Effectiveness of Automatic and Manual Calibration of an Office Building Energy Model
2019
Energy reduction can benefit from the improvement of energy effciency in buildings.
For this purpose, simulation models can be used both as diagnostic and prognostic tools, reproducing
the behaviour of the real building as accurately as possible. High modelling accuracy can be achieved
only through calibration. Two approaches can be adopted—manual or automatic. Manual calibration
consists of an iterative trial and error procedure that requires high skill and expertise of the modeler.
Automatic calibration relies on mathematical and statistical methods that mostly use optimization
algorithms to minimize the difference between measured and simulated data. This paper aims to
compare a manual calibration procedure with an automatic calibration method developed by the
authors, coupling dynamic simulation, sensitivity analysis and automatic optimization using IDA
ICE, Matlab and GenOpt respectively. Differences, advantages and disadvantages are evidenced
applying both methods to a dynamic simulation model of a real offce building in Rome, Italy.
Although both methods require high expertise from operators and showed good results in terms of
accuracy, automatic calibration presents better performance and consistently helps with speeding up
the procedure.
