The document summarizes research on thermal comfort conducted in Mayestik Market in Jakarta, Indonesia. It describes the market's renovation in 2012, existing conditions, data collection methods, and results of thermal votes and preferences. Fifty respondents provided data on gender, weight, age, height, air temperature, relative humidity, and air velocity. Thermal comfort models from ASHRAE and Bedford were applied, with comfort temperatures of 31°C and 29°C respectively. While air temperatures reached 30.5-35°C, most respondents felt neutral or comfortable, though 25 preferred cooler conditions and 24 saw no need for temperature change.

International standard, ISO states that there are six combination variables which are believed to
establish the human comfort condition, i.e. Air temperature, mean radiant temperature, relative
humidity, air velocity, man activity level, and clothing type, and the six factors affecting thermal
comfort are both environmental and personal.

temperature, but the majority of respondents indicate that they feel neutral
(ASHRAE) / comfortable (Bedford).
