most of the issues the building experienced are due to the fact that the state value engineered Jahns design and didnt use the proper glazing on the panels, right? and in general, they didnt keep up on maintenance.

also, there are lots of designs that are "inefficient" that are considered landmarks in architecture. the definition of sustainable/efficient changes over time. is Union Station's Great Hall an efficient design? well, no. im sure the modern addition with drop ceilings and narrow corridors and no grand spaces is more efficient to heat/cool. you tell me which youd rather have preserved.
