Hey Unmet!

Is it at all possible to deploy the OpenStudio command line interface to a remote server? I am trying to develop lightweight calculation tools without the user having to download the actual software. Ideally, I would like to use a web interface to feed inputs to a .osw file which then would be feed to the CLI to produce reports that would be displayed to the user in a web browser.

Any help or advice would be greatly appreciated!

Hello Unment!

I am currently writing a measure to replace the existing hot water boiler curves with custom bi cubic and bi quadratic curve coefficients. I have run into an issue with the curve replacement. I run through the current curves for the boilers and delete them, and then try to plunk in the new curve objects.

I've been met with this error within the hot water boiler object field:

"Undefined method setNormalizedBoilerEfficiencyCurveName for #.

I convert the hot water boiler to the correct class but I am not sure why I am unable to access this field? I am able to modify the other fields of the Boiler object besides the ones with hashed values. Bellow is code for reference.

# define the new Biquadratic curve object
condensingBoilerEfficiency = OpenStudio::Model::CurveBiquadratic.new(model)
condensingBoilerEfficiency.setName("CondensingBoilerEff")
condensingBoilerEfficiency.setCoefficient1Constant(1.124970374)
condensingBoilerEfficiency.setCoefficient2x(0.014963852)
condensingBoilerEfficiency.setCoefficient3xPOW2(-0.02599835)
condensingBoilerEfficiency.setCoefficient4y(0)
condensingBoilerEfficiency.setCoefficient5yPOW2(-0.00000140464)
condensingBoilerEfficiency.setCoefficient6xTIMESY(-0.00153624)
condensingBoilerEfficiency.setMinimumValueofx(0.1)
condensingBoilerEfficiency.setMaximumValueofx(1.0)
condensingBoilerEfficiency.setMinimumValueofy(30)
condensingBoilerEfficiency.setMaximumValueofy(85)



    model.getCurves.each do |curve|
      if curve.name.to_s == "Boiler with No Minimum Turndown"
        handle = curve.handle
        model.removeObject(curve.handle)

      end

    end
    water_unit = boiler_water.to_BoilerHotWater.get
    water_unit.setName("CondensingBoilerEff")
    water_unit.setNormalizedBoilerEfficiencyCurveName("CondensingBoilerEff")
    water_unit.setNominalThermalEfficiency(1)

  end

here is a reference to the class that I am using. Any help would be greatly appreciated!

Thank you so much!

Hello Unmet!

I am just curious if there is an alternate way of opening a .sql file other than writing an Open Studio reporting measure or using Dview. I would like to manipulate the .sql data via Pandas in python but upon some research, I've found that that would require a remote database connection?

In other words, Is there a way to open an existing .sql file in python, make queries to the E+ data tables, and then use that data?

Any guidance would be appreciated!

Hello Unmet!

I am currently writing a python GUI to overlay the OS CLI and need some advice on how to evoke a system call with the parameters and workflow.osw file. This issue that I am finding is that when I use a Python system call, the model does not successfully run. When I use the same call in a ruby file, the model runs perfectly.

These are the commands from both of my scripts:

 Python: subprocess.run("openstudio run -w MedOfficeSeed\modified.osw")
 Ruby:  system 'openstudio run -w MedOfficeSeed\workflow.osw'

I believe the problem could be rooted in the ruby dependency that Open Studio has. The CLI also works normally when I use the cmd prompt outside of my GUI application.

I know this question may be out of context from the bulk of the queries on here but was hoping someone could lend some advice. I would really like to avoid writing the GUI in Ruby!

Thank you, Particle Swarm

I am currently trying to set up the command line interface for for measure testing. I modified the PATH variable to point to the OpenStudio version of ruby to use.

I also tried putting a .rb file in the site_ruby file Path and overall I am getting an error of "Cannot load such file" -- openstudio.so (LoadError).

I am using OpenStudio version 2.5.1, and have the latest install of ruby 2.4

ruby files are executable from the directory with a hello-world that I tested, so I am not sure why it cannot load the openstudio.so file or that its not finding it. They are in the same directory.

UPDATE: downgraded my Ruby to 2.2.4 to see if that would fix the issue, no luck. Still getting an error "LoadError: cannot load such file -- openstudio.so"

Thank you for the quick response! When I am back at work I will post my environment variable configuration as well as m

Hello Unmet Hours!

I am currently writing a measure to modify schedules in Open Studio and was wondering if it is possible to get time data when a certain set point or threshold is reached. for example, I would like to grab the time of day based on when the building was occupied; specifically the start time of the day.

I am still new to writing measures so any info would be extremely helpful.

Thank you
