HERS-ST Highway Economic Requirements System - State Version: User's Guide
Chapter 5 Starting the Software
This chapter addresses logging on to the system and initiating the program. Users will learn about the application environment and the basic skills that are needed to maneuver through the system.
The logon window will not appear if HERS-ST already has enough information to connect to the database.
After you have installed the software, you can open HERS-ST from your Start Menu by selecting Start / Programs / HERS-ST / HERS-ST.
At the Logon screen (shown in Figure 5-1), you can select a HERS-ST database file by clicking the Database button. To logon, type your user name and click the OK button. No password is required to logon to HERS-ST.
Figure 5-1. Logon Screen for HERS-ST.
The user name will be used to identify the individual who created or edited data within the software.
After you complete your logon, the next screen you see will be the Workset Browser (Figure 5-2). You use the Workset Browser to navigate at the highest level in the application. The Existing tab allows you to select or delete an existing Workset from the database and select the other data inputs as previously described in Chapter 2. The New tab allows you to name and build a new Workset. A Workset is the highest level of organization used within HERS-ST.
Deleting a Workset is permanent. Once a Workset is deleted, it cannot be recovered.
To ensure effective use of the application, it is important that you understand Worksets, one of the primary concepts you will work with when you use HERSST. You will learn more in Chapters 6 and 7 about how to build a Workset, but it is important to master this concept before you begin running analyses.
Figure 5-2. Workset Browser.
In HERS-ST, you organize your work into "Worksets." A typical Workset addresses one or more tasks you are using HERS-ST to explore. Each Workset provides the framework you need to generate and collect the results of the analysis. The three primary categories of this framework are Settings, Results, and Reports (see Figure 5-3).
You will collect the information needed to conduct the HERS-ST analysis in the Workset Settings. HERS-ST will process the analysis and place a copy of the settings used for that specific analysis and the outputs of that analysis in the Workset Results area. In HERS-ST, this combination of settings and output results is a Scenario. HERS-ST also calls the outputs of the analysis a run. A Scenario with at least one run (or set of outputs) is always created. If you perform the analysis for a single value, HERS-ST generates output for a single run. When you perform an analysis over a range of values, HERS-ST generates multiple runs (or sets of outputs). Reports can then be generated to visualize the result data.
The application environment (illustrated in Figure 5-3) consists of two primary areas: the Workset tree and the workspace area. The Workset tree on the left side of the window displays the three tabs of the items that make up the Workset: Settings, Results, and Reports. You can right-click on the branches of the tree to display a popup menu that will allow you to perform functions which include adding, importing, or displaying individual items. The workspace area displays the windows used to review and/or revise the various Workset items.
Figure 5-3. HERS-ST Application Window.
You can modify the HERS-ST application environment to meet your specific user needs. You access these options by selecting Tools/Options from the menu and navigating through the tabs (Figure 5-4). Select the option by clicking on the button. You may want to work with the application for a while before you modify the default settings of the options. Additional information on customizing the application environment can be found in Chapter 11.

The Database Manager (Figure 5-5) provides you with a variety of tools to maintain and manage the database files used by the HERS-ST environment. The list of existing databases shows all of the Microsoft Access® 2000 (MDB) files that exist in the database directory. The directory is determined by the active database selected when you originally logged on or as selected in the environmental options settings.
The active database is designated by the pointer icon in the left margin of the database list.

- View Contents. This option displays all of the Settings items in the selected database. When you display the contents of a database, it will be displayed in bold font in the existing database list.
- Rename. This option allows you to rename the selected database. You cannot rename the active database while a Workset is open.
- Copy Database. This option copies the selected database.
- Create New. This option creates a new blank HERS-ST database file.
- Delete. This option deletes the selected database. The active database cannot be deleted.
- Compact and Repair. This option performs maintenance operations on the selected database file. You should periodically perform this maintenance on your database files, especially after deleting data. A backup of the original database is created and stored in the same directory. You cannot use this feature on the active database while a Workset is open.
You can copy individual Data and Settings items from one database to another by displaying the contents of the source database and then dragging the items from the tree to your destination database. A list of existing Worksets from the destination database will be displayed and you must select which Workset the item is to be copied into. You cannot copy items into a workset while it is open.
