Nor should they have been, since that's not usually dependent on a building's design. But when a poorly-designed HVAC (whatever part of the HVAC) caused a lot of the space conditioning to be born by the plug load, that's not good.
It's true that ground-source heat pumps work great in the majority of cases, and I'm sure it will here, too. It will be neat to have a unique building like this at this spot.
My guess would be poorly designed HVAC systems. Half the buildings I've worked in have had very poor HVAC systems. The one I work in now has temperature differentials of 10 degrees between some rooms. And I've never been in a building with anything besides traditional chillers and natural gas heaters.
