No, the metrics for a campus (parent) property do not automatically “roll up” information from it's child properties. Metric calculations for a parent property with child buildings will only use data from meters that are directly associated to the parent property. The reason the meters are not rolled up is because meters on the child buildings may be “sub-meters” of energy represented on a master meter at the campus level. Therefore, simply rolling everything up might double count some energy use.
If you would like to associate the same meter(s) to both a parent property and its child, you must add the meters to the individual child property first, and then associate the meters to both the parent and child property.
