Known Issues

The following are issues known at the time of publication of these
release notes. Please contact [email protected] if you require
further assistance.

Known Issues Common to All Platforms

OpenStudio SketchUp Plug-In

• If you use copy multiple on group-level OpenStudio objects, you will
  get one extra copy. The extra group is created by the first
  copy-and-paste operation and is not removed when the copy multiple
  occurs. To address this, after you perform a copy multiple procedure
  on groups or spaces, press delete. The objects you need to delete
  should already be selected. If you are copying loose surfaces such
  as windows, there are no problems, as SketchUp will merge equivalent
  surfaces. [issue
  #28]
• Using SketchUp’s undo operation on OpenStudio model elements may
  produce unexpected results. [issues
  #54 and
  #150]
• SKP and OSM link is not maintained when files are relocated.
  However, you can manually re-establish that link. When opening a
  SketchUp file, launch SketchUp and then open the SketchUp file. If
  that doesn’t work you can also directly load the OSM file, bypassing
  the SKP file. [issue
  #409]
• It is possible for the OpenStudio plug-in to conflict with other
  SketchUp plug-ins. If you suspect this is a problem, try testing
  with other plug-ins disabled, or contact [email protected] for
  assistance. [issue
  #26]
• Using “Intersect” in the surface matching dialog can result in a
  crash or unexpected results. This is more common with models that
  were imported from other CAD formats at some point in the workflow.
  It is a good idea to save prior to using this to avoid any loss of
  data. This is related to an underlying SketchUp bug. [issue
  #168]
• “Project Loose Geometry” can crash SketchUp. It is a good idea to
  save prior to using this to avoid any loss of data. [issue
  #484]
• Adjacent stacked spaces in same zones may result in incorrect area
  and likely loads as well. [issue
  #561]
• Using AutoSave in SketchUp can overwrite changes made in OS app if
  the file is open in both locations. [issue
  #899]

If your OpenStudio model causes a crash of SketchUp or has unexpected
behavior, please forward it to [email protected] with a detailed
description of the problem along with the steps that produced the issue.
Please also include the directory that has the same name as the OSM
file. You can attach it as a zip file.

OpenStudio Application

• EnergyPlus 8.2 no longer provides simulation output to standard
  output during simulation. [issue #1359]
• Similar thermostats assigned in the SketchUp Plug-in are shared
  across thermal zones in the OpenStudio application. Changing or
  turning off one will do the same to others. [issue
  #123]
• The view does not always refresh correctly when you delete a
  material from a construction. If you still see a material after
  clicking the “x”, switch away from and back to the object to refresh
  the view. [issue
  #196]
• OS App Schedule Editor allows entering values outside of type
  limits. [issue
  #531]
• All drop zones under Water Use Equipment Definitions doesn't enforce
  schedule types. [issue
  #532]
• Some HVAC components in OpenStudio are missing from the HVAC Library
  (e.g. Fan:OnOff). [issue
  #599]
• Several objects in OpenStudio appear to accept erroneous input
  values, but seems like it is just displaying the erroneous value and
  not storing it. [issue
  #656]
• Attempting to autosize a WaterHeater will result in an error. [issue
  #669]
• Entering an invalid date on the Utility Bills subtab crashes
  OpenStudio. [issue
  #739]
• To enable set point schedule drop zones on the Thermal Zones tab,
  you need to first turn on the thermostat.
• The Site / Utility Rates subtab in the workflow is marked as “coming
  soon,” and will be completed in an upcoming release of OpenStudio.
• The default reporting measures used for the results tab show results
  in IP units, and do not react to changes in the user’s unit
  preferences. That will be addressed in future versions of
  OpenStudio. The measure can be altered to show SI units instead.
• It is not possible to choose or define a refrigeration case (or
  walkin) re-stocking schedule in the “Grid” view or the “Layout”
  view; the drop down list is blank. [issue
  #966]
• Report web views may load slower than they use to with the update to
  Qt5. [issue
  #1211]
• With larger models, GridView’s performance may slow. Performance
  improvements are currently being implemented and will be available
  soon in a minor release.

OpenStudio ParametricAnalysisTool

• NOTE: when using cloud service, please make sure to stop the cloud
  using the cloud button in PAT when your simulation session is done,
  and after you have downloaded all of the detailed results you want.
  You are also strongly encouraged to go to the AWS Management Console
  to confirm that all instances are terminated. If they are not
  terminated, you will need to manually terminate them from the
  console. Refer to the OpenStudio
  documentation for details about running
  simulations on the cloud.
• EnergyPlus 8.2 no longer provides simulation output to standard
  output during simulation. [issue #1359]
• Daylighting control object variables can’t be requested in the
  output variables tab. [issue
  #355]
• Adding a design alternative using measure groups will remove any
  design alternatives made from external files. However, you can add a
  design alternative made from external files without losing design
  alternatives made from measure groups. [issue
  #369]
• Always Run measures are applied to externally constructed design
  alternatives. This may result in unexpected results or errors.
  [issue #369]
• Windows users may experience problems when starting cloud resources
  through PAT due to a bug in net-ssh,
  https://github.com/net-ssh/net-ssh/issues/180.  If the user has
  the pageant.exe program running, killing that program through the
  task manager may resolve the issue.

OpenStudio ResultsViewer

• Alias changes do not update in table view until the data are read in
  again. [issue #25]
• Re-arranged column order doesn't stick on next launch. [issue
  #30]

OpenStudio RunManager

• EnergyPlus ForwardTranslator errors do not appear in the RunManager
  GUI elements. [issue
  #181]

OpenStudio Platform, Including SWIG Bindings

• IdfObject::getQuantity and IdfObject::setQuantity functionality is
  not comprehensive. The quantity getters and setters for fields whose
  units are “BasedOnField AX” are not expected to work at the
  IdfObject level, but are to be handled only for OS: prefixed objects
  by the specific interfaces of classes derived from ModelObject.
• The default naming scheme of WorkspaceObject (base class for
  ModelObject, etc.) sometimes results in undesired name clashes when
  transferring objects between models, including in the EnergyPlus
  translators. Therefore, some objects may be unexpectedly renamed or
  copied.
• OpenStudio::Model::ComponentVector objects may be inaccessible from
  the Ruby bindings. [issue
  #239]
• If schedule type limits fields are not set properly, OS will not
  give error but also will not hook up affected schedules. [issue
  #967]
• There is no default construction for adiabatic surfaces. [issue
  #974]
• Cloning a building disconnects spaces from thermal zones. [issue
  #980]
• The simulation fails if ground preprocessor boundary conditions are
  used. [issue
  #1127]

Known Issues Specific to OS X

• The SketchUp Plug-in toolbar tooltips do not work correctly on OS X
  if you have made your toolbars horizontal. The tooltips never show
  on OS X in the status bar. The button state may also be incorrect.
  This is a bug in SketchUp versus the plug-in. [issue
  #45]

Overview

This OpenStudio 1.5.0 release updates many OpenStudio dependencies. The biggest of these is an upgrade from Ruby 1.8 to Ruby 2.0. This update allows OpenStudio to leverage upon the improvements available in Ruby 2.0, and provides compatibility with SketchUp 2014. However, this update also means that OpenStudio will no longer be compatible with SketchUp 2013 or SketchUp 8. C++ developers will notice upgrades to Qt 5 and Boost 1.55, as well as the inclusion of C++11 features in OpenStudio source code.

OpenStudio for OS X is now built with the 10.9 SDK for Ruby 2.0 support, making Mavericks the primary Apple platform, and Ubuntu 12 support has been removed in favor of Ubuntu 14.04 LTS. Windows platform support remains the same, with Windows 7 – 8.1 compatibility.

This OpenStudio 1.5.0 release also includes several improvements to measures. Reporting measures can now request output variables from EnergyPlus to ensure that they have the data they need to create plots or make reports. Additionally, units and descriptions can now be added to measure arguments.

The OpenStudio C++ SDK documentation has been significantly improved, which includes a search feature and links between all Doxygen directories. Updated C++ and Ruby coding standards can be found on the GitHub wiki.

Other notable improvements:

• Previously available for Refrigeration Walk Ins and Refrigeration Cases, GridView (a grid-style interface providing detailed component views) has now been applied to the Space Types tab, as well as the Thermal Zones tab. These GridView-enabled tabs now allow practitioners to view and modify numerous Space Types (or Thermal Zones) and their objects, simultaneously.
• Multiple performance improvements and bug fixes.

Overview

This OpenStudio 1.4.0 release is the first major release compatible with EnergyPlus 8.1. OpenStudio 1.4.0 is also the last release to be built on Ruby 1.8. Therefore, this is the last release for which the OpenStudio SketchUp Plug-in will be compatible with SketchUp 8 and SketchUp 2013. The OpenStudio SketchUp Plug-in will only be compatible with SketchUp 2014 and above in future releases of OpenStudio. The most significant new feature in OpenStudio 1.4.0 is the ability to apply measures directly to the current model in the OpenStudio Application.

Known Issues

The following are issues known at the time of publication of these release notes. Please contact [email protected] if you require further assistance.

Known Issues Common to All Platforms

OpenStudio SketchUp Plug-in

• If you use copy multiple on group-level OpenStudio objects, you will get one extra copy. The extra group is created by the first copy-and-paste operation and is not removed when the copy multiple occurs. To address this, after you perform a copy multiple procedure on groups or spaces, press delete. The objects you need to delete should already be selected. If you are copying loose surfaces such as windows, there are no problems, as SketchUp will merge equivalent surfaces. [issue #28]
• Using SketchUp's undo operation on OpenStudio model elements may produce unexpected results. [issues #54 and #150]
• SKP and OSM link is not maintained when files are relocated. However, you can manually re-establish that link. When opening a SketchUp file, launch SketchUp and then open the SketchUp file. If that doesn't work you can also directly load the OSM file, bypassing the SKP file. [issue #409]
• It is possible for the OpenStudio plug-in to conflict with other SketchUp plug-ins. If you suspect this is a problem, try testing with other plug-ins disabled, or contact [email protected] for assistance. [issue #26]
• Using "Intersect" in the surface matching dialog can result in a crash or unexpected results. This is more common with models that were imported from other CAD formats at some point in the workflow. It is a good idea to save prior to using this to avoid any loss of data. This is related to an underlying SketchUp bug. [issue #168]
• "Project Loose Geometry" can crash SketchUp. It is a good idea to save prior to using this to avoid any loss of data. [issue #484]
• Adjacent stacked spaces in same zones may result in incorrect area and likely loads as well. [issue #561]
• SaveAs in SketchUp corrupts measures in model. To avoid this, only add measures into model after work in SketchUp is done. [issue #754]
• Using AutoSave in SketchUp can overwrite changes made in OS app if the file is open in both locations. [issue #899]

If your OpenStudio model crashes SketchUp or has unexpected behavior please forward it to [email protected] with a description of the problem. Please also include the directory that has the same name as the OSM file. You can attach it as a zip file.

OpenStudio Application

• Similar thermostats assigned in the SketchUp Plug-in are shared across thermal zones in the OpenStudio application. Changing or turning off one will do the same to others. [issue #123]
• The view does not always refresh correctly when you delete a material from a construction. If you still see a material after clicking the "x", switch away from and back to the object to refresh the view. [issue #196]
• Some pull-down lists in simulation settings don't work. [issue #496]
• OS App Schedule Editor allows entering values outside of type limits. [issue #531]
• All drop zones under Water Use Equipment Definitions doesn't enforce schedule types. [issue #532]
• Removing CoilHeatingWater objects can result in orphaned hot water coils. [issue #594]
• Some HVAC components in OpenStudio are missing from the HVAC Library (e.g. Fan:OnOff). [issue #599]
• Several objects in OpenStudio appear to accept erroneous input values, but seems like it is just displaying the erroneous value and not storing it. [issue #656]
• Attempting to autosize a WaterHeater will result in an error. [issue #669]
• Entering an invalid date on the Utility Bills subtab crashes OpenStudio. [issue #739]
• To enable set point schedule drop zones on the Thermal Zones tab, you need to first turn on the thermostat.
• The Site / Utility Rates subtab in the workflow is marked as "coming soon," and will be completed in an upcoming release of OpenStudio.
• The default reporting measures used for the results tab show results in IP units, and do not react to changes in the user's unit preferences. That will be addressed in future versions of OpenStudio. The measure can be altered to show SI units instead.
• It is not possible to choose or define a refrigeration case (or walkin) re-stocking schedule in the "Grid" view or the "Layout" view; the drop down list is blank. [issue #966]
• IDF import brings in but does not hook up design spec outdoor air. [issue #971]

OpenStudio ParametricAnalysisTool

• NOTE: when using cloud service please make sure to stop the cloud using the cloud button in PAT when your simulation session is done, and after you have downloaded all of the detailed results you want. You are also strongly encouraged to go to the AWS Management Console to confirm that all instances are terminated. If they are not terminated, you will need to manually terminate them from the console. We have a sticky post on our forum with best practices for cloud simulation in OpenStudio.
• Daylighting control object variables can't be requested in the output variables tab. [issue #355]
• Adding a design alternative using measure groups will remove any design alternatives made from external files. However, you can add a design alternative made from external files without losing design alternatives made from measure groups. [issue #369]
• Always Run measures are applied to externally constructed design alternatives. This may result in unexpected results or errors. [issue #369]

OpenStudio ResultsViewer

• Alias changes do not update in table view until the data are read in again. [issue #25]
• Re-arranged column order doesn't stick next launch. [issue #30]

OpenStudio RunManager

• EnergyPlus ForwardTranslator errors do not appear in the RunManager GUI elements. [issue #181]

OpenStudio Platform, Including SWIG Bindings

• IdfObject::getQuantity and IdfObject::setQuantity functionality is not comprehensive. The quantity getters and setters for fields whose units are "BasedOnField AX" are not expected to work at the IdfObject level, but are to be handled only for OS: prefixed objects by the specific interfaces of classes derived from ModelObject.
• The default naming scheme of WorkspaceObject (base class for ModelObject, etc.) sometimes results in undesired name clashes when transferring objects between models, including in the EnergyPlus translators. Therefore, some objects may be unexpectedly renamed or copied.
• OpenStudio::Model::ComponentVector objects may be inaccessible from the Ruby bindings. [issue #239]
• If schedule type limits fields are not set properly, OS will not give error but also will not hook up affected schedules. [issue #967]
• There is no default construction for adiabatic surfaces. [issue #974]
• Cloning a building disconnects spaces from thermal zones. [issue #980]

Known Issues Specific to OS X

• The SketchUp Plug-in toolbar tooltips do not work correctly on OS X if you have made your toolbars horizontal. The tooltips never show on OS X in the status bar. The button state may also be incorrect. This is a bug in SketchUp versus the plug-in. [issue #45]
• OpenStudio 1.4 does not support SketchUp 2014 on Mac. This will be addressed in the next release after switching to Ruby 2.0.

Bug Analytics Since Previous Release

• 78 new issues were filed since the 1.3.0 release of OpenStudio (not including opened pull requests).
• 67 issues were closed since the 1.3.0 release of OpenStudio (not including closed pull requests).

Overview

Development for OpenStudio 1.3.0 has two main focuses.

• Development continuation of the refrigeration interface and addition of new refrigeration model objects. This resulted in a new detailed component grid-view of refrigeration systems. The development was carried out with requirements gathering and guidance from practitioners. The new refrigeration objects include contributions from Oak Ridge National Laboratory.
• Enhancements of model objects and methods in support of a collection of Energy Conservation Measures. ECMs were developed to model the recommendations from both the ASHRAE 50% Advanced Energy Design Guide for K-12 Schools, and the ASHRAE 50% Advanced Energy Design Guide for Small to Medium Offices. The ECMs are posted to the Building Component Library (BCL) in conjunction with this OpenStudio release. In addition, ECM supporting material is included with the OpenStudio installer. This includes:
  • A new multi-space type office template.
  • New objects to map constructions and space types to their intended uses.
  • New fenestration methods to describe view and daylight fenestration and skylights.

New Features

OpenStudio Platform 1.3.0

• Improved Standards Data Dictionary (SDD) translation for the California Energy Commission’s CBECC tool.
• Added model objects needed for refrigeration systems – Contributed by Oak Ridge National Laboratory.
  See the OpenStudio’s Contributors page.
• Added HVAC objects from the OpenStudio’s HVAC roadmap.
• Added climate zone tags to the model. This is in support of measures that need to know what climate zone the model is in.
• Added tags to constructions to indicate both the intended surface type and the standards construction type. This is in support of measures that need to know if a construction represents a steel framed or mass wall.
• Added tags to space types to indicate what building type it is intended for, and what specific space type to map it to. This is in support of measure that will apply to only certain types of spaces.
• Added tags to the building object to indicate what building type this model represents. This is also in support of measures that have different behaviors depending upon the building type.
• Created a new multi-space type Office Template to replace the whole building small, medium and large office templates. This allows measures to be applied to specific space types within and office building. It also gives the modeler more control over the ratio of various space types in their model.
• Added new methods to create and apply skylight grids to roofs.
• Added new methods to apply view and daylight glazing in conjunction with exterior shading and interior light shelves.

OpenStudio SketchUp Plug-in 1.3.0

• Updated templates to use the new tags added for constructions and space types. Also, updated infiltration to be on a per exterior wall area vs. air changes per hour.
• Continued to develop experimental user script to import OpenStudio spaces as standard SketchUp groups and to merge SketchUp groups back to OSM files.

OpenStudio Application 1.3.0

• Added customizable pull down menus for standards related tags for climate zones, constructions, space types, and building types. These menus show up in the site, constructions, space types, and facility tabs.
• Updated refrigeration systems in the GUI to support walkin cases.
• Added a detailed component based interface for refrigeration systems interface including cascading systems. A grid style interface has also been added to view multiple refrigerated cases and walkins all in a single view.

Overview

OpenStudio 1.2.0 implements entirely new results visualization. Modelers and developers can create custom reporting measures that show up directly in the OpenStudio application’s results tab. These reporting measures can be shared on the Building Component Library and downloaded directly into the OpenStudio application. This release also features a number of important contributions from external collaborators:

• Oak Ridge National Laboratory added back-end functionality for the modeling of refrigeration systems.
• Penn State University added translation to CONTAM input files.
• Argonne National Laboratory implemented a fast CEN/ISO monthly building energy model calculation.

Also, several new HVAC objects were added, and the initial refrigeration GUI was created within the OpenStudio application’s HVAC systems tab.

New Features

OpenStudio Platform 1.2.0

• Implementation of a fast CEN/ISO monthly building energy model calculation – Contributed by Argonne National Laboratory. See the OpenStudio’s Contributors page.

• To enable set point schedule drop zones on the Thermal Zones tab, you need to first turn on the thermostat.
• The Site / Utility Rates subtab the workflow are marked as “coming soon,” and will be completed in an upcoming release of OpenStudio.
• The default reporting measures used for the results tab show results in IP units, and do not react to changes in the user’s unit preferences. That will be addressed in future versions of OpenStudio. The measure can be altered to show SI units instead.
• Due to the change in the results tab in OpenStudio 1.2.0, if you open an OSM model made with an earlier version of OpenStudio, you will have to re-run the simulation to see results within the OpenStudio application. The previous results still exist without a re-urn if you just want access to the standard EnergyPlus output.
• The HVAC library shows a “Refrigeration Walkin” object, but the GUI doesn’t support it yet. It doesn’t let you drop it into the model. “Refrigeration Case” does work.

OpenStudio ParametricAnalysisTool

• NOTE: when using cloud service please make sure to stop the cloud using the cloud button in PAT when your simulation session is done, and after you have downloaded all of the detailed results you want. You can then go the AWS Management Console to confirm the instances are terminated. If they are not terminated, you can manually terminate them from the console. We have a sticky post on our forum with best practices for cloud simulation in OpenStudio.

OpenStudio Platform, Including SWIG Bindings

• IdfObject::getQuantity and IdfObject::setQuantity functionality is almost, but not completely, comprehensive. The quantity getters and setters for fields whose units are "BasedOnField AX" are not expected to work at the IdfObject level, but are to be handled only for OS: prefixed objects by the specific interfaces of classes derived from ModelObject.
• The default naming scheme of WorkspaceObject (base class for ModelObject, etc.) sometimes results in undesired name clashes when transferring objects between models, including in the EnergyPlus translators. Therefore, some objects may be unexpectedly renamed or copied.
• OpenStudio::Model::ComponentVector objects may be inaccessible from the Ruby bindings. [issue #239]

Known Issues Specific to OS X

• To Install OpenStudio 1.0 and greater correctly on OS X you need to first uninstall earlier versions of OpenStudio. [issue #365]
• The SketchUp Plug-in toolbar tooltips do not work correctly on OS X if you have made your toolbars horizontal. The tooltips never show on OS X in the status bar. The button state may also be incorrect. This is a bug in SketchUp versus the plug-in. [issue #45]

Overview

OpenStudio 1.1.0 adds support for manual calibration of simulation results from monthly utility data. A new reporting measure type was introduced that has access to input data and simulation results that can be used to create custom reports and to perform automated quality control checks. Another major new feature is simulation using cloud computing resources through Amazon EC2. Users first set up an account with Amazon and link it to OpenStudio. The ParametricAnalysisTool (PAT) can then be used to run simulations locally or on Amazon EC2. This feature is still under active development to improve process connection and performance, and users are strongly urged to carefully review all disclaimer text and provided EC2 monitor web links in the cloud configuration dialogs. This version of OpenStudio also adds support for EnergyPlus 8.0 along with a number of new HVAC components.

New Features

OpenStudio Platform 1.1.0

• Added support for EnergyPlus 8.0.
• Added a new calibration feature that compares monthly utility data to simulation results. Users should use an actual meteorological year (AMY) weather file for best results.
• Added support for reporting measures that can process model inputs and simulation outputs as part of a workflow.
• Added back-end support for parallel simulation using Vagrant and Amazon EC2 instances. This feature is still under active development to improve performance and stability of distributed computing resources. Simulations in PAT may still be run locally as well.

OpenStudio SketchUp Plug-in 1.1.0

• Improved general performance, stability, and usability.
• Added shading controls for sub-surfaces.
• Added experimental user script to convert SketchUp groups to OpenStudio spaces.

OpenStudio Application 1.1.0

• Improved general performance, stability, and usability.
• Added Utility Bills Sub-tab in support of new calibration feature.
• New HVAC Components (Contributed by Oak Ridge National Laboratory)
  • GroundHeatExchangerVertical - Enables support for ground source heat pumps EvaporativeFluidCoolerSingleSpeed.
  • AirTerminalSingleDuctVAVNoReheat
  • AirTerminalSingleDuctConstantVolumeReheat
• New HVAC Components (Contributed by Group 14)
  • In-slab radiant heating/cooling, including water and electric resistance.
  • Chilled beams, both passive and active.
• Simplified measures library to show OpenStudio, EnergyPlus, and new Reporting measures side by side.
• Added calibration view to Results tab to view utility data side by side with simulation results.

OpenStudio ParametricAnalysisTool 1.1.0

• Simplified measures library to show OpenStudio, EnergyPlus, and new Reporting measures side by side.
• Added several additional Energy Conservation Measures to the Building Component Library, accessible through PAT and the OpenStudio application.
• Added Cloud Settings, Cloud Monitor, and a diagnostic dialog in support of simulations using the Amazon EC2 cloud computing service. Once the user creates an Amazon account and links to it from OpenStudio, OpenStudio can provision and distribute simulations across a user-selected number of EC2 instances.
• The Run tab was redesigned in support of simulations using cloud computing services. This includes a number of new interface elements and characteristics described below.
  • A cloud status button to display and alter the cloud state.
  • Design alternatives can now be selected and deselected for simulation. This can be accomplished by clicking on them individually, or by using the “Select All” and “Clear Selection” buttons. Previously there was no selection mechanism, and all design alternatives had to be run.
  • When a cloud instance is running, there is a new column to choose which design alternatives’ detailed simulation results should be downloaded upon completion. You can select these individually or select all, being mindful that simulation results can be quite large.
  • There is similar functionality to individually or globally clear simulation results.
• A button to download the highlighted design alternatives’ detailed simulation results was added to the Results tab.

Known Issues

The following are issues known at the time of publication of these release notes. Please contact [email protected] if you require further assistance.

Known Issues Common to All Platforms

OpenStudio SketchUp Plug-in

• If you use copy multiple on group-level OpenStudio objects, you will get one extra copy. The extra group is created by the first copy-and-paste operation and is not removed when the copy multiple occurs. To address this, after you perform a copy multiple procedure on groups or spaces, press delete. The objects you need to delete should already be selected. If you are copying loose surfaces such as windows, there are no problems, as SketchUp will merge equivalent surfaces. [issue #28]
• Using SketchUp's undo operation on OpenStudio model elements may produce unexpected results. [issues #54 and #150]
• SKP and OSM link is not maintained when files are relocated. You can manually re-establish that link. When opening a SketchUp file Launch SketchUp and then Open the SketchUp file. If that doesn't work you can also directly load the OSM file, bypassing the SKP file. [issue #409]
• It is possible for the OpenStudio Plug-in to conflict with other SketchUp plug-ins. If you suspect this is a problem, try testing with other plug-ins disabled, or contact [email protected] for assistance. [issue #26]
• Importing Constructions and Import Schedules from the OpenStudio SketchUp Plug-in are broken, but you can load an OSM file as library in the OpenStudio application and then selectively drag specific objects into your model. [issue #201]
• Using "Intersect" in the surface matching dialog can result in a crash or unexpected result. This is more common with models that were imported from other CAD formats at some point in the workflow. It is a good idea to save prior to using this to avoid any loss of data. This is related to an underlying SketchUp bug. [issue #168]
• "Project Loose Geometry" can crash SketchUp. It is a good idea to save prior to using this to avoid any loss of data. [issue #484]
• If your OpenStudio model crashes SketchUp or has unexpected behavior please forward it to [email protected] with a description of the problem. Please also include the directory that has the same name as the OSM file. You can attach it as a zip file.

OpenStudio Application

• When going to the Site / Utility Bills subtab after setting up the prerequisite objects you will see an object that can't be edited. That isn't a real object. To add your first object switch away from the "Electric Utility Bill" category at the left, and then click the green "+" to create a new object. [issue #577]
• The Site / Utility Rates subtab the workflow are marked as "coming soon," and will be completed in an upcoming release of OpenStudio.
• To enable set point schedule drop zones on the Thermal Zones tab, you need to first turn on the thermostat.
• Using the mouse scroll wheel while hovering over graphics in the Results Summary tab will unintentionally zoom them in and out. [issue #84]
• Similar thermostats assigned in the SketchUp Plug-in are shared across thermal zones in the OpenStudio application. Changing or turning off one will do the same to others. [issue #123]
• The view does not always refresh correctly when you delete a material from a construction. If you still see a material after clicking the "x", switch away from and back to the object to refresh the view. [issue #196]
• Not all of the schedules required to make a valid People object can be assigned in the application. [issue #107]

OpenStudio ParametricAnalysisTool

• If you plan to run an analysis using the cloud make sure to first run the baseline model locally. This will assure that at simulation results relative to the baseline show up on the results Tab. This is related to a bug in the order in which jobs are run on the cloud.
• As mentioned elsewhere, when using cloud service please make sure to stop the cloud using the cloud button in PAT when your simulation session is done, and after you have downloaded all of the detailed results you want. Then also go the AWS Management Console to confirm the instances are terminated. If they are not terminated, you can manually terminate them from the console.
• PAT won't prevent you from loading OSM files that are from a newer version of OpenStudio than you have installed, but the analysis won't run. [issue #330]
• Daylighting control object variables can't be requested in the output variables tab. [issue #355]
• The results tab may not be legible on a 1024x768 screen. [issue #359]
• Adding a design alternative using measure groups will remove any design alternatives made from external files. You can however add a design alternative made from external files without losing design alternatives made from measure groups. [issue #369]
• Always Run measures are applied to externally constructed design alternatives. This may result in unexpected results or errors. [issue #369]
• The run and cloud buttons may appear unresponsive after you click on them, particularly with very large projects. Please give them time, it may take a minute or two for the status to update.

OpenStudio ResultsViewer

• Alias changes do not update in table view until the data are read in again. [issue #25]
• Re-arranged column order doesn't stick next launch. [issue #30]

OpenStudio RunManager

• EnergyPlus ForwardTranslator errors do not appear in the RunManager GUI elements. [issue #181]

OpenStudio Platform, Including SWIG Bindings

• IdfObject::getQuantity and IdfObject::setQuantity functionality is almost, but not completely, comprehensive. The quantity getters and setters for fields whose units are "BasedOnField AX" are not expected to work at the IdfObject level, but are to be handled only for OS: prefixed objects by the specific interfaces of classes derived from ModelObject.
• The default naming scheme of WorkspaceObject (base class for ModelObject, etc.) sometimes results in undesired name clashes when transferring objects between models, including in the EnergyPlus translators. Therefore, some objects may be unexpectedly renamed or copied.
• OpenStudio::Model::ComponentVector objects may be inaccessible from the Ruby bindings. [issue #239]

Known Issues Specific to OS X

• To Install OpenStudio 1.1.0 correctly on OS X you need to first uninstall earlier versions of OpenStudio. [issue #510]
• The SketchUp Plug-in toolbar tooltips do not work correctly on OS X if you have made your toolbars horizontal. The tooltips never show on OS X in the status bar. The button state may also be incorrect. This is a bug in SketchUp versus the plug-in. [issue #45]

Overview

OpenStudio 1.0.0 adds life cycle cost objects to OpenStudio models and to energy conservation measures used in the Parametric Analysis Tool (PAT). In addition to being able to evaluate design alternatives based on energy use, users can now look at total life cycle costs, first year capital costs, annual utility savings, and simple payback. A new HVAC control view lets users set the operation time, night cycle operation, supply air temperature, economizer, and demand controlled ventilation for air loops. A major new category of HVAC equipment has been added with the introduction of an air to air heat recovery model, which can be used to model a variety of sensible and latent heat recovery devices.

New Features

OpenStudio Platform 1.0.0

• Added new model object LifeCycleCost for capturing capital and operating costs associated with building components and measures.
• Improved EnergyPlus IDF import and export. EnergyPlus export is now more repeatable and import is more stable.
• Improved consistency in the handling of multipliers throughout the OpenStudio model API.
• Suppressed erroneous log messages.
• All applications now catch thrown exceptions and report the error to the user before exiting or relaunching.
• BCL measures can now be updated to the latest version through the BCL dialog.
• Added and improved filesystem integration on Windows, Linux, and OS X, including imporoved installers.

OpenStudio SketchUp Plug-in 1.0.0

• Improved general performance and stability.
• Added OpenStudio SketchUp plug-in support for SketchUp 2013 (Pro and Make).
• Simplified plug-in user interface.
• gbXML import now handles files with malformed surfaces.
• Added "Export RPX File" for integration with the ASHRAE Radiant Performance Explorer human comfort tool. This can be found under "OpenStudio User Scripts / Reports".
• Improved default profiles on Ruleset Schedules.

OpenStudio Application 1.0.0

• Improved general performance, stability, and usability.
• Added a new "Controls" subtab for air loops in the "HVAC Systems" tab. This allows the user to set the HVAC operation schedules, night cycle, supply air temperature, economizer, and demand controlled ventilation.
• A major new category of HVAC equipment has been added with the introduction of an air to air heat recovery model, which can be used to model a variety of sensible and latent heat recovery devices.
• New HVAC Components
  • Water-to-air heat pumps
  • Water and electric baseboard heaters
  • Demand controlled ventilation
  • Night cycling
  • Air-to-air energy recovery
  • Constant volume pumps
  • Outdoor air based reset control strategy for air and water loops
  • Unit heaters
• Replaced "Scripts" tab with "Measures" Tab that is consistent with the Parametric Analysis Tool.
  • Measures added to a model in this tab will be brought into the Parametric Analysis Tool if the model is chosen as a baseline.

OpenStudio ParametricAnalysisTool 1.0.0

• Measures are now downloaded from the Building Component Library instead of being included in the installer. Users can download new measures as they are posted, and get updates to existing measures without having to install an update to OpenStudio.
  • If a new measure makes use of features added in a later version of OpenStudio then you will have to update OpenStudio if you want to use that particular measure.
• Updated measures now include inputs to support new life cycle analysis object in OpenStudio. Measures can add life cycle objects or manipulate objects that already exist. The following are some common inputs introduced, although specific inputs will vary from measure to measure.
  • Material and Installation Cost
  • Years Until Costs Start (number of years left until due to be replaced)
  • Demolition Cost Occur During Initial Construction (true/false)
  • Expected Life
  • O&M Costs
  • O&M Frequency
• Added "Always Run Measures" that operate on the baseline model as well as each design alternative.
  • These measures can run at various stages defined by where the user places them relative to the measure groups in the project.
  • Some measures added to the Building Component Library that were designed to be used as "Always Run Measures" are under "Economics -> Life Cycle Cost Analysis". Many of these add life cycle costs to objects in the model.
• Added new columns to the "Reports" tab to show First Year Capital Cost, Annual Utility Cost, Simple Payback, and Total Life Cycle Cost.
