ASHRAE, the American Society for Heating, Refrigeration and Air Conditioning Engineers just issued a grant to Texas A&M for “ensuring that a common language of ‘energy efficiency’ is spoken by the both building information modeling software used by architects and energy analysis and simulation software”. I have not played around with Ecotect or IES enough, but I know it had required separate 3D modeling outside of standard BIM authoring software, getting to a point of seamless data exchange you would think would be a starting point not the end point, but glad we are moving that way.
