The Thermal Discomfort Index (TDi) can be used in research examining how environmental factors impact thermal comfort. For example, TDi can be used to compare the impact of different factors, such as temperature and humidity, on thermal comfort levels. Additionally, TDi can be used to evaluate the effectiveness of interventions, such as ventilation systems, for improving thermal comfort in a particular space. TDi can also be used in surveys to measure the thermal comfort of a given population. Finally, TDi can be used to inform strategies for reducing the risk of heat-related illness, such as by identifying high-risk areas where additional mitigation strategies may be needed.
