Buildings consume 40% of global energy, yet up to 30% of this consumption occurs in unoccupied spaces—a staggering inefficiency that people counting sensors can eliminate. These sophisticated detection systems, ranging from passive infrared to advanced AI-powered cameras, automatically adjust lighting, heating, and cooling based on real-time occupancy data. Companies like Ariadne have demonstrated measurable results: their installations achieve 20-35% reductions in HVAC energy use by precisely matching environmental controls to actual space utilization.
The technology works through multiple …
