A unique versatile filter in Alcayna, Murcia 
The project report provides the key to the selection of filters: "The project considered to enjoy magnificent sunsets without being excessively penalized by the heating of the western sun in summer." The longest facade has a south-southwest orientation, the one with better views. The most suitable material is probably the deployé, since it offers enough permeability to views while protecting from the sun even for lower inclinations of it. The images show that transparency while the shadow on the floor of the terrace shows the effectiveness of the solar protection.
