Analytical surfaces and analytical spaces

[vingels]

Hi,

I am working on a workflow for heat load calculations for my company. The workflow of creating an Energy Model seems promising, but due to local requirements, I don't think we can use the Loads reports created in Revit. Here is my plan so far:

1. Create an Energy model based on spaces.
2. Find the analytical surfaces that belong to each space.
3. Export surface areas to Excel for each space.
4. Use local requirements to calculate heat loss in Excel.
5. Import the heat loads back to each space.

This plan may not be ideal, but I think it will work for us. My problem now is to find the analytical surfaces that belong to each space.

I have explored some different approaches, but please correct me if I am wrong:

• The analytical surfaces are "At wall center."
• The spaces/analytical spaces cannot be changed to "At wall center."
• There are no parameters linking analytical surfaces to analytical spaces.

However, I noticed that the areas I am interested in for each space are listed in the Loads report. So how do I obtain these values? I would prefer to get the "element" since we could have different Space Types with different U-values, for example, exterior walls.

I am quite familiar with Dynamo and have tried to find some nodes and scripts without luck…

Not a direct answer but you should maybe explore the Room Book, Area Book, Building Book extension which can extract details of surfaces and materials in each room/space from the building model rather than the analytical energy model.
