1.A new measuring method for evaluating ventilation rate was developed.2.Ventilation rates and indoor air quality in airtight houses in most parts of Japan were investigated by field measurements. Field measurements were carried out in summer and winter for three years.・The result of measurement of airflow at outlet shows that 19 (68%) houses out of 28 indicate a low air change rate, which is lower than 0.5 h^<-1>.・The result of ventilation airflow rate by constant concentration method shows that 9 (43%) houses out of 21 indicate a low air change rate, which is lower than 0.5h^<-1>.・The formaldehyde concentrations in 39 (40%) rooms of 98 exceeded the criterion of the guideline from the Ministry of Health, Labor and Welfare of Japan.・TVOC concentrations in 52 (53%) rooms of 99 exceeded the criterion of the advisable value from the Ministry of Health, Labor and Welfare of Japan.・In the residence where the amount of ventilation rates was insufficient, chemistry substance concentrations exceeded the criterion of the guideline in many cases.3.Numerical of thermal and ventilation performance on airtight houses sere carried out. The accuracy of numerical analysis was checked by comparing numerical simulations and results of field measurement.4.Solutions to problems in those houses were suggested by numerical simulations.

1.提出了一种新的评价通风量的测量方法。2.对日本大部分地区密闭住宅的通风量和室内空气品质进行了现场测量。在夏季和冬季进行了为期三年的实地测量。·排风量的测量结果表明，28户住宅中有19户（68%）的换气次数低于0.5h ↑ [<-1>2]。用定浓度法测定通风风量的结果表明，21户住宅中有9户（43%）的换气次数低于0.5h ↑ [<-1>2]。98间客房中有39间（40%）的甲醛浓度超过日本厚生劳动省的标准。·在99个房间中，有52个房间（53%）的TVOC浓度超过了日本厚生劳动省的建议值标准。·在通风量不足的住宅中，化学物质的浓度在很多情况下超过了指南的标准。3.对密闭住宅的热工性能和通风性能进行了数值计算。通过数值模拟与现场实测结果的对比，验证了数值分析的准确性。4.通过数值模拟，提出了解决该类房屋存在问题的建议。
