When creating a conceptualization model in Revit you can now use the same radiation analysis that is used inside the Ecotect platform(not as detailed but good nonetheless). This will enable architects to get a better understanding of how the orientation of their design will be affected by the solar radiation thereby creating a better sustainable design that will consider heating and cooling loads for the life cycle of the building.
Check the link below that will allow you to download this great plug in from the Autodesk labs website.
