Key success factors of PED labs

Positive Energy Districts (PEDs) promise reduced climate impacts through surplus local renewable energy generation, yet their implementation remains complex. PED Labs—defined under JPI UE SET-Plan ACTION 3.2—function as “seeding grounds” to test innovative solutions in real urban conditions. This paper analyses existing PED Labs by examining scales (building to district), stakeholder engagement (public, private, research, community), and lifecycle phases (planning to operation). The findings highlight collaboration, transparent monitoring, and integrated planning as crucial success factors. They offer concrete guidance for policymakers, industry, and researchers seeking to replicate and scale PED solutions, for more resilient, sustainable urban districts.
