Exposed wall area

[JoelLondenberg]

I'm currently doing wall area takeoffs for energy calculations (boo for California requiring me to use EnergyPro).

Is there any easy Revit equivalent of the AutoCAD process of drawing closed polylines to query for area???

Or maybe this should be a wishlist post???

You can compile the area info quickly by scheduling the rooms/spaces/zones in revit.

Are you talking about wall areas or floor areas? I've had very limited success with creating spaces and doing a gbXML export/import in to Trace. I'm not sure what EnergyPro's capabilities are. It seems to easy to mess up or miss a space and if it's a bounding space you create problems all around it. Scheduling areas would seem like an easy thing to do.

Floor area is easy, I want wall area. As in a wall is 10 feet tall and 30 feet wide for a total of 300 square feet of wall area. But for irregular shapes.

... I'm not sure what EnergyPro's capabilities are...

It's 100% manual data entry, no gbxml related functionality.

That would be a nice feature!

You could do a Material takeoff of the walls. There is a parameter for Material:Area.

You would have to do this in the Arch model file in order to see which wall is which from the the schedule because if you schedule from the linked file you cannot pick on a wall and select "Show".

Thats an interesting idea dmb. I am in the same boat as Joel, having to use EnergyPro for T24 Calculations. Personally I have wish we could just use the prescriptive method for T24, and then trace for loads, but that would just be too easy. With LEED requirements and so forth that is impossible.

Joel, if you figure any method for this please let me know. I wonder if there are any third party apps out there for this yet?

Can this also account for the portions of the wall that are interior vs exterior? What about an exterior wall that extends above the roof as parapet? The portion above does not contribute to the heating/cooling loads.

Use a filled region or masking region to quickly trace the shape then the area is in the Properties dialog.
