The pop-up dialog box has nine (9) main feature areas that allow users to adjust global settings for the Simergy Building Energy Models (BEMs):
These buttons will be available at the bottom of most of the feature areas:
Allows the user to revert back to the defaults that are installed with Simergy.
Allows the user to revert back to the defaults that they have saved as "My Defaults".
Allows the user to save any changes made as "My Defaults. Therefore when they open this dialog in another Simergy file those selections will appear versus the standard set that are included in Simergy.
Allows the user to save the current settings, but for the current Simergy file.
Closes the dialog box. If the user makes changes that have not been saved then they will be prompted to save or ignore changes prior to being closing the dialog box.
Controls all the units of measure and rounding precision for each unit that is displayed in the Simergy interface.
Simergy has the capability to display both Imperial (IP) and SI units, and the user can change the units of a model at any time by selecting File/Options and changing the User Interface Measure Units. The different Simergy workspaces, including Results Visualization conform to this global parameter. So, if a user changes the units it will change in all the Simergy workspaces.
When a user starts a new model in Simergy, IP units is the default.
When a user opens an existing Simergy model the units will be the units that the model was saved with previously. Example - if the project was last saved with SI units, when a user goes back to open that file, SI units will be the active units.
By selecting the radio buttons the user can toggle between SI units for all the units of measure or Imperial Units. The default is Imperial units, but by selecting SI Units all the units of measure in the table change to SI units, however the Rounding Precision values remain the same.
The table displays all the units of measure included in Simergy, the Imperial Unit default selection (bold) and other options, the SI Unit default selection (bold) and other options, and the number of decimal points displayed for the unit (Rounding Precision).

For any unit of measure the user can enter a specific value in the cell for the number of decimal places that unit of measure will display for Simergy.
Note: the default values for each unit of measure are included in the table above.
Controls all of the model measure units that are utilized by Simergy and EnergyPlus to do the simulation calculations.
The table displays the model measure units included in Simergy, which are the basis for the calculations that the EnergyPlus analysis engine develops during the simulation. The table shows the model measure units and the default units. In a number of cases the user cannot change the units because the EnergyPlus analysis engine currently requires this unit type to effectively develop the simulation. The User Interface Measure Unit settings allow the user to adjust the units representation within the Simergy interface and results.

The language the interface can be selected from the available options. Currently the available languages are English, French and Spanish. English is the default language.
Functions as a shadow-copy of your project while the user is working in a Simergy session. During the session the shadow-copy of the Simergy file is saved for the time increment selected by the user in C:\Users\Public\Simergy\AutoSave. When a Simergy Session is closed and the user has successfully closed out that session without problems, the shadow-copy of the Simergy file is deleted from the AutoSave folder. If the session ends abnormally, the shadow-copy of the Simergy file remains and the user can recover the file by going to the AutoSave folder and opening the Simergy shadow-copy file.
A checkbox allowing the user to turn ON the auto-save feature. By default it is turned OFF.
The user can directly input and/or select a time increment from the drop-down list to set the Auto-save time increment that will be utilized
The user can choose whether utility costs are set using decimal values or variable names
The user can enable T24 code checking here.
Users can choose if property warnings will pop up and if only simple properties will be shown.
One main source library (Library.siml) is installed with Simergy version 1. A maximum of (5) library option selections will be available to the user to select from within the drop down at any one time, which include the up to four libraries that can be defined and the library associated with the project model. When the user makes a selection the "current library" changes and the library entities and templates that are available to the user change across the entire interface.
Related Topics - Source Library Content; How is a Source Library different from a Library Entry?; How can I change the Source Library?
Simergy only allows for four libraries to be selected and active at one time. The order of the four active libraries, which defines how they appear in the drop down list, can be selected at the bottom of the dialog box. The available libraries that are listed above are the ones that will be available for selection in the Selected Libraries drop down list. The user can change the name of the Library by editing the name in the Library File Name field. Once the appropriate changes are made the user should hit Save. If there is a desire to get back to the defaults the user can select Load Defaults or they can establish a new set of defaults by selecting Save As Defaults.
If the user wants to change the library options that are available in the Select Library drop down list they will need to go to File/Options to gain access to the dialog box shown, which defaults to the Library/Template Preferences. The other options are listed in the left column, and the Project Options topic that appears initially depends on what the user’s location in the user interface is when they go to File/Options.
Listed at the top table in a format of each library on a single row. The local path of the library is listed.
Establishes the order that the available libraries will appear on the drop down list. The default order is the same order that they are listed in the Available Libraries table above. The user can change the order by selecting the drop down list icon next to the desired order number. The list of available libraries will appear and the user can select a different library to place in that order slot on the list. When a library is selected the defaut Library File Name associated with it will appear in that column.
The selection of the Source Library determines what library entities and templates that the user has available. The user can change the "Current Source Library" by either selecting a different Library from the drop down list on the lower right side edge control on the workspaces or by going to File/Options.
Here the user can change the default settings for the Create/Edit Buildings workspace
Here the user can view the source, version, installation location and output file location of the simulation engines.
Here the user can change the default settings for various properties in the Standards tab.
