Occupancy detection

Due to its high demands regarding indoor environmental conditions, healthcare facilities are associated with high energy consumption. To move forward towards more demand driven and energy reduced conditioning, information on occupancy and temperature boundary conditions are crucial. Thermography-based systems enable data acquisition regarding both aspects in high local resolution. In this publication, we propose a thermography system that may be used for monitoring of rooms in healthcare facilities.

Knowing the presence or the actual number of occupants in a space at any given time is essential for the effec-tive management of various building operation functions such as security and environmental control (e.g., lighting, HVAC). In the past, motion detection using Passive In-frared (PIR) sensors has been widely deployed in com-mercial buildings and can provide data on “presence” sta-tus.
