NEB Junction collects, packages and validates stakeholder knowledge into Knowledge Gems, and makes them publicly available in an AI-supported, attractive and accessible IT Portal. We cooperate with a broad set of NEB stakeholders - and stakeholders that might not yet be interested or are traditionally excluded - using multi-stakeholder sessions, learning journeys and stakeholder assemblies. Our Monitoring System bridges cultural and creative perspectives with environmental, economic, social, health and governance aspects, making sustainable solutions more relatable and attractive to policy makers, public authorities, construction ecosystems and local communities. We connect stakeholders with the NEB Facility through NEB Coffees, mapping of R&I gaps, foresight activities and more, to distill NEB at your Fingertips - Pathways to NEB Implementation, and a Roadmap for the NEB Facility. We work with creative and cultural sectors and industries to generate a sense of belonging to NEB, combining AI-supported analysis with human reflections on NEB values, needs and expectations in a co-design approach. All of this work is supported by a Vision co-created with the stakeholders, enabling its long life-time also after the end of the project. The NEB Junction is created and managed by 8 experienced NEB partners: AIT, Ars Electronica, Climate KIC, DemSoc, DOWEL, ERRIN, ICLEI, and NTNU as Project Coordinator.
