You cannot say the same.. this is a false equivalency.
Glass buildings are not possible in the energy code without sham energy models which use "high efficiency HVAC" and other active energy to make up for the passive energy loss due the building having basically no insulation. These energy models also often ignore thermal bridging and assume a perfect installation.
There is a reason the energy code is mandating 40% window to wall ratio. Lots of researchers are pushing for 30%. Unless developers are willing to spend the big bucks on the top of the line windows (they are not willing), all glass buildings will always be an energy suck and are not suited for our climate.
