In the climate chamber, individual factors such as sex, age, and metabolic rate are set as experimental variables, and thermal comfort is assessed by measuring physiological indicators such as skin temperature together with subjective thermal comfort responses. 

Thermal response measurement in young adults under different metabolic rates 

Thermal response measurement in older adults

We investigate how indoor environmental quality influences cognitive performance, concentration, and the perceived productivity of occupants. 

Electroencephalogram (EEG) measurement under different work environments 

Thermal comfort and productivity assessment in an actual office environment 

We collect both physiological measures such as skin temperature and subjective questionnaire responses in vehicle cabins, and develop models that predict occupants' thermal comfort from them. 

Evaluation using a thermal manikin 

Evaluation with human subjects 

We study how the thermal and air quality conditions of a bedroom affect sleep quality, and track the physiological responses that occur during sleep.
