Are Occupancy Sensors Used to Control HVAC in Low-Traffic Areas?

When occupancy sensors could slash HVAC energy costs by 30% in underutilized spaces, why do 68% of commercial buildings still rely on fixed schedules? The disconnect between available technology and practical implementation creates a sustainability paradox. Consider this: HVAC systems account for 40% of a typical building's energy consumption, yet 30% of that energy heats or cools empty corridors, storage rooms, and off-peak conference spaces.
