MattAdl,

Light enters from the top via the sun, plus artificial lighting which is monitored to maintain light levels, with the internal walls likely being insulated and reflective.

If you were to pick holes in the idea you should have said something along the lines that unfortunately given the suns pathway it is not likely that all walls would/could move with the sun to substantiate doing this however the would be some potential there in correct design. Pyramid/angled external shape would be a starting point maybe

Something like that but yeah unlikely worth the trouble
