However, the high thermal conductivity of steel presents a drawback, which may lead to thermal bridges if not well designed and executed. Furthermore, given the high number of steel profiles and its reduced thickness, it is not an easy task to accurately predict its thermal performance in laboratory and even less in situ. In a previous article, the authors studied the importance of flaking heat loss in lightweight steel-framed walls. This article discusses several thermal bridges mitigation strategies to improve a lightweight steel-framed wall model, which increase its thermal performance and reduce the energy consumption. The implementation of those mitigation strategies leads to a reduction of 8.3% in the U-value, comparatively to the reference case. An optimization of the wall module insulation layers is also performed (e.g. making use of new insulation materials: aerogel and vacuum insulation panels), which combined with the mitigation approaches allows a decrease of 68% in the U-value, also relatively to the reference case. Some design rules for lightweight steel-framed elements are also presented.<\/jats:p>","DOI":"10.1177\/1744259115572130","type":"journal-article","created":{"date-parts":[[2015,2,26]],"date-time":"2015-02-26T02:08:06Z","timestamp":1424916486000},"page":"342-372","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":57,"title":["Lightweight steel-framed thermal bridges mitigation strategies: A parametric study"],"prefix":"10.1177","volume":"39","author":[{"given":"Cl\u00e1udio","family":"Martins","sequence":"first","affiliation":[{"name":"ISISE, Department of Civil Engineering, Faculty of Science and Technology, University of Coimbra, Coimbra, Portugal"}]},{"given":"Paulo","family":"Santos","sequence":"additional","affiliation":[{"name":"ISISE, Department of Civil Engineering, Faculty of Science and Technology, University of Coimbra, Coimbra, Portugal"}]},{"given":"Lu\u00eds Sim\u00f5es","family":"da Silva","sequence":"additional","affiliation":[{"name":"ISISE, Department of Civil Engineering, Faculty of Science and Technology, University of Coimbra, Coimbra, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2015,2,20]]},"reference":[{"key":"bibr1-1744259115572130","doi-asserted-by":"publisher","DOI":"10.1016\/j.apenergy.2011.04.040"},{"key":"bibr2-1744259115572130","doi-asserted-by":"publisher","DOI":"10.1016\/j.enbuild.2010.12.012"},{"key":"bibr3-1744259115572130","doi-asserted-by":"publisher","DOI":"10.1016\/j.enbuild.2009.09.005"},{"key":"bibr4-1744259115572130","first-page":"621","volume-title":"Conference proceedings by ASHRAE","author":"Blomberg TR","year":"1998"},{"key":"bibr5-1744259115572130","unstructured":"EN ISO 10211:2007 (2007) Thermal bridges in building construction \u2013 heat flows and surface temperatures \u2013 detailed calculations, European Committee for Standardization."},{"key":"bibr6-1744259115572130","unstructured":"EN ISO 6946:2007 (2007) Building components and building elements \u2013 thermal resistance and thermal transmittance \u2013 calculation method, European Committee for Standardization."},{"key":"bibr7-1744259115572130","volume-title":"ASIEPI \u2013 Impact of Thermal Bridges on the Energy Performance of Buildings","author":"Erhorn-Klutting H","year":"2009"},{"key":"bibr8-1744259115572130","doi-asserted-by":"publisher","DOI":"10.1016\/S0263-8231(98)00028-7"},{"key":"bibr9-1744259115572130","volume-title":"OPTIM-R External Wall System \u2013 Next Generation Insulation Solution for External Masonry Walls","author":"Kingspan UK","year":"2013"},{"key":"bibr10-1744259115572130","doi-asserted-by":"publisher","DOI":"10.1016\/0378-7788(94)00913-5"},{"key":"bibr11-1744259115572130","doi-asserted-by":"publisher","DOI":"10.1016\/j.tws.2008.01.029"},{"key":"bibr12-1744259115572130","doi-asserted-by":"publisher","DOI":"10.1177\/1744259113499212"},{"key":"bibr13-1744259115572130","series-title":"Technical Committee 14-Sustainability & Eco-Efficiency of Steel Construction","volume-title":"Energy efficiency of light-weight steel-framed Buildings","volume":"129","author":"Santos P","year":"2012","edition":"1"},{"key":"bibr14-1744259115572130","doi-asserted-by":"publisher","DOI":"10.1177\/1744259111403440"},{"key":"bibr15-1744259115572130","doi-asserted-by":"publisher","DOI":"10.1016\/j.tws.2007.01.006"}],"container-title":["Journal of Building Physics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1744259115572130","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1744259115572130","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1744259115572130","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T21:22:29Z","timestamp":1777497749000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1744259115572130"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,2,20]]},"references-count":15,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2016,1]]}},"alternative-id":["10.1177\/1744259115572130"],"URL":"https:\/\/doi.org\/10.1177\/1744259115572130","relation":{},"ISSN":["1744-2591","1744-2583"],"issn-type":[{"value":"1744-2591","type":"print"},{"value":"1744-2583","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,2,20]]}}}
