Energy Performance Indicators (EnPI) are absolutely essential for assessing the energy efficiency of companies and processes. They measure energy consumption in relation to production, time, area, or other factors, allowing for the setting of savings goals. They are as crucial for current evaluations as a car’s fuel gauge—or even better, its fuel consumption in liters per 100 kilometers.

Depending on the industry, energy can account for up to 10% of total operating costs. Interestingly, simply providing users with information about energy consumption and educating them on reduction methods can lower usage by 4-12%. Additionally, comparing performance with other companies yields positive results. Seeing how a company ranks against competitors provides a strong motivational boost, increasing engagement and driving efforts towards better energy efficiency.

How is the EnPI result of a facility evaluated?

1. Comparison with goals: EnPI 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 EnPI is trend analysis over time. A rising EnPI result may indicate a decrease in energy efficiency, which may require optimization measures, while a decreasing result suggests improved efficiency.

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

4. Absolute and relative values: EnPI 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 e-KPI 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 e-KPI 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.

What are the key factors influencing EnPI?

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. Here, more on comparig energy consuption.

3. CO2 emissions: The EKPI indicator can also include the aspect of carbon dioxide emissions as an environmental metric. Here, more about the future of the industry in the New Realities.

The best time intervals for assessing EnPI changes?

Monitoring EnPI can be conducted long-term (annually) or short-term (monthly/weekly). Shorter intervals allow for better management of trends and anomalies. In practice, EnPI evaluations occur over multiple time frames, as this enables a better understanding of 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 EnPI and make informed decisions both in the short and long term.

Summary.

In conclusion, EnPI is more than just numbers — it’s a GPS for the energy landscape of a modern company. By tracking every kilowatt, we uncover areas where optimization can lead to real savings. Comparing results with others sparks healthy competition, which does wonders for engagement. After all, who wouldn’t want to be the leader in the race for energy efficiency?
