  2. Improve Output Variables Reporting

    Problem: The current Output Variables tab does not include all OVs available and the Add Output Variables measure is cumbersome to use.

    Rationale: Hourly output can be extremely useful for trouble shooting.

    Solution: The existing Output Variable tab could be improved to show all OVs from the last sim's RDD file or none if the model has not been run yet. Additional features that would be useful are the ability to select groups of OVs and an option for specifying an OV's Key Value.

    One solution could be to group OVs into expandable category bars similar to the Library sidebars…

  3. Allow rearranging HVAC equipment in Thermal Zones tab

    Problem: Currently there's not a quick way to rearrange ZoneHVAC equipment in the Thermal Zones tab without a measure. In order to switch the order of equipment the user must delete ZoneHVAC objects losing any user-specified inputs.

    Rationale: Heating and cooling priority is set by the order of the ZoneHVAC objects assigned to a zone in the GUI. Not all users are aware of this and it can significantly affect model results.

    Solution: Explicitly show the user heating and cooling priority. Add a Grid View feature to increase or decrease selected equipment priority.

    Context: ZoneHVAC:EquipmentList

  4. Curve editing in OpenStudio

    Problem: There's no easy or user friendly way to edit or add new curves

    Rationale: It would be nice to be able to edit the curve coefficients/add new curves for say a chiller directly in OpenStudio. I've found that creating them manually in notepad++ is unstable at best and not user friendly.

    Solution: Implement a new pane where one can add a curve or edit one when you click on a given curve attached to a specific HAVC equipment

  5. Add multi-choice arguments for measures

    Problem: Measure interface currently does not support multiple choice arguments.

    Rationale: It is also something that would be nice when you want to run a measure on 5 out of 20 zones in a model. You cloud have a single measure, vs. 5 instances of the same measure.

    Solution: Add multi-choice arguments for measures

  7. Organize HVAC library by category

    Since 1.9.0, the quantity of available library objects when viewing the "HVAC System" makes it really hard to find an object.

    It'd be great to categorize the objects, for example following the EnergyPlus "Groups" (in the I/O documentation, or when using IDF editors)

  8. Add capability to perform CFD analysis

    Many building energy modeling tools (e.g., IES-VE, DesignBuilder) have integrated CFD analysis.

    Perhaps OpenStudio could integrate OpenFOAM analysis for spaces with visualization through ParaView.

  10. Grid view column headers should stay fixed when scrolling

    Problem: When scrolling grid view if headers do not stay fixed it is very difficult to tell what each column is.

    Solution: Implement a view similar to Excel's "freeze panes" in gridview

  12. Add user controls to default results reporting

    Problem: no user control exists for new 'OpenStudio Results' report. The measure the report is based on included user arguments to include/exclude various reporting sections, which was useful for some models, and especially to override the inclusion of 'Zone Air Temperature' and 'Zone Air Relative Humidity' output variables, which the report adds automatically and are not always desired in the output.

    Solution: expose user arguments to include/exclude report sections from the default OpenStudio Results report somewhere in the GUI, most likely the 'Output Variables' or 'Simulation Settings' tabs.

  13. Support for baseline compliance models

    Problem: Performance energy models for code compliance or rating programs (T24 CBECC-COM, 90.1, LEED), require specific model inputs for a baseline and proposed model. Other simulation software on the market is able to build these baseline models, and generate standard compliance reports. Often, these simulation softwares are selected for projects, not because they are nicer to work with or have greater modeling capability, but simply because the can generate a baseline model and report with all the embedded rules. OpenStudio/EnergyPlus would get much greater adoption if it could provide this functionality.

    Solution: Add a component to the OS App to…

  14. Improve drag and drop response time in OpenStudio

    When dragging and dropping model or library elements into an OpenStudio section (e.g. dropping a thermal zone into an air loop), the app takes several seconds to register before it allows further input. It makes the App annoying to use at times. Faster response (<0.25s) would improve usability.

  15. Allow editing multiple elements of same type withinin SketchUp plugin

    Currently if you select two of any model element (two spaces, two subsurfaces, etc) the Inspector tool reverts to the OS:Building view and you are not able to edit properties specific to the element type in your selection.

    I propose the plugin include a check to see whether all elements in the selection are of the same type, and if they are then allow the Inspector tool to be used to edit the properties of that element type. It would be very valuable, for instance, to be able to select a group of spaces or zone and modify a property…

  17. Improve grid views performance for big models

    Working with real models with 400+ spaces and 4000+ surfaces would be really helpful from grid views. Surprisingly, they are very slow with such size. More filters could be useful as well

  18. Built-In Air-Cooled Chiller Curve Incorrect

    At some point in recent versions, an air-cooled chiller object was built into the HVAC library. The issue is, one of the curves that's attached to that chiller causes the energy usage of the chiller to increase as the load on the chiller decreases. Seems like someone must have just grabbed the wrong curve when making that change.

    I don't think it's important specifically what curve is used, but the curve should at least be representative of the general behavior of a chiller. I'm attaching a chart comparing the value of this curve to a couple of other standard curves.…

  19. allow user to specify VRF condenser type in GUI

    Many inputs related to water-cooled and evaporatively cooled condensers are editable for VRF systems but only air-cooled condensers for VRF systems are supported in the app.

    It would also be helpful if users could drag a VRF system to the load side of a condenser loop.

  20. Add ability for OS app to look for updated BCL components and measures.

    Problem: Consumers of BCL components are not updated when components are updated.

    Rationale: Currently the user has to know something has been updated on BCL, to decide to update it, or stumble across it when searching for something else. A number of times I had updated measures but users didn't know there was a newer one with new features and or bug fixes. It would be great for a way in the GUI to update all BCL content for the latest version that works on my OS version.

    Solution: Prototype a measure that performs update management of other measures; the…
