The document is designed as a stand-alone document, the first chapters contain a description of EE services in qualitative way and the following chapters a description in quantitative way. The document provides a comprehensive view of the Smart EES Service Model design that was conceived in the framework of the BungEES project. The aim of the document is to present the developed detailed design of the upgraded service model, including the service structure and components, technical requirements and analysis. The cost structure, key resources and revenue streams associated with the proposed services have been analysed and are also presented in this report. The prototype model is a design that is based on existing models and is enriched with the necessary components to be in line with modern technologies and their capabilities. The design also reflects the strategic plans of the European Union and the individual countries for energy savings and energy policy. The document focuses on the various financing options, which include both internal financing and financing of the services provided. It also addresses aspects of flexibility, data use and management, and communication on energy flexibility needs. In addition, the report looks at the energy market and the benefits that an aggregator can bring to households and the energy market as a whole. An important part of the analysis is also the technical barriers that may hinder the implementation of the proposed model. The different needs and preferences of owners are also taken into account, as well as the legislative constraints and specific national barriers that apply to Slovakia, the Czech Republic, Portugal, Spain and Germany. This comprehensive approach allows for a better understanding of the challenges and opportunities that arise in the field of energy efficiency and flexibility and provides valuable information for the further development and implementation of innovative energy solutions.enreport
