The present work analyzed melanopic light in four teaching environments considering photopic indoor lighting, daylight depending on the window orientation, location of the observer in the room, and their line of view. The façade direction, daylight at 11.00 a.m. for six months from October to March, and the characteristics of each classroom, such as reflectance of the surfaces, location of the luminaires and their spectral and spatial power distributions, or calculation points affecting the melanopic light reaching the corneal vertical plane of a hypothetical control observer were studied. For this evaluation, classrooms were experimentally treated and simulated using DialuxEvo software, and the computer-generated values resembled the experimental values. Once the study was performed, an improvement proposal, based on LED lighting, was made to optimize the classroom lighting considering the melanopic requirements, which we ensured that users who passed through these classrooms had an adequate amount light at any time of the day. Our results simplify to the greatest lighting projects and enable designers to carry out optimized evaluations of specific environments from both the photometric and circadian perspectives. 000109093 536__ $$9info:eu-repo/grantAgreement/ES/DGA/B08-20R$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/PID2019-107058RB-I00 000109093 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000109093 590__ $$a3.324$$b2021 000109093 594__ $$a3.8$$b2021 000109093 591__ $$aENGINEERING, CIVIL$$b58 / 139 = 0.417$$c2021$$dQ2$$eT2 000109093 591__ $$aCONSTRUCTION & BUILDING TECHNOLOGY$$b28 / 68 = 0.412$$c2021$$dQ2$$eT2 000109093 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000109093 700__ $$0(orcid)0000-0003-2710-1875$$aOrduna-Hospital, Elvira$$uUniversidad de Zaragoza 000109093 700__ $$aSolana, Teresa 000109093 700__ $$0(orcid)0000-0003-2968-228X$$aAporta, Justiniano$$uUniversidad de Zaragoza 000109093 700__ $$0(orcid)0000-0003-0349-9997$$aPinilla, Isabel$$uUniversidad de Zaragoza 000109093 700__ $$0(orcid)0000-0002-5621-1937$$aSánchez-Cano, Ana$$uUniversidad de Zaragoza 000109093 7102_ $$11013$$2646$$aUniversidad de Zaragoza$$bDpto.
