| Résumé | As part of a larger project on occupancy sensing, we collected 5 Hz occupancy detection data (aggregated to the 15-second level) from a commercially-available ceiling-based PIR sensor. Identical sensors were deployed in 28 offices for up to a month per office. Ground truth data were collected simultaneously using a pressure-sensitive floor mat. We evaluated the accuracy (overall, as well as false positives and false negatives) and energy-saving potential in each office with various timeout periods applied post-hoc. The data revealed relatively poor overall detection performance at the 15-second level. Adding a timeout period of 20 minutes produced reasonable false negative performance for the top quartile of offices, but reduced potential energy savings to 65% of the unoccupied time. The results support efforts to improve occupancy sensing in order to garner greater energy savings. |
