Stakeholder involvement

In science, the numerous ESS of VG were previously investigated isolated from each other, and were not approached as a systemic solution by interpreting VG as a biological-technical system in an architectural-technical and urban context; neither were their inter- and trans-disciplinary aspects fully assessed . In practice, VG is often judged as an inadequately implemented sort of wild green, that causes annoyances, damages and high maintenance costs. No matter how important the ESS of VG are, if stakeholders do not implement and support VG, the concept will not unfold its ESS in the real world.

Future Scenarios Workshop September 2018 in Berlin

critics, prejudices, open questions

The first of our workshops was on future scenarios for vertical green in sustainable cities. It was prepared and moderated by Dr. Robert Gassner, an expert for scenario analysis methods. In a row of interactive discussion and creation formats - beginning with a substantial critics collection -  the participants developed and visualized their own perspectives, wishes and needs. Among the participants we had representatives from:

  • municipalities (Ljubljana, Vienna, Berlin Charlottenburg-Wilmersdorf)
  • tennants associations
  • real estate companies
  • environemntal NGOs
  • a food council
  • research and development companies
  • universities

The workshop was then analyzed the next day by the proejct team and the results were used for an adjustment of the project aims. Property rights on fassades was one of the interesting issue brought up by the workshop.

Constellation analysis workshop February 2019 Berlin


In a second workshop, threads and obstacles have been analysed in the format of an constallation analysis. This method has been developed by the Center for Technology and Society of the TU Berlin (ZTG). In this workshop, which was prepared together with Dr. Dorothee Keppler and Dr. Gabriele Wendorf, starting from an educated guess, we discussed organizational, political and technological barriers with the participants. Among them there were representatives of a The Federal Institute for Research on Building, Urban Affairs and Spatial Development, the Berlin Senate Departmentfor Urban Development, students, researchers and the civil society.

  • That vertical green is not listed in the catalogs of building materials was identified as one of the very practical obstacles. So well researched and proven physical values are needed. The CIBG together with the ZAE in Bavaria developed an according research concept.
  • Not the maintenance costs itself but the unpredictable height of the costs over the lifetime of the vertical green was identified as another difficulty (addressed in WP2, WP3 and WP5)

Workshop with Municipality of Ljubljana February 2019


The UIRS established a close cooperation with the municipality of Ljubljana, in order to discuss chances and challenges of vertical green for the city in detail and across all involved departments.


So, in February, after in depth interviews, 14 members of Ljubljana Municipality administration (not the interviewed), Heads/ managers of 8 different city departments and services participated in a stakeholder workshop which was moderated by a third party, a professional facilitator.

The key departments: Spatial planning dept., Public housing fund; Dept. of environmental protection; Dept. for development and investments; Dept. for education and child care and the City energy manager participated. After three introductory presentations: 

  • Jana Kozamernik – potentials and possibilities of green walls in cities,
  • Karin Hoffmann – assessment of green walls benefits,
  • Karel Pollak  MOL – Mala ulica case;

three workgroups of stakeholders were formed with the with task to think of five cases of possible VG implementation. Then they had to select one case per group and worked out the whole process  “from initiative to implementation” for the selected case.





Results of the action:

  • Raised awareness and understanding for VG implementation potentials and needs in Ljubljana
  • Exchange of opinions and experiences between relevant departments
  • Defined steps and process nedded for VG implementation
  • Selecting the prioroty cases for Ljubljana in that context identified:

  1. Retaining walls / blind facades / building sites fences (flat elements of street furniture)
  2. (Energy) renovation of public school OŠ Fužine
