Climate Adaptation in Urban Regeneration: A Cross-Scale Digital Design Workflow

Abstract Urban vulnerability has many facets. Among these, urban texture and plot pattern, building massing density, greatly affect the microclimate. Thence, redefining regeneration design criteria for climate neutrality is crucial, including environmental factors in process at different scales. In light of change, despite this urgent call, adaptive approaches useful to assess trade-offs between scenarios microclimate quality are lacking. This paper introduces a novel digital workflow that integrates associated indicators design, adopting cross-scale approach. The main goal increase resilience built environment foresight future scenarios, by promoting climate-sensitive solutions. Environmental performances were analysed using tools implemented workflow, allowing analysis. Performance metrics calculated Weather Generator Energy Plus. With former tool performance comparative study been run varying morphological parameters computing intensity Heat Island. While, Plus was used simulate impact form UHI on energy demand, highlighting interdependence scales addressing optimal performance. results provide additional levels knowledge, both terms analysis scenario evaluation: impacts, envelope adaptation tested suitability Mediterranean city shown, exploiting research-by-design transformations 22@ Innovation District Barcelona. highlights correlation solutions lays foundations climate/design cross-talk help policymakers practitioners achieve goals.
