Save-On utility bills (not)

This is a bit like the solarium design that fast food restaurants used to have too. It's too bad that sort of architecture is quickly disappearing around here, generally due to the impact on HVAC costs (especially AC in the summer, since that's something that's a problem now in ways it never used to be and most older buildings don't have good enough AC to deal with summer heat any longer, if they have AC at all). The angled-out sign above the doors adds to the retro look here -- I wonder how much of this PriceSmart will change, if anything.
