Three seasons were compared at two different times and two orientations (North and South) where only one window was placed. We used Radiance and Autodesk Ecotec software. Our results showed that during winter and facing South the average lighting levels exceed 27 times the values established by the Official Mexican Norm (NOM-025-STPS-1999 Lighting conditions in work spaces) in winter at South orientation at 12:00 hrs. It was also proven that color reflection coefficient plays an essential role in lighting, increasing up to 63% the level of illuminationKeywords: Natural lighting, simulation, orientation, season, color. Este artículo se centró en el desarrollo de 36 simulaciones virtuales de iluminación natural, con el objetivo de proporcionar una visión de los aportes de la simulación de luz natural en un espacio de oficina y describir sus resultados según las normas para la eficiencia visual, considerando variaciones estacionales, de hora, de orientación y de color a través de la utilización de software especializado. Se compararon tres estaciones del año, en dos horarios distintos y dos orientaciones (Norte y Sur) en donde se colocó una única ventana. El software utilizado fue Radiance y Autodesk Ecotect, los resultados mostraron que los niveles de iluminación promedio llegan a superar hasta por 27 veces los valores establecidos por Norma Oficial Mexicana (NOM-025-STPS-1999 condiciones de iluminación en los centros de trabajo) en la orientación Sur en época de invierno a las 12:00 hrs. También se demostró que el coeficiente de reflexión del color juega un papel imprescindible, aumentando hasta en un 63% el nivel de iluminación.Palabras clave: iluminación natural, simulación, orientación, estación del año, color.
