrane is actually a permeable textile mesh, an aesthetic product especially designed for façades. This textile, ref. FT381, provides great performances, particularly a decrease of the light intensity coming into the building. The singularity of the construction is given by the high transparency of the architects' project, and for which the concept of integrating a solar screen adds aesthetics to the final result and helps improving the thermal insulation of the façade.
The solution developed by IASO, based on the use of a doubly curved membrane made of stripes of different colours that follow the shape of the structure, contributes to the dynamic and colourful effect that was expected. By looking at the building from different angles, we can notice that the colour and the transparency of the building changes.
