A few questions for our readers!

Are you an energy modeller working in the early design process of a building?
Do you have experiences with the IDP (Integrated Design Process)?

There are the following workflows/ options for energy modelling in the early design process:
1. Revit -> gbXML -> GBS (Green Buiding Studio) – Web Service
2. Square One – Ecotect
3. IES (Integrated Environmental Solutions) – VE (Virtual Environment)
4. SketchUp -> EnergyPlus Energy Design Plugin

Who uses them and what are your experiences?
Do you use something else?

It’s new terrain, so some discussions of what is happening might be helpful for many!
