Dynamics sun screen system, Best practice

A dynamic façade, using glass and curtains, was designed for a specific project on a small conference room, in an office building in Rome. During the summer months, the façade of the building receives only a few hours of direct radiation in the morning, then the adjacent buildings create shade. This condition made it possible to conceive a volume with a large glass surface, a solution that in a different condition, with greater irradiation, would have been difficult to achieve in Rome. The first skin is a glass façade, while the inner skin is made up of two roller blinds overlapping to form a 60 cm air space. The curtains are made of interwoven narrow mesh fibre sheets, the first is white fibreglass with a high reflecting power and diffusing light, the second is carbon fibre with a high darkening power. In winter, the curtains are used only to diffuse the light inside or decrease the level of lighting. In summer, the curtains are lowered and generate the air space. The vents, placed on the floor and at the top, open generating an upward flow of air that expels the accumulated heat. When the temperature in the air space increases, the flow of air from natural first becomes forced and then, to further increase the heat exchange, the air is cooled. During the summer months, the façade of the building
