With Priority Programs (SPP), the German Research Foundation (DFG) funds large research networks on currently particularly relevant topics. Spread across many locations, the interdisciplinary cooperation of the individual sub-projects generates new findings and synergies.

next question:

“2255” is actually just the serial number assigned to the Priority Program (SPP) “Cultural Heritage Construction” by the German Research Foundation (DFG). In conjunction with the abbreviation “SPP”, it now stands as a word mark for the research network in its entirety.

“Cultural heritage construction” stands for constructions in the building industry that are of particular historical significance. The work in SPP 2255 focuses on the era of high modernism (around 1880 – 1970). Their construction heritage is particularly interesting – and often particularly endangered.

In fact, even outstanding examples of engineering architecture are often completely hidden from public view. However, this does not diminish the perhaps extraordinarily high heritage value of these “hidden structures” – regardless of their visibility or even beauty!

Beyond classical architectural categories, the creations of engineers have written and continue to write an autonomous narrative of the history of construction. Especially in the buildings of high modernism, it is often the load-bearing structures and manufacturing processes that define the special monumental value.

For the future task of “engineering in existing buildings”, historical knowledge of structures and building materials is just as important as expertise in repair and refurbishment. The SPP 2255 therefore aims to establish networked assessment and action strategies.

Strategies and methods for the assessment and preservation of ultra-modern building structures have only been developed to a limited extent to date. With its interdisciplinary character, the SPP 2255 opens up new paths for the future handling of the multifaceted architectural heritage.

Looking back can also open up perspectives for the future. Against the backdrop of climate change and the finite nature of natural resources, SPP 2255 emphasizes the importance of mindful conversion and further construction as an ecologically highly effective alternative to new construction.

The SPP 2255 aims to increase historical knowledge, deepen reflection and refine methods as an elementary basis for the urgently needed valorization and further development of the cultural heritage of construction by new, interdisciplinary actors.
