Protection has always been the most genuine function of architecture. In the context of global warming one of the most needed type of protection is from and against the sun. This necessity has led to an impressive creative outburst of amazing technological developments for all kinds of roofs without walls. These come in all forms and sizes, in a wide variety of materials  concrete, fabrics, fiberglass, wood or plants, to name a few. This volume features serial productions as well as individual designs. These shadow-providing devices range from elegant sun blinds and canopies, to fancy pergolas and luxury tents as well as small pavilions in public parks, wide covered piazzas, and even entire buildings shielded by independent overlapping roofs. With texts, facts, drawings and photos the presentation of the projects focusses on the design as well as on the constructive aspects and technical features.
