Ventialtons in Air-tightened HouseTraditional wooden house in Japan had been adapted to humid climate in summer and had excessive ventilations throughout the year. It became deep-rooted custom to heat only a part of the house in winter and succeeded to the present where the air-tightness of the houses are increasing rapidly. Under these background, following studies had been done by eight research members.1. Air-tightness of actual houses2. Distribution and fluctuations of indoor temperature, humidity and <CO_2> concentrations in actual houses3. Dynamic calculations and measurements of ventilation by wind pressure fluctuation4. Air-tightening of the house and the concentrations of radon and radon-daughters5. Refreshing effects of fluctuating air current6. Whole house heating as the condition of air-tightening7. Improvement of exhausting range hoods in kitchen8. Actual conditions of ventilations in the attics and their use for a preheater of supply air to the living space9. Actual conditions of earth contacted spaces and countermeasures for dehumidification10. Efficiency of heat exchanging ventilation systems and their applications to the dehumidiffier11. Indoor climate of the house in eastern Hokkaido having cold and foggy days in summer

日本传统的木结构住宅适应了夏季潮湿的气候，全年过度通风。冬天只给房子的一部分供暖已成为根深蒂固的习俗，并一直延续到现在，房子的气密性正在迅速提高。在此背景下，八位研究人员进行了以下研究.实际房屋的气密性2.实际住宅室内温度、湿度和浓度的分布和波动<CO_2>3.风压脉动通风的动态计算与实测4.空气紧缩的房子和浓度的氡和氡子体5。波动气流的清新效果6.全屋供暖作为气密条件7.厨房抽油烟机的改进8.阁楼通风的实际条件及其作为生活空间空气预热器的用途9。接地空间的实际情况及除湿对策10.热交换通风系统的效率及其在除湿机上的应用11.室内气候的房子在东部北海道有寒冷和雾天在夏天
