Hello, I use Designbuilder and I have done all the HAMT settings for an individual material (indoor plaster) and chose "Include moisture transfer settings" for the material (and generated a new moisture transfer setting = "EMPD + HAMT"). For the advanced simulation method I can not choose EMPD or HAMT, but I allowed "individual constructions to override solution method". Now I have 2 different settings for a zone: first is with indoor plaster with low/bad sorption isotherms, second is with high/good sorption isotherms. After simulating I find no differences in the zone relative humidity at all. In the in.idf file I find no section with the sorption isotherms either. So I doubt, if E+ is really using the EMPD+HAMT solution algorithm.
Did anyone use EMPD/HAMT successfully in Designbuilder yet? Thank you and kind regards,
