Abstract

The energy effi ciency of the existing housing and the thermal insulation problems are the subject matter of this paper. A technical-constructive reading of the building organism, recently renovated or constructed, shows how almost all the composite elements, which contribute to the determination of the built space, the environmental comfort, and the reduction of energy needs, are formed by assembling more parts, in which the combination of the “traditional” and the “innovative” components guarantees a fi nal product able to satisfy the normative performances but not always the re-employment in similar or diversifi ed forms and functions. The present paper aims to focus on some functional construction elements (insulation and last generation windows) whose use, although representing an important step in the construction sector for the containment of consumption, needs careful evaluations on some aspects such as recycling and reconversion of materials in order to verify the eff ective eff ectiveness in terms of environmental and economic sustainability. For example, VIP (Vacuum Insulated Panel) is an insulation material consisting of a porous core material that is evacuated and then sealed into a barrier envelope. Mainly as a result of evacuation, the thermal conductivity of the material in the VIP’s core is a factor of 5 to 10 less than that of conventional thermal insulators. Vacuum insulation panels thus enable the development of very thin high-performance architectural constructions. In most projects, infact, this high-performance insulation.
