Abstract 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, however, there is a gap of knowledge on Myanmar vernacular housing, specifically with regard to the variation in weather caused by climate change. In this paper, the authors review passive design techniques used in Myanmar vernacular houses to achieve thermal comfort. Using an experimental design approach, simulation studies were carried out to compare the impact of various passive design techniques on thermal comfort in three Myanmar climates. Different passive design techniques used in the two houses were further reviewed. Fifteen models were generated through an evaluation of the latter to examine the thermal performance of Myanmar housing throughout a year, with typical weather and predicted future climate scenarios. 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 Myanmar vernacular housing need to be improved, with innovative solutions in order to cope with the changing climate.
