Energy Impacts Tab

Viewing Energy Impacts

To view the energy impacts associated with a measure, select the measure in the measure list and double-click on the row or press the "View Energy Impacts" button at the top of the list. Some measures have multiple sets of energy impacts associated with the same measure definitions, defined by the measure Qualifier. For these measures, a pull-down control will appear above the measure list with all possible Qualifiers. Select the qualifier of interest before pressing the "View Energy Impacts" button.

The Energy Impacts screen initially contains two sections: details of one energy impact record at the top and a table with a list of all the applicability combinations at the bottom of the screen. Similar to the Measure screen, you choose a particular energy impact by selecting a row from the Energy Impacts List. Note: you can use the Up and down buttons located near the top-right of the screen to see more or less information about the selected energy impact.

You can customize the table that lists the energy impacts in a number of ways:

  • Point to the edge of one of the column headers and then use the left mouse button to drag the columns to the desired widths.
  • Click on a column header with the left mouse button and drag the entire column to a new position.
  • Right-click on the table and choose "Select Table Columns". A list of all available energy impact fields will be displayed; click on the fields you want to add or remove.
READI will remember your table settings the next time you start the program. To reset the table to the default settings, right-click on the table and choose "Reset Table Column Display". This will cause READI to forget your current settings and the next time you start READI the default formatting will be used.

Using the Energy Impacts Graph

Pressing the Display Graph button (top-right of screen) launches the Energy Impacts graph. The Energy Impacts graph has a number of options and features that allow you to quickly review and compare the energy impacts for the selected measure.

Graph Options:

  • X-axis: sets the x-axis of the graph to either all applicable locations or all applicable building types. If "Location" is chosen, the left and right arrows or pull-down list can be used to choose the Building type. Similarly, if "Bldg Type" is chosen, the arrows and pull-down list are used to choose the location.
  • UES Values: the main graph series will be set to the selected energy type with the units described on the graph's left axis.
  • Baseline: sets the main graph series to savings based on comparison with "Pre-Existing" technology or the "Code/Standard Replacement" technology.
  • Savings Type: sets the main graph series to whole-building or end-use impacts. Note that not all measures have end-use impacts.
  • Y-axis options: when "Fix the Y-axis" is checked, the graph will use the highest and lowest chart values encounted since the chart was "reloaded". This allows the relative savings between building types, climate zones or even measures to be compared. If "Y-axis Zero" is checked as well, the graph will include the zero impact value on the Y-axis scale.

Chart Series:

  • IOU: Select the series to be plotted on the graph. Keep in mind that the "All" series option will display the results for energy impacts where IOU = "All"; this option does not force the display of all series.
  • Building Vintage: Turn on or off the Existing and New building vintage results. If more than one existing vintage is included in the table of energy imapcts the specific existing vintage can be selected from the pull-down list below this control.
  • HVAC Type: If more than one HVAC type is included in the table of energy imapcts the specific HVAC type can be selected from this pull-down list.
Press the pin icon at the top of the chart to make the chart stay on top of READI. When you return to the Measures tab, selecting new measures will update the graph but will not take you to the Energy Impacts tab. This allows for a quick review of multiple measures without switching between tabs.

Downloading Energy Impacts to your computer

As with the other tables, you can download the results associated with the Energy Impact table by right-clicking and selecting the download option. This process will download results for a single measure. For more options on downloading energy impact data, see the "Save Tables" help tab.
