My practice are developing our passive house expertise and as we do our modelling in ArchiCAD we were hoping to make the most of ArchiCADs capabilities in energy evaluation and PHPP export.
Has/does anyone have any guidance on this? best practice/workflow etc. would be greatly appreciated.
Yeas I'm currently trying to decipher ArchiCADs naming for the areas in PHPP, it seems as though there is a fairly large amount of ambiguity between the naming/areas that are exported to PHPP and to understand what is what requires some back and forth!
It would be great if anyone could clarify any of this for me?
It would be good if GS took the lead on this. I am also interested in making this work particularly now the UK government seems to be pushing us even harder into low energy design, unfortunately my previous enquiries in this forum regarding energy analysis and PHPP have proved unfruitful.

For this PHPP compatibility specifically, I got this input from my experts:
"ARCHICAD's Energy Evaluation and EcoDesigner STAR features are not certification or auditing tools for energy evaluation purposes. They are merely a design-aid tool for making energy-conscious design decisions.
With regards to PHPP, we are currently compatible with the PHPP v9 excel sheet. This is an extensive sheet made by PHPP used to certify passive houses which contains a lot of interrelated information. ARCHICAD can export and include some of the information needed for the PHPP certificate, but not everything.
Exporting to PHPP v9 is done directly within ARCHICAD's Energy Model Review palette, given that a proper BEM (Building Energy Model) is formed and a PHPP v9 (or older) excel template is available. When you wish to export to PHPP, a prompt asks to browse for the said PHPP excel sheet."
I hope this input helps a bit.

Regarding the question about DesignPH - the workflow that we have created is to create a morph of the walls, openings, and non-thermal mass, put them all on layers that can be filtered out, and then save to SketchUp. In SketchUp we then add all of the PH-specific information.
It would be great to essentially have a 'DesignPH for ArchiCAD' so that we wouldn't need to have this extra step. I know that you can write directly to Excel from ArchiCAD, but I'm not sure how to do it so that you can select specific cells to fill. I personally don't think that we will ever get to a place where we can just use the walls created for accurate energy modeling, mainly because there are some nuances that we need to do in order to accurately assess thermal conductivity. Creating morphs is the way to go for me.
