Sustainable concept in building is mainly based on a limited energetic resources employment in construction phase of the building and during its life. It’s therefore very important give back to the building envelopment its thermal control function, to greater reason if it’s considered that new normative lines demand a certification that it guarantees parameters of the energetic consumptions of new and existing buildings. From this point of view it’s necessary to modify building envelopments to the aim to reduce the thermal system’s use. New scientific searches, recently conducted in various parts of the world, have been based about the thermic mass role carried out in massive building envelopments. The use of massive envelopments, in fact, is favoured thanks to the typical thermal mass ability to accumulate heat and to give back it slowly, more commonly indicated like “thermal inertia”. Within this problematic a search has been started with the objective to know better the massive envelopment’s performances. The present job means to communicate the results obtained, in the earlier stage of study, comparing the building envelopment’s thermophysical characteristics and the thermal performances realized in three different types and characterized by the use of brick, concrete and natural stone (Etna lava stone).
