Occupancybased

Occupancybased is an term used to describe systems, strategies, or algorithms that adjust their operation based on information about whether people are present in a space and, in some cases, how many. In building technology, occupancy-based control (OBC) uses real-time or forecasted occupancy data to modulate environmental conditions and services, such as heating, cooling, ventilation, and lighting. Data sources include passive infrared sensors, video analytics with privacy safeguards, CO2 sensors, door counters, calendar schedules, and wireless device presence.

Occupancy data are processed to estimate room or zone occupancy, optionally with predictive models, to determine setpoints or on/off states. The objective is to meet comfort and safety requirements while reducing energy use and peak demand. Applications span commercial, educational, and residential settings, with examples including demand-controlled ventilation and occupancy-responsive lighting.

Advantages include potential energy savings, reduced equipment wear, and better occupant comfort through tuned environmental conditions. Challenges include ensuring privacy and data security, achieving reliable detection in mixed-use spaces, integration with existing building management systems, and initial costs. Accuracy of occupancy estimation and the handling of transient occupancy patterns are ongoing research and development areas.

In other domains, occupancy-based approaches can also influence staffing, service levels, or pricing, depending on the context and data availability. Overall, occupancybased denotes a data-driven paradigm that aligns system behavior with actual or anticipated human presence.
