| Summary: | Thermal comfort research in Indonesia is known between 23 C and 25 C for dwelling buildings. As tropical weather is characterized by high humidity, high temperature, and intense solar insolation; therefore, traditional tropical housing is predominantly dependent on natural ventilation and passive cooling for thermal comfort. In the literature and practice, there is a gap in knowledge on traditional Banjar vernacular housing. Therefore, a thermal comfort field identification survey was conducted in the Balai Laki House one of the 11 types of traditional Banjar, which included information on the use of building space layout. The measurement results concluded that the category of thermal comfort is in the comfortably warm range, with the THI (Temperature Humidity Index) temperature range between 26,24 - 27,06 C. In addition, the upper threshold for comfortable warm conditions is indicated range of 27,29 - 31,28 C. The results revealed that the efficacy of traditional passive design techniques would not be sufficient to achieve thermal comfort in the predicted future climate scenario. For this reason, the authors suggested that the passive design techniques of Banjar vernacular housing need to be improved, with innovative solutions in order to cope with the changing climate.
