“…Regarding daylight studies, similar results were found by the same authors, i.e., there is a clear tendency regarding the increase of glare tolerance as the day goes by [18]. More recent studies in daylight conditions have determined that people´s higher glare tolerance along the day can be attributed to the temporal effect of the source, a result which was found within certain conditions like those in which glare is not extreme [21]. This same result was confirmed by a controlled experiment with daylight carried out by Bian et al [22], which determined that people´s glare perception tolerance gradually increases during the morning until noon and becomes stable towards the afternoon.…”

Glare is considered one of the most important variables to reach visual comfort and visual quality. It represents one of the fundamental barriers for an effective use of daylighting in buildings. One of the best performing and robust glare prediction models, relative to other available metrics, is a Daylight Glare Probability (DGP). Based on a validated and precise methodology (RADIANCE) the aim of this work is to compare the DGP model (original cut-off values) with new cut-off values that differ according to the time of day (morning, noon and afternoon). Both cut-off values were compared at more than 300 simulated conditions of daylighting in an interior space. This work offers the originality of studying recently proposed cut-off values in climate luminous with predominant clear sky conditions. Currently, the application of these new cutoff values is reduced to the field of science or simulation professionals. The results showed important differences (64.86%) between the categories proposed by both cut-off values. Nevertheless, these differences do not have a significant impact in glare prediction (< 2.7%), in terms of glare absence (DGP <0.38) and presence (DGP >0.38). This analysis made it possible: (i) to regionally apply the main current corpus criteria regarding glare issues as well as emergent proposals and (ii) to present new experimental data aimed at helping the field and, together with other works, improving the tools used by professionals on a daily basis.

“…Debe existir un equilibrio de la luz natural ya que esta se refleja en las pantallas de las computadoras y produce deslumbramiento o reflejos inadecuados que pueden ser nocivos. Yamin et al, (2020), indican que, si el control solar es inadecuado, se tiende a bloquear la iluminación natural evitando el deslumbramiento y usando luz artificial, aumentando el consumo de energía; en los climas donde los cielos son claros, hay una gran disponibilidad de luz natural pudiendo ser aprovechada para el ahorro energético, sin embargo, es necesario un adecuado control solar lumínico y una adecuada correlación entre ellos.…”

En las instituciones, no solo se generan lazos laborales sino también del tipo social y afectivo que, aunado a las jornadas laborales extensas, hacen que de manera imperiosa se requiera de un ambiente laboral propicio, seguro y confortable. El objetivo de esta investigación es el de hacer un diagnóstico situacional basado en los docentes de la carrera de Ingeniería Civil de la Universidad Técnica de Manabí, mediante una investigación de campo, con enfoque cuantitativo y muestreo censal, para la aplicación de un cuestionario cuyos resultados fueron analizados bajo la técnica de semaforización; se determinaron dimensiones como clima organizacional referido a lo externo del trabajador y la motivación laboral referido a lo interno. Los resultados muestran que hay deficiencias asociadas al clima organizacional, pero que estas no influyen en la motivación de los trabajadores. Se concluye que los diagnósticos realizados a las organizaciones deben servir de insumos para la elaboración de planes de mejora que se centren en los aspectos desfavorables encontrados. Se recomienda que estos planes se constituyan en acciones inmediatas, a corto, mediano, y largo plazo según los resultados y que se mantengan incluso aquellos aspectos encontrados en estado óptimo.

Traditional architecture has characteristics of the place of origin that have been inherited from generation to generation and maintains an identity in each context. Today, this type of vernacular building is the object of study due to its value and the need for an unavoidable energy transition as a result of the depletion of fossil fuels. Thus, with the research, we seek to identify the worth of natural light in the inside space of traditional rural housing. To achieve this objective, the planimetric survey of the homes selected for the study was carried out, the performance of natural light in them was analyzed, and the optimization of natural light in the inside spaces of the houses was simulated. With the gotten results, it is highlighted that there are shortages of natural light in the inside spaces with a range of 3 to 280 lux, this is as a result of several factors, among them the size of the openings, the orientation, and the applied constructive system. Therefore, it is concluded that to improve the levels of luxes in the inside spaces of the house, changes are required at the constructive and materiality level, as well as the spatial and thermal level. In this way, it would be possible to guarantee the maintenance of this type of housing as a historical heritage.
