Friendly and Affordable Sustainable Urban District Retrofitting

The FASUDIR project was born to develop friendly and affordable ways to support sustainable retrofitting of urban districts. Due to the complexity of urban retrofitting, the FASUDIR objective was to develop a new methodology to be implemented in an Integrated Decision Support Tool (IDST). The IDST would help decision makers from the masterplanning phase to select the best energy retrofitting strategy to increase the sustainability of the whole district.

The FASUDIR IDST is a software tool that enables modelling the district and its buildings through a friendly user interface to facilitate the interaction between the multiple stakeholders involved in the decision making process. The IDST allows end users to identify the most promising sustainable retrofitting strategies and technical solutions at building and district level, by creating a ranked list of optimised variants based on dynamic simulation results.

To ensure a good match of development and users’ expectations, FASUDIR organised Local Project Committees (LPCs) to identify the main needs of key stakeholders involved, such as urban planners and public authorities. The LPCs were involved throughout all stages of development, setting expectations and testing the beta version of the IDST.

The IDST was validated in three diverse urban areas to highlight the Europe-wide potential applicability. The areas were chosen to be representative of typical district typologies and climates: a cultural heritage district in Santiago de Compostela, Spain; a communist era district in Budapest, Hungary; and a 70’s residential districts in Frankfurt, Germany.

Key Project Outcomes

  • IDST core - The IDST dynamic simulation modelling core includes new Life Cycle databases for impact and cost, and uses up to date building and construction master templates to run simulations based on very simple data such as year of construction and typology.
  • Localised IDST versions - Available for each district in Santiago de Compostela, Budapest and Frankfurt.
  • Cloud based simulation server and API - Thermal models are hosted in a cloud server accessible via an API supporting connection to City Information Models and other interfaces.
  • Analysis support tools - Simulation results are analysed at district level for heat networks, energy synergies, and solar potential, and at building level to identify energetic weak points and financial performance.
