[Bldg-sim] Chiller Efficiency

[amit bhansali]

Well, the baseline COP are measured at standard testing conditions. So i am
not debating the fact the COP would be constant. I just needed to know that
what does increase in 25% efficiency actuallu mean. I personally thought
having a chiller whose kw/ton was lower than that recommended  by ASHRAE
90.1 would be good. Needed to confirm that.

Thanks  for the input
