초고층건물의 연돌효과 저감대책의 정량적 특성검토

The stack effect in high-rise buildings is more remarkable with the building height is higher and higher and the temperature difference between outdoor and indoor space is larger. Moreover the stack effect can be brought about the deterioration of many kind of problems. In this study, as a measure to attenuate the stack effect, the E/V shaft cooling method was proposed and the performances were compared with the conventional stack effect control method as strengthening the building air-tightness by numerical simulation method. The total decreasing ratios on the draft in a building were mainly compared with each other, and the probabilities of the secondary problems and the leduction effect on ΔP at each wall of the building were analyzed also. The results show that the E/L shaft cooling is very effective as the measure to decrease the draft and ΔP in high-rise building. Also, this method does not cause the secondary problems such as stack pressure transition to other walls as shown in conventional stack effect decreasing method.
