“…This scale model has been set with reference to a common small office form in Korea. The center of the space is important because it can represent the entire interior illuminance [39]. Therefore, we selected and analyzed indoor illuminance for the center of the space as a representative illuminance.…”

Abstract:In this study, we address the algorithm of the calculation formula from sky luminance distribution to vertical illuminance and indoor illuminance. To predict daylight, studies about sky luminance distributions and the DeLight daylight model were investigated. This paper compared three well-known sky distribution models (Perez model, Igawa model, and CIE standard sky model) with measured data. The charge coupled device (CCD) camera was used as a measurement method for sky luminance distribution. Indoor illuminance values calculated with those well-known sky distribution models are compared with measured indoor illuminance data. The following conclusions were obtained: (1) In the results of R 2 , mean bias error (MBE), and Cv(RMSE) analysis, the CIE standard sky model showed the lowest error rate with measured data. Between the Perez model and Igawa model, the Igawa model showed a lower error rate; (2) When we compared the sky classification of the Perez model and the Igawa model, both models classified the sky similarly to the CIE standard sky model in March. However, the classification of the sky in the CIE standard sky model, the Perez model, and the Igawa model differed in some of the July data because of high solar elevation; (3) The illuminance of the center point of the room was calculated using the well-known sky luminance distribution model, the Igawa model has a lower error rate than the Perez model in Korea.

“…The existence of daylight devices, i.e., fixtures that are used to harvest or guide daylight deep into the building, such as light shelves, light ducts, etc. are independently evaluated, given that they contribute to the improvement of daylight conditions, but cannot be quantitatively expressed through the daylight factor calculation [25].…”

A Methodology of Interactive Motion Facades Design through Parametric Strategies

Interactive facades are dynamic in the translation of space in architecture, especially in the aspects of aesthetics, sustainability, adaptation to the environment, and data relay through the medium of light, motion, and embedded technology. The design of interactive facades is complicated and it requires time and effort in the comprehension of the internal functions of the facade from the conceptual stage to occupancy. The existing process of modeling the experimental level of interactive facades through mock-up and prototype models demonstrate a fragmentary outline on which the final development of the interactive façade system is based on. This research aims to analyze the motion aspect of interactive facades design and simplify the conceptual and performance design process through parametric strategies using a multi-hybrid of parametric and simulation tools, such as Rhino Grasshopper, Ladybug, and Daysim, to create interactive facade designs that can verified in a virtual reality environment while generating performance outcomes that can be optimized in a holistic and improved efficient process.

“…The researchers propose different qualitative and descriptive methods illustrating the human perception of daylit space characteristics. Due to a vast number of possible light appraisal paths like linked mechanism maps and vision paths (Veitch et al, 2008;Veitch et al, 2011) and daylight evaluation indices and methods (Galasiu and Reinhart, 2008;Galatioto and Beccali, 2016;Bonomolo et al, 2017;Giarma et al 2017) the survey contained question referring to selected aspect of daylight quality criteria found in standards and environmental performance assessment frameworks like lighting control, aesthetics, uniformity, glare, control or window views ratings. The received results indicated that there were no statistically significant differences in daylight evaluations between the experts and the students.…”

“…The students' expectations for daylight were to create a pleasant atmosphere, to give as much free light as possible and to provide a view outside. These expectations relate to general criteria for the assessment or visual comfort provided by the multi-criteria green assessment systems (Giarma et al, 2017) or latest daylight standards (Mardaljevic and Christoffersen, 2013).…”

A questionnaire was conducted to investigate how 140 architecture students apprise daylight conditions within the classrooms. The participants were requested to evaluate the luminous environment and their luminous comfort. They were also asked about light preferences and knowledge on daylight metrics and regulations. The students' subjective appraisals results were compared with the experts' assessment and the on-site illuminance measurements. Later on, the students had to carry out a series of daylight indices simulations summarizing daylight conditions in their private rooms (a user's experience), and in a room, within a building, they had been designing (a designer's experience). The perception of the luminous environment was analysed against participants' comprehension of daylight simulations data. The issues students encountered during the daylight indicators analysis suggested that more coherent daylight education should be offered for future architects.
