What does "Adjusted to Current Year" mean? Follow

Portfolio Manager has six metrics that use the term “Adjusted to Current Year”:

  • Site Energy Use - Adjusted to Current Year
  • Source Energy Use - Adjusted to Current Year
  • Site EUI - Adjusted to Current Year
  • Source EUI - Adjusted to Current Year
  • Water/Wastewater Site EUI - Adjusted to Current Year
  • Water/Wastewater Source EUI - Adjusted to Current Year

This metric allows you to compare a previous year’s energy use with the current year’s energy use, by adjusting for weather and other property use details (number of workers, number of computers, etc.).  This allows for an “apples to apples” comparison. For example, say you want to compare this year with 5 years ago when you initiated a major energy efficiency upgrade. But, 5 years ago there was a really cold winter and your staff was 20% larger, which caused increased energy use. The “Adjusted to Current Year” metrics will convert the energy use from the earlier year into the current year’s terms for an accurate comparison to the current year.

Another way to think about this is in terms of dollars. Say you are wondering what a house cost in the 1950’s compared to today. If the average home was $10,000 in 1950, you still wouldn’t know how that compared to an average house price of today. So, you would adjust the $10,000 to “the current year” (2014’s money) to compare how the average home price changed over time.
