Abstract
In Laos, the research of the relationship between local climate and the building is still less, therefore the
attentiveness of passive design in building is also rare and depreciates. This study will be some basic
guideline for studying about air movement that impact to the building in Laos which has the hot-humid
weather all year. This study analyzes how the physical characteristics of air flow affect to the local
accommodation building in Vientiane Capital of Laos by using Computational Fluid Dynamics (CFD)
techniques. Furthermore, the study aims to investigate the air movement appearance inside the room
influenced by the environment around building, particularly the main factors of human comfort including
the air movement, the age of air, temperature and pressure.
