Energy Analysis Failed

[Anonymous]

Hi all,

I am trying to conduct an energy analysis (the built-in one in Revit, not Insight 360) but I keep getting an error that says the energy analysis has failed. I've attached a screenshot of the error message from GBS. When I hovered over the red "X" icon, I simply get an error that said "Aborted run". This is weird because I never "aborted" it. It failed by itself. When I searched on this forum for this problem, other forum users have posted different messages than "aborted run".

I cannot seem to pin point the problem. According to forum posts, the 2 main causes are duplicate vertices and elements that are too thin/thick. I've corrected these issues in the model (even deleting complex families), but the problem persists.

try the following:

1. Verify Energy Settings for project are set up properly

2. Verify all spaces are created properly

3. Verify no errors within Load Analysis window within Revit prior to gbXML file export

Could you please walk me through briefly how to do the 3 steps that you listed? Can you also clarify steps 2 and 3? What constitutes a "properly" made space? How do you check the Load Analysis Window for errors?

For Energy settings:

Go to Analyze Tab of Ribbon, Energy Optimization Panel, Energy settings icon...specify settings such as Mode, advanced (edit).

Alternatively, you can go to Manage, Project Information, Energy Settings...edit.

Go to View Control Toolbar and expand Sun Settings...click Still Solar Study to access Location...specify location of project

For Spaces

Each space in revit has properties such as length, width, height, cfm data, etc.  When you place a space, ensure it is fully enclosed within the area you want (i.e. bathroom with 4 walls).  Verify your height for your space is set correctly too (up to ceiling?, up to structure?, plenum space?).  Specify the space properties such as type of space.  Ensure you create zones for your building and assign the spaces to the zones.

 

For Load Analysis Window

Go to Analyze Tab of Ribbon, Heating and Cooling Loads, Details Tab, expand zones/spaces...make sure no yellow exclamation triangles show up.  If they show up, select one and click yellow warning icon to get info on what is wrong with space...fix each space.

Run analysis again...
