Differences between EEG during thermal discomfort and thermal displeasure
Building and Environment, 2021Abstract This study used electroencephalograms (EEGs) to investigate thermal discomfort. The thermal discomfort defined in this study considers both thermal displeasure induced by step-changes and thermal discomfort induced by temperature ramping. A total of 108 people in their 20s and 30s participated in the experiments.

Quantitative measurement of productivity loss due to thermal discomfort
Energy and Buildings, 2011Abstract The effects on human performance of elevated temperature causing thermal discomfort were investigated. Recruited subjects performed neurobehavioural tests examining different component skills, and addition and typing tasks that were used to replicate office work. The results show that thermal discomfort caused by elevated air temperature had

Implications of climate change for thermal discomfort on underground railways
Transportation Research, Part D: Transport and Environment, 2014Hot weather events, ventilation assets, changing passenger demand and service expectations have all caused increased attention on thermal comfort on London’s Tube. This study provides estimates of the future number of days when passengers travelling on sections of the Tube could be subjected to thermal discomfort under future scenarios of climate ...

The quantitative assessment of thermal discomfort
Environmental Research, 1969Abstract Discomfort aroused by lowering or raising the operative temperature of a subject's environment was found to follow the “power law” that governs many dimensions in the domain of sensory psychophysics. To a first approximation, discomfort caused by cooling grows as the 1.7 power of shifts downward in temperature from the level that feels ...

THERMAL DISCOMFORT OF RESPIRATORY PROTECTIVE DEVICES
American Industrial Hygiene Association Journal, 1990Respiratory protective devices which would protect the wearer against noxious material and gases are not worn in many of the appropriate circumstances. They have been said to feel uncomfortable and hot. In the present study, six men and six women in a 25 degrees C room reported on facial discomfort, thermal sensation, and sweating while wearing three ...

Thermal Discomfort Detection Using Thermal Imaging
Volume 6: Energy, 2017Effective energy management in the buildings is one of the key factors impacting the overall energy consumption, and thus has important consequences on climate and the environment. Detecting human thermal discomfort can be potentially used to reduce energy consumption in both buildings and vehicles, while maintaining the thermal comfort sensation of ...

Discomfort due to Vertical Thermal Gradients
Indoor Air, 1996Abstract Abstract When 207 subjects wearing their own clothing were randomly assigned to 9 conditions, consisting of 3 levels of vertical thermal gradient (nominally 0, 2 & 4 K/m), and 3 levels of estimated whole-body heat loss (40, 48 & 56 W/m2 as measured on a similarly-clothed and seated thermal manikin, corresponding to warm, neutral and cool ...

Thermal Discomfort Evaluation in Hot Environment
Applied Mechanics and Materials, 2012In this study, the subjective emotion, galvanic skin response and sweat rate of 10 volunteers were examined under different climatic conditions in a chamber. The conditions were 25°Cwith 50% relative humidity, 30°Cwith 90% relative humidity, 35°Cwith 90% relative humidity, 40°C with 90% relative humidity.

Detecting Human Thermal Discomfort via Physiological Signals
Proceedings of the 10th International Conference on PErvasive Technologies Related to Assistive Environments, 2017This paper provides a new approach to the automatic detection of thermal discomfort. We see this research as a step toward the development of an intelligent climate control system that does not require any explicit input from the users. We introduce a novel dataset that simulates different thermal comfort/discomfort levels and we provide a complete ...
