About the Rollup Parameter
The meaning of the rollup parameter depends on the type of data that it represents. For example, data that represents a “consumption” type value (i.e., Electric Consumption or Gas Consumption) will be added, continually over the interval period. On the other hand, data that represents a “demand” type value (i.e., Electric Demand or Gas Demand) will use the peak value over the rollup interval range (not the average). Therefore, the point that is plotted on your report graph may represent a “total” for the interval period (i.e., total consumption for every 15 minute interval) or your point may represent an “average” for the interval period (i.e., average hourly temperature). If it is used for demand, it represents the peak for the interval period. The following list summarizes how the different types of data are represented by the rollup parameter:
- Consumption type values are added (total).
- Demand type values use the max (peak).
- Outside air temperature or other type values use the average.
Most reports can specify a minimum interval as low as 15 minutes. The Equipment Operation report, however, may specify a 1 minute interval, if the information is being logged in the workstation at that frequency.
For information about report - specific parameters, including the ones in the following chart, refer to the specific report descriptions.
