| Abstract |
The main thrust of this paper was to evaluate the current status of air tightness in Korean residential buildings using the blower door test approach. A well-known fan pressuriztion and deperssurization test standard, CGSB 149.15-96 was applied to the measurement performed in four different residential buildings located in Seoul, Gyong-gi, and In-cheon. One highrise and one midsize apartments recently built, one 1970's midsize apartment, and one typical two-story house built in mid 1980's were selected for the tests. The blower door test result clearly showed that the air tightness in Korean residential buildings has been improved significantly for the last 40 years. However, it was also found that, since 1990, there has been no more big progress on the level of air tightness. It would mean that the current weatherization technology in Korea has been reached its ultimate level, although one may still found a little gap in the residential air tightness compared with those in other developed countries. |
