Augmentation parameters: Augmentation parameters are additional parameters that were measured at some of the buildings in the program. Augmentation parameters for the BASE study included nicotine, air handling unit continuous air stream carbon dioxide, acetaldehyde, biologicals in dust, air infiltration rate. Measurements of augmentation parameters were considered for inclusion at selected buildings based on considerations of the research objectives, historical data, integration potential of the measurement results with other studies, and other factors as deemed appropriate by the EPA Program Manager.
Core parameters: Core parameters are parameters for which measurements were required for all EPA-sponsored building studies and meet the following general criteria:
- Provide physical, comfort, or environmental information pertaining to the study area(s) considered necessary for characterizing the overall quality of the indoor environment.
- Employ standard methods that provide measurement data with sufficient sensitivity, selectivity, precision, and accuracy to adequately characterize the indoor environment as it exists in a range of large buildings.
- Employ measurement methods that are easy to implement in the field, create minimal burden on the building space and occupants during monitoring, and are relatively inexpensive to perform.
Detection Frequency:
Fixed site: Four fixed (stationary) indoor monitoring locations and a fixed outdoor monitoring location as close as possible to the fresh air intake of the primary air handling unit (AHU) serving the study space were established in each building. For three of these fixed sites, integrated, continuous, and real-time monitoring was conducted. At the fourth fixed site, only continuous monitoring was conducted. Equivalent sample sets are collected at the three fixed indoor and fixed outdoor locations.
Integrated measurement: Integrated measurement involves collection of samples over a selected (integrated) time period in the field. The collected sample is then sent to a laboratory for analysis. In the BASE study these methods were generally used to collect samples at fixed sites during a nominal eight to nine-hour period equating to the normal occupant working hours. Integrated bioaerosol samples were also collected over an integrated period, but over a 2 or 5 minutes sampling time period.
Mobile site: A mobile cart was used for making measurements at all of the indoor mobile locations. Typically there were five mobile sites, four of which were (?) collocated with four fixed indoor sites. The mobile cart was configured with battery powered, real-time monitors for CO2, temperature, and relative humidity. In addition, the mobile monitoring cart included an airflow capture hood that was used to record the supply air delivery from the air outlet diffuser(s) closest to each mobile monitoring site. Qualitative information related to odors, cleanliness, and noise were collected at each mobile site using a standardized checklist.
Real- time measurement: Methods that use real-time instruments are used to sample and measure the parameter continuously (e.g., sound level, luminance, carbon dioxide, etc). Instantaneous measurements may be recorded or they may be averaged over a designated time interval. When these monitors are portable, they can be moved throughout the study space to perform measurements at several locations.
