Their participation is included in almost all phases: The utilization of available tools in selecting energy-efficient measures and interventions assure more accurate analysis and allow to avoid mistakes and waste of resources. In CITyFiED methodology, several tools have been proposed, as they are collected in the following paragraphs, as CITyFiED Key Performance Indicators (KPIs) for district renovation, Energy Simulation Software tools, Geographic Information Systems (GIS) tools, Life Cycle Cost Analysis (LCCA) tools and the proposal of the CITyFiED Replication Model.

RENOVATION In this framework, it is recommended to follow a collaborative work approach. This means to take into account organizational and management aspects (periodic meetings, reports, etc.), but also including other drivers to achieve a fluent cooperation. In this sense, it is recommended to follow Integrated Project Delivery (IPD) principles [10] - to the maximum extent that the public procurement allows – and Building Information Model (BIM) tools and approach that provide a common communication and work environment. In recent years, different frameworks for performance measurement have been developed in order to evaluate urban systems. CITYKeys, SCIs and CONCERTO are only examples of the several initiatives and projects that have been carried out to elaborate efficient methods to collect, monitor and compare data across European cities. CITyFiED project aims to give its contribution proposing a set of Key Performance Indicators that supports the validation of the innovative methodology for city renovation at district level and the assessment of the retrofitting processes in three demonstration cases. 3.2 P ROVIDING S UPPORTING TOOLS FOR DECISION - MAKING The CITyFiED project aims to develop a methodology that supports local authorities in implementing holistic strategies to move towards energy efficient districts. As previously mentioned, the collaboration between stakeholders plays a key role in the decision-making phase of district renovation, but another aspects that can support and ease this process is the integration of a set of tools that can be implemented through the whole project. Since the CITyFiED methodology aims to facilitate the decision- making process towards the development of Strategies for Sustainable Urban Renovation, CITyFiED KPIs consist in an assessment framework that covered the seven phases of the procedure. Because of that, this assessment framework is divided in three levels:  City indicators (Level 1), Figure 2: Proposed tools for the decision-making process 27
