Conducting a thermal study by using imported 3D geometry as a guide for creating new native zone geometry.
These following steps are covered in the tutorial:

Step1: Exporting the Revit model and importing into Ecotect
Step 2: Modelling the shell in Ecotect using the Zone tool
Step 3: Modelling the shell in Ecotect using the Plane tool
Step 4: Modelling windows in Ecotect
Step 5: Applying and defining Materials
Step 6: Location, Orientation and loading Weather Data
Step 7: Thermal Analysis Calculations
Step 8: Thermal Analysis Charts

I am curious to see how this workflow compares to using gbXML as a translation file between Revit and Ecotect. Has anybody gone this route so far, what is your experience?
