I know this an an old "Wishlist" item however being able to export the basic wall/space geometry to a GBXML file would open up a ton of doors for me personally.

Currently, I use Autocad MEP to draw my spaces/walls/geometry & windows and then I export that to a gbxml file into my load calc software (CHVAC). Chvac pretty much ignores all thermal properties and only uses the space geometry and maps any walls/windows to default windows etc. I usally make small changes in CHVAC and then I can export this to other programs for modeling as required.

The gbxml schema appears to be pretty basic overall.

This would be a HUGE benefit.

On the residential side, I can perform a load calc in RHVAC Software, export a *.txt file of the data, save as an *.enb file, and import into EnergyGauge USA (Florida's energy calc software for residential projects). Aside from a few additional inputs, the energy calc is complete.

To reiterate what Brody said below, now I am entering the same information into the EnergyGauge Summit (Florida's energy software for commercial projects) that I just entered into DesignMaster.

Comment from Brody on a different idea I merged into this one:

Anybody who uses your product to engineer building systems currently has to build a parallel model of the building for energy code compliance documentation generation purposes. Y'all already have a lot of the input categories and types a DOE2.2 input file would require in your BIM. Finding some kind of common currency with other BIM software for easy compatibility is tough in some cases, but here you can straight-up use the DOE2.2 input file format.

I'd wager good money that you'd need more manpower to get a feature set this big done, but it conceptually dovetails so neatly and captures a neighboring market populated by customers you already have - it might be worth it, perhaps as an add-on package? Maybe you partner with another company that's already writing a pretty front-end to DOE2.2? Bottom line is: having DM be able to do full ASHRAE 90.1 Appendix G/LEED Title-24 equivalent calculations and spit out meaningful papers would be a *gigantic* value-add.

This would be a useful tool for getting building geometry into various energy modeling programs after load calcs are complete.
