This project involved the realisation of smart energy management system in several buildings that are administrative headquarters in one of the Croatian districts. The first part of this project aimed at energy monitoring, tracking data on consumption and detailed analysis of each object, which led to installation of the smart control system. Each smart control system we create is costumised according to our clients needs and consumption, always aiming to reduce the costs of consumption. Energy metering and remote controlling in these buildings is primarly focused on colling and heating devices, which produce the most of monthly costs.
