Overview

OpenStudio SDK:

OpenStudio HVAC capability was extended with the following additions:

• New Model API AirLoopHVACUnitarySystem::setControlType
• Allow AirLoopHVACUnitarySystem object as Zone HVAC Equipment
• Added support for more E+ fields in pump objects
• Added new Model object, AirTerminalDualDuctVAVOutdoorAir
• Added support for more E+ fields in cooling tower objects
• Added support for more E+ fields in the AvailabilityManagerNightCycle object.
• Allow ZoneHVACTerminalUnitVariableRefrigerantFlow to be configured without a heating coil

Many new external interface objects have been wrapped and are available in the API:

• OS:ExternalInterface
• OS:ExternalInterface:Schedule
• OS:ExternalInterface:Variable
• OS:ExternalInterface:Actuator
• OS:ExternalInterface:FunctionalMockupUnitImport
• OS:ExternalInterface:FunctionalMockupUnitImport:From:Variable
• OS:ExternalInterface:FunctionalMockupUnitImport:To:Schedule
• OS:ExternalInterface:FunctionalMockupUnitImport:To:Actuator
• OS:ExternalInterface:FunctionalMockupUnitImport:To:Variable
• OS:ExternalInterface:FunctionalMockupUnitExport:From:Variable
• OS:ExternalInterface:FunctionalMockupUnitExport:To:Schedule
• OS:ExternalInterface:FunctionalMockupUnitExport:To:Actuator
• OS:ExternalInterface:FunctionalMockupUnitExport:To:Variable

The Energy Management System (EMS) Actuator actuatedComponent method was changed to return an Optional to handle cases where the modelObject is deleted during Forward Translation without the knowledge of the actuator.

EMS Actuators can now be constructed with SpaceLoads. To use, pass a SpaceLoad object to the constructor and the Actuator will be attached to the “ThermalZone SpaceLoad” object as required by the Actuator naming convention.

The EMS Sensor constructor was changed to use the OutputVariable keyValue if it is not defaulted (since * is not a valid value for EMS)

OS:Output:Variable, OS:EnergyManagementSystem:OutputVariable, OS:ExternalInterface:Schedule, OS:ExternalInterface:Variable, OS:ExternalInterface:Actuator have received the new IDD field “Export To BCVTB” which defaults to “True”. If set to true, it will add the variable or external interface object to the variable.cfg file that is now auto-generated on E+ translation. Note: the order of the variables in the file is not guaranteed to remain the same between different translations, however it can be easily hand-edited.

The OpenStudio SDK now includes the EMPD (Effective Moisture Penetration Depth) model, a simplified approach to simulate surface moisture adsorption and desorption.

OpenStudio Server

Several new algorithms have been added to the OpenStudio Server and are available through PAT:

• GA (https://cran.r-project.org/web/packages/GA/GA.pdf) is a single objective Genetic Algorithm with hybrid gradient search that will added in a future release.
• GAIsl (https://cran.r-project.org/web/packages/GA/GA.pdf) is an Islands Genetic Algorithm where parallel independent GAs are executed in each island and only occasionally sparse exchanges of individuals are performed among the islands.
• fast99 (https://cran.r-project.org/web/packages/sensitivity/sensitivity.pdf) is the Extended Fourier Amplitude Sensitivity Test. fast99 implements the so-called "extended-FAST" method (Saltelli et al. 1999). This method allows the estimation of first order and total Sobol’ indices for all the factors.

Existing OpenStudio Server algorithms received the following improvements:

• Morris R2 parameter is available for using the Campolongo space filling improvement.
• Sobol now has the following methods available for computing Sobol indices:
  • Sobol
  • Sobol2002
  • Sobol2007
  • Jansen
  • Mara
  • Martinez
• 'random_seed' is now an algorithm level parameter and can be set for reproducibility across analyses. The default value is nil which makes repeated runs non-deterministic.
• R is now using version 3.4.2.
• Rserve is now using version 1.8-4.

Known Issues

DView is not currently available in Ubuntu packages. We hope to address this in the near future.

Overview

The biggest new feature in OpenStudio 2.3.0 is the integration of the OpenStudio Geometry Editor in the OpenStudio Application. The OpenStudio Geometry Editor is a new, open source software module that developers can leverage to produce building energy modeling UIs that include geometry creation. The OpenStudio Geometry Editor is meant to cover simple building geometry use cases only. More complex building geometry is best developed in a full featured CAD tool and exported to gbXML for building energy modeling. The OpenStudio Geometry Editor is implemented in JavaScript with minimal dependencies, allowing it to be integrated into a wide range of applications. The OpenStudio Geometry Editor reads and writes a custom floorplan.json JSON file format. New methods have been added to the OpenStudio SDK, which can translate this file format to OSM. Additionally, new methods have been added to the SDK, which allows two OpenStudio Models to be merged. These new methods are demonstrated by integrating the Geometry Editor directly within the OpenStudio Application. The OpenStudio Geometry Editor and integration within the OpenStudio Application are experimental, and are not recommended for production workflows. However, we invite users to try these software components out and provide feedback to help us make them better for use by third party developers. Instructions for use are at: http://nrel.github.io/OpenStudio-user-documentation/reference/geometry_editor/

EnergyPlus

Openstudio now incorporates EnergyPlus Release 8.8, which provides additional speed improvements, as well as bug fixes.

OpenStudio

Through workspace code optimization, large HVAC model creation time has been reduced by roughly 75%. An example test model which originally took 416 seconds to create, took only 101 seconds after this code improvement.

DView

For many years, OpenStudio has included ResultsViewer to visualize timeseries data. In this release, ResultsViewer is now replaced by a visualization tool called DView which was originally developed for viewing residential building and solar energy simulation data. DView brings additional capabilities that ResultsViewer does not have, including IP unit conversion, CSV data import/export, image export, EPW weather file visualization, two synchronized views, stacked timeseries, average profiles, overview statistics, histograms, cumulative density plots, duration curves, and scatter plots.

Known Issues

DView is not currently available in Ubuntu packages. We hope to address this in the near future.

PAT's algorithmic method 'RGenoud' is unstable. A software patch will be provided once a fix is in place. Please use 'PSO' until it's fixed.

Overview

DView: the future ResultsViewer replacement
For many years, OpenStudio has included ResultsViewer to visualize timeseries data. The plan for the next OpenStudio release (2.3.0) is to replace ResultsViewer with a visualization tool called DView, which was originally developed for viewing Residential Building and Solar data. DView brings additional capabilities that ResultsViewer does not have, including IP unit conversion, CSV data export, image export, EPW weather file visualization, two synchronized views, stacked timeseries, average profiles, overview statistics, histograms, cumulative density plots, duration curves, and scatter plots.

DView can load EnergyPlus .sql files just like ResultsViewer. Please download DView via the links below, try it out, and send any feedback you may have.

The Hourly, Daily, and Monthly graphs allow you to turn variables on or off with a single click, and to zoom and pan very easily. DView has the ability to display simultaneous line and stacked areas as demonstrated in the Hourly graph below.

Hourly graph

Daily and Monthly timeseries graphs are automatically created by averaging or summing the hourly data:

Hourly graph

Daily graph

Monthly graph

If the underlying data is sub-hourly, an additional Timeseries graph displays the raw data and the Hourly graph becomes the result of averaging or summing. If the underlying data is multi-hourly (for example, a 3-hour timestep), a Timeseries graph displays the raw data, there is no Hourly graph, and the Monthly graph is the result of averaging or summing the timeseries data

The Heat Map graph displays a whole year of data at once, with the day of the year on the x-axis and time of day on the y-axis, so that each time step corresponds to a small rectangle. That rectangle gets assigned a color based on the value in that time step. Using this format, it is possible to identify both diurnal and seasonal patterns. The example below shows the direct normal solar radiation in Boulder, Colorado from the TMY2 data set. The image shows that the days are longer in the summer than in the winter, the most intense direct radiation values tend to occur in the spring and fall, and summer afternoons tend to be cloudy:

Heat map graph

The Profile graph illustrates average daily profiles for each month of the year (with the ability to also show an annual average daily profile). The graph below demonstrates daily profiles for electric cooling and gas heating in a building:

Profile graph

The Statistics table shows annual or monthly statistical values (e.g., mean, minimum, maximum, sum) for each variable in tabular format:

Statistics table

The PDF/CDF graph shows the Probability Distribution Function (PDF) and Cumulative Distribution Function (CDF) for the dataset. These functions are useful to illustrate the distribution and spread of values for a given variable:

PDF/CDF graph

The Duration curve orders the data from highest value to lowest value. By doing so, one can quickly identify, for example, the number of hours for which the variable is above or below a certain threshold:

Duration curve graph

The Scatter plot allows graphing one or more y-axis variable against an x-axis variable. For example, the below graph shows a scatter plot for space heating and space cooling in a building as a function of outdoor drybulb temperature. It can also be useful to compare measured data against simulated data (for which the "line of perfect agreement" can also be displayed).

Scatter plot

OpenStudio Application
OpenStudio Application now provides a newly implemented 3D geometry preview tab.

OpenStudio Model
OpenStudio Model received the following updates:

• Exposed SetpointManager:FollowGroundTemperature - Reference Ground Temperature Object Type to the OpenStudio API
• Added UnitarySystemPerformance:Multispeed object
• Allowed Availability Manager to be attributed to Plant Loop
• Permitted glycols to be used in Plant Loop
• Added GroundHeatExchanger:Vertical gFunctions

Additionally, the following objects have been wrapped:

• GeneratorFuelCell
• GeneratorFuelCellPowerModule
• GeneratorFuelCellPowerModule
• GeneratorFuelCellAirSupply
• GeneratorFuelCellWaterSupply
• GeneratorFuelCellAuxiliaryHeater
• GeneratorFuelCellExhaustGasToWaterHeatExchanger
• GeneratorFuelCellElectricalStorage
• GeneratorFuelCellInverter
• GeneratorFuelCellStackCooler
• GeneratorFuelSupply

The GeneratorFuelCellExhaustGasToWaterHeatExchanger object works in the OpenStudio Application and when added to a plant loop, adds all necessary GeneratorFuelCell and related components to the model and is user-configurable in the OpenStudio Application.

OpenStudio Standards Gem
OpenStudio Standards Gem was updated 0.1.15. This added additional HVAC system types.

OpenStudio Workflow Gems (WFG)
OpenStudio Workflow Gems have been updated to 1.3.0 which offers the following refinements:

• ScriptError subclasses, including LoadError and SyntaxError, as well as NoMemoryError are now handled by the WFG and persisted to the log
• New method runner.haltWorkflow(completedStatus) stops the execution of additional measures and the simulation, and sets the datapoint's completion status appropriately

OpenStudio Server
OpenStudio Server’s robustness has been improved with the following updates:

• Fixed an issue where output variables would overwrite each other if the same measure was run multiple times
• Ensured that all results are available in the csv results list, not just those which were completed successfully
• Changed algorithm retry procedures to ensure no infinite looping of datapoints
• Support datapoints being halted using the runner.haltWorkflow method
• Minor extensibility improvements
• Ensured all deployment environments support configuration of the R queue size
• Variable distribution plots are working again for LHS analyses

Overview

The OpenStudio 2.x line is an aggressive overhaul of OpenStudio to make the SDK smaller and more accessible for third party software developers. The new package includes two major new components: a command line interface (CLI) and a new version of the Parametric Analysis Tool (PAT). A new component based installer gives users the choice to install only the components that they need. OpenStudio 2.1.0 is the first major release of the OpenStudio 2.x line.

The OpenStudio command line interface (CLI) allows software developers to execute a series of OpenStudio Measures and other simulation steps as described in an OpenStudio Workflow (OSW) file. The OSW defines a set of paths to search for OpenStudio Measures, initial seed model, weather file, and other supporting files. When an OSW is run through the CLI, the initial seed model is loaded and OpenStudio Model Measures are applied to the seed model. After these measures, the OpenStudio Model is translated to EnergyPlus IDF format. Once in EnergyPlus IDF format, OpenStudio EnergyPlus Measures are applied. After these measures, the EnergyPlus simulation is executed. Once the EnergyPlus simulation is complete, OpenStudio Reporting Measures are applied which generate reports. Once the workflow is completed (successfully or unsuccessfully), an output OSW file is written which contains output related to running the workflow. The OpenStudio CLI contains a Ruby interpreter, Ruby standard library, OpenStudio Ruby bindings, and a core set of gems (including the OpenStudio Standards Gem). It does not have any shared library dependencies outside of system runtime libraries. EnergyPlus and Radiance are not embedded within the CLI, they are included as part of the OpenStudio installation. There is an example OSW included in this package in the compact_osw directory under the Examples directory. This example contains everything to run a simple OpenStudio workflow from loading a seed model, applying measures, running EnergyPlus, and running reporting measures. To run this example:

cd path/to/Examples/compact_osw
./path/to/openstudio.exe run -w compact.osw

More information about the OpenStudio CLI is available at: http://nrel.github.io/OpenStudio-user-documentation/reference/command_line_interface/

A new version of the OpenStudio Parametric Analysis Tool (PAT) is part of OpenStudio 2.1.0 packages. This new version of PAT has been rewritten from the ground up as an example of JavaScript application development with OpenStudio. It has been packaged as an Electron desktop application and leverages OpenStudio Server for improved robustness, scalability, and capability. This new version of PAT provides similar functionality (and we hope improved usability) as compared to PAT 1.14.0. However, the new version of PAT is not backwards compatible with PAT 1.14.0 projects. Additionally, this new version of PAT supports “algorithmic” workflows – methods for automatically generating large sets of analysis data points. Choose from Design Of Experiments, Latin Hypercube Sampling, multiple optimization methods, and more to identify the most sensitive parameters in a model, calibrate a model against real consumption data, or optimize a model to balance multiple design objectives. Algorithmic analyses tend to be computationally intensive, so the new PAT supports simulation on Amazon Web Service or other resources provisioned with OpenStudio Server.

The Radiance functionality (Radiance Daylighting Measure) has been updated to work with OpenStudio 2.x, including the OS Application, PAT, and Server. The measure has been relocated to the Building Component Library, but its operation remains the same. The measure is also backward compatible to OpenStudio v1.14.

The Ruby and C# binding footprints have been greatly reduced in the OpenStudio 2.1.0 package. Previously, deploying the Ruby and C# bindings required deployment of many shared library and file dependencies. In OpenStudio 2.1.0, the Ruby bindings are contained in a single openstudio.so (.bundle on Mac) file and the C# bindings in an OpenStudio.dll and two supporting dll files. These are the only files required to distribute the OpenStudio 2.1.0 bindings with a third party application. Note that the openstudio.so Ruby file does not contain any gems or the Ruby standard library; these must be configured using typical Gemfile configuration for your Ruby project. Similarly, the C# bindings do not include a Ruby interpreter or OpenStudio Ruby bindings needed to apply OpenStudio Measures. If a C# project desires to run measures or simulations, it can write an OSW file and make a system call to the CLI.

OpenStudio 2.1.0 is mostly backwards compatible with OpenStudio 1.1.4. One primary difference is that PAT is not backwards compatible with PAT 1.1.4 projects. Also, upgrading a 1.1.4 version OSM to 2.1.0 will not preserve the associated run.db, any measures associated with the OSM will have to be re-added in 2.1.0. The API for OpenStudio Model and other core namespaces was mostly preserved during the OpenStudio 2.1.0 conversion. However, the RunManager, Analysis, Project, and AnalysisDriver namespaces were completely removed. The CLI and OSW format replace the functionality of RunManager. The OpenStudio Analysis (OSA) format replaces the functionality of Analysis, Project, and AnalysisDriver. The Ruleset namespace has been renamed to Measure to better reflect its functionality.

OpenStudio 2.1.0 has been updated to EnergyPlus 8.7, Ruby 2.2.4, and is compatible with SketchUp 2017. ResultsViewer is included in the 2.1.0 release.

Known Issues

This is a list of known issues, if you find an issue not on this list please let us know so we can fix it.

Installer

• Spaces in the install path will cause PAT to fail.
• Firewall rules are not configured at install time, user is prompted to allow http communication between OpenStudioApp and the CLI as well as between PAT and the CLI.

Measures

• Measures written for OpenStudio 1.14.0 and earlier may not work with OpenStudio 2.0.0, measure authors are encouraged to test their measures and update them to ensure compatibility.
• Reporting measures do not have access to offline JavaScript libraries included with the OpenStudio installation. Measure writers can include offline JavaScript libraries in the resources directory of their measure.

OpenStudioApp

• The app may appear to freeze on return from BCL measure dialog on Mac, a workaround is to select File -> Quit and when prompted to save the Model, select cancel to abort the quit operation or press the escape key.
• Using the file menu very quickly after launching OpenStudio may cause a crash if the OpenStudio Results measure has not been downloaded on Mac. Wait until the vertical tabs are re-enabled before using the file menus.

PAT

• “Create One Design Alternative with Each Measure Option” duplicates options that already exist
• Cannot enter user defined string for Measure Choice arguments
• Display name is not shown when browsing measures
• Measures associated with seed model are not imported
