The overall objective of the project is the replication of European practices on professional risk assessment based on technical and financial due diligence. Furthermore, the project aims to develop a knowledge-base, and a sustainable training framework for all interested professions (engineers, economists, lawyers) and market players in order to be able to evaluate the projects together, regarding all aspects and criteria. The project pursues the following specific objectives: - to develop, document and establish practices for evaluating and mitigating the technical risks associated with investments in ESCO/EPC projects; - to develop, document and establish practices for valuing such risks when modelling the costs of an ESCO/EPC investments as investors do when evaluating the life cycle costs of such projects; - to evaluate how these evaluating and the expected return on investment in different business models vary; - to enable the key actors, and particularly the financial market actors, to widely adopt the project results as best practices for the mitigation of risks of sustainable energy investments with current and new business models; - to aggregate, systematize the relevant tools, know-how and best practices, and develop, and methodize a teachable knowledge-base; - to develop a web-based database, and interactive toolkit for professional and market stakeholders which is capable of drafting indicative offers based upon the data provided by the ESCO project host; - evaluation of best practices in the member states as far as the legislative background of implementing ESCO and EPC projects is concerned.
