A holistic approach to daylight dynamics in our built environment can have beneficial outcomes for both physiological and visual effects on humans. Simulations of how daylight variables affect light levels on the horizontal work plane are compared to their physiological effects, measured as melanopic EDI (Melanopic Equivalent Daylight Illuminance) on a vertical plane. The melanopic EDI levels were calculated in a simulated office space in ALFA software (Adaptive Lighting for Alertness) employing the daylight variables of orientation, time of day, season, sky conditions and spatial orientation. Results were analyzed for how daylight design can contribute to the physiological effects of dynamic light in office buildings. Daylight is shown to be a sufficient light source in the majority of cases to meet the recommended values of EDI and provide the suggested horizontal lx level according to the Danish Standards. A mapping of daylight conditions, focusing on the specific factors presented here, can provide guidelines in the design process and future smart building systems. The complex interrelationship between these parameters is important to acknowledge when working with daylight dynamics as a sustainable element in architecture and lighting design.

Neonatal intensive care units are a special lighting design challenge. Although natural light is highly desirable, it should be carefully planned to maximise benefits and minimise the problems associated with uncontrolled sunlight. This paper discusses the performance of different passive sunlight control strategies in a neonatal intensive care unit at the Dr. Humberto Notti Children's Hospital in Mendoza, Argentina, analysing their annual daylight behaviour through dynamic daylight simulations. The aim of this work is to optimise the use of daylight in neonatal intensive care units, considering the special lighting conditions required. Results show that, in this case study, the adequate implementation of solar control systems and the appropriate layout of the space for different uses according to surrounding building design and the characteristics of the local luminous climate can increase the useful daylight illuminance by up to 13%, while avoiding the incidence of direct sunlight at all times.

This paper aims at promoting the use of Climate Based Daylight Modelling (CBDM) and related state-of-the-art metrics by discussing a range of design options to improve daylight fruition in rooms with different orientation, shape, function, and furniture of an elementary school that is located in the Mediterranean climate of Agira (Italy). The local climatic conditions, with clear skies for most of the year, require the integration of different shading and re-directing systems with the existing envelope and rooms’ layout. Results show that the dynamic modelling is a powerful and ‘creative’ tool in the designer’s hands, which helps to inform about the choice of the most appropriate technological solutions and on their architectural integration. Comparison with mostly used static daylight metrics, such as the average Daylight Factor (aDF) and the Uniformity Ratio (UR), reveals a contrast with what would be suggested if considering these metrics alone, as prescribed by the Italian legislation. These outcomes rebate the need of performing more accurate and dynamic daylight simulations using recorded (i.e., varying) rather than fixed sky conditions to correctly inform the design process.

Abstract Studies using metrics related to dynamic sky conditions for indoor daylight performance assessment in urban environment are rare in tropical latitudes. This study applied one of these metrics, the spatial Daylight Autonomy (sDA 300,50% ≥75%, IES LM 83-12) for Cuiabá (15ºS, 56ºW, Brazil), a savanna climate city with a high frequency of partly cloudy skies. Parametric simulations were used to investigate the availability of daylight in dense urban areas. So daylight conditions inside a reference room with varied depths located within a continuous urban canyon were simulated with Radiance/Daysim in Grasshopper/Honeybee. Dimensions of the street and heights of front buildings (obstructions) are also varied in order to observe the relation between the sky angle and the sDA, for the four main cardinal directions. The results of regression analysis for this case study showed that among all evaluated parameters, room depth tended to be the most relevant for the optimization of indoor daylight. Finally, limitations of this approach and opportunities for further investigations were discussed.

Abstract Promoting the daylight performance that allows to provide visual comfort conditions by minimizing lighting energy consumption is possible with making a balance of window size, glazing type and shading strategy, which are the major design parameters of the daylighting system. Particularly, in high-rise buildings, where large openings enabling higher daylight availability and view out are preferred, the daylighting system becomes a crucial design consideration in terms of ensuring occupants’ visual comfort and improving lighting energy efficiency. This study aims to identify a proper daylighting design solution with regard to window area, glazing type and shading strategy for a high-rise residential building located in Istanbul considering visual comfort and lighting energy efficiency. The dynamic simulations are carried out by DIVA for Rhino version 4.1.0.12. The results are evaluated with the Daylight Autonomy (DA) to detect daylight availability in the space and Daylight Glare Probability (DGP) to describe the visual comfort conditions related to glare. Furthermore, the lighting energy consumption of each alternative is also analysed to determine the proper daylighting solution. The results have revealed that a proper daylighting solution providing visual comfort by improving lighting energy-efficiency can be determined by the evaluation of the daylight performance both qualitatively and quantitatively.

Daylighting presents an important role for high performance buildings. Currently, Building Information Modeling (BIM) has excelled in the Architecture and Engineering (A&E) industry as a collaboration and information exchange methodology that generates integrated computational models. Simulation plug-ins for BIM tools capable of performing daylighting simulations in a semi-automated way have been developed, thus presenting a more simplified simulation process and favoring the adoption of performance analysis since initial design stages; being a little explored subject. This article aims to investigate the Insight plug-in for Revit, focusing on its daylighting features. The workflow, input-output structure and results of Insight dynamic (sDA) and static (illuminance levels) daylighting metrics were analyzed, comparatively to the plug-in DIVA-for-Rhino, which simulation engines were considered validated by literature. Simulations on both software used the same model of a reference office space for the city of Belo Horizonte. Results indicate that Insight’s favors the daylighting analysis in the initial phases of the design process and allows the verification of code compliances, however determining materials optical properties presents some degree of complexity. Low sensitivity to glasses with low and medium values of light transmittance was noticed in the case study. Evidence of consideration of internal reflections of light rays (ambient bounces) close to 7 may leed to overestimated results in the case of low complexity models. This study intends to contribute to the understanding of the potentials and limitations of both analyzed tools, especially in regard to the specificities of BIM daylight simulation with Insight.

With the development of urbanization, more and more commercial buildings are built in cities, which is resulting in a large amount of building energy consumption that threatens the ecological environment of the earth. Lighting energy in commercial buildings occupies a large proportion of consumption, and improving the quality of natural daylight in commercial atriums is of great significance for building energy efficiency as well as improving indoor comfort. This paper proposes a method for optimizing the daylight quality of commercial atriums. Starting from the perspective of parametric design, this paper investigates the current status and theoretical research on the natural daylight of commercial atriums in cold regions, taking Jinan, China, as an example. Dynamic daylight and glare simulations were performed using Rhino + Grasshopper and Ladybug + Honeybee for every design parameter in the system, followed by correlation analysis and multiple linear regression analysis using SPSS to determine the degree of influence of each design parameter on the daylight quality of the atrium. Based on the results of the above analysis, the multi-objective optimization plug-in Octopus is used to find the combination of design parameters that can achieve the best indoor daylight. The results show that among a total of fourteen atrium design parameters, seven of them are significantly correlated with atrium daylight, and after regression analysis, it is found that the atrium design parameters affect the atrium daylight and glare in the following order: Skylight VT, Skylight ratio, Atrium inclination, Fabric coverage, Fabric VT, Wall reflectivity, Roof reflectivity. The optimal design parameters for commercial atrium daylight quality are obtained according to the Pareto front solution set, which provides some reference and ideas for improving the optimization of commercial atrium daylight in cold regions of China.

This thesis investigates the design of atria for daylighting in large scale buildings. Athree dimensional test building with a central atrium was constructed and various parameters of the atrium altered. The impact of these changes was studied through computer simulations of annual daylight distribution by implementing state of theart software. Daylight autonomy is simulated for an annual climate file for Stockholm, Sweden. In the thesis, notion is made of basic daylighting concepts, the importance of bringing daylight into buildings is argued, and the daylighting criteria of three environmental certification tools introduced. Furthermore, a detailed comparison is made on several well known daylight simulation tools. A newly developed, state of the art, daylight simulation tool called Honeybee, is used in the simulation process. The tool utilizes the calculation engines of wellknown daylight simulation software Radiance and Daysim, which apply backward ray-tracing to reach accurate results. Honeybee is coupled to the graphical algorithmeditor Grasshopper for Rhinoceros 3D, which allows for an efficient way of parametric modelling. The comparison of five different daylight simulation tools showed that Honeybee outweighs the capabilities of many of them by offering a wast range of simulation capabilities and also giving the user exceptional control of result data within multiple zones of the test building. The results of the daylight study have been compiled into a document which purpose is to serve as early stage design guidelines of atria for architects. Many factors have been shown through simulation to have a dramatic impact on daylighton an annual basis, and several suggestions have been made on how to maximize the quantity of daylight within buildings containing atria.

This thesis presents a first-of-its-kind approach and simulation of multi-chromatic LED-based dynamic lighting system that the lighting performance can be optimized by itself to less than 5% error. In this work, though the parameters we want to optimize should be calculated nonlinearly, the control of the different LEDs is formulated as a linear optimization problem via the spectrum matching strategy, which is a new way to think how to optimize a dynamic lighting system. Instead of optimizing each parameter directly, here we provide a much more time-saving and space-saving way to optimize the color rendering index, correlated color temperature and luminous flux. Consequently the lighting system can dynamically optimize the light output for greater controllability, higher color quality and luminous flux. The algorithm is also chosen from lots of studies from machine learning, computer science to numerical recipe and implemented into MATLAB to simulate the entire system. In summary, this thesis provides the foundation for future research in the areas of the spectral mixture lighting system model, efficient lighting control, dynamic utility regulation and optimization.

Daylight is the most economical and natural light source, and will differ when the location of sun, time of the day, and the weather condition vary. Dynamically simulating daylight based on the traditional radiosity method and making it a smooth animation is no easy task. We propose an approach which treats light sources in the scene as independent as a sole light source in the progressive refinement radiosity (PRR) framework. By means of performing independent PRR computation for each luminaire with which stores the shot and unshot radiosity, the radiosity of polygons in the scene due to each luminaire can be linearly combined to achieve the final image as luminaires all have being functioning in the process of energy exchange. When changing the sky parameters or simulating the daylight, our proposed method can preserve geometry information of the scene, thus avoiding recomputing the radiosity from the scratch. Therefore, rapid rendering and displaying make daylight simulation with smooth animation possible. When the user expects to observe the daylight effects within a duration of time, he can only specify the starting and ending time of the simulation and the time slot for observation. Our proposed method can effectively simulate the daylight, while performing a vivid animation for observing the lighting variation.

Daylight is one key aspect to enhance the sense of place and influence the personal interpretation and impression that last long after leaving the place. However, visual discomfort and glare can distract architects from achieving the most of daylighting. To better achieve visual comfort in daylit space time and space dynamics of the daylight condition, the representation and re-imagining of these dynamics need to be considered. This chapter explored a selected case study that was used for application: a daylit museum located in Washington DC Metropolitan was examined for visual discomfort problems. Since museums are typically carefully lit because of the sensitivity of exhibits, this case study evaluated the daylighting condition in a museum using a series of illuminance field measurements, simulations, and views experienced by occupants along a circulation path through the space. The case study also aimed at understanding how small design changes can affect visual comfort as a tactic for case studies. A collaborative design effort was used in different stages of the case study.

Shading control strategies are nowadays employed in office environments to improve the visual comfort of the user. These strategies are often solely illuminance-based whereas comfort metrics as the Daylight Glare Probability (DGP) also need luminance values. In previous studies, daylight glare has been assessed by calculating the DGP from luminance maps obtained via a luminance camera or from a High Dynamic Range (HDR) image obtained with a commercially available camera. These detectors are traditionally mounted close to the user and aligned with the viewing direction. In real office environments, this camera position is impractical, and simulations based on machine learning techniques have shown a relation between the DGP from an observer's viewpoint and the DGP calculated from a ceiling camera. This paper experimentally validates this method in a real office environment by using two different cameras and two different illuminance sensors, i.e., a low-cost illuminance sensor and a calibrated sensor. Both cameras render similar results, although one camera overestimates the DGP. Moreover, the shortcomings of the simulation results are pinpointed and the obstacles for a realistic application are addressed. Furthermore, it was found that when moving the cameras to different positions, the sun position was shown to be an informative additional input for correlating the two DGP values. In future work, additional data will be analysed to determine the performance in other weather conditions and window orientations.
