The present work presents a case study\u2019s experimental analysis composed of a BIPVT system for heat recovery located in a controlled test room. This work contribution focuses on the presentation of the obtained measured value results that correspond to the BIPVT main boundary conditions (weather and room characteristics) and the thermal behaviour and performance of the BIPVT system, located in the Solar XXI Building, a nZEB exposed to the mild Mediterranean climate conditions of Portugal.<\/jats:p>","DOI":"10.3390\/en14082191","type":"journal-article","created":{"date-parts":[[2021,4,14]],"date-time":"2021-04-14T15:30:39Z","timestamp":1618414239000},"page":"2191","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Performance Assessment of a Building-Integrated Photovoltaic Thermal System in a Mediterranean Climate\u2014An Experimental Analysis Approach"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5904-2166","authenticated-orcid":false,"given":"Karol","family":"Bot","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio Nacional de Energia e Geologia (LNEG), 1649-038 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9140-4953","authenticated-orcid":false,"given":"Laura","family":"Aelenei","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio Nacional de Energia e Geologia (LNEG), 1649-038 Lisbon, Portugal"}]},{"given":"H\u00e9lder","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio Nacional de Energia e Geologia (LNEG), 1649-038 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1499-1370","authenticated-orcid":false,"given":"Maria da Gl\u00f3ria","family":"Gomes","sequence":"additional","affiliation":[{"name":"CERIS, Department of Civil Engineering, Architecture and Georesources (DECivil), Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7532-3993","authenticated-orcid":false,"given":"Carlos Santos","family":"Silva","sequence":"additional","affiliation":[{"name":"IN+, Center for Innovation, Technology and Policy Research \/LARSyS, Department of Mechanical Engineering (DEM), Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisbon, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Edelenbosch, O.Y., Van Vuuren, D.P., Blok, K., Calvin, K., and Fujimori, S.
