Desk‐Level CO2 Sensing for Monitoring Occupancy and Indoor Environmental Quality

Indoor Air, Volume 2026, Issue 1, 2026.
Occupants of buildings with poor indoor environmental quality (IEQ) suffer from a lack of comfort, poor work performance, health effects and effects on wellbeing. IEQ can vary within a space, and building occupants both influence and are influenced by this, by generating carbon dioxide (CO2), heat and moisture.

Dynamic Airflow Patterns and Directional Effects on Human Thermal Comfort: Evidence From a Controlled Chamber Study

Indoor Air, Volume 2026, Issue 1, 2026.
Despite growing interest in airflow‐based cooling, the combined effects of airflow mode and discharge angle on human thermal comfort remain systematically unexplored, particularly under hot–humid conditions. This study presents a controlled chamber investigation that jointly examines airflow mode and discharge angle within a unified experimental ...
