Large companies have been obliged to carry out an energy audit according to DIN EN 16247-1, since 2015. This audit needs to be repeated every 4 years. In addition to fulfilling the legal requirements, the aim of this is the systematic and holistic analysis of the company's own energy efficiency.
Within the audit’s framework, energy efficiency measures are developed and ranked according to the criteria of "Efficiency First" principle, relevance, use of resources, technical and financial feasibility, payback period and effectiveness. At PROBAT, the following top 2 measures are currently being implemented:
1. installation of a combined heat and power unit (CHP)
2. replacement of the heating system
The installation of a photovoltaic system on the roof of the newly erected production facility was recently completed. It produces around 6000 kWh of electricity on average per week, thus significantly contributing to minimizing CO₂ emissions at the company’s headquarters. The usage of the so-called Sunny Portal, a platform for monitoring solar systems, allows for a precise monitoring of current carbon emissions savings.
Due to these measures, annual CO2 savings of approx. 244.940 kg are expected in the future.
