Abstract
There have been carrying many studies to investigate the underlying causes of weathering damage to wood at Buddhist temple buildings, including all their wooden buildings. But the methods of their studies were not carried on the view point of the micro climatic changes such as temperature and humidity, which were the underlying causes of weathering damage. So this study aims to identify the characteristics of air flow inside Hwaamsa Temple site, which is built on a mountain, and whose buildings are different physical levels with their pillars of varying heights. To carry out this study the field measurement of factors (temperature, humidity, wind speed and direction) were measured and their data were analyzed with the computational fluid dynamics (CFD). Based on the results of measuring changes data in temperature and humidity as two inside locations and five locations outside of the temple. As the result the inside temperature and humidity in the Geungnakjeon was evenly distributed, whereas that of the outside was unevenly distributed depending on the location. To a great extent, the speed of wind affects humidity. In the case that the Myeongbujeon in the temple were demolished, there has been a 20-30% increase in the wind speed near the Geungnakjeon Such an increase in the wind speed is thought to affect factors such as the wooden material by stabilizing changes in humidity near the temple.
