The data was collected through a thermal comfort survey in Djibouti in Markazi refugee camp. The data includes key indoor environmental parameters such as temperature (wet bulb temp, air temp, glob temp and operative temp), air velocity and relative humidity. Moreover, the dataset contains information about the metabolic rate and Clo value, TSV and TPV of the survey participants. The data was collected via a thermal comfort survey, including spot measurements of environmental parameters, the surveys were conducted directly in the Arabic language. The families were selected randomly. Given the range of backgrounds, intra-household dynamics, education and literacy levels, all surveys were administered through an interview. A repeated transverse survey method was used to collect the data. The thermal comfort scales were the standard 7-point ASHRAE thermal sensation scale and the 5-point thermal preference scale
