Revit/Vasari and 123D Catch for Energy Modeling of Existing Buildings

Solar Radiation Tool in Project Vasari

The following videos were posted by Simon Gillis from Autodesk at the Sustainable Design Toolbox to describe in more detail the steps necessary to carry out the Rapid Energy Modeling (REM) of existing buildings. You can see how you can use 123D Catch and Project Vasari or Revit 2012 to create energy models of existing buildings to explore retrofit options.

Some of the techniques used in 123D Catch are pretty nifty, but is it that much better than just using the satellite image from Google that you can import directly into Vasari? Seems to me like this REM workflow was decided before Vasari had the satellite imagery functionality. I personally see the value in the point cloud export from 123D Catch to bring in to Revit and then calculate things like window to wall ratios on individual faces. That seems more useful to me than creating a building footprint Autocad .dwg as the videos suggest. Anyways, you be the judge. Enjoy the neatly sorted videos below and contact us if you need guidance on how to use these tools.
