Ever-increasing building density in urban areas means that infrastructure and organisation in many German urban areas is being asked to fulfil requirements that can barely be met. Additional challenges will arise in the future due to climate change. Urban areas store heat for longer than the surrounding countryside and therefore heat up faster in summer (Urban Heat Island Effect). In addition, resources such as drinking water and nutrients will be scarcer in the future.

VertiKKA aims to counteract this development by increasing energy, land and resource efficiency. The local quality of life is upgraded, climate protection is improved and the city progresses its efforts in adapting to climate change.

The social component has not been overlooked: VertiKKA installation should not cause an increase in rent (including heating costs). This prevents social displacement in the city's neighbourhoods. The project is intended to promote neighbourhood communities and actively involve citizens in decision-making.

The benefits of VertiKKA can be roughly divided into two categories:
1) Effects on the building on which the module is installed, and
2) Effects on the immediate surroundings of the building.
