Sustainability Ecosystems: Control of the Energy Efficiency as One of the Aspects of the Digital Ecosystems (Case Study for Ukraine)

Ukraine needs a simple and straightforward procedure to demonstrate to buildings owners the improvement of their energy efficiency, which is exactly what the ISO 50001 "Energy Management Systems" standard requires. For the realization of this procedure, a city energy management system is created. It allows monitoring and control over the use of energy resources at the level of the house, district, city. The paper has presented the list of tasks for realization the system, tasks of the energy resources management system, stages of the system implementation and practical example of the system using. The practical result of the system implementation is to create a stable mechanism for the functioning of city energy consumption. The system will provide an efficient energy supply to the city to achieve the required level of energy efficiency of any objects, with the possibility of reliable and transparent verification of the obtained results.
