Calculating Building Area in Revit: Gross vs Rentable Area

Revit vs AutoCAD

Revit

3D BIM model with embedded data — single source of truth.

AutoCAD

2D drafting — fast for details and as-builts.

Coordination

BIM excels at clash detection and multi-discipline coordination.

Documentation

Revit's auto-updating views beat AutoCAD's manual workflow.

Master Revit at Noble Desktop

Noble Desktop's Revit Certification Course teaches BIM modeling, families, schedules, and the full Revit workflow used by architecture firms.

This lesson is a preview from our Revit Certification Course Online (includes software & exam). Enroll in a course for detailed lessons, live instructor support, and project-based training.

In this lesson, we're going to go ahead and take a look at a couple of different ways that we can compute area by using the tools that are available to us within Revit.

In this lesson, we're going to go ahead and take a look at a couple of different ways that we can compute area by using the tools that are available to us within Revit. So the first thing we're going to do is we're going to take a look at calculating the gross building area, which is essentially going to use the exterior building envelope as our boundary and calculating the area for level one and level two. And then we can take that same area and create a schedule to display it here.

The next thing we'll do is we'll take a look at rentable area, which is going to only include the different spaces that would be considered rentable. We'll break it out from common areas like the lobby, the restrooms, and the stairwells, and then we'll also calculate the office areas and put it into a schedule.

And of course, just like everything else, we're going to go ahead and finish it out by putting it on a sheet that we can include with our final assignment.
