Abstract:
The use of multizone airflow and contaminant dispersal
models requires a range of data. In terms of airflow
analysis, these data include leakage characteristics of
airflow elements, wind pressure coefficients,
ventilation system characteristics such as duct losses
and fan curves, and schedules for openings and
ventilation systems. Contaminant dispersal analyses
require contaminant source information, filter
efficiencies, reaction and deposition rates, and
schedules for elements such as sources and filters.
Acquiring such data can be a major part of an analysis
effort. In order to facilitate the use of multizone
modeling techniques, a database containing many of these
inputs has been developed. These data are not
comprehensive in terms of the needs of any given user,
but they do contain a range of the data that are
available at this time. However, the analysis of a
specific building always requires input data that is
relevant to that particular situation. In addition to
the data presented in this report, other sources of
model input data are described.
