A research project for the development of multifunctional green façade elements using waste water and in combination with façade photovoltaics

Photovoltaics and roof or façade greening systems often compete with each other in urban development. VertiKKA aims to combine the two. In many respects, urban greenery is of particular importance for a city climate and represents an important instrument of sustainable urban development. Especially in a densely built-up city like Cologne, new, innovative and smart forms of urban greening, which go beyond conventional façade and roof greening are desirable.
