Gullimex knocked on the door of property owner Wim Geul in the summer of 2019 to take a look at a climate system. The solution: Roofclix.

At the Jacobus Fruytier, there was a struggle with extreme heat in the summer and heat loss in the winter.

The effect of the Roofclix is intensively tested at The Green Village. The Green Village is located at the TU Delft Campus.
