The Energy Performance of Buildings Directive (EPBD) has introduced the concept of Nearly Zero Energy Buildings (NZEB) specifying that by 31 December 2020 all new buildings must meet the nearly zero- energy standard, the Passive House standard has emerged as a key enabler for the Nearly Zero Energy Building standard. The combination of Passive House with renewables represents a suitable solution to move to low/zero carbon. The hypothesis in this study is that a certified passive house building with high levels of airtightness with a balanced mechanical ventilation with heat recovery (MVHR) should yield lower indoor radon concentrations. This article presents results and analysis of measured radon levels in a total of 97 certified passive house dwellings using CR-39 alpha track diffusion radon gas detectors. The results support the hypothesis that certified passive house buildings present lower radon levels. A striking observation to emerge from the data shows a difference in radon distribution between upstairs and downstairs when compared against regular housing. The study is a first for Ireland and the United Kingdom and it has relevance to a much wider context with the significant growth of the passive house standard globally.
《建筑能源性能指令》（EPBD）引入了近零能耗建筑（NZEB）的概念，规定到 2020 年 12 月 31 日，所有新建筑都必须达到近零能耗标准，被动式房屋标准已成为实现近零能耗建筑标准的关键推动因素。被动式房屋与可再生能源的结合代表了向低碳/零碳迈进的合适解决方案。本研究的假设是，具有高气密性和平衡式机械通风与热回收（MVHR）的认证被动式房屋建筑应能降低室内氡浓度。本文介绍了使用 CR-39 阿尔法轨迹扩散氡气探测器对总共 97 座认证被动式房屋住宅进行的氡水平测量结果和分析。结果表明，认证被动式房屋建筑的氡水平较低，这一结果支持了假设。从数据中得出的一个显著观察结果是，与普通住房相比，楼上和楼下的氡分布存在差异。这项研究在爱尔兰和英国尚属首次，对于被动式房屋标准在全球范围内的显著增长，具有更广泛的意义。
