This paper thoroughly investigates vernacular housing designs and evaluates on the aspect of building physics. A new research methodology which is adapted to the natural and social context of Vietnam was proposed and applied. The process was carried out step by step, including: climate zoning, systematic analysis, in-situ survey and building simulations. The results of this study indicate that vernacular housing in Vietnam is creatively adapted to the local natural conditions and uses various climate responsive strategies. Through this study, the most frequently used strategies and their effectiveness were derived. The authors also found that under extreme weather conditions, traditional designs might not be sufficient to maintain indoor thermal comfort.

Introduction In recent years, facing the risk of global warming and of the depletion of fossil fuels, reduction in energy consumption along with sustainable development is a priority for many countries, including Vietnam. Today, we generally acknowledge that the building sector consumes about one-third of the total
