Thermal Comfort Assessment
Résumé
Thermal comfort is a subjective concept, which describes a person's state of mind in terms of whether he/she feels hot or cold. The thermal comfort feeling is influenced by environmental and personal factors. Its most commonly used indicator is the air temperature, which, alone, is not a valid indicator of thermal stress. Thermal comfort should be measured by the number of people complaining of thermal discomfort. There are several procedures to assess the thermal comfort, but they require the measurement of many variables. This paper aims to propose a procedure to assess the thermal comfort. This proposal includes the creation of a ratio scale and a set of statistical procedures to treat the data gathered from this scale. This procedure was used to evaluate the influence of fans in the thermal comfort feeling of the occupants of a small office, and it proved to be useful. This procedure makes easier the inclusion of the human in the control loop of the comfort systems.
