With reference to Column 4 of the Energy Assessment Worksheet, F-630-001 a simplest method of assessing / quantifying the significance of energy use / consumption is to use the letters H or M or L to indicate whether the Severity and Occurrence are high or medium or low. H = High M = Medium L = Low In general: When both Severity and Occurrence are High, the energy use is significant, and the process step requires improvement action When one or both the severity and the likelihood are indicated as medium, additional reviews are required to identify existing conditions that reduce or eliminate the energy use.

Below is a method to quantify the energy assessment. S = Severity of the Outcome High = 10, 9, 8 Medium = 7, 6, 5, 4 Low = 3, 2, 1 L = Likelihood of the Occurrence High = 10, 9, 8 Medium = 7, 6, 5, 4 Low = 3, 2, 1 (L x S) = Significance of energy use, High = 100 to 50 range Medium = 49 to 16 range Low = 15 to 1 range

Significance of Use and Consumption A variation in the method to analyze the Severity and Likelihood and assess the significance or energy performance associated with the process step.
