Years after the construction of the AC hotel in the Forum area, the one in Sants was built. The constructive solution adopted for the rain screen facade is practically the same in both cases. Again a lightweight enclosure when the use demands low thermal mass solutions.Again a reinforced frame supporting the window as the necessary structure to release an opening in this unidirectional facade structures. This frame, originally conceived to assume tolerances between the brick wall and the window, far from losing its sense gains new functions in that sort of facades.

The AC Hotel was one of the first buildings in Barcelona where it was used a ventilated façade system with a light interior layer made of cement boards over metallic folded sheet profiles. Since then, these systems have evolved looking for a clearer solution for the edge of the slab according either to the continuity of the thermal insulation as well as to guaranteeing air tightness –achieved by the cement boards and an adequate joints treatment.
