Our team is developing a new exploratory data analysis tool for the Center for the Built Environment (CBE), a research group at the College of Environmental Design (http://www.cbe.berkeley.edu). One of CBE's research projects, the Occupant Satisfaction Survey, uses an online survey to collect data regarding occupant satisfaction in relation to a variety of metrics (such as air quality, acoustics and lighting) in various buildings. As a supplement to their current reporting capabilities, ArchMiner is intended to enable dynamic exploration of the data collected by the survey. By combining the familiar cross-tab format with the charts used in the reporting tool, we hope users will be able to visually compare question responses within as well as across datasets. This will allow them to more easily investigate hypotheses and observe trends in building occupant satisfaction with respect to various building technologies.
