The analysis of existing built environment shows that the critical values of the peripheral areas, together with the very poor energy performance of existing buildings and the levels of possible transformations they imply, may contribute, collectively, to formulate from light to radical proposals for urban and building retrofitting. In such urban contexts, the reading of urban spaces and the environmental evaluation of their use, both in relation to the intrinsic features of the buildings and with the outdoor spaces, take on a renewed importance. In terms of architectural structure, this importance is focused on the building shell, which can be properly re-thought by proposing new energy efficient technological solutions aimed at re-shaping the technical and formal aspect of the building. These solutions, although developed and conducted on a single building and at the building-level technology, thus contributing to re-function the spatial units, may also been conceived in order to positively affect the urban places and the surrounding environment, fostering a mending relation between the built space and the environmental boundary conditions. © 2011 Published by Elsevier Ltd.
