OpenStudio Application Interface Guide

This section contains an overview of the OpenStudio Application.

The OpenStudio Quick Start Guide provides an introduction to the interface for the Plug-in and the OpenStudio application. It also provides guidance on the basic workflow.

Above: This video demonstrates the new Spaces tab and the redesigned Facilities and Site tab from version 1.9.0.


Overview

The tabs on the left that move vertically are ordered in a suggested workflow.

Overview

Above: Overview of the OpenStudio Application Interface.


Sub-tabs

Sub-tabs are designed to move from more general categories on the left to more specific on the right. On the constructions tab, the sub-tabs are "Construction Sets", "Constructions", and "Materials." If you are not building your own materials and constructions you may not need to go to the "Materials" sub-tab.


Right Panel

The right panel provides access to items in the library or in your model, as well as the ability to edit some of these items.

  • "My Model" displays items that are part of your model already.

  • "Library" includes components and measures that come with the application or are downloaded from the Building Component Library (BCL)

  • "Edit" allows you to select certain components and edit the settings for that component. It is used in the HVAC tab to edit component settings, assign thermal zones to loops, and to add plenums.

Edit Tab

Above: Edit settings on some objects in the edit panel.


Left Panel Bottom

Add Add New Item allows the user to add a new component to the interface. Sometimes the type of item added depends on the selection in the left panel.

Add Example

Above: On the "Utility Bill" sub-tab, select the type of bill you want to add before hitting the add button.

Duplicate Duplicate a selected object with this button.

Delete Delete a selected object with this button.

Purge Purge unused objects with this button.


Adding Objects from the Library

To add items from the library, select the "Library" tab on the right panel and find the item you want to add to the model. Select that item and drag and drop it in into the correct drop zone. Drop zones are surrounded by a dotted line and are programmed to only accept items that will work for that field.

Grid View and Multi-edit: Thermal Zones, Space Types, and Refrigeration

Earlier releases have included a grid view for the refrigeration section in the HVAC tab. Now you can edit thermal zones and space types in a grid view. This makes it easier to view all your zones and space types at once and compare settings. By selecting the buttons across the top you can select the fields you would like to see and edit.

Grid Image

Above: The grid view provides a spreadsheet style layout. Click on the image to view a larger version.

View this video to see multi-edit in action.

Drag components and schedules into the grid view. Most items on the grid can be inspected in the right panel "Edit" tab, except schedules. A yellow highlight indicates the item you have selected in the grid. When you start editing the item in the "Edit" tab the highlight will disappear indicating that the focus is now on editing the item.

Select the check box in the top of the column if you want to view that column in the "Custom" category.

Drag components and schedules into the grid view. Most items on the grid can be inspected in the right panel "Edit" tab, except schedules. To edit or view schedules go to the schedules tab. Use the delete in the "Edit" panel to remove a component from the grid.

Click on the color box on the "General" button to change the rendering color of the space type. This will change the rendering color in the SketchUp Plug-in as well.

You can use the Multi-edit feature on individual columns (as shown below) or on whole rows by selecting a row or rows and hitting the "2X" button on the bottom left to duplicate those rows.

Above: The steps for using the multi-edit function are shown above.

File Menu

If you launch the OpenStudio application from the SketchUp Plug-in, your open file will automatically open in the application. But to save the file or open a new file, select file open from the menu.

When you save an OSM model in the OpenStudio Application or the SketchUp Plug-in a folder is saved next to the OSM file. This folder contains external resources such as the weather file, scripts, and simulation results.

Load Library is also a very important feature. This allows you to load building component libraries for specific building types. These libraries are the same as those used in the SketchUp Plug-in templates.

File Menu

Above: The file menu contains the new, open, revert, save, import, and export functions.


Preferences Menu

The Units menu lets you switch between SI and IP units. This affects both input fields and output data on the results tab. It does not currently affect standard EnergyPlus output files.

The SketchUp Plug-in has access to this as well under Plugins->OpenStudio->Preferences.

Scan for Tools will look for Radiance, Ruby, and EnergyPlus installations. If you install those applications prior to installing OpenStudio this shouldn't be necessary.

Preferences Menu

Above: The preferences menu contains the units, measure directory, and tool location options.


Components & Measures Menu

Components & Measures Menu

Above: This menu item allows you to run one measure on you model.

Apply Measures Now

You can apply measures to your model at any time by going to the "Components and Measures" menu and selecting the "Apply Measures Now" option.

This will open a dialog that allows you to choose a measure from the library to apply, go to BCL to find a measure to apply, or even write your own measure and test it.

Once you select a measure you may edit the measure inputs on the right side of the dialog. Hit apply measure to start.

Apply Measure Now

Above: This menu item allows you to run one measure on your model.

Find Measures and Find Components

The BCL window gives you access to an online repository of building energy modeling data called the Building Component Library. Although you can access the BCL website on its own, OpenStudio has integrated access to the BCL from within the application. You can access this through the "Components & Measures" menu.

The first time you open this window you will be prompted for an API key, unless you have already used BCL functionality in the SketchUp Plug-in. Instructions for finding your API Key are in the "Getting Started" section.

BCL Window

Above: This window gives you access to the online BCL to download measures or components.
