[Bldg-sim] Boiler parasitic energy

[Jim Dirkes via Bldg-sim]

p.s., I've read 90.1 MANY times and never noticed that till a GBCI reviewer

Choice. It is perhaps the most distinct and dignifying characteristic
of humans. Consciously and with understanding, we choose what is true,
honorable, right, pure, lovely … or otherwise. Like the rest of
humanity, my choices don’t always align with true, honorable, right,
pure, and lovely, but I know those are what I set my sights upon. I
choose them.
