For the return on investment (ROI), yields were translated into monetary value and compared with the initial investment, benchmarked against conventional aluminium or glass louvres.<\/p>\n<p>The simulations demonstrated that energy yield is strongly influenced by the position, geometry, and dimensions of the louvres.<\/p>\n<ul>\n<li><strong>Optimal positioning:<\/strong>\u00a0Side\u2011clamped glass proved to be the most advantageous solution, as it avoids structural shading of the PV cells and maximises energy yield.<\/li>\n<li><strong>Geometry:<\/strong> The large number of identical BIPV slats allows for custom manufacturing without excessive additional costs. Based on simulation results, the louvre dimensions were optimised to achieve maximum PV cell coverage, with the glass strip in the clamp intentionally left free of PV cells.<br \/>\nWind load calculations defined the required clamping profiles and glass thicknesses.<\/li>\n<\/ul>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t<\/div>\n<\/section>\n\n\n<section class=\"block cb block--white\" id=\"Inleiding\">\n\t<div class=\"block__inner cb__inner cb__inner--one\">\n\t<div class=\"col--12 col--center col--wrapper\">\n\t\t<div class=\"col col--6 editor-content\">\n\t\t\t<h2>Integration into the architectural and structural concept<\/h2>\n<p>The louvres serve a dual function: solar shading and energy generation through BIPV. As a highly visible architectural feature, they play a defining role in the building\u2019s fa\u00e7ade.<\/p>\n<p>Sweco\u2019s fa\u00e7ade engineering consultants ensured seamless integration into both the architectural and structural concepts through careful detailing and structural pre\u2011dimensioning of the glass and clamping profiles. The custom\u2011designed aluminium clamp profiles elegantly incorporate steel reinforcements and concealed electrical wiring, while specially designed anchors ensure that fixings and cable routing remain invisible.<\/p>\n<h2>Comfort through daylight optimisation<\/h2>\n<p>Once the fixed BIPV solar shading strategy was established, the fa\u00e7ade engineers assessed daylight comfort within the interior spaces. The louvres wrap around the entire building, creating a coherent and harmonious architectural expression.<\/p>\n<p>On the northern fa\u00e7ade, where PV yield is naturally lower, the louvres are fully transparent and do not contain PV cells, allowing additional daylight to enter the interior while maintaining visual consistency across the fa\u00e7ade.<\/p>\n<p>By involving fa\u00e7ade engineering from the earliest design stages, Sweco\u2019s experts were able to deliver solutions that significantly enhance energy performance while fully respecting the architectural intent.<\/p>\n<p>&nbsp;<\/p>\n<div class=\"buttons-wrapper buttons-wrapper--center\"><a href=\"https:\/\/www.swecobelgium.be\/en\/services\/facade-engineering\/\" target=\"\" class=\"btn btn__primary \">Discover our smart fa\u00e7ades solutions<\/a><\/div>\t\t<\/div>\n\t<\/div>\n<\/div>\n<\/section>\n\n\n<section class=\"block block--white latest-insights\" >\n\t<div class=\"block__inner latest-insights__inner\">\n\t\t<div class=\"col--11 col--wrapper\">\n\t\t\t\t\t\t\t<div class=\"col col--12 editor-content latest-insights__title\">\n\t\t\t\t\t<h2 class=\"h2 hyphenate\">Other news<\/h2>\t\t\t\t<\/div>\n\t\t\t\n\t\t\t\t\t\t\t\t<div class=\"col col--4 insight\" data-clickable=\"true\">\n\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"520\" height=\"296\" src=\"https:\/\/www.swecobelgium.be\/wp-content\/uploads\/sites\/12\/2025\/08\/gas-treatment-520x296.jpeg\" class=\"attachment-insights-featured size-insights-featured wp-post-image\" alt=\"\" \/>\t\t\t\t\t\t<div class=\"insight__content editor-content\">\n\t\t\t\t\t\t\t<em class=\"cats\">Expert Talk, Zero-Carbon, Industry Transition<span class=\"cats__sep\"><\/span>01\/04\/2026<\/em>\t\t\t\t\t\t\t<h3><a href=\"https:\/\/www.swecobelgium.be\/en\/news\/making-ccs-work-insights-from-real-industrial-projects\/\">Making CCS Work: Insights from Real Industrial Projects<\/a><\/h3>\n\t\t\t\t\t\t\t<p> <span class=\"readmore\">Read more<\/span><\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"col col--4 insight\" data-clickable=\"true\">\n\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"520\" height=\"296\" src=\"https:\/\/www.swecobelgium.be\/wp-content\/uploads\/sites\/12\/2026\/03\/2687_Stade-Hockey-Axono2_2025.07.09_LOGO-520x296.jpg\" class=\"attachment-insights-featured size-insights-featured wp-post-image\" alt=\"New national hockey stadium ready for the 2026 World Cup\" \/>\t\t\t\t\t\t<div class=\"insight__content editor-content\">\n\t\t\t\t\t\t\t<em class=\"cats\">Low-impact Buildings, Gebouwen met een lage impact<span class=\"cats__sep\"><\/span>30\/03\/2026<\/em>\t\t\t\t\t\t\t<h3><a href=\"https:\/\/www.swecobelgium.be\/en\/news\/new-national-hockey-stadium-ready-for-the-2026-world-cup\/\">New national hockey stadium ready for the 2026 World Cup<\/a><\/h3>\n\t\t\t\t\t\t\t<p> <span class=\"readmore\">Read more<\/span><\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"col col--4 insight\" data-clickable=\"true\">\n\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"520\" height=\"296\" src=\"https:\/\/www.swecobelgium.be\/wp-content\/uploads\/sites\/12\/2026\/03\/\u00a9TomDhaenens-UZ-Gent-2025-22-large-520x296.jpg\" class=\"attachment-insights-featured size-insights-featured wp-post-image\" alt=\"aerial image of the UZ Gent university hospital campus\" srcset=\"https:\/\/www.swecobelgium.be\/wp-content\/uploads\/sites\/12\/2026\/03\/\u00a9TomDhaenens-UZ-Gent-2025-22-large-520x296.jpg 520w, https:\/\/www.swecobelgium.be\/wp-content\/uploads\/sites\/12\/2026\/03\/\u00a9TomDhaenens-UZ-Gent-2025-22-large-200x113.jpg 200w\" sizes=\"auto, (max-width: 520px) 100vw, 520px\" \/>\t\t\t\t\t\t<div class=\"insight__content editor-content\">\n\t\t\t\t\t\t\t<em class=\"cats\">Sustainable Transport &amp; Mobility, Health &amp; Wellbeing, Low-impact Buildings, Zero-Carbon, Liveable Cities<span class=\"cats__sep\"><\/span>30\/03\/2026<\/em>\t\t\t\t\t\t\t<h3><a href=\"https:\/\/www.swecobelgium.be\/en\/news\/uz-gent-is-building-the-care-of-tomorrow-with-project-u\/\">UZ Gent is building the care of tomorrow with\u00a0Project U<\/a><\/h3>\n\t\t\t\t\t\t\t<p> <span class=\"readmore\">Read more<\/span><\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\n\t\t\t\t\t<\/div>\n\t<\/div>\n<\/section>\n\n<section class=\"block form-block block--lightgray\" >\n\t<div class=\"block__inner form-block__inner \">\n\n                    <div class=\"col--11 col--wrapper\">\n                                    <div class=\"col col--4 editor-content form-block__title\">\n                        <h2 class=\"h2 hyphenate\">Sign up for our newsletter<\/h2>                    <\/div>\n                    <div class=\"col--12 col\"><\/div>\n                \n                <div class=\"col col--4 editor-content\">\n                    Receive updates on groundbreaking projects, sustainable solutions, and exclusive insights from Sweco.
