Buildings can be fitted, with expensive super-materials, that freeze at night, and thaw during the day, to regulate building temperature. Why not ask employees, to crank open their windows at night (letting cold air in), and closed the next morning; and to dress in layers, that they can shed, over the course of the ensuing work day? Anti-efficiencies can be construed, to "lurk", in many & diverse forms. Cp. stereotypical grant proposals, for alleged "Wonder Machines".
