Every time I open the hot water loop in my model it crashes. Any ideas as to why this would happen? 
I figured out the issue. I was deleting a cooling coil from the text editor without deleting the associated inlet and outlet nodes. Once I followed the OS IDs to the inlet and outlet nodes and deleted them OpenStudio no longer crashed when opening the HW loop.
It may seem strange that a cooling coil affected the HW loop, but this coil was actually placed on the HW loop originally with a measure and subsequently deleted and replace with a DX cooling coil.
Always use the app or the API to delete objects. If you do it in a text editor, residual objects will get reference/link errors and crash the app, particularly for HVAC objects.

Can you provide more details about the history of the model and what version of OpenStudio you are using.
I am using version 2.1. What information about the history of the model will be helpful?
