The multiple benefits approach in energy requalification projects

Climate change is a major global challenge in the 21st century. Cities play a crucial role in addressing this issue, but we must transform them into opportunities. Over 50% of the global population lives in cities, and as urbanization continues, we need ecologically friendly and sustainable cities. All stakeholders, from corporations to citizens, must be involved to ensure no one is left behind. One approach is recognizing the multiple benefits of smart neighborhoods. Multiple benefits refer to the positive impacts of a project without ranking prejudice. Smart neighborhoods focus on energy performance, local renewables, digitalization, and social needs. Although the concept of multiple benefits was introduced by the International Energy Agency, it remains challenging to evaluate complex entities like neighborhoods. This thesis explores multiple benefits using insights from European projects (ARV and ProLight) and IEA-EBC Annex 83 on Positive Energy Districts. The research involves hypothesizing benefits, discussing with stakeholders through workshops, and using a questionnaire with the Best Worst Scaling technique. This approach identifies significant benefits for different stakeholders and types of smart neighborhoods, considering non-financial impacts. The findings prioritize benefits for each stakeholder category and inform investment in urban energy transitions. The Multiple Benefits approach is valuable when urban changes impact social dynamics. It benefits environmental sustainability, social equity, and economic development. Addressing climate change requires a multifaceted approach with all stakeholders involved. The Multiple Benefits methodology develops strategies for sustainability and resilience while considering stakeholders' interests. To encourage the energy transition, sustainable organization of territories like smart neighborhoods is essential. Projects benefit community well-being, energy efficiency, and sustainability, emphasizing the need for urban regeneration.
