The heat exchange occurs through transparent surfaces and radiation reaches the building as light and heat. Therefore, glazings significantly contribute to the heat transfer between outdoor and indoor spaces and act directly on daylighting and thermal comfort. This paper reports on the spectrophotometric characterization of glazings transmittance for the study of components of a modular fa\u00e7ade system and its suitability for the climate of Portugal (temperate climate). The study focused on results of spectrophotometric measurements of optical properties, specifically the transmittance of some types of glazings (solar control, self-cleaning, low-e, float, and extra-clear) and two types of double glazings. The results show the percentage of transmission to ultraviolet, visible, and near-infrared regions and its importance, which enabled the analysis of the glazing efficiency regarding daylighting and the correlation to thermal performance. Subsidies and indications for the specification and adequate uses of transparent surfaces have been presented and complemented the datasheets available from the manufactures.<\/jats:p>","DOI":"10.3390\/su13105437","type":"journal-article","created":{"date-parts":[[2021,5,14]],"date-time":"2021-05-14T03:28:36Z","timestamp":1620962916000},"page":"5437","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Specification of Glazings for Fa\u00e7ades Based on Spectrophotometric Characterization of Transmittance"],"prefix":"10.3390","volume":"13","author":[{"given":"Helenice Maria","family":"Sacht","sequence":"first","affiliation":[{"name":"Latin American Institute of Technology, Infrastructure and Territory (ILATIT), Federal University for Latin American Integration (UNILA), Foz do Igua\u00e7u, PR 85867-970, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4246-8157","authenticated-orcid":false,"given":"Lu\u00eds","family":"Bragan\u00e7a","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, University of Minho, 4800-533 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2713-6322","authenticated-orcid":false,"given":"Manuela","family":"Almeida","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, University of Minho, 4800-533 Guimar\u00e3es, Portugal"}]},{"given":"Rosana","family":"Caram","sequence":"additional","affiliation":[{"name":"Institute of Architecture and Urbanism (IAU), University of S\u00e3o Paulo (USP), S\u00e3o Carlos, SP 13566-590, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"94","DOI":"10.1177\/1420326X09358020","article-title":"UV-Ray Filtering Capability of Transparent Glazing Materials for Built Environments","volume":"19","author":"Kim","year":"2010","journal-title":"Indoor Built Environ."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"302","DOI":"10.1016\/j.enbuild.2014.11.019","article-title":"Spectral and angular solar properties of a PCM-filled double glazing unit","volume":"87","author":"Goia","year":"2015","journal-title":"Energy Build."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1016\/j.enbuild.2013.11.045","article-title":"Polycarbonate panels for buildings: Experimental investigation of thermal and optical performance","volume":"70","author":"Morettia","year":"2014","journal-title":"Energy Build."},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"1107","DOI":"10.1016\/j.buildenv.2008.08.005","article-title":"Double skin fa\u00e7ades for warm climate regions: Analysis of a solution with an integrated movable shading system","volume":"44","author":"Baldinelli","year":"2009","journal-title":"Build.
