The parameter B-value has been known as a criterion for judging humidty control effect of materials used for interior wall.By using this value, we con estimate humidity control ability of the interior wall in the room.In the rresent study, we attempted to develop newly method of measuring the parameter B-value, along with its application to the large wood building.The B-values for almost all materials employed in the experiment were similar to those measured by the onventional method.The new B-values for materials with moisture permeability are different from the result obtained form the convetional method.However, even if materials or their thickness are different, the same B-values were obtained when their moisture permeabilities are the same.From this, we found that the newly developed B-value also applied to marerials with high moisture permeability.In such materials, we observed tgat adhesive laysive layr in plywood acted as vapor barrier.Although temperature and humidity in the measuring box changes greatly outside, The B-values obtained from a diurnal cycle were the same as the conventional one.From these results we may conclude that the newly developed method mentioned above is effective for measuring B-value.

参数B值一直被认为是判断内墙材料湿度控制效果的一个标准。利用这个值我们可以估计房间内墙的湿度控制能力。在最近的研究中，我们试图建立新的参数B值的测量方法，并将其应用于大型木结构建筑。实验中使用的几乎所有材料的B值都与传统方法测得的B值相似。对于透湿性材料，新的B值与传送法得到的结果不同。然而，即使材料或其厚度不同，在透湿率相同的情况下，得到相同的B值。由此我们发现，新开发的B值也适用于高透湿性的材料。在这类材料中，我们观察到胶合板中的Tgat粘合层起到了防潮层的作用。虽然测量箱外的温度和湿度变化很大，但从一天的周期得到的B值与传统的B值是相同的。从这些结果可以看出，上述新开发的方法对于B值的测量是有效的。
