[Bldg-rate] achievable accuracy of EnergyPlus or similar programs

[Boris Menin]

Dear colleagues,
1. Do you know the maximum number of variables/parameters that could
be applied in EnergyPlus?
2.May be you have got any information about the preliminary calculated
accuracy (uncertainty/error of, for example, room temperature) of this
program?
Human intuition and experience suggest the simple, at first glance, truth. For
a small number of variables, the researcher gets a very rough picture of
the process being studied. In turn, the huge amount of accounted variables
allows deeply and thoroughly to understand the structure of the phenomenon.
However, with the apparent attractiveness, each variable brings its own
error in the integral (theoretical or experimental) error of
model/experiment. Therefore, would seem, must be some optimal/rational
number of variables specific to each of the studied processes.
Thank you in advance for your cooperation.
Best regards
Boris
