Abstract
In sustainable urban planning, monitoring and evaluation systems are crucial for guiding Public Administrations in making informed, responsible decisions. Despite the rise of sustainability guidelines, local implementation remains challenging. The GLOSSA research project (a GLOcal Knowledge-System for the Sustainable Assessment of Urban Projects) addresses this issue by introducing a multi-methodological framework based on operational indicators for urban project assessment. The framework is implemented in a multi-criteria evaluation software called Indicators’ Based Tool (IBTool) structured into 4 modules: i) Data Storage to manage a database of indicators; ii) Validation to assess indicators’ relevance through the Fuzzy Delphi Method; iii) Weighting to assign weights to the indicators’ and identify KPIs via the Best-Worst Method; iv) Performance/Impact Assessment to evaluate urban design alternatives using TOPSIS. This research innovatively integrates qualitative and quantitative evaluation methods into IBTool, bridging the gap between academic research and practical applications. The IBTool was tested in a case study in Italy to assess sustainable development levels.
