| Abstract | Multizone models provide a relatively simple, rapid
means for simulating airflow and contaminant dispersion in
complex buildings. However, an untuned model may not agree
well with the actual performance ofthe building it represents.
An efficient method for tuning a model, which combines a
heuristic approach with factorial sensitivity analysis, is evaluated
for the case of a hypothetical single-story building
served by three independent air distribution systems. A
detailed "virtual" building model is constructed using multizone
modeling softv^are and a set of design data and then
detuned by changing airflows, flow resistances, and other
parameters. A multizone model of the virtual building is
constructed using the same design parameters and is tuned by
successively correcting its parameters to match values from
the virtual building as directed by the sensitivity analysis,
which uses the percentage of incorrect interzonal flow directions
as the response variable. The method results in improvement
from 60% incorrect to 10% incorrect after six correction
steps. Improvement ofthe model is confirmed by application
of ASTM Standard D 5157-97 for four different simulated
tracer release scenarios. Improvement is significantly more
rapid using the structured approach than when corrections
are made using randomly selected measurements. |
