IUDeC – International Urban Design Competition Studio

The IUDeCS International Urban Design Competition Studio is a student competition jointly organized by the ISU – Institute for Sustainable Urbanism, TU Braunschweig and the CAUP College of Architecture and Planning, Tongji University. It brings together students from both universities to jointly explore solutions to one of mankinds most urgent challenges: sustainable urban development. Together, we seek to investigate sustainable strategies and future-proof concepts for „Low Carbon Communities” in Germany and China. We explore the potentials of real existing sites, to propose pathways for a livable and sustainable future.

The teams from Germany and China work towards the same goal, but on sites in their own country with local university peers. After submission, an interdisciplinary jury with specialists from China and Germany will jointly evaluate the submitted proposals. Projects from both universities will be awarded. In an experimental approach, the jury will be held online so that all participants can listen in and experience the jury’s discussion. This will facilitate learning across borders and cultures.

IUDeCS is hosted for the first time. For us, IUDeCS is an open process and experiment by which we seek to explore new ways of collaborating in teaching across time zones, borders and cultures. Please, bear with us, should we have not foreseen difficulties that may arise during the competition process. Should our joined endeavour generate positive results, we are planning to open IUDeCS to more universities in coming years.


We wish you best of luck for the competition!

Main objective of the international idea competition is to design a Low Carbon Community of each 10,000 people for a respective site in Berlin, Germany and Shanghai, China. The term of Low Carbon Community for us envisions qualitative and quantitative aspects alike. How will we accommodate the urban growth of the nearby future without risking present and future generations livelihood? What is necessary to build a lively, sustainable urban town or district that has a high quality of life, fosters feelings of belonging and social cohesion? How is such a new urban district designed to use as few resources as necessary? How can such a new district or town provide resources or amenities for existing neighbourhoods with a lack thereof? The goal of this student competition is to explore the two given sites to understand their spatial, social, environmental, and economic realities and, based on that, to develop specific proposals for transforming the areas into a Low Carbon Community.


The Competition Brief and related documents will be published on on  10 October 2022 (Site: China) resp. 24 October 2022 (Site: Germany).
