Hierarchical aggregation of energy performance indicators in continuous production processes

摘要: Abstract The mitigation of the climate change requires a significant reduction fossil energy consumption in all industrial sectors. implementation formalized management systems supports industry to continuously improve performance which is measured using so called “Energy Performance Indicators”. One essential requirement for evaluation correction these indicators and corresponding baselines by influences external static or dynamic factors, e.g. ambient conditions, product spectrum plant load. This particular difficult large integrated production sites as chemical industry. In this contribution, an aggregation method proposed exploit analysis factors on lower hierarchical layers aggregated domain. Thereby, resulting indicator baseline consider identified from layers, facilitates allocation possible savings potentials. concept applied exemplarily site contributions each deviation are analyzed. verification improvement required ISO 50001:2018 helps decision makers prioritize investments efficiency projects. results can be used discussions with policy-makers, certification bodies other stakeholders targets.
