Abstract
Computer-based systems and methods characterize indoor air quality in a particular building having multiple locations therein. The system comprises a back-end data center, at least one indoor air quality sensor located inside the particular building, and a graphical display device. The indoor air quality sensor(s) transmits time-stamped air quality readings collected by it to the data center via a computer network. The data center computes spatiotemporal air quality measures for the particular building based on the time-stamped air quality readings from the indoor air quality sensor(s) and transmits the computed spatiotemporal air quality measures to the graphical display device for display to the user/resident.
