Thermal comfort and the influence of dress culture analysis based on temperature humidity index in Pontianak

Abstract

In recent decades, global warming has resulted in rising temperatures worldwide, including in equatorial regions. Pontianak, situated precisely on the equator, faces environmental challenges such as high rainfall, frequently exceeding comfort tolerances in air temperatures, intense solar radiation, and persistent high humidity, impacting thermal comfort. The primary goal of this research is to evaluating thermal comfort conditions in Pontianak, primarily utilizing the Temperature Humidity Index (THI) as a key indicator. The study also investigates the influence of local dress culture and clothing choices on thermal comfort. To further measure the level of thermal comfort in Pontianak, the Temperature Humidity Index formula developed by Nieuwolt was employed. The analysis revealed that, on average, the THI during daytime was 32.87°C, indicating some discomfort perception. This is consistent with the opinions of the local community, who often express discomfort with the thermal conditions in Pontianak. These conditions also affect the clothing choices of Pontianak’s residents. Factors such as material, size, and color are among the main considerations for selecting clothing. Nevertheless, the selection of clothing ultimately depends on the body’s response to the thermal conditions in Pontianak, aiming to minimize the impact of the prevailing thermal conditions.
