UAB ,,Biržų duona“, legal entity’s code 154838481, located in Plento g. 6, LT-41128 Biržai purchased energy audit service from UAB „Energy Advice“. We acknowledge that UAB „Energy Advice“ performed energy audit was comprehensive. Recommendations for reducing transport fuel consumption, optimal renewable energy source integration and operation, reducing heating generation losses, an increase of electrical network reliability, and installation of an analytical information system were provided. UAB „Energy Advice” specialists presented results and answered questions regarding our concerns.

Multimeda is one of the biggest solid wood furniture manufacturers in Lithuania. In our production facilities we use dust collection systems with a total installed capacity of over 350 kW. These systems contribute significantly to our energy consumption, therefore, we ordered Energy Advice services to find energy mitigation opportunities. Energy Advice team applied EA-SAS software, created digital model of dust collection systems in our factory and calculated energy saving potential. The main finding was that due to big cross section area of main ducts, air flow speed can be too small to transport heavier dusts, therefore fans’ speed control cannot be done with existing ducts design. However, EA-SAS calculations also showed that by selecting optimal cross section area of ducts it is possible to ensure required air speed even with reduced fans’ speed. This would allow to save over 15% from dust collection system’s energy consumption. Therefore, we recommend EA-SAS Ventilation program for other companies that face problems with dust collection systems.

We confirm that Energy Advice has developed a Digital Twin for the glass melting furnace. Energy Advice has installed EA-SAS software, developed a mathematical model of the glass melting furnace, and commissioned it. Digital Twin model allows us to monitor glass furnace process remotely, also as control technological process in real time by providing optimum operation setpoints. Project benefits: reduced energy consumption for glass melting process, increased glass furnace life time, identified furnace maloperation, determined components efficiency. The project was implemented on time. We recommend Energy Advice as reliable partner for Digital Twin development and implementation.

UAB “Šalčininkų šilumos tinklai” confirms that UAB “Energy Advice” has carried out a digitization project for a biofuel boiler house (5 MW). EA-SAS Boiler system monitors, analyzes and evaluates the efficiency of the boiler and perform automated control in order to increase production efficiency. The implemented solution helps to burn fuel more efficiently, the boiler NVK has been improved. We managed to prolong time between maintenance due to data analysis. We recommend UAB “Energy Advice” as a reliable partner in digitization projects.

UAB “Šalčininkų šilumos tinklai” is a district heating company and supply ~18,5 GWh heat per year. We have been using UAB “Energy Advice” solution EA-SAS Heating based on Digital Twin technology from 2020. Thermo-hydraulic calculations and real time date evaluation is performed constantly in order to control the network and reduce losses. The digital model of the heating network also allows us to make fast and high-quality network development decisions. We confirm that even small town heat supply companies benefit from digitization projects, and we recommend Energy Advice as a reliable partner in digitization and energy saving.
