In the same way gbXML is not built for and can't handle this kind of buildings. If you look at the gbXML specification today it might work for dimensioning hvac and mep equipment like heaters, radiators, coolers, boilers, ventilations units etc.
We know that the gbXML spec is not working for energy calculation under normal Scandinavian circumstances and with solution that build on natural ventilation and cooling. We also know that the specs seems to work under"normal USA conditions" thin insulations and when you control room temperature with heaters and coolers. But somewhere along the line gbXML stops to work as a information (data) transport solution.
I think a discussion about gbXML really belongs somewhere else - it doesn't have much bearing on ED. Having cast doubt on gbXML as a transport mechanism, however, I think it's only fair that you provide some solid facts. gbXML was designed specifically to transport building data for green analysis and design; from
gbXML.org:

The Green Building XML schema, referred to as “gbXML”, was developed to facilitate the transfer of building information stored in CAD building information models, enabling integrated interoperability between building design models and a wide variety of engineering analysis tools and models available today
The building fabric, context, and usage is described in enormous detail, including individual room volumes, detailed construction data (layers of materials including doors/windows, engineering data/characteristics, adjacencies), room usage (people and equipment), building occupancy patterns, shading, lighting, plant, etc.
So why do you say "gbXML is not built for and can't handle this kind of building" or "somewhere along the line gbXML stops to work as a information (data) transport solution." What data
specifically
is missing?
