Currently EcoDesigner exports the Energy Evaluation performed to PHPP 9.6, but export is partial, and some values are calculated differently in Archicad/ED than what PHPP requires. This could be a quick fix/addition requiring few resources on Graphisoft's part. Development of a guide or even a PHPP wizard as a step-wise process in ED would really help a user ensure they have considered everything PHPP is looking for (ie all vertical and lateral thermal bridges) - the workflow is already possible - it is just incomplete. It would be AMAZING to have export parity to PHPP - allowing design optimization right inside ArchiCad, review with EcoDesigner, and finally, export to PHPP for confirming/checking the design and results, and for certification/compliance means. Passive House is the only truly international Energy Standard.

A fully working ED is a must with export in PHPP or integrate EcoDesign in it. The process is a hastle, we end up working in three softwares (Sketchup with EcoDesign, ArchiCAD and PHPspreadsheet).
Hope we see some help from archicad 25, the request for passivebuildings is huge and we lack software development on this area. The world is turning around and we still play with sticks
