Yes, I'm sure those are at least double pane. Modern windows (especially high end) can be both energy efficient and nice looking. Same goes for their concrete walls--its quite likely that they have insulation in wall cavities or embedded directly in the concrete itself. That being said--I'm sure it still costs a pretty penny to heat in the winter. Its just probably not as bad as you might think.
