In this paper, the importance of monitoring new building concepts is discussed. The effect of energy-efficient construction technologies on indoor radon is presented in more detail. Comparing the radon levels of about 100 low-energy and passive houses in Austria with radon levels in conventional new houses show that, in energy-efficient new houses, the radon level is about one-third lower than in conventional new houses. Nevertheless, certain features or bad practice may cause high radon levels in energy-efficient new houses. Recommendations to avoid adverse effects were set up. Furthermore, the paper deals with the effect of thermal retrofitting on indoor radon. Results from a Swiss study where 163 dwellings were measured before and after thermal retrofit yield an increase of the radon level of 26% in average. Among the various retrofit measures, replacing windows has the greatest impact on the indoor radon level.
本文讨论了监测新建筑概念的重要性。更详细地介绍了节能建筑技术对室内氡的影响。将奥地利约100栋低能耗和被动式房屋的氡水平与传统新建房屋的氡水平进行比较，结果表明，在节能新建房屋中，氡水平比传统新建房屋低约三分之一。然而，某些特征或不良做法可能导致节能新建房屋中的氡水平升高。文中给出了避免不良影响的建议。此外，本文还探讨了热力改造对室内氡的影响。瑞士一项对163处住宅进行热力改造前后测量的研究结果显示，氡水平平均升高了26%。在各种改造措施中，更换窗户对室内氡水平的影响最大。
