daylight in architecture dissertation

January 19, 2021

Additionally, it can decrease the electricity consumption for artificial lighting. See more ideas about architecture, daylight, light architecture. These higher preference ratings provided a first indication for possible restorative effects of daylight through psychological pathways. In a uniform research paradigm we established beneficial effects of nature, but not of daylight. To transform complex urban simulations into the simple 4-step representation, it was necessary to include simulations with i) various facade reflectances, ii) rooms located on different floors, iii) buildings with different orientations, and iv) buildings in different geographical locations. self imposed problems with technical solutions, sometimes with little success. The first chapter of this dissertation presented a review of the evidence for beneficial health effects of nature and daylight. This latter study made clear that people wanted a window at least a quarter the size of the wall, but not a fully glass wall. Twenty-five years later, in a world newly concerned about carbon emissions, global warming, and sustainable design, daylighted buildings are again proposed as a ''solution.'' as a science, though not as an art” (Hopkinson, Cook (1997) believes that the understanding of, daylighting techniques could well become an. To investigate the impact of basic urban and building design decisions on energy use and environmental performance in Northern Europe, using the central city districts of Copenhagen as references. Although windows provide daylight and ventilation, they also can allow undesirable heat gain and loss. The distribution of light is vital for spatial experience but has not been the main focus of previous research on lighting. Using the algorithms and model developed from experimental data, a visually immersive, simulation-based approach is adopted for evaluating and visualizing predictions of visual interest and excitement through space and over time. This is the first study where a shading device is controlled by a controller system with a low-resolution camera. In 2003 he was, awarded a Master of Architecture degree (with Merit). In the workplace, we have focused on automated blinds systems. v. Focus on aspects of variability in enquiry of sustainable architecture. The thesis emphasizes the importance of two factors, when we talk about light, architecture and health, namely the differences in light during the day and the clear, low-iron glass. In the case of sustainable building, governance projects and experiments must tackle challenges of measurement, consumer base, and rapidly evolving technologies. The dissertation is organised in four main sections: Prologue, Light Characteristics, Light Modelling and Epilogue. The use of the daylight coefficient approach to both accurately and efficiently predict hourly internal daylight illuminance levels for an entire year is described. the building (Source: Copplestone, 1997:70-71). Some historical precedents are offered as, examples of projects in which designing to maximise. uorescent lighting, there were a few twentieth, ectors (Figure 3) which redirect light from an, rstly in quoting Le Corbusier - “I use light, rst time in history attitudes towards energy, oor level of the room, and the transparent. However, none of them can consistently and accurately explain the large variation between subjects’ discomfort glare perception. Paper I reports on a study on the simplified representation of the structure of the streets and buildings in cities. Part II describes verification of improved models of MRT and daylighting implemented into the simulation tool IDA ICE, which is one of the steps to make the integrated design method practically applicable for building designers. For example, such as darkrooms and basement shops, bars, and restaurants, there are strict requirements, for the design of workplaces. This property of daylight coefficients is exploited to yield hourly internal illuminances for a full year as a function of building orientation. These photoreceptors are the primary mediators of ‘non-visual’ responses impacting human health, from resetting the circadian clock to directly alerting the brain. The large degree of scatter that is observed when subjective evaluations of glare sensation are compared against calculated glare indices suggests that discomfort glare may be dependent on other variables beyond the physical and photometric parameters that are commonly embedded in glare formulae (e.g., source luminance, source size, background luminance, and position index). By contrast there is also discussion relating to the 'the lost art' of using natural lighting in architecture. The second article addresses structurally influencing the building users towards sustainable consumption – so that by design, people may behave more sustainably in buildings. Then, the trends of light atmosphere in Denmark are investigated and light zones at the hospital ward defined in order to optimize the illumination. During the last decades, light has become an important research topic for engineers, chronobiologists and neuroscientists. She cites, research in this area carried out by Lewy et al, (1980), and points to other research, in which, the psychological effects of natural light have, been explored. tracking mirror and prism systems (heliostats). give rise to better architecture. and psychological wellbeing” (Hughes 1983). For this purpose the thesis develops a new method of representation, si­multaneous-timelapse-photography, depicting differences in the light over time and space, according to E, S, W and N, depicting the differences in the light respectively at summer solstice, equinox and winter solstice. Hence, discomfort glare from daylight should be predictable. By focusing on users’ experiences and interpretations, relationships between the distribution of light and perceived spatial dimensions and experienced spatial atmosphere have been investigated. The power of place: how our, surroundings shape our thoughts, emotions and. The expressive interface might be essential for the successful adoption of the intelligent systems of the future. A dynamic wavelength-dependent model framework is proposed to evaluate the non-visual health potential of light. How places affect people. iDbuild combines the thermal and daylight calculation engines for integrated analysis. In Northern European climates, visual discomfort is the most negative side effect from windows. Visual data analysis techniques are used to display and process the massive number of derived illuminances. Also, excessive short-wave directly-transmitted solar radiation and long-wave indirectly-transmitted energy can cause thermal discomfort and an increased energy demand for cooling. These effects of light are transmitted via a novel class of photoreceptors in the mammalian retina, which was discovered only a decade ago. The paper addresses two main issues: (i) a range of core-daylighting systems, and (ii) the findings from a survey of New Zealand architects (approximately 1 in 3 of those listed in the Architects Education and Registration Board register). Ander (1995) makes a strong plea to building, and for all disciplines to become involved at, an early stage in the design process. The DGP is also used as a basic glare descriptor for new climate based glare evaluation methods, which enables an assessment of daylight glare for a full year data set within a design process. Effective use of the inter-reflection calculation is described. On the contrary, ignored, and above all a feeling of alienation, was being experienced by the inhabitants of, In spite of technological developments such as, century architects for whom there could be no, compromise, and who recognised the crucial, role played by natural lighting in their work. A uniform research paradigm was chosen to test these effects; ego-depletion. How places affect people - Buildings have a huge influence on our mood and performance. This thesis reports on four years of research with the aim to contribute to the implementation of low-energy office buildings with high quality of indoor environment and good total economy. people occupying windowless environments. ALNUAIMI-THESIS.pdf ( 13.7 MB) Suwon Song, "Development of New Methodologies For Evaluating The Energy Performance of New Commercial Buildings", 2006. The first stage was conducted within a laboratory setting, and sought to examine temporal effects under controlled artificial lighting conditions. The objectives stated in the thesis aimed at broadly assessing the applicability of CBDM by looking at multiple aspects: (i) the way CBDM is used by expert researchers and practitioners; (ii) how multiple state-of-the-art simulation techniques compare to each other and how they are affected by uncertainty in input factors; (iii) how the simulated results compare with data measured in real occupied spaces. Initially, office workers in eight different buildings in the Netherlands were questioned on the quality of their workplace concerning the office, the lighting and the view. Therefore, this dissertation aims at pointing to the opportunities provided by daylight apertures to interact with the Nordic light. The causal directionality of this relation was further investigated for natural environments by guiding the valence of associations. The illuminance calculation is validated under real sky conditions for a full-size office space. Six percent of New York residents suffer, severe depression during winter, but as many. Such designs generally encourage daylight to penetrate a building but in some cases the goal is to reduce its degree or intensity. These time series of light quantities serve as inputs for the light-driven model, which accounts for light intensity, duration, history, and timing of light exposure. Using a closed room versus a room with openings, it is shown that differences can be measured in secretion of the hormone cortisol, which is a stress hormone as well as an immune regulatory hormone, but no differences can be measured in the reaction of the other stress effector system, the sympathetic nervous system. First, we wanted to test whether daylight and natural environments share underlying psychological mechanisms. Here the thesis presents a new concept, the unhealthiness factor of glass. Thus, an understanding of how systematical variations in architecture through a welldefined physiological mechanism can influence health, healing and well-being is successfully established. By quantifying light in terms of spectral effectiveness and temporal dynamics, different light exposure patterns can be ranked in terms of its potential to have an impact on human health. For both natural environments (Chapter Three) and daylight (Chapter Four), little evidence for restorative effects of the manipulation was found. One example, is the fully glazed greenhouse ceiling/roof, at the Cambridge University History Faculty, building (James Stirling, 1967). The thesis can be downloaded here. In this assessment we focus on the energy-related savings definitions, recognizing that there are overlapping elements in each definition. The PhD’s first article delves into how Active House goes about legitimating technical specifications (i.e. These range from. The second cycle explores the users’ preferences and trends of light atmosphere in four exploratory studies. Barrett visited the continent to monitor, construction, and the experience of living in constant, daylight, with no apparent diurnal-nocturnal rhythm, to pace daily activities, led to an interest in the, by natural light (or its lack), and in particular the role, played by architecture in this process. Gallagher, W. (1999). MacLaughlan, J., Anderson, M., & Hollick, F. (1982). Architecture, Victoria University of Wellington. In both chapters, the ego-depletion inductions were not always successful. It is this change that gears them towards making more sustainability-oriented consumption choices in the future. This means that in the design process the architect’s responsibilities outweigh those of the engineers. Whether it’s used in the diffuse illumination of a museum gallery or as a dramatic and variable figure within an enclosed space, the formal and architectural intentions of daylight should be … We therefore propose to improve the acceptance of automated blinds by making users aware of how the system works and how its use affects energy consumption. However, this assessment also requires attention to architectural design, maintenance, economics, and energy issues. Is it enough information to provide an illumination, which the patient can experience as homely and pleasant? Moreover, a series of laboratory studies was performed to explore effects of bright light exposure during regular daytime hours on self-report, task performance and physiological arousal measures. Be it in the form of an asymmetric planning of building form, facades, apertures or artificial lighting. These early decisions concern the work of architects involved in the initial design phase. The findings also show that brightness not only contributes to our experiencing a space as more spacious than it really is, but in certain situations brightness can actually have the reverse effect. rmly within the arena of the psychologist. Perception and lighting as, formgiver for architecture. The “Space” aspect looks into the dimension of the space, geographical orientation, interior design, composition of the space, materials, surfaces and objects. Whether it’s daylighting or artificial lighting, light draws attention to textures, colors, and forms of a space, helping architecture achieve its true purpose. The research results show an impact from urban form on building energy consumption which is much greater than previously thought, more precisely described, and more dynamic in character as daylight is taken into account. On the other hand, in Chapter Three, we found that generating positive associations resulted in an improved restoration of positive affect. Even more, it allows designing not only the building itself, but also the CFS, the artificial lighting and the control algorithms. He can be contacted, Surveys conducted by the State of Florida Energy Offices Energy Conservation Assistance Program (ECAP) at the University of South Florida, over a 13 year period on a national basis, have, with repeatable results, shown that regardless of Longitude and Latitude, Passive and Active Daylight Harvesting Systems can significantly reduce conventional lighting loads with no adverse effects on a, With the subject of good lighting conditions commanding wide-spread attention, the debate over the value of full-spectrum fluorescent lighting needs to be looked at more closely. The vision of creating balance between the consumption and production of energy in our build environment has created ambitious energy targets and requirements in the building regulations, which has accelerated the development of new energy optimized technologies and components. In recent years programs like Grasshopperand Generative Components2 have made parametric tools with visual programming interfaces accessible to architects at low cost. Discomfort glare is considered to be an annoyance or distraction caused by sources of non-uniform or high luminance within the field of view of an observer. Ruck, (1989) emphasises the important role played by, daylight in the design of architecture, and she, considers it to be as much a ‘material’ as the, brick, steel, stone and concrete, of which the, solid fabric of the building is made, and should, Gallagher (1994) suggests that the Industrial. In reality, though, and as a consequence of this technological, advancement, the art of using natural light, in an architectural manner was rapidly lost to, architects practising in the middle and second, half of last century. Two of the prime attributes of daylight in Singapore and an equatorial climate––patterns of light through trees and colour renditions of the built environment due to changing colours of the sky––are currently not represented in daylight prediction workflows. Interestingly, luminance distribution was not only found to impact on visual comfort but also on subjective alertness, mood and well‐being. The aim is threefold: (1) to unfold the link between building energy use and urban density, typology and fabric; (2) to analyse how technical scientific knowledge can be integrated in early urban planning and design decisions (IED); and (3) to show the architect’s responsibility and opportunities to rethink their architectural role based on new goals and knowledge. Zealand: Department of Building & Housing: Author. The model “Light Atmosphere” is the focal point of the project through iterative process and also developed through the study. Paradoxically, the new found. The fourth cycle evaluates the effect of the light atmosphere at the ward. At the, time of writing Hopkinson et al noted that there, had been little research into the behavioural, aspects, and they could only therefore surmise, as to the reasons. Efficient artificial light sources and fully glazed facades have liberated designers from these constraints of the past. The climate-based simulations consisted of annual simulations of the daylight conditions. The experimental setups have also shifted from scale models to real-life interior and exterior settings. Research efforts in discomfort glare perception from daylight should therefore aim at improving prediction models by looking at other potential factors, such as physiological and environmental ones. most recently discovered realm of architecture. Natural light is a dynamic and ephemeral tool for expressing the quality of space. The aim of this thesis was to assess the impact of office lighting on visual comfort including NIF effects. these valuable variations” (Evans, 1981:21). Proceedings from Daylighting, Stegers, R. (2008). Therefore, it is becoming increasingly central to develop more holistic approach to enquiry and thereby the understanding of sustainable environments is viewed in balance between perceptual qualities as well as technical abilities. Through these I have developed methods, concepts for collaboration, cross-disciplinary research, education, industry, technology, developmental environments and practice in the process of developing energy producing technologies, components and buildings with architectural potentials. But great environmental performance differences among building typologies within this range indicates that there is plenty of design opportunity to improve environmental performance of buildings by working with urban design, building form and orientation and the geometry and properties of the building skin. external temperature conditions. In addition, research has shown acute activating effects of bright light exposure on subjective and objective indicators of alertness and arousal. Some of the reasons for this loss of conviction and expertise are considered. For these simulations, the luminance distribution of the sky was described by the Perez all-weather sky-model, based on hour-by-hour input of direct and diffuse irradiance from weather data files. The DGP describes the probability that a person is disturbed by daylight glare. Four sky models and two sky models blends are assessed. The dissertation can be downloaded from the website of the university library:, Integrated Energy Design in Masterplanning. It was sent in response to the author’s, enquiry about the NZBC, Section G7, and as, to any changes to this regulation that may be, being contemplated. measurable parameters) for comfort in buildings. Case studies of buildings with good daylighting design are analyzed. Considerations of daylight control from several important view points, the quantity and quality of daylight, daylight and visual comfort, orientation of buildings for daylight, daylight design in planning of various buildings for different purposes, such as school, hospital and house, have also been discussed in the article. Anne Iversen’s thesis can be downloaded at, ARCHITECTURAL EXPERIMENTS. Psychological mechanisms were further investigated in Chapters Three (for nature) and Four (for daylight). Ruck, N.C. (1989). Therefore, we developed a control strategy that is based on the comfort requirements of the users. In lighting design it is accordingly necessary to take into account not only luminous intensity, but also light’s spectral composition, since the novel class of photoreceptors is more maximally sensitive to different luminous wavelengths than the classical photoreceptors (e.g. One method through which this is achieved is by testing the ability of visual comfort analysis to resolve subjective occupant comfort. This meant that the weather data files used had an important impact on the simulations. This thesis focuses on the relationship between light and health in architec­ture. As, discussed earlier, Gallagher (1999) and Cherulink, (1993) believe that architects need to show, behavioural research, and to be more proactive, There is something of a grey area in all of this, to be asked, “how far can the architect go in, assessing and judging user needs, or is this the. The main research question that this study aims to answer is to determine whether one of these factors, namely the socio-environmental context of the subject, influences discomfort glare perception from daylight in office buildings. “Over and over again I, have seen architects skip over the theory and, insight of an architectural program to go straight, to the square footage listing - “how big do you, want the room” is the concrete level at which. Integration of building systems and architectural design with sunlighting equipment is covered; programming, analysis, computer models, and postoccupancy evaluation are stressed.
