Exploring the solution to invert this tendency leads to several different scenarios of energy demand saving strategies that can be improved using phase change materials (PCM), especially in cold-formed steel-framed buildings. The present research reports the overheating (indoor air temperature above 26 \u00b0C expressed as an annualized percentage rate) reduction in south-oriented compartments and energy performance of a detached house located in the Aveiro region, in Portugal. An optimisation study was performed incorporating different phase change materials (PCMs) solutions and their position in the exterior envelope focusing overheating rate reduction and heating demand. The optimisations were managed by using a hybrid evolutionary algorithm coupled with EnergyPlus\u00ae simulation software. The overheating risk was reduced by up to 24% in the cooling season, for the case of the building compartments with south orientation. Thus, the use of construction solutions using PCMs with different melting temperatures revealed to be a good strategy to maximise PCM efficiency as a passive solution.<\/jats:p>","DOI":"10.3390\/app10228009","type":"journal-article","created":{"date-parts":[[2020,11,12]],"date-time":"2020-11-12T10:00:32Z","timestamp":1605175232000},"page":"8009","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Multiscale Modelling Approach Targeting Optimisation of PCM into Constructive Solutions for Overheating Mitigation in Buildings"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4324-7006","authenticated-orcid":false,"given":"Ant\u00f3nio","family":"Figueiredo","sequence":"first","affiliation":[{"name":"RISCO\u2014Department of Civil Engineering, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"Romeu","family":"Vicente","sequence":"additional","affiliation":[{"name":"RISCO\u2014Department of Civil Engineering, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8934-4907","authenticated-orcid":false,"given":"Rui","family":"Oliveira","sequence":"additional","affiliation":[{"name":"RISCO\u2014Department of Civil Engineering, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9127-7766","authenticated-orcid":false,"given":"Fernanda","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"RISCO\u2014Department of Civil Engineering, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"Ant\u00f3nio","family":"Samagaio","sequence":"additional","affiliation":[{"name":"Environment and Planning Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,12]]},"reference":[{"key":"ref_1","unstructured":"International Energy Agency (2018).
