For instance, anomalies on single sites can be analysed; on Evolution you can compare two different individual days to see if an increase occurred over the full day or within a specific time period (useful also when looking at usage before and after works have been undertaken).  Alternatively you can overlay different utilities to check when a sites gas usage say decreases, whether the electricity increases at the same time.

On a multiple site level, you have the option to see immediately where one of your sites is using more energy than another similar site.  This function can also be used to compare the consumption levels of similar equipment which has been submetered (for example air conditioning) at different sites.
