Daylight comfort and energy performance for non-residential building in extreme hot dry climate

The effects of daylight in interior spaces have a significant influence on the environment of the building, but even more, on the well-being of the user. The objective of this study was to analyze natural lighting and compliance with the range of 300 lux that NOM-025-STPS-2008 establishes as optimal...

description The effects of daylight in interior spaces have a significant influence on the environment of the building, but even more, on the well-being of the user. The objective of this study was to analyze natural lighting and compliance with the range of 300 lux that NOM-025-STPS-2008 establishes as optimal, the same as international standards consider as a minimum. An environmental and energy diagnosis was carried out using the Design Builder simulator, a private sector office located in an extreme dry hot climate was analyzed, five different sky scenarios were studied: one day with cloudy sky and four representative days with clear skies. The analysis to identify natural lighting was determined from the Daylight Factor expressed in lux. Lighting quality deficiencies or excesses were established from the results of the base case, in addition, another nine scenarios were simulated with different glazing systems to analyze the effects on heat gains. The properties of the material that allow a better thermal and light behavior are those with the lowest coefficient for solar heat gains and the highest coefficient for visible thermal light. The best glazing system is found with a double ultra-clear glass, by keeping the lighting only 5% lower than the base case and decreasing the heat gains per glazing by 18%. The best thermo-energetic condition was with a simple turquoise-blue tinted glass, since despite reducing the lighting by 25%, it allowed to comply with the Mexican standard and reduce heat gains by 55%. It is necessary to continue the study and modify the window-floor and window-wall ratio, as well as the shape and location of the opening to establish whether single tinted glass is better than double glazing systems.

Los efectos de iluminación natural en espacios interiores tienen una notable influencia sobre el ambiente de la edificación, pero más aún, en el bienestar del usuario. El objetivo de este estudio fue analizar la iluminación natural y el cumplimiento del rango de iluminación de 300 lux que la NOM-025-STPS-2008 establece como óptimo, mismo que estándares internacionales consideran como mínimo. Se realizó un diagnóstico ambiental y energético a partir del simulador Design Builder, se analizó una oficina del sector privado situada en clima cálido seco extremoso, así mismo, se estudiaron cinco escenarios de cielo distintos: un día de cielo nublado y cuatro días representativos de cielo claro. El análisis para identificar la iluminación natural se determinó a partir del Factor Luz Día expresado en lux. Se establecieron deficiencias o excesos de calidad de iluminación a partir de los resultados del caso base, además, se simularon otros nueve escenarios con diferentes sistemas de acristalamiento con el fin de analizar los efector sobre ganancias de calor. Las propiedades del material que permiten un mejor comportamiento térmico y lumínico son aquellos con menor coeficiente por ganancias de calor solar y mayor coeficiente visible térmico. El mejor sistema de acristalamiento se encuentra con un doble ultra claro, al mantener la iluminación solo 5% por debajo que el caso base y disminuir el 18% las ganancias de calor por acristalamiento. La mejor condición termo-energética fue con un vidrio sencillo tinte azul turquesa ya que a pesar de disminuir en 25% la iluminación, permitió cumplir con la norma mexicana y disminuir en 55% las ganancias de calor. Se requiere continuar el estudio y modificar la relación ventana-suelo y ventana-muro, así como la forma y ubicación del vano para establecer si realmente el vidrio sencillo tintado es mejor que los sistemas de acristalamiento doble.
