The quality of a lit environment cannot be deduced solely from the quantity of light. Therefore, daylighting studies should not only be focused on the usage of lighting metrics but should also consider the aesthetic experience. This paper examines the influence of daylighting systems on the aesthetic perception of a small office. One single side lit office was equipped with four different daylighting systems (white blinds, high-reflecting blinds, hybrid light shelf and mirror light shelf) under two sky conditions (clear sky and overcast sky). In total, eight stimuli were captured and presented via stereoscopic images. Fifty participants evaluated the images using the semantic differential scale to rate nine architectural quality attributes. The results from MANOVA indicated that both the daylighting systems and the type of sky had an effect on the aesthetic attributes, and that the significant interaction effect suggested that the aesthetic perception of a daylighting system depends on the type of sky. Subsequent statistical findings showed that the high-reflecting blinds comprised the daylighting system that scored highest in nearly all attributes under both clear and overcast sky conditions.

Abstract For many generations, works of art have been a source for experiencing beauty. They add to the wealth of our culture because they convey universal themes and values. In this study, we treat paintings as a stimulus for personal story-telling. The purpose was to explore the affective quality of personal meanings present in autobiographical narratives. Our findings show that subjective ratings of the beauty of figurative paintings are linked with the quality and theme of personal experiences recalled in response to viewing them, but not related to the length of the story. ‘Beautiful’ pictures elicit descriptions of desirable experiences associated with passive contemplation and satisfied self-enhancement motive. ‘Non-beautiful’ pictures call to mind difficult experiences linked with frustration. The experts formulated longer self-narratives inspired by paintings rated beautiful in comparison to laypersons, and laypersons formulated longer self-narratives inspired by paintings rated not beautiful in comparison to experts. The results are discussed in connection to the nature of the aesthetic experience and specificity of personal maenings.

Purpose This study aims to provide a holistic understanding of how visual storytelling influences the objective and subjective cognitive responses of consumers, namely objective aesthetic impression and subjective aesthetic association, and aesthetic judgments in response to differing levels of novelty in design innovations. Design/methodology/approach A mixed-factorial experimental study manipulating the novelty of chair designs (moderate/high) and visual design stories (present/absent) was conducted among 263 female US consumers to test the proposed research model. Findings With respect to the main effects of novelty and visual design stories, consumers had more positive cognitive responses and aesthetic judgments to: product designs with moderate (vs high) novelty; and products with visual design stories than without. A significant interaction effect uncovered that visual design stories particularly aided products with high (vs moderate) design novelty with respect to objective aesthetic impressions. Examination of the structural relationships between the variables revealed that subjective aesthetic associations mediate the relationship between objective aesthetic impressions and aesthetic judgments. Practical implications To mitigate risk in radical design innovations, marketers should use visual storytelling to communicate product form associations and enable consumers to successfully decode the meaning of novel designs during initial encounters. Originality/value By examining a holistic model involving both perceptual and conceptual product concepts, this study fills a critical research void to develop insightful implications on bridging the gap between novel product designs and consumer understanding.

Daylighting levels in interiors are changed every day since sunrise to sunset in dependence on luminous exterior conditions. Indoors are illuminated by diffuse skylight prevailing time of the year in Central European counties while a lot of sunny situations occur mainly during transitional and summer periods. The later can produce overheating as well as glare or disturbing luminance due to excessive sunlight in the space close to windows. If interiors are designed with screened work places the influence of direct sunlight during working time has to be evaluated.The article will present results of computer daylight simulations in a side-lit office room oriented to cardinal points. The study is focused on daylighting evaluation of the room orientation influence on levels under clear sky conditions and compared with results achieved for the CIE overcast sky model. The calculations were run in software Daylight Visualizer 2.6.7. The daylight simulation show that applying the clear sky model for illumination of oriented rooms, the substantial different illuminances can be resulted compared to outputs from the common overcast sky daylight metrics.

A flexible mathematical model is introduced which describes the radiance of the dome of the sky under various conditions. This three-component continuous distribution (TCCD) model is compounded by the superposition of three separate terms, isotropic, circumsolar and horizon-brightening factors, each representing the contribution of a distinguishable sky characteristic. In use, a particular sky condition is characterized by the values of the coefficients of each of these three terms, defining the distribution of the total diffuse component. The TCCD model has been demonstrated to fit both the normalized clear sky data and the normalized overcast sky data with an RMS error of about ten percent of the mean overall sky radiance. By extension the model could describe variable or partly clouded sky conditions. The model will permit improvement in the prediction of the total solar radiation incident upon a surface of given tilt and orientation, such as that of a solar collector.

Abstract. A new fast clear-sky model called McClear was developed to estimate the downwelling shortwave direct and global irradiances received at ground level under clear skies. It is a fully physical model replacing empirical relations or simpler models used before. It exploits the recent results on aerosol properties, and total column content in water vapour and ozone produced by the MACC project (Monitoring Atmosphere Composition and Climate). It accurately reproduces the irradiance computed by the libRadtran reference radiative transfer model with a computational speed approximately 105 times greater by adopting the abaci, or look-up table, approach combined with interpolation functions. It is therefore suited for geostationary satellite retrievals or numerical weather prediction schemes with many pixels or grid points, respectively. McClear irradiances were compared to 1 min measurements made in clear-sky conditions at several stations within the Baseline Surface Radiation Network in various climates. The bias for global irradiance comprises between −6 and 25 W m−2. The RMSE ranges from 20 W m−2 (3% of the mean observed irradiance) to 36 W m−2 (5%) and the correlation coefficient ranges between 0.95 and 0.99. The bias for the direct irradiance comprises between −48 and +33 W m−2. The root mean square error (RMSE) ranges from 33 W m−2 (5%) to 64 W m−2 (10%). The correlation coefficient ranges between 0.84 and 0.98. This work demonstrates the quality of the McClear model combined with MACC products, and indirectly the quality of the aerosol properties modelled by the MACC reanalysis.

Abstract This work describes the development of a simple method of field estimating the sky cloud coverage percentage for several applications at the Brazilian Antarctic Station, Ferraz (62°05′S, 58°23.5′W). The database of this method was acquired by a digital color camera in the visible range of the spectrum. A new algorithm was developed to classify each pixel according to a criteria decision process. The information on the pixel contamination by clouds was obtained from the saturation component of the intensity, hue, and saturation space (IHS). For simplicity, the images were acquired with a limited field of view of 36° pointing to the camera’s zenith to prevent direct sunlight from reaching the internal charge-coupled device (CCD) on the camera. For a priori–classified clear-sky images, the accuracy of the method was superior to 94%. For overcast-sky conditions, the corresponding accuracy was larger than 99%. A comparison test was performed with two human observers and our method. The results for the 29 images collected for several time of days during 50 days in 1999 summer were compared to visual observations of these same digital images by two trained field meteorologists. Correlation coefficients between human observers and the automatic method ranged from 0.84 for clear-sky conditions, and the lowest was 0.09 for undefined-sky conditions.

AbstractThe evaluation of daylight conditions in building interiors is based on the Daylight Factor concept after current Slovak standards. Criteria and requirements determined in these standards consider the worst daylight exterior conditions which are described by CIE overcast sky model. The sky luminance distribution of overcast sky is centrical to the zenith, so independence of window orientation to cardinal points is characteristic in daylighting calculations. The sky luminance distribution modelling is one of the main task of the daylight source research more than 50 years. It is evident that also other types of sky conditions exist in nature. An introduction of a new criterion based on photometric variables, which also consider sunlight influence, is expected. This article represents a study of the influence of the interior orientation on distribution of daylighting in attic spaces under an overcast and clear sky

Introduction. Natural illumination calculations depend on the sky luminance distribution. The most often used diagram of sky luminance in handbooks and guidelines is the luminance distribution in the cloudy sky proposed by Moon and Spencer. This concept actually includes the tropical areas of Vietnam, where the overcast sky and clear sky does not typically occur. To improve the calculation of natural illumination, it is necessary to determine the luminance distribution in the real sky. Materials and methods. In solving the research problem, the real sky types for Hanoi were identified using the 15 international standard sky types with their descriptions by lighting climate, which is provided using the method by R. Kittler. The descriptions are derived from the data on diffuse horizontal illumination Dv, extraterrestrial horizontal illumination Ev and light turbidity coefficient Tv. For a specific sky type, the standard parameters were selected for calculating the luminance distribution of the real sky. Results. The obtained results show that the typical sky type of Hanoi is the partly cloudy sky, no gradation towards zenith, with slight bleaching towards the Sun (type VI). The sky types from October to December are partly cloudy with the obscured Sun (type IX) and partly cloudy with the more luminant circumsolar area (type X). The study shows that the state of cloud coverage has a great influence on the level of diffuse horizontal illumination and luminance distribution under tropical sky conditions. Conclusions. It is revealed that the typical sky type for Hanoi is neither overcast nor clear sky. A typical sky with statistic dominance of cirrus and stratus clouds under effect of high solar radiation of Vietnamese tropical climate gives a high level of diffuse horizontal illuminance. The results show that the difference in luminance distribution between the CIE standard overcast sky and Kittler’s intermediate sky can be resolved at the angles of sky point elevation above horizon γ is higher than 50° with the relative errors below 10 %. In other words, the luminance distribution β of the considered sky type is significant for a system of side natural illumination.

La estética fenomenológica debería ser capaz de revelar cómo la estructura de cualquier objeto estético dado está conectada con la experiencia de ese objeto, así como demostrar las condiciones necesarias para la propia experiencia estética. Para hacerlo, hay que argumentar en contra de los supuestos unilaterales, como por ejemplo la suposición del objetivismo estético que postula la belleza como rasgo exclusivo de la realidad independiente del sujeto; o la creencia opuesta, que la belleza es esencial y únicamente la proyección del gusto subjetivo sobre las cosas en el mundo. Sesemann analiza el objeto estético y el acto estético, enfatizando su conexión. Esta conexión se refiere a lo que se describe en la fenomenología de Husserl como la correlación entre el objeto intencional y el acto intencional. Esta conexión puede ser descubierta sólo mediante el método fenomenológico: realizando la reducción fenomenológica. En este documento se explicará en primer lugar la percepción estética en la estética de Sesemann. Más adelante, se examina la concepción de la estructura del objeto estético en el contexto de la estética de Sesemann: la composición de los elementos, las sensaciones en relación con el significado, etc. Por último, el artículo sugiere que la estética de Sesemann se basa fundamentalmente en el método de la reducción fenomenológica.Phenomenological aesthetics should also be able to show how the structure of any given aesthetic object is connected with the experience of that object, as well as to demonstrate the necessary conditions for the aesthetic experience itself. In order to do so, one must argue against one-sided assumptions, such as the aesthetic objectivism’s supposition that beauty is exclusively the trait of reality not at all dependent on the subject’s experience of it; or its opposite belief that beauty is essentially and solely the projection of the subjective taste onto the things in the world. Sesemann analizes the aesthetic object and aesthetic act by emphasizing their connection. This connection relates to what is described in Husserls phenomenology as the correlation between the intentional object and the intentional act. This connection can be discovered only by using the phenomenological method: by doing phenomenological reduction. This paper will first explain the aesthetic perception in Sesemann‘s aesthetics. Later, it examine the conception of the aesthetic object‘s structure in Sesemann‘s aesthetic: composition of elements, sensations in connection with meaning; etc. Finally, the paper will argue that Sesemann‘s aesthetics is essentially based on the method of phenomenological reduction.

The article observes the new approach to a lighting environment in premises of civil buildings in hot and sunny climatic conditions. Under such conditions, the use of sun-protective devices (SPD) of different types and geometrics becomes traditional way of passive climate control in interiors. However, the authors determined, that the most traditional types of external SPD (such as canopies or awnings) have a different effect on indoor lighting environment due to the conditions of external natural illumination under overcast sky vault or clear sky conditions. In the first case, the stationary SPD act as shadowing elements, which block the light flows from the CIE standard overcast sky. In the second case, which corresponds to a clear sky sunny conditions, such SPD block the solar radiation, decreasing overheating and reflect sun beams to an interior, increasing the value of daylight factor (DF) at least in the furthest from windows areas of a premise. The proposed solutions allow reducing electric power consumption in buildings.
