Poland – Poczta Polska
Modernisation of lighting in Poczta Polka’s sorting centres
The aim is to reduce the negative impact on the environment, electricity consumption and CO2 emissions and to ensure better working conditions.
Modernisation of lighting focused primarily on the replacement of lighting inside the halls, outdoor lighting and lighting in other buildings located in the sorting centre, for example guard rooms, administrative, technical and warehouse buildings.
One of the solutions used are astronomical clocks which are controllers that automatically turn on the light after sunset and turn off the light at sunrise. The DALI control system corrects artificial lighting depending on the natural light coming from the outside.
Modern and intelligent lighting, meeting the highest standards, contributed to increased energy environmental efficiency and improved working conditions. All previous upgrades at the five largest sorting centres are characterised by a fast ROI, which is also influenced by the monetisation of energy efficiency certificates. All modernisations were preceded by an energy audit of the company.
The estimated annual energy efficiency of the four sorting centres upgraded in 2018 is over 5,400,000 kWh. The efficiency gains represent more than 4,300 tons of CO2.
