ABSTRACT

The concept of sustainability, around which today the entire universe of architecture seems to rotate, sometimes so paroxysmally, isn't something new in the building historical tradition. There are many examples referred to the building tradition of man, a tradition that has paid a large attention to reusing as much as possible from the material resources, which have already been made available. However, the reflection on the use of this word seems more and more often to dwell exclusively on energy and economic aspects of the phenomenon, neglecting to consider that what is sustainable in terms of energy and economic costs, can be much less in terms of protection of other values: architectural, artistic and even of a mere historical-material witness. In this perspective, it seems to provide useful insights the theoretical re-reading of some experiences, both technical and historical, relating to post-war Germany: these examples are even more significant by the fact that they occur in a homogeneous cultural horizon, broken only by a fictitious boundary, which, up to the time of reunification in 1990, separated the Federal Republic of Germany (West) from the German Democratic Republic (East). The cases illustrated are, on the one hand some cases of restoration of historic Bavarian buildings: the Alte Pinakothek in Munich, restored by architect Hans Döllgast (1953- 1957); and, on the other hand, in a far landscape, the events that led to the loss of some historic buildings, including the Church of St. Sophia (Sophienkirche) in Dresden and the Church of the Leipzig University.
