"Dimensions. Journal of Architectural Knowledge" is an academic journal in, on, and from the discipline of architecture, addressing the creation, constitution, and transmission of architectural knowledge. It explores methods genuine to the discipline and architectural modes of interdisciplinary methodological adaptions. Processes, procedures, and results of knowledge creation and practice are esteemed coequally, with particular attention to the architectural design and epistemologies of aesthetic practice and research. Issue 3, "Species of Theses an Other Pieces", is concerned with the form of the doctoral thesis in practice-oriented research. In reference to George Perec's "Species of Spaces and Other Pieces", this issue takes the love for playing with forms, genres, and arrangements as its program.

Die Praxis zeigt, dass viele Bürotürme aus den 1950er- und 60er-Jahren abgerissen werden. Dabei lassen sie sich auch an heutige Anforderungen und Bedürfnisse anpassen. Dazu sind nicht nur Abwägungsprozesse, sondern auch komplexe Planungs- und Umbauschritte notwendig. Eine einheitliche bauwerkserhaltende Vorgehensweise gibt es bis heute nicht. Dieses Buch stellt erfolgreiche Strategien und Konzepte zur Revitalisierung von Bürohochhäusern der 1950er und 60er-Jahre vor. Die Autorinnen und Autoren greifen dabei sowohl städtebauliche als auch baudenkmalpflegerische Aspekte auf. Dokumentiert werden drei Hochhäuser in Nürnberg, Frankfurt und Berlin, deren Sanierung umfassend dargestellt ist – von konstruktiven bis zu bauphysikalischen und gebäudetechnischen Lösungen.

The built heritage of postwar modernism has been under threat from climate change and the high expectations of society for years. The tremendous volume of building stock was erected with high hopes for the future within just a short period of time—and frequently using construction techniques that were as yet unproven. Despite the many research efforts focusing on spatial concepts and societal utopias between the 1950s and 1970s, the practice-oriented field of construction research lacks binding recording and evaluation strategies for buildings, materials, and construction methods for the majority of buildings of all types. This affects projects from solitary churches, residential settlements, and green spaces right through to large cultural, sporting, and education constructions, as well as the engineering structures of the urban and peripheral infrastructure. In order to preserve this existing stock as a resource for the future, new recording and evaluation tools that take into account technical, construction, ecological, and economic factors are necessary. This book presents possibilities for the management of our recent constructed heritage on the basis of ongoing projects by the DFG-Netzwerk Bauforschung Jungere Baubestande 1945+ buildings preservation network.
