Abstract
This paper discusses the complex problem of measuring occupancy to better manage large buildings and their energy consumption profiles and explores ways that occupancy has been measured in the past. The paper then explores a novel way of measuring occupancy using a Doppler radar based occupancy sensor, TruePODS, to detect human presence, and the greater implications that this technology provides. As a proof of concept, six TruePODS modules were deployed in a single building on a university’s campus over a period of six months. This paper details this case study and the methods used to empirically collect occupancy data for energy management. This paper concludes with exploring why Doppler technology could provide the answer to creating a high-resolution smart occupancy sensor that would be necessary to meet local and global energy efficiency goals.
