Energy Efficiency Indicators E-KPI

1. Comparison with goals: EKPI is often compared with set energy efficiency targets. These goals may be determined based on:

• • Historical performance of the company.
  • Industry standards.
  • Norms and regulations concerning energy efficiency.

2. Time trends: An important aspect of evaluating EKPI is trend analysis over time. A rising EKPI result may indicate a decrease in energy efficiency, which may require optimization measures, while a decreasing result suggests improved efficiency.

3. Comparison with benchmarks: EKPI results can be compared with industry benchmarks to understand how the company performs relative to competitors or industry standards.

4. Absolute and relative values: EKPI can be evaluated based on:

• • Absolute values (e.g., energy consumption per ton of produced material).
  • Relative values (e.g., percentage reduction in energy consumption compared to the previous period).

5. Operational context: The EKPI result should also be assessed in the context of operational conditions, such as changes in production levels, the introduction of new technologies, changes in raw materials, or changes in technological processes.

6. Identification of areas for improvement: The EKPI indicator can also point to areas where there is potential for optimization and reduction of energy consumption, e.g., in specific technological processes, production lines, or even in building management.

1. Energy consumption (in kWh, MJ, etc.) relative to:

• • The quantity of produced goods (e.g., kWh per ton of production).
  • Production time (e.g., kWh per hour of machine operation).
  • Usable area (e.g., kWh per square meter of office space).

2. Energy costs: Efficiency evaluation can also take into account costs associated with energy consumption.

3. CO2 emissions: The EKPI indicator can also include the aspect of carbon dioxide emissions as an environmental metric.

Assessing e-KPI changes should be done over various time intervals to better understand both short-term fluctuations and long-term trends.

• • Annual Assessment Period – A practical approach is to analyze results over the past twelve months. This long-term perspective helps smooth out the results and minimizes the impact of short-term anomalies. It allows for better identification of overall trends and helps avoid incorrect conclusions based on isolated events.
  • Shorter Periods (monthly, weekly, or even daily) – These are used to monitor short-term changes that could influence future trends. Analyzing data over shorter periods helps identify anomalies, such as sudden increases or decreases, which may have a short-term impact but could also signal more permanent changes.

By applying a multi-level analysis, companies can better understand the dynamics of e-KPI and make informed decisions both in the short and long term.
