WP 1 - Urban Transformation Strategy

Under the SPARCS project (2019-2024) the cities of Espoo and Leipzig are pioneering the development of their own Positive Energy Districts (PEDs). This catalogue draws inspiration from the energy solutions tested in both Lighthouse Cities (LH cities), with the goal of creating a clear and accessible guide to facilitate the replication of PEDs in cities worldwide. Altogether, twelve energy solutions were selected to showcase effective implementation options for PEDs. These solutions are distributed across three levels: building, district, and city. Each solution is introduced by following a standardised structure, with a concise description that highlights key requirements, potential benefits and constraints, and encountered synergies with different energy typologies. To conclude, a simple framework with indicators is presented to allow comparison between solutions under the same level. The catalogue concludes with the demonstration of various strategies for stakeholder engagement, as developing energy solutions requires the involvement and participation of relevant stakeholders at every stage of the process.
