Adaptive Reuse as a Strategy for Sustainable Urban Development and Regeneration

November 04, 2023

“New ideas must use old buildings,” said Jane Jacobs in her seminal book The Death and Life of Great American Cities, championing the reuse of existing building stock as a means to catalyze positive change and foster diverse urban environments. Inserting new activities within an existing framework is increasingly becoming a defining aspect of contemporary architecture, as the need for sustainable alternatives to building anew turns more urgent. From an urban perspective, adaptive reuse is a valuable strategy for revitalizing post-industrial cities, creating density and mitigating urban sprawl, or helping shrinking cities redefine their urban fabric.

Minimalist Windows with High Rigidity Steel Profiles: Transparency and Subtle Design

Subscriber Access | November 09, 2019

After centuries of using wood for the development of window and door carpentry, the Rationalism of the 20th century began to adopt a new material for these purposes: steel. Driven by industrial production, and promoted by architects such as Adolf Loos, Mies van der Rohe, and Le Corbusier, steel was evolving to generate increasingly thin and resistant frames. However, efficient and low-cost materials, such as aluminum and PVC, gradually began to replace its widespread use, increasing the size of the frames and losing steel's "clean" aesthetic when applied to a growing architecture of large glass paneled facades.

At present, new technologies have refined their production processes, developing minimal profiles of high rigidity and precision, which take full advantage of the transparency of the glass and deliver new comfort and safety features. We talked with Jansen's experts to deepen our understanding of their application in contemporary architecture.
