Abstract

Centralized HVAC systems in offices lack granular environmental data at the occupant level, hindering personalized comfort. We introduce COMFORT-SENSE, an IoT-based smart desk hub, that bridges this gap by creating a comprehensive sensing ecosystem and integrating local devices with centralized systems. The system enhances HVAC control through an innovative sensor array capturing temperature, humidity, light, and indoor air quality (CO2 NH3 NO2) while reporting usage and occupancy data. This multi-parameter approach advances beyond existing single-parameter feedback systems. Initial validation with 21 participants focused on temperature setpoint and local air velocity interactions. Results demonstrated highest user satisfaction at 75°F with 0.5 m/s air velocity, optimal comfort was achieved at 78°F with 0.15 m/s air velocity compared to baseline comfort at 73°F without airflow, indicating potential energy savings through elevated temperature setpoints. Though current validation focused on thermal comfort, COMFORT-SENSE provides a framework for next-generation adaptive building control systems.
