摘要

Tropical butterflies can not be housed in air conditioned spaces. To reproduce the climatic conditions of the tropical forest, at the Zoological Institute of the University of Catania a special multifaceted greenhouse was designed as to keep constant in the day and through the seasons the natural solar heat gain. In the tensi-structure of the Sport Palace of Palermo, the shadowing of the fully glazed opposite ends of the building is controlled by two spectacular array of 27m. long stainless steel pipes describing two different warped shapes in space. They also are functional to carry off the rain water collected by the 60m. span, 100m. long concave roof whose intrados is cooled by a laminar air flow naturally activated.
