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.
