Its not great news is it?
What do you think the chances are that it will become built into revit completely, and nothing but autodesk products will be be able to use it in the future (regardless of what they say).
I really hope the new version of Ecotect, when it arrives in a month or so, will work in a more integrated and user friendly way with ArchiCAD . It is of little use to the average architect when you need a degree in environmental science to correctly input the data, and understand the output.
Autodesk have correctly predicted that accurate environmental modelling will be even more essential in these increasingly carbon-aware times. If they can seamlessly integrate it into revit and get it to give 'good' data they will be on to a winner.
Fully Automated SAP calculations could be particularly useful, and live feedback of how changing an elements thickness effects the rest of the building will surely help revolutionise the construction industry. I thought this is what BIM was meant to be about.
