Indoor Environment during Extreme Weather Events
Wildfire Smoke Adsorbed on Indoor Fabric
Indoor fabric surfaces (e.g., clothes, curtains) can adsorb volatile organic compounds (VOCs) in wildfire smoke penetrating indoors.
Simulation of Indoor Wildfire Smoke Level
The impact of window-opening behaviors on indoor air quality and human exposure to PM2.5 particles during wildfires
Thermal Comfort and Heat Stress
Personal Thermal Comfort using Wearable Sensors
A personal comfort model predicts an individual's thermal comfort response.
Unwanted Local Convective Cooling near Feet
The low-temperature airflow at the floor level for displacement ventilation can cause draft at the ankles and lower legs.
Room Vertical Temperature Gradient
A vertical thermally stratified environment improves air quality but also causes local thermal discomfort due to temperature gradient.
