In the post we will explore the way Window to Wall Ratio (WWR) is derived when both Revit walls and mass elements define the Energy Analysis Model (EAM). In the previous two ports we looked at each separately.
The image below shows the model used in today's post. The same model with walls from the previous post along with the a mass element added to represent an addition.

To use both Revit elements and masses in the EAM the Energy Settings dialog must be accordingly as shown in the image below.
|Tell Revit to use masses and building elements to create the EAM|
Also in the Energy Settings dialog, the WWR can be set. This only applies to the mass element.

- FYI: of course the mass element does not know how there will be a parapet so the wall area and WWR are off a little.

When pushed out to Insight 360 we see the BIM Setting matches what we saw back in Revit.

In addition to what was defined within Revit, Insight allows the overall WWR to be adjusted for each N/E/S/W face. Simply adjust the sliders to define a range until you are more confident in a specific value. While defining a rage, the Cost/EUI listed is the mean value.
One final note... as a test to see if I could, this entire post was created from my iPad. Everything, except the screen captures. I added the mass element in Revit, created the EAM and used Insight 360 all on the iPad.
