DSO Tezno – ENIS and BAS
Energy monitoring and information system in connection with the monitoring and regulation system
CHALLENGE:
Increasing energy efficiency and managing processes and monitoring the operation of energy systems.
SOLUTION:
In modern buildings, a building automation and control system (BAS – Building Automation System) is a key solution for improving energy efficiency, as it enables comprehensive control of processes such as heating, ventilation, air conditioning and lighting. With automated monitoring and management of these systems, significant energy savings can be achieved, operating costs can be reduced and better control over the operation of the building can be ensured.
In addition to the BAS system, the Energy Monitoring Information System (ENIS) also plays an important role, enabling in-depth analytics of energy consumption, long-term monitoring of efficiency indicators, and support in decision-making and optimization of the operation of energy devices. The BAS and ENIS systems complement each other, as the BAS provides operational management and control, and the ENIS provides strategic overview and data analysis. Their integration represents the best available technology (BAT) in the management and control of processes and energy-intensive buildings, as it enables simultaneous management of daily operations and long-term energy optimization.
EMPHASIS:
The introduction of the energy monitoring and information system ENIS has enabled savings in the supply of final energy (-20%). After the introduction of the BAS, DSO Tezno has the lowest energy consumption in history. They also have all major energy systems “under control”.
“We have been cooperating with Enekom since 2012, when we introduced the Energy Monitoring Information System (ENIS), which established comprehensive energy accounting and enabled precise control over the consumption of all energy sources (electricity, heat, water). The system enables monitoring of energy indicators, identification of deviations and targeted energy optimization. In the first few years, energy savings of 10% were achieved compared to the baseline.
The introduction of a central control system (BAS) in 2023 enabled automatic optimization of operating modes of technical systems (HVAC, heating, ventilation) based on occupancy, operating schedules, and analysis of data from ENIS. This resulted in higher energy efficiency and reduced unnecessary energy consumption.
To date, the total savings amount to more than 3 GWh of energy, 30% of which in the last two years, coinciding with the introduction of the BAS. In addition to the energy and cost benefits, a significant environmental impact has been achieved – a reduction in CO₂ emissions of 1,720 tons.
This confirms that the symbiosis of the ENIS analytical system and the operational BAS represents the optimal approach to integrated energy management of larger facilities or facilities with distributed infrastructure.”
