Siliceous shale from the Wakkanai formation shows quite high performance of humidity control compared to another natural porous materials from cost effectiveness point of view. The Wakkanai siliceous shale can be adapted for building materials in particular since it shows the high capacity in both adsorption and desorption even at normal temperature and humidity conditions.The effect of humidity control is demonstrated in a testing room with a floor area of 7.5m^2. Gypsum boards or plaster painting, in which the Wakkanai siliceous shale is mixed in 1.92kg/m^2 or 0.68kg/m^2 respectively, can be applied for one side of inner walls of 23.2m^2. Both the wall conditions show more stabilized humidity than another condition with normal gypsum boards in some experiments in which humidification and dehumidification are repeated every six hours.Numerical simulation predicts the reduction of mold generation in the humid rainy season by use of such building materials with humidity control. Risk rate of mold generation can be reduced more than 90% in one calculation with the weather data of Tokyo.Adsorption of VOC gases can be observed in rocks and tiles with the Wakkanai siliceous shale by measurements with a chamber of 20 L in a closed system at constant temperature and humidity around 25℃ and 50%, respectively. The characteristics of breakthrough are also measured with ammonia gas in 25ppm by using an adsorption glass column in an open system. One result shows that 2.11 mg/g of supplied ammonia gas is adsorbed in rocks of the Wakkanai siliceous shale in the column at a removal rate of 20%, which is equivalent to 30 times larger amount of adsorption than that in activated carbon pellets as a standard adsorption material.

与另一种天然的多孔材料相比，Wakkanai地层的硅质页岩表现出相当高的湿度控制性能。可以将Wakkanai硅酸盐尤其适用于建筑材料，因为它即使在正常温度和湿度条件下也表明了增加吸附和解吸的能力。石膏板或石膏绘画分别以1.92kg/m^2或0.68kg/m^2的形式混合Wakkanai硅胶页岩，可用于23.2m^2的内壁的一侧。在某些实验中，两种墙面条件都比正常石膏板的另一种状况更稳定，在某些实验中，每六个小时重复一次性化和除湿性化。通过东京的天气数据，可以在一个计算中降低霉菌的风险率。在岩石和瓷砖中可以通过在恒定的温度和湿度约25°和50％的恒定系统下的20 L腔室进行测量，可以在岩石和瓷砖中观察到VOC气体的吸附超过90％。还通过使用开放系统中的附加吸附玻璃柱在25ppm中用氨气在25ppm中测量突破的特征。结果表明，2.11 mg/g提供的氨气被吸附在塔中的Wakkanai硅胶页岩的岩石中，以20％的去除率为20％，这相当于作为标准添加吸附材料的活性碳药丸中的30倍的添加量。
