If you are using SBEM and SAP these are simplified calculation tools. The simplified method is an alternative compliance path to Dynamic Simulation Method (DSM) in the UK. EcoDesigner STAR is soon likely to be listed as one of the accredited DSM software in UK alongside IES and Tas Engineering. Only then you will be able to produce Official EPC from EcoDesigner... however EcoDesigner STAR features direct BIM-data export to iSBEM.

The simple answer is no, EcoDesigner STAR would only work with Archicad 16 onward.
