Four universities of technology in the Netherlands join forces in the 4TU Federation to strengthen technical knowledge and stimulate the exchange of it. One recent ‘proof of concept’ research is Spong3D which is an adaptive 3D printed facade system that optimizes indoor climate control. The proposed system incorporates air cavities to provide thermal insulation and a movable liquid to provide heat storage where and whenever needed. A full scale 1:1 prototype was produced and used for extensive tests.

The 4TU Federation consists of TU Delft, TU Eindhoven, University of Twente and WUR. This research was lead by Maria Valentini Sarakinioti and Dr. Michela Turrin.
