In this study, we present an analysis of a classroom simulated in Dialux, involving a comprehensive examination of natural daylight through a specific type of glazing, assessing their photopic characteristics and their influence on the human circadian system in individuals aged 32 and 70 years. Our findings highlight that spectral data from daylight (D75, D65, and D50) and glazing transmittance can be easily used to evaluate the melanopic equivalent daylight illuminance (mel-EDI) in addition to standard photopic illuminance, applying a f(MP)Glazing factor calculated from the spectral characteristics of both daylight and glazing transmittance. Our results provide new insights for users to more effectively assess daylighting quality and its implications within indoor environments. info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 3.1 2024 ENGINEERING, CIVIL 60 / 184 = 0.326 2024 Q2 T1 CONSTRUCTION & BUILDING TECHNOLOGY 31 / 95 = 0.326 2024 Q2 T1 0.652 2024 Architecture 2024 Q1 Civil and Structural Engineering 2024 Q2 Building and Construction 2024 Q2 4.4 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Orduna-Hospital, Elvira Universidad de Zaragoza (orcid)0000-0003-2710-1875 Aporta, Justiniano Universidad de Zaragoza (orcid)0000-0003-2968-228X 2002 647 Universidad de Zaragoza Dpto.
