Climate change has a major impact on urban living. The realization that the weather is getting more extreme and that we have to prepare for it is getting bigger and bigger. A green infrastructure of the city is an important solution. In this project, a unique plug&play green climate system for roof renovations will be realized. For the saddle roofs (slope roofs) of social rental homes, an affordable pre-fab system is developed in which roofs are covered with a combination of green mosses on the one hand and solar panels on the other hand. The result of this innovation is that in addition to the local generation of green energy, a lot of climate gains are also achieved by adding greenery on the roofs. Because the roof systems are developed prefab, they are affordable and can be implemented quickly without disturbing the vulnerable nature in the neighborhood. Apart from the climatic gains, this project generates significant social gains in neighbourhoods with social rental housing.
