*** Open access article: https://www.mdpi.com/2071-1050/12/6/2307 *** Cities are complex systems connected to economic, ecological, and demographic conditions and change. They are also characterized by diverging perceptions and interests of citizens and stakeholders. Thus, in the arena of urban planning, we are in need of approaches that are able...

Stakeholder participation is particularly important for the German energy transition (Energiewende). While there is consensus about its necessity, politicians, administrations, and citizens have to deal with the effects of infrastructure construction on a local level. The success of participation depends on several factors, to some of which digital...

For the built environment's transformation we are confronted with complex dynamics connected to economic, ecologic and demographic change (Czerkauer-Yamu et al., 2013; Yamu, 2014). In general, cities are complex systems being a ``heterogeneous mosaic'' of a variety of cultures and functions, characterised by diverging perceptions and interests (ibi...

With this report we propose new MTMs based on the “gap” between WP3 (tasks T3.1–T3.6) and WP4 (the pilots). We start with a description of the CoeGSS workflow and then proceed through the six tasks of WP3 in the same order as in D3.1. For each WP3 task we first describe the requirements from the pilots which are relevant for that task, then the gap...
