An Unusual Landscape: Technological Design for Roof

The roofs are a complex part of the architectural constructive system: they represent the attack on the sky, which has the role to mitigate the effects of weathering and to crown the building. However, they are also an unusual landscape that look from above, cover and protect their city. This paper presents an analysis of some interesting technological design works, conducted with methodological needs-performance approach. It is a part of wider research on energy and environmentally responsible retrofits of constructive characters of the architectural heritage in the Mediterranean area, conducted as member of the Inter-University Centre of Bio-ecological Architecture and Technological Innovation for the Environment (ABITA) and addressed to knowledge the local constructive traditions and bio-ecological potentiality of this existing building heritage.
