Sorry that I’m so late here in seeing several people struggling with the custom Python component. In light of all of this, I decided to add an official component for “HB Filter Room Results”
You can get the component on your end right now by running the LB Versioner and it will be included in the next Pollination installers. Also, as you can see in the screenshot above, the HB Rooms by Attribute component now has an new input for value_, which can be used to filter the input rooms/model for a particular value of an attribute. This way, it’s straightforward to get things like “all of the data collections for the cooling in the classrooms.”
Hopefully, this makes it easier for everyone. I guess I had previously thought that people were able to access this room result matching functionality tangentially through components like HB Color Rooms or HB Normalize by Floor Area but neither of these really did exactly what was needed for some workflows. Thanks again to everyone who brought this up.
