In
general, current Building Energy Simulation Tools are used for pre-construction
design and comparison of designs rather than a full exact varying
representation of reality. To provide the best level of detail full CFD
analysis for the entire building would be required. However this is currently
by far outside the scope of current computing power and labour efforts for a
building energy system. Because these simulation tools are designed for
comparison of potential designs and because of the difficulty in predicting
occupant behaviour, very often the predicted results do not correlate with the
real actual performance when buildings are in operation. This paper describes a
methodology being developed to combine building energy simulation results with
accurate and real sensor & meter data with the purpose of better
understanding the relationship between energy simulation and real building
operation for better occupant comfort and more efficient operation.
