I am trying to modify the default FuelFactors in openstudio. I have written a tool using openstudio sdk. It seems to be working fine in the .osm (it introduces OS:FuelFactors object in the .osm) but when I run the simulation the equivalent instance in the energyPlus file (FuelFactors,) is missing.

Any clues? Thanks for your attention.

I an having problems with a measure that used to work fine in openstudio app 2.9 but now in some cases is failing in 3.4.

the problem appears when I call the uFactor method of a subsurface object from a measure. For example, when i call

window.uFactor

I get the the following error:

Result: Fail
Error: Error creating prepared statement: SELECT Value from TabularDataWithStrings
WHERE ReportName = 'EnvelopeSummary'
AND ReportForString = 'Entire Facility'
AND TableName = 'Exterior Fenestration
AND ColumnName = 'Glass U-Factor'
AND Units='W/m2-K'
AND RowId = ?; with error code 1, extended code 1, errmsg: near "Glass": syntax error
C:/Users/EFINOV~1/AppData/Local/Temp/osmodel-1662883600-0/resources/measures/verificacion_ctehe1_2019/measure.rb:1370:in `uFactor'

There are a few funny things: - It never fails in a ruby script inside sketchup - In an openstudio measure fails in some cases. I guess it depends on the glass construction name or the construction set name, but after several tries with different names I couldn't reach any conclution.

Any ideas?

Thanks

I have found a work arround. I have noticed that at the begginig of the run method there is no problem getting the uFact

Just to point it out, in the error message, in the prepared statement there is a missing ' after Exterior Fenestration.

I have just notice that parameter Timestep in the OpenStudio settings is not being used in the simulation. For example, if I choose 6, this step is ok in the .osm file:

OS:Timestep,
  {210f49e8-ab04-4b81-b6fd-0fac6eeadcbc}, !- Handle
  6;                                      !- Number of Timesteps per Hour

But in the in.idf file it will always remain 4:

Timestep,
  4;                                      !- Number of Timesteps per Hour

Am I missing something?

I need to modify this value because I am using custom weather data with subhourly values. I guess the only workaround is to write a energyplus measure to modify this value.

Thank you very much for your comments. You were right. I was also using a tariff measure that was changing the timestep.

Openstudio measure needs to access system variables I am writing a measure that requires executing an external program.

I am writing an Openstudio measure that needs to access the values defined in a schedule defined by "ScheduleRuleset" with different rules. I have written something like this:

sch = model.getScheduleRulsetByName("Schedule name").get
start_date = OpenStudio::Date.new(OpenStudio::MonthOfYear.new("Jan"), 1)
end_date = OpenStudio::Date.new(OpenStudio::MonthOfYear.new("Dec"), 31)

I have the following problems:

• sch.getDaySchedules(start_date, end_date) always returns the default day (although there are other rules defined for these days)
• sch.getActiveRuleIndices(start_date, end_date) always returns an array filled with -1 (no valid rule for this day).

What am I doing wrong? Is there another way to get the schedule values?
