We want to know the exact amount of energy we consume and how we can limit it. For this purpose, Dettmer Rail commissioned a specialised consulting firm to conduct an energy audit in accordance with EN 16247‑1:2012, in which consumers and consumption infrastructure were analysed. Proposals for energy efficiency measures based on the audit results were developed and will be jointly implemented with rental companies. Dettmer Rail GmbH will also be switching its offices to green energy at the next opportunity.
