Data collected in the field as part of the BASE study are coded for confidentiality and stored as a collection of data files or spreadsheets, available in both SAS® (registered trademark of SAS Institute, Inc., Cary, NC) and dBASE® database files (DBF). The BASE dataset is available on CD-ROM and consists of three distinct modules, folders, and data files. One folder contains the environmental monitoring data; another contains the occupant questionnaire responses; and the third contains the building characteristics, and the heating, ventilation and air conditioning (HVAC) characterization and measurement data. The dataset is graphically represented in the table below.

Who Are the Most Likely Users of the BASE Raw Dataset?
The BASE raw dataset will be most useful for researchers, scientists, building professionals, public health officials and policy makers working on indoor environments. Using it will require familiarity in working with a complex dataset characterizing public and commercial office buildings in the U.S. with respect to IAQ and occupant perceptions. The dataset allows examination of possible relationships among building and HVAC features, pollutant concentrations, and occupant symptoms and perceptions. In addition, the data allow for hypotheses development regarding these relationships.

The data have undergone documented quality assurance procedures and all reasonable efforts have been made to ensure the validity of the data. However, it is expected that anomalies may be discovered as further analysis is made. Therefore, EPA plans to maintain a list of all requesters of these data in order to track how data are being used and to be able to provide updates and information on any major anomalies identified.
