What does "time weighted" mean? Follow

Metrics in Portfolio Manager are calculated based on your energy data and Property Use Details (hours of operation, number of computers, etc.) over a specific 12-month period. However, Property Use Details can change over the course of the 12 months, so we time-weight them so they are appropriately attributed. For example, say you have 100 computers for the first half of the year, but increased it to 150 computers for the second half of the year. The “time weighted” value for Number of Computers is 125.5 for the year.

Because we use time-weighted metrics, you may see a value that doesn't look familiar (you never actually had 125 computers) or values with decimals for Use Details that can't possibly have a decimal (22.5 Workers).
