This system for external shades notably reduces the thermal transmittance of a building, while giving the building a distinct architectural appearance. The shades intercept the rays before they arrive at the transparent surfaces reflecting most of the rays externally and only a minimal portion internally. Furthermore, the solar radiation absorbed by the shades themselves is externally dissipated at the facade increasing the efficiency by up to 30% compared to the internal systems, thanks to its' natural ventilation system.
