In 2023, activities for the purposes of the energy audit in accordance with the provisions of the Energy Efficiency Act of 20 May 2016 continued at the branches (ZKO) and at the headquarters of our company in Konstancin-Jeziorna. The audit was carried out by an external company and one of the outcomes was the identification of modernisation works and other measures aimed at improving energy efficiency. Some of the audit recommendations are implemented on an ongoing basis while others are at the planning stage. In addition, other solutions are also being put in place to improve energy efficiency.
ENVIRONMENTAL IMPACT AND CLIMATE ACTIONSEnergy efficiency
At PSE, systematic activities are carried out to increase the efficiency of energy use. They include energy efficiency upgrades to equipment and buildings and changes in the way they are used.
Measures to improve energy efficiency implemented in 2023 and planned for the years ahead by location:
Konstancin-Jeziorna
Activities performed in 2023:
- Partial replacement of light fixtures with LED fixtures in offices.
- Continuous training and optimisation of the way electrical, HVAC and plumbing systems are controlled from the BMS.
- Replacement of uninterruptible power systems (UPS) with modern energy-efficient equipment, along with optimisation of the number of units and of the operation, control and power distribution model. The work was completed in August 2023.
- Installation of a fan speed controller in the dry cooling tower of the chilled water system.
Activities planned for coming years:
- Further successive replacement of luminaires with LED fixtures.
- Replacement of 5 condensing units (with two cooling circuits each) serving NDC air handling unit coolers (scheduled for 2024).
ZKO Bydgoszcz
Activities performed in 2023:
