You can transfer BIM models from AECOsim Building Designer into AECOsim Energy Simulator.
Choose File > Export > Energy Analysis to open the Analytical Space Model Explorer dialog where your current design can be interrogated and checked for validity.
Once you are comfortable with the results, click on the Export button and then click Yes if you would like to open the model at this time.
At this point the handover to AECOsim Energy Analysis will take place, with the ASM Energy Settings & Validation dialog opening in front where you can review and/or change settings, accept and close.
Once in AECOsim Energy Analysis you can perform your analysis and modifications as needed, and if desired export to gbXML.
Note that the process is one-way at this time since there is no framework for bringing AES data back into ABD.
