Energy Analysis Won't Run

[huick2]

I have my fully created 3D model, Which has conceptual mass and the mass floor. Also I created the energy model of the mass, but when I run "Create Energy model" It keeps telling me 

"There are no visible Masses in the current View.

Either create a mass or adjust the visibility of an existing Mass and try again."

Create Mass Floors.

[huick2]

Yes, I already created the mass floor (see the attached image), but still can't run the energy analysis

Post your file here.

Try these:

1. Choose Conceptual Mass and Building Elements even though you only have Mass.

2. Choose Conceptual Mass only > Create Energy Model > Generate

Thanks in advance

I just want to sim the mass instead of the building elements.

Because building elements cannot apply the detail model parameter in energy setting dialog box.

[huick2]

I think this is a different case because I just want to run a energy analysis of conceptual mass model. Not building element.

Then use the option 2 I posted above.  It works as shown by the analysis result screenshot.

Works Fine. Conceptual and Building Elements.

[huick2]

So means revit cannot run the report by itself? Must be generate the report by insight?

Correct.

Many thanks.

But is it normal, or it's a bug of revit😅

It is by Design.  You create a model in Revit, generate an energy model from it, and push it to Insight to run analysis.

But why the system analysis cant apply in  "Use conceptual mass" ?

I searched the relevant tutorial video on internet and those video showing this function is OK. (Say 2014 version)

Use Conceptual Masses: This mode is used with legacy workflows. This mode is provided only to support older models. Some advanced energy settings relate only to these legacy modes; those settings are unavailable when the mode is set to Use Conceptual Masses and Building Elements. See Create the Energy Model: Massing.

Many thanks for the explanation.

Is it possible to change the Revit 2020 to legacy mode?
