These materials intelligently react to very low-voltage electrical stimuli &#8211; they can be activated with a simple 3-volt battery &#8211; changing the optical state and opacity of the glass within a few minutes. In addition to regulating temperature, the system is capable of optimising natural light and eliminating bothersome glare, improving the user&#8217;s visual comfort. The window is regulated through an intelligent control system that tints and clears the glass based on a predictive algorithm and real-time weather data.<\/p><p>The results of the tests carried out demonstrate a direct impact on sustainability and household and corporate economics: an <strong>annual reduction in energy consumption of more than 35%<\/strong> (including heating, cooling and lighting) is estimated, accompanied by <strong>an improvement in thermal and visual comfort<\/strong> under all climatic conditions and at every moment of the day and year.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-3d2a1d5 e-flex e-con-boxed e-con e-parent\" data-id=\"3d2a1d5\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-9a76019 e-con-full e-flex e-con e-child\" data-id=\"9a76019\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-95d7fb7 elementor-widget elementor-widget-image\" data-id=\"95d7fb7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"700\" height=\"700\" src=\"https:\/\/leitat.org\/wp-content\/uploads\/2026\/09\/Captura-de-pantalla-2026-09-04-111105--700x700.png\" class=\"attachment-tp-image-grid size-tp-image-grid wp-image-89220\" alt=\"\" srcset=\"https:\/\/leitat.org\/wp-content\/uploads\/2026\/09\/Captura-de-pantalla-2026-09-04-111105--700x700.png 700w, https:\/\/leitat.org\/wp-content\/uploads\/2026\/09\/Captura-de-pantalla-2026-09-04-111105--150x150.png 150w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-30e5190 e-con-full e-flex e-con e-child\" data-id=\"30e5190\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-b81d809 elementor-widget elementor-widget-image\" data-id=\"b81d809\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"700\" height=\"700\" src=\"https:\/\/leitat.org\/wp-content\/uploads\/2026\/09\/Leitat-finestra-intelligent-04--700x700.png\" class=\"attachment-tp-image-grid size-tp-image-grid wp-image-89226\" alt=\"\" srcset=\"https:\/\/leitat.org\/wp-content\/uploads\/2026\/09\/Leitat-finestra-intelligent-04--700x700.png 700w, https:\/\/leitat.org\/wp-content\/uploads\/2026\/09\/Leitat-finestra-intelligent-04--150x150.png 150w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-2e2c9b6 e-flex e-con-boxed e-con e-parent\" data-id=\"2e2c9b6\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-2c0d69b elementor-widget elementor-widget-text-editor\" data-id=\"2c0d69b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h4>Boost and collaboration in R&amp;D&amp;I<\/h4><p>This technological milestone has been consolidated thanks to the boost provided by strategic research projects such as Smartlux, led by the technology centre itself with the aim of bringing the latest-generation nanomaterials towards real market applications.
