Dear fellas! I want to import my open studio model to idf file. I want to define some parameters in energy plus, but the idf file always pre-defined the building type as an office. I already change the building type as a building as I want, which is large hotel. But after I change it in the sketch-up on-demand templates generator it always back to Office. It makes me need to delete some definition like scheduling and materials. How to change the default building type?. Thank you!

You can convert a .osm file to an .idf by opening it in the OpenStudio app, File -> Export -> IDF.

I'm unclear why you need Sketchup to convert your OpenStudio model to an .idf. Perhaps I am missing part of your question.

Thank you for your response. I need Sketchup because my model build in SketchUp (with openstudio extension) then I convert the osm file to idf file in SketchUp. During modeling the building, the building type always defined as an office, when I change it, it will be back to office.

An OpenStudio model built in SketchUp is an OpenStudio model that you can and should open and manipulate with the OpenStudio app. You can re-open the model later in SketchUp if you need to make geometry changes. In fact, you need to go into the app or use an other tool outside of Sketchup to define HVAC components. SketchUp is intended for geometry creation, and then you finish the model in OpenStudio. You export as an .idf in the OpenStudio app.

Also, the on-demand template generator is just an OpenStudio measure. The input arguments have defaults, which is office as you noted above. Once you've applied this to your building, the building will have the defaults according to the arguments you specified if you selected the 'Set Building Defaults Using New Objects' argument. If you inspect your model and look at the Model::Building object, you should see the defaults you specified. You should really be doing this in the OpenStudio App.

Well, as I understand, so the building will always have default based on template generator. But in my openstudio, even I've changed the template generator to large hotel or other building types except office, it will be back to office, then if I lunch the open studio, it defines as office, such as the schedule, construction, etc. I think my problem is the availability of my default library because there just two files are hvac_library and office_default.

What is the default building type in your OpenStudio::Model::Building object?
