Baseline configuration

Both the Average Profile and Load Duration Reports may use data values within the trend. This baseline makes it possible to compare a current data value against itself at a previous period of time. For example you set a baseline to compare Main kWh for last week with Main kWh for the same week in the previous year.

You establish a baseline by enabling the check box under Baseline on the Report Editor. To configure baseline details, you click the Show Details button (Image).

To open this window, click the down-arrow icon next to Custom Period. Once you select a node group, the text indicates the node group name, such as “Building 1/1 Month Prior” or “Building 1/Custom Period.” The screen capture shows the configuration used to produce the Baseline properties on an Average Profile Report above.

Property Value Description
Select Node Group drop-down list (defaults to the first node group) Selects the node group to use for baseline data. You select one node group at a time to establish the baseline.
Baseline Color Color chooser Selects a series color for the baseline data.
Baseline Time Range, Custom Period drop-down list Calculates the baseline in relationship to the other Baseline Time Range properties. Refer to The baseline calculations.
Baseline Time Range, Start time date and 12-hr time selector Selects what time of day to establish the baseline.

These values are only valid if the Custom Period option is in use. Otherwise, the framework automatically calculates the start date and time.

Baseline Time Range, End time check box check box (defaults to disabled, that is, no check mark) Enables and disables the ability to edit the End time property. The default automatically calculates the end date.

These values are only valid if the Custom Period option is in use. Otherwise, the framework automatically calculates the end date and time.

Baseline Time Range, End time date and 12-hr time selector Selects the time of day to stop the collecting of baseline data.
Align day of week check box (defaults to disabled, that is, no check mark if Custom Period is in use, otherwise, it defaults to enabled) Plays a critical role in the automatic calculation of the start and end dates and times for the selected baseline. Refer to The baseline calculations.

The baseline calculations

All baseline calculations reference the Reporting Period as defined in the Report Editor.

If Custom Period is selected for Baseline Time Range, the framework activates the Start time properties and provides optional End time properties. If no End time is defined, the framework uses the selected time range (the main time range) to determine when the baseline period ends. If End time is enabled and a time selected, the framework uses this date and time to end the baseline period.

When you select a Baseline Time Range, such as 1 Week prior or 1 Month prior, the framework calculates the baseline start and end dates and times based on the selected time range and the Align day of week property. If Align day of week is disabled, the framework subtracts the time range from both start and end date times of the selected range.

If the Align day of week is enabled, the framework takes the start date of the selected time range as a reference and calculates the same day of the week in the previous week or month. For example, if the start date is the second Wednesday of this month and the baseline period is 1 Month Prior, the baseline starts the second Wednesday of previous month. The framework calculates the end date and time by adding the duration of the time range to the calculated baseline start date and time.

When 1 Year prior is selected for Baseline Time Range, the framework calculates the baseline start and end dates based on the selected time range and the Align day of week property. If the Align day of week is disabled, the framework subtracts one year from both start and end date times of the selected time range.

If the Align day of week option is enabled, the framework takes the start date of the selected time range as a reference and calculates the same day of the week in the previous year. For example, if the start date is the Wednesday in the eighth week of the year, the baseline starts the Wednesday in the eighth week of the previous year. The framework calculates the end date and time by adding the duration of the time range to the calculated baseline start date and time.
