EnVisaGe Plus continues the monitoring of implementation projects from the EnVisaGe project and addresses additional new research questions.

Research question

Three different research questions are the focus of this follow-up project to EnVisaGe:

  • How efficient are decentralized innovative local heating networks? Two implementation projects from EnVisaGe, a plus-energy district with large-scale geothermal heat supply and SmartGrid components and a solar thermal supported biomass local heating network are compared with the plus-energy district Ludmilla-Wohnpark in Landshut.  
  • Can urban industrial sites be supplied with energy from rural areas? Possible synergies between rural generation regions as "energy belts" for neighboring industrialized metropolitan areas are investigated using the plus-energy community of Wüstenrot and industrial customers of Stadtwerke Schwäbisch Hall. A systemic approach with transferable, integral solution approaches is to be developed.
  • Building on the findings from EnVisaGe, the project will investigate how sustainable heating networks can be implemented in rural areas, both for new construction areas and for existing buildings.


1. monitoring and cross-comparison:

Through intensive monitoring of the implementation projects from the previous EnVisaGe project (plus energy neighborhood, Weihenbronn heating network, school electricity storage facility), the efficiency of the technologies and control strategies used are analyzed, optimization strategies are developed and evaluated in a cross-comparison with the Ludmilla Residential Park "+Eins" in Landshut.

2. Rural areas as an energy supplier for urban centers:

Coupling of intelligent system control (heat pumps and electricity storage) with yield forecasts for PV and wind systems. Connection to the virtual power plant of Stadtwerke Schwäbisch Hall, in order to serve as a rural "energy cell" from an "energetic belt" as an energy supplier for large-scale consumers in neighboring conurbations and to generate local added value.

3. Sustainable heating networks in rural areas:

Based on the two innovative heating networks implemented in EnVisaGe, the research team investigates how sustainable heating networks can be realized in rural areas. In addition to new LowEx heating network concepts with decentralized solar thermal feed-in or isolated solutions that can grow together to form networks, various innovative investment, participation and operating models are also being examined here that will allow municipal utilities to increasingly implement and profitably operate heating networks for rural areas in the future.


Targeted results

The results will be summarized in guidelines and published. Usable results will be implemented in cooperation with the municipality of Wüstenrot and the municipal utility of Schwäbisch Hall.
