Abstract

Indoor air quality (IAQ) models are often used to predict airflows, contaminant concentrations and personal exposures for a given indoor environment. In order to generate such results, these models typically require the user to provide a wide range of input data including envelope leakage information, weather, ventilation system characteristics, contaminant source emission rates, sink removal rates, occupant schedules, and air cleaner removal rates. Many of the required data are available in the literature; however, this information has generally not been compiled in a single database for use in an IAQ model. As a result, finding appropriate model data can be a repetitive and laborious process for the user.To make this effort more efficient, the National Institute of Standards and Technology (NIST) has begun an effort to compile model input data needs into searchable databases. To date, NIST has created a library of airflow leakage elements, wind pressure coefficients, ventilation system characteristics, and ventilation system schedules for use in its multizone IAQ and ventilation model, CONTAMW. The next phase of this work, and the focus of this paper, is the development of a VOC source emission rate database and model library based on thousands of database records that have been collected from published and unpublished data as well as existing VOC source emission rate databases. With these databases, CONTAMW users and other modelers will be able to simulate a wide range of exposure scenarios in different types of buildings as well as simulate potential control strategies. In addition, as a result of this work, it will be possible to identify important knowledge gaps in the data.
