Refurbishment in a life cycle perspective for an eco-oriented public planning

The refurbishment of building stock, more and more, get to achieve interesting energy savings levels, but often do not consider the impacts associated with the building activities: i.e. production of construction and demolition wastes; environmental impacts associated with high-tech materials. Here, the extension to the urban scale of the procedure already developed and applied to the single building, to enhance in life cycle perspective the building components and the pre-existing materials, is presented. The aim is to draw up a first filing of an urban area to orient further design options to control environmental impact associated to refurbishment.
