Various construction method were applied to prevent the condensation on the wall and floor of under ground space in apartment buildings. However the surface condensation is not prevented completely, it is caused by high percentage of relative humidity. The result of field measuring, the relative humidity of underground space reached on 99%. In this case, it is necessary to apply the humidity control method for preventing condensation. In this study, we considered using the inorganic finishing material that consists of cement, water and admixture like concrete as humidity control method. Also we considered dehumidifying system that could be applied to stair case and elevator hall of underground. To evaluate the humidity control capability of inorganic materials and the dehumidifying system, we performed the field test on underground space in apartment buildings. As a result, the permeability of inorganic materials that applied to the wall and floor is useful to prevent the condensation of underground space. In small space such as stair case and elevator hall, applying dehumidification equipment is more useful. Also blowing dehumidified air from stair case to parking area can decrease the humidity of underground parking space. |
