In 2013 the IBA initiated a debate between local actors and internationally renowned speakers at its annual IBA_LAB conference. The »IBA_LABoratories« aim to deepen aspects of the theme »Wissen|schafft|Stadt« (knowledge-based urbanism). Local representatives from science, education, planning, administration and business have continually been debating with international speakers and the citizens of Heidelberg. Find out about the experiences planners and users have had both at home and abroad. Take the opportunity to chat to them and to Heidelberg specialists about what the city on the Neckar can learn from such examples of model architecture.
