Question 1 of 30

As the newly appointed energy manager at \"Stellar Manufacturing,\" a large-scale textile production facility, you are tasked with establishing energy baselines and performance indicators (EnPIs) according to ISO 50004:2020. Stellar Manufacturing operates 24/7, and its energy consumption is heavily influenced by both production volume and seasonal weather variations, particularly temperature fluctuations that affect heating and cooling demands. After collecting initial data, you observe a significant increase in energy consumption during a particularly cold winter, despite maintaining consistent production levels. Which of the following approaches would be MOST appropriate to ensure a fair and accurate assessment of Stellar Manufacturing\'s energy performance improvements over time, aligning with the principles outlined in ISO 50004:2020?

Normalize the energy consumption data to account for the degree days during the baseline period and subsequent periods, adjusting for temperature variations to provide a more accurate comparison of energy performance.
Exclude the data from the unusually cold winter period from the baseline calculation to avoid skewing the results and focus solely on periods with average weather conditions.
Compare the total energy consumption across different periods without any adjustments, as the overall trend will eventually reflect the impact of energy efficiency measures.
Implement a fixed percentage reduction target for energy consumption each year, regardless of external factors or production levels, to demonstrate a commitment to energy efficiency.
