[Bldg-sim] Compare simulation results of benchmark models to actual typical building energy use

[Jin Minming]

Dear Michael,

Thanks for your reply. 

I understand that the main purpose of these benchmark models is to provide 
consistency in modeling methods and implementation in commercial buildings. 
There is another report from NREL "methodology for modeling building energy 
performance across the commercial sector":
http://www.nrel.gov/docs/fy08osti/41956.pdf
I am not sure whether there is  a direct connection between this report and 
these reference building models.  But as said in this report,
"For routine or widespread use, we recommend developing smaller sets of 
benchmark models to represent the commercial sector." So I think it is 
reasonable to compare the results of thsese reference models to actual typical 
energy use in different types of commercial buildings although more variations 
of these models need to be created to represent wide range of actual buildings. 
Whether they match well or not,  it may give some clue how the buildings across 
the commercial sector perform as a whole in practise.  Anyway, the results from 
these kind of bottom up methods are usually very hard to be consistent with each 
other.

Jim and all,
 
The DOE reference building models were developed as standard energy simulation 
models that represent typical building practices.  The energy models were 
developed to form consistent starting points for energy modeling exercises such 
as evaluating energy standards (they have been used for 90.1 and 189.1) and 
evaluating new technologies.  They are not meant to represent actual energy use 
of any particular building; however, the results from the models could be used 
as another reference point for comparing energy performance if the model is 
close to your building type.

Dear All,

DOE has developed commercial building benchmark models using EnergyPlus.
http://www1.eere.energy.gov/buildings/commercial_initiative/reference_buildings.html

I want to know whether someone have compared simulation results of these 
reference building models with actual typical USA building energy use (like from 
CBECS database). If so, would you please tell me where I can find these reports?

Thanks a lot,

Jim Terry
