The project of the EBROSA facade includes the design of a double facade and its lighting. This office building is placed in the neighbourhood of Sant Chinaro in Madrid, close to the M40 highway. This facade, called Megaskin, arised from the need of isolating the building from its surroundings, firstly form noise and secondly, giving to the building a strong personality. The project of the facade wanted to create a huge protagonism and a clear differentiation with other buildings in the area. To achieve this ojective, we also use this megaskin as a giant screen light at night creatig effects and images of movement, colour and transtitions. This Light scenes of the installation were controlled through specific control sistem (DMX).
