Monitoring the energy behavior of SMEs before and after Energy Efficiency measures: A case study

European Union’s target to achieve climate neutrality until 2050, along with the increase in energy costs, boosted the interest on improving energy efficiency (EE) in companies and especially in the small and medium-sized enterprises (SMEs). The SMEmPower Efficiency project, a HORIZON 2020 funded project, aims to address this issue by proposing a holistic approach. This includes also energy checks in real cases, i.e., SMEs. In this paper, a project pilot SME is presented and analyzed based on its real consumption and production measurements. The energy monitoring, targeting and verification (M&T&V) tools are used for the company’s energy data before and after the energy check. The adoption of the EE measures is evaluated using the M&V tool and the obtained results are compared to the CUSUM methodology.
