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-393 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.<\/jats:p>","DOI":"10.3390\/ijerph17114149","type":"journal-article","created":{"date-parts":[[2020,6,12]],"date-time":"2020-06-12T05:02:24Z","timestamp":1591938144000},"page":"4149","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["An Investigation into Indoor Radon Concentrations in Certified Passive House Homes"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1083-3466","authenticated-orcid":false,"given":"Barry","family":"Mc Carron","sequence":"first","affiliation":[{"name":"School of Natural and Built Environment, Faculty of Built Environment, Creative and Life Sciences, South West College, Enniskillen BT74 4EJ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianhai","family":"Meng","sequence":"additional","affiliation":[{"name":"School of Natural and Build Environment, Faculty of Engineering and Physical Sciences, Queens University Belfast, Belfast BT7 1NN, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shane","family":"Colclough","sequence":"additional","affiliation":[{"name":"School of Architecture, Planning and Environmental Policy, Faculty of Engineering and Architecture, University College Dublin, D04 V1W8 Dublin, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,10]]},"reference":[{"key":"ref_1","unstructured":"BBC News (2020, June 09).
