Starting situation

The constantly growing density of settlements and buildings in urban areas places demands on infrastructure and organisation, which can hardly be met in many areas of high population density in Germany today. In the future, climate change (e.g. changing seasonal precipitation patterns, heavy rainfall, urban overheating (Urban Heat Island Effect), increased cooling energy demand), deterioration of air quality, increasing noise pollution, declining biodiversity and increasing competition for land use will pose additional challenges.

Objective

Against this background, VertiKKA aims to develop an innovative technological approach to increase urban energy, land and resource efficiency, local quality of life and climate protection. The focus is on the conception and prototypical implementation of low-maintenance, self-regulating green façade modules with integrated photovoltaic elements. In addition, locally pre-treated wastewater (rainwater or process water) is to be used for irrigation.

Advantages

The VertiKKA offers a number of advantages, such as

  • Relief for sewage networks and sewage treatment plants,
  • Improved buffer capacity in heavy rainfall events,
  • Increased cooling capacity of buildings and reduction of heat islands,
  • Improved thermal insulation of buildings,
  • Improved air quality and fine dust pollution,
  • Production of renewable electricity through photovoltaics,
  • Reduction of noise pollution,
  • Aesthetic upgrading of the urban space and improvement in quality of life.
