DAAD Research stay: Concepts and solutions for Improving Energy Efficiency of Historic Buildings, in particular at urban district scale.

The energetic recovery has central importance for the achievement of the UE targets for the reduction of the emissions and on energy savings. But the situation of energy improving is more difficult regarding the historical buildings with architectural merit. As the present knowledge and the actual practices that usually use technologic systems propose two kinds of problems. The first one regarding the ‘decor’ bound to the saving of that part of the architectural heritage before 1945, of its architectural qualities and its specific features bound to the cultural and geographic frame work that generated it. A second one is about the incompatibility of the expected interventions with the chemical and physical features of the original materials. In this regard, the project must satisfy the need of the energetic efficiency in the buildings of the existing buildings heritage with an holistic approach, that knows how to compose materials, aesthetic and insertion in a context of a unique integrated in which the quality is the result of the interaction between the respect of the original project and the technological intervention and this can be both in the single building and in the scale of the urban district.
