There is an interesting and helpful blog post on the BPA Blog about how to use Autodesk Vasari for numerous types of Building Performance Analysis (BPA) including Energy Analysis, Solar Radiation, Sun Studies, Wind Tunnel (exterior airflow) and a few others. Check it out.
For those of you interested in Building Performance Analysis and working with eQuest or Energy Plus there is a very interesting blog post on the BPA Blog about using gbXML output from Autodesk®Revit®, Vasari® or other authoring software and converting it to DOE2 or Energy Plus input files. By using Autodesk Green Building Studio (GBS) in that workflow you can use GBS to fill in a lot of the analysis input data that could take hours to complete by hand. You can find the blog post here.
