Effect of measurement location of air air-tightness performance on apartment units in Korea

The purpose of this study is to evaluate the effects of measuring position of air-tightness performance in Flat-type and Tower-type apartments. Air-tightness performance was measured on entrance doors using the Blower Door System in accordance with CAN/CGSB 149 and on the windows using air-tightness Measuring (KNS-serise) in accordance with JIS A 2201. The air-tightness test was performed with newly builted apartments in 2011. The air-tightness test results on location were converted into ACH50 for comparison. The result on the windows was higher compared to the result of the entrance door. According to the results, the entrance door has greater air-tightness performance than the window which has less air-tightness. In conclusion, it is appropriate to take measurements of air-tightness performance on the windows of apartments in Korea
