The introduction of an energy management system is intended to continuously improve a company's energy efficiency. It is observed that companies use their own system, either for documenting the management system or the way in which energy data is recorded and managed. This gives the need for other systems to merge the data. In order to make the organizational and written procedures associated with the introduction and operation of an energy management system efficient and more standardized. This work creates a software-based solution to manage an energy management system effectively, instead of using nonstandard proprietary software to do the same. In the offered solution, the open source JEVis System is used as a data storage as well as an interface: the presentation is made on a browser using HTML and JavaScript.
