The “DigiPEQ” project (FFG No. 880562) explored the requirements and potentials of digital Positive Energy Districts (PEDs) in contributing to national and municipal decarbonization efforts and energy and climate goals. PEDs are identified as key in urban planning for energy sustainability, generating more energy than they consume through local renewables and digital technologies. Insights into ten thematic modules were jointly developed with innovative practitioners of sustainable building and district development, user-oriented and sustainable cooperation and business models, Innovative digital technologies for integrated, user-oriented energy systems and the establishment of replicable planning and operational management processes of Positive Energy Districts. Focusing on fundamentals, system boundaries, and framework conditions of digital, livable Positive Energy Districts, the project investigated dynamic assessments of energy and emission flows in PEDs, focusing on various system boundaries and conversion factors and how they can be quantitatively linked to municipal and national climate goals and scenarios. Several key strategies for enabling energy flexibility, load shifting, grid services, sector coupling, and maintaining user comfort and acceptance, as well as aspects of load prediction and user behavior are investigated, highlighting the importance of adaptable control algorithms and the consideration of grid status in PEDs. The project further addressed the energy economic, legal, and technical environment, emphasizing the need for regulatory frameworks to support PED development. Considerable legal and administrative barriers to PED implementation and near-term scalability were identified. The project underscored the significance of participative design and information management in promoting sustainable behaviors in PEDs.It also explored the application of new digital technologies like ML, AI, and Web3 in PEDs. Finally, the project highlighted the relevance of PED topics to practitioners and outlined strategies for knowledge and skill transfer in PED development, and a criteria catalogue is presented to steer and assess early PED development and planning processes in practice. In conclusion, DigiPEQ demonstrates the promise of PEDs in urban energy transitions, offering insights for future district design and the role of digital technologies in this process.
