Abstract
On the basis of Directive 2002/91/EC the energy savings in the buildings sector (residential, commercial, industrial, etc...) cannot be postponed; about 40% of the total energy consumption takes place in buildings, which is the highest percentage among energy consumers. The building design have to take into account all issues related to energy performance, and in special way, all those related to building energy use for heating, ventilation, cooling, lighting. Concrete precast panels, often used in industrial building, are currently used, in Italy and worldwide, also for wider application (e.g. commercial building, warehouse,..) and so this claims for their better energetic and thermal performances to ensure energy savings and well-being, achieving the function of separating the controlled indoor environment from the uncontrolled outdoor environment. This paper present the results of a numerical (using 3-D finite difference) and in-situ (experimental) analysis of a lightweight and thermal barrier panel designed to improve thermal and energetic performances respect to an actual lightweight panel employed in an industrial building located in the southern part of Italy.
