Within the context of the international BAU Congress Beijing, China on 8. July 2014, Jürgen Engel delivered a presentation on the theme "Functionality, Sustainability and Identity - Architecture in and outside Germany". Taking as example the ongoing constructional activity of KSP Jürgen Engel Architects in Germany and other countries - including projects characterized by a particularly sustainable and environment-friendly energy concept - Jürgen Engel described how the the aspects of functionality, sustainability and identity define the architecture of his office. Furthermore he presented other projects marked by the keynote of sustainable city planning, such as „Science and Technology City, Qingdao, China“, and projects whose powerful identity makes them impulse providers for a new city development, such as the world's 3rd largest mosque in Algiers. The event was chaired by Boris Schade-Bünsow, Editor in Chief of Bauwelt, and Prof. Lu Wang.
