The first in-person meetings of the EU-funded CHEK project are over. On 16/17 February, TU Delft gathered the consortium partners (researchers, municipality officers, software developers, designers and construction and standardization experts) from all over Europe, to coordinate project activities. We had a tight agenda, but great discussions, presentations, workshops and of course, lots of fun. Many thanks to the TU Delft project team for the perfect organization of this event.
