For some reason the building component library has stopped downloading files from within the OpenStudio Application. When I click "Components and Measures" and then "Find Components" and access the BCL this way, whenever I select a material and click download, the loading bar just whirrs away forever. I can however download the zip file from the BCL website, but I don't know where to put this file so that I can access it in the OpenStudio Application. I tried pasting it into the ~/BCL folder but that did not seem to work.

Does anyone have any pointers? I'm a bit stuck without it!

@jaklloyd, thanks for pointing this out. I was able to duplicate this behavior and have filed an issue. A work around since you can download the component using a web browser would be to go to follow these steps.

  1. Download component from web browser
  2. Unzip contents
  3. Go to file menu in the OpenStudio application and choose "Load Library"
  4. Browse to and select the OSM file from the unzipped component.
  5. You should now see the material in the library, but it won't have a blue "BCL" tag on it like it would if downloaded directly through the Application.

Thanks! This works very well as a work around. As another bug, the in-built BCL browser in OpenStudio Application seems to crash if you include a space character in the search. OpenStudio immediately closes when I do this. Perhaps it is worth filing an issue for this too?

What if the component is only comprised of an xml file? For example, "Generic T12 40W Linear Fluorescent" does not have an osm file that can be loaded to the library. How does one access this with the OpenStudio app?

This solution does not work for me. I already downloaded the same material within OpenStudio and I tried to use the load library function to no avail. Does anyone have any further tips/methods to do this?

Hi, you can paste it in the measures folder in the below path - C:\Users\yourusername\OpenStudio\Measures. i had downloaded measures from the BCL and extracted it in the measures folder.

This is true for Measures, however I am concerned with Materials. The C:\Users\yourusername\BCL folder is where the other building components are located however they all seem to have subfolder names such as "c618f299-a245-49ce-a119-82eb54007ede". When I paste a folder in there called "Brick - Fired Clay - 4 in. - 120 lb" this Material does not appear in my library when I am in the OpenStudio Application. Therefore I still don't know how to access these downloaded Materials when in the OpenStudio Application. Does anyone know where I can paste these folders? Or what I can rename them to?
