Yesterday saw the release of Autodesk's Project Falcon add-in for Revit. This is a tool which has been in testing for a while as a stand-alone tool or connected to other software packages such as Inventor, via Autodesk Labs. Project Falcon is a wind tunnel / wind analysis tool which can be used to generate an accurate air flow simulation around your model / building model. Some of the tools you will see in this add-in may look familiar from the energy analysis tools inside of the now graduated Autodesk Vasari.
