Abstract

The amount of the leakage area in the envelope of a house should be investigated for the purposes as follows : 1) to estimate more accurately the infiltration ratio due to the wind force and the sttack effect, 2) to design the ventilating system properly, 3) to know the envelope component which should be air-tightenned at retrofitting. Then, this paper, at first, reveals the published researches referred to the air-tightness of houses. Secondly, the air-tightness of various types of 25 houses are investigated in details, and shown is the distribution of the amounts of the leakage areas among those houses and the ratio of the leakage area of each envelope component to all of them. Thirdly, air-tightness of various types of houses are compared internationally using the value of the effective leakage area per floor area when the indoor-outdoor pressure difference is 1 mmAq. Lastly, in the three apartments which have different leakage areas each other, the indoor pressure decreasing and the exhausted air volume are measured in relation to the diameter of the duct for intaking the outdoor air. And on the basis of the result, indicated are the important points for the design of the ventilating equipment in the air-tight house.
