[BLDG-SIM] Validation of simulation predictions

[Bill Koran]

Validation of simulation predictionsI participated in the calibration of
simulations of commercial buildings as part of the BPA Energy Edge research
project in the early 90's.  The buildings included high-rise office, small
office, fast food, and supermarket.  The models were calibrated to hourly
end-use data and, to a lesser extent HVAC subsystem data.  For example over
200 channels were monitored for the large office building.  Not all of the
channels were used for model calibration, however.

Amongst the published papers that came out of the research were the
following:

Kaplan Engineering and Portland Energy
Conservation, Inc , (1991). "Energy Edge Modelers Guidelines

Report."

There were also the calibration ("tuning") reports for the individual
buildings.  An example is

prepared for Bonneville Power Administration Commercial Technology Section

under cooperative agreement #DE-FC79-85BP26683



In that calibration exercise, the energy use categories calibrated were
total building, total HVAC, total interior lighting, receptacle plugs,
elevators, and parking garage.  Within HVAC, energy for heating, cooling,
AHUs, condenser pumps and cooling tower fans, and chilled water pumps were
individually calibrated.

Can anyone point me to papers that discuss the validation of whole building
energy models (DOE2 or others) with measured building data? I am looking for
papers discussing the accuracy that can be achieved for both simulations
based on comprehensive energy audits of existing buildings and simulations
based on design documents that are then compared to measured performance of
the building after occupation.

Thanks,
