Question
In IPMVP, routine adjustments correct regular variations (weather, occupancy, production) via regression or factor, while non-routine adjustments (NRA) handle unplanned static changes (added floor area, extra shift, refurbishment) that occur between baseline and reporting periods.
Answer
True
The distinction is critical: routine adjustments use variables known in advance (weather, occupancy) and are embedded in the baseline function; non-routine adjustments handle unexpected events that alter the comparison conditions (for example adding a third production shift causes roughly +33 % consumption that has nothing to do with the ECM). EVO publishes a dedicated NRE/NRA guide. Without NRA, the ECM gets blamed (or credited) for savings it did not cause.
Preparation tip
Set up an NRA log on day one of the reporting period — capturing changes as they happen is far easier than reconstructing them 12 months later.
