Numerical investigations of Stilt houses natural ventilation and Thermal Comfort Evaluation in Southern Yunnan Province

摘要

For the purpose of improving the effect of natural ventilation and thermal comfort of a traditional stilt houses located in Southern Yunnan Province. The indoor and outdoor wind environment of the existing Stilt houses were simulated by Airpark software, the factors of indoor ventilation effect and thermal comfort were analyzed, and the effects of the size and location of the windows and vents on natural ventilation were analyzed. The results indicated that the size and location of the windows could improve the indoor natural ventilation effect and the indoor air temperature reduced of 2.4°C in summer, while the role of the vent is not obvious. Furthermore, the design suggestions and strategies for enhancing the thermal comfort of a traditional stilt house located in the Southern Yunnan Province were presented.
