“…As Simmler, H. (2008) noted, studies carried out have shown that energy demand by overheating has become a recurring problem in fully glazed facades due to excessive solar gains [4][5][6]. In Chile, a study conducted by Bodart et al (2010) in districts of Santiago, showed that the predominant typology of the office building is the fully glazed façade with selective double glazing (68% of the sample analysed), and presents severe problems in terms of thermal and visual comfort caused by overheating and glare [7]. Other studies determined the same results due to overexposure of the indoors to direct sunlight [8].…”

It has been shown that in buildings with fully glazed facades designed to save electricity and increase daylight, overheating due to excessive solar gains and glare have become recurrent problems, affecting the quality of the indoor environment in office buildings. Likewise, the focus should not only be on reducing energy consumption but also on providing comfort by applying daylight strategies appropriate to each context. In contexts such as Chile, where there is significant variability of daylight due to the extension of the territory, (17°29'57" S -56°32'12" S) designing with the correct passive solar strategies can become a challenge. The main purpose of this study is to investigate the application of passive solar strategies in side-lit office spaces, focusing on designs that maximise daylight penetration while protecting occupants from the risks of direct solar glare, and on methods to predict the daylight performance. A theoretical model is the prototype of an experimental office, located in three Chilean cities with different prevailing sky conditions, but adapted to the different contexts by integrating the design strategies recommended by the leading entities in advanced energy and daylight design. Daylight performance was evaluated using climate-based daylight modelling, with spatial daylight autonomy, annual sunlight exposure, and useful daylight illuminance metrics, which can integrate the daylight provision and potential glare prediction into a combined approach. This analysis was complemented by using a daylight glare probability index to verify the upper-lit thresholds of the applied methods. This paper provides an easy-to-apply daylight strategies guide for designers and the comparison of the daylight metrics in different climate contexts.

“…Se pueden distinguir desde las ventanas tradicionales que simplemente son una barrera que permite ver el exterior, hasta una gran variedad de alto desempeño como ventanas con flujo de aire, sombras externas, o bien doble piel. Asimismo, existe también una tendencia a diseñar edificios con grandes ventanales que habitualmente presentan serios problemas de sobrecalentamiento y deslumbramiento en sus espacios interiores (Bodart, 2010), sin considerar los efectos de las radiaciones de las diferentes longitudes de onda que son capaces de penetrarlos.…”

“…Por este motivo, uno de los factores que comúnmente se utilizan en el diseño de edificios es el factor de Luz Diurna desarrollado en Reino Unido (Bodart, 2010). No obstante, este factor solamente contempla la relación entre la iluminancia horizontal en un punto dentro del edificio y uno exterior, pero no existe algún indicador acerca de la luz ultravioleta que es capaz de penetrar el cristal (Acosta, 2016).…”

“…The energy efficiency must be evaluated while accounting for the thermal environment [7]. Some studies carried out have shown that energy demanded by overheating has become a recurring problem due to excessive solar gains [8][9][10][11] and glare and direct solar gains affect the thermal and visual comfort [3,11,12] in fully glazed facades. Performative façade design can improve the thermal and visual and comfort conditions [13] while reducing energy consumption as the building's skin have an important role in controlling the solar radiation.…”

With the use of Perforated Solar Screen (PSS), solar gains are controlled, cooling loads are reduced, and comfort conditions can be achieved while using its energy efficiently. Nowadays, the use of PSS is increased, especially in large, glazed facades. The design of PSS needs to develop and optimize for the temperate humid climate. A new design proposal is presented by considering the basic principles in terms of providing solar control by PSS within the scope of the study. The optimization of the design proposal has been carried out in terms of solar radiation, Annual Sun Exposure (ASE), and View with the use of Rhinoceros/Grasshopper by considering the design variables (angle, perforation ratio, width, and distance, etc.) of the PSS. An optimum design proposal has been presented for the existing classroom (transparency ratio: 60%) on the southern facade. Thermal comfort and surface temperature have been calculated. Design proposals can be developed for the west and east facades by using the method of this study.
