Abstract:
Extensive documentation has been developed to support the benefits of daylight for building occupants. Recently, the high performance building industry has shown a trend towards prioritizing better daylighting conditions. In response to this trend, the Leadership in Energy and Environmental Design (LEED) rating system now addresses daylighting and views as one of the criteria for compliance. However, effective daylighting has its challenges—most importantly addressing the issue of glare. This paper discusses the issue of glare and its relationship with requirements for effective daylighting within the criteria of the LEED rating system. In this study, a LEED certified building on Montana State University's campus was considered as a case study. This paper conducts an analysis by comparing the results obtained from compliance procedures for LEED with independent evaluations of glare using simulation and post occupancy evaluation surveys. This paper concludes that the ‘illuminance simulation’ option provided in the current version of LEED (LEED v4) for compliance does not adequately address the issue of glare. This paper provides recommendations to improve the LEED rating system for indoor environmental quality which include: the incorporation of glare assessment in the evaluation procedures of daylighting and views; the use of dynamic simulations that incorporate climatic conditions in the evaluation of daylighting; and evaluating glare in early stages of design by using simulation tools.

Abstract:
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.

Abstract:
The present study investigates the effect of fixed external shading devices’ geometry on thermal comfort, daylighting and energy demand for cooling and heating in the hot and dry climate of the city of Ghardaïa (Algeria). A parametric analysis was performed by using three software: RADIANCE 2.0 and DAYSIM 3.1 for daylighting simulation and TRNSYS.17 for thermal dynamic simulation. Three shading device parameters were assessed: the spacing between slats, the tilted angle and the slats installation. The vertical shading angle “VSA” is fixed; it is equal to the optimum shading angle measured for Ghardaïa. The simulation results indicate that fixed external shading devices have a significant impact on decreasing the energy demand for cooling; however, they are unable to reduce the total energy demand since they significantly increase heating loads. It was found that fixed external shading devices remove all risks associated with glare in summer by decreasing illuminance close to the window; however, they do not improve daylighting performance in winter because of glare. We note that even if the vertical shading angle “VSA” was the same for all cases, these did not present the same thermal and luminous behavior. This is mainly due to the amount and the way that the solar radiation penetrates space.

Abstract:
Home-based workspaces have considerably increased all over the world. Besides, the recent outbreak of the COVID-19 disease forced many people to work from their homes. However, existing residential apartment buildings (ERABs) had been designed for accommodation but not for office works. Low-quality visual environments in ERABs, which have no shading controls on their windows, are evident in tropical climates with extremely high solar radiation. Thus, interior retrofit is significant to provide visual comfort for users in ERABs with low flexibility for modification of their facades. Different interior design variables were simulated by the Radiance-based program to analyse daylighting in a closed-plan room. Before the simulation experiments, field measurement of daylight was performed under a tropical sky to validate the results, and the findings revealed significant Pearson correlations. This paper showed that ERABs are confronting extremely high indoor daylight quantity, up to 10,228 lx, and low quality with intolerable glare. An adjustable model of internal shading, including an integrated Venetian blind with a horizontal light shelf and the window films, was proposed to improve quantitative and qualitative performances of daylighting in tropical regions. This dynamic model could be adjusted to various positions based on daylighting conditions in the buildings. By comparing the simulation results of this model with the base model, indoor illuminance levels could successfully reduce from 32% to 86%; Illuminance Uniformity Ratio (IUR) and Target Daylight Illuminance (TDI) significantly improved up to 180% and 300%, respectively; Daylight Glare Probability (DGP) and CIE Glare Index (CGI) changed from intolerable to imperceptible status. Accordingly, the proposed model can considerably improve daylight quantity and quality in the test room during different times. This study concludes that the dynamic model of internal shadings could provide efficient daylighting, by decreasing the extremely high indoor illuminance and glare in the ERABs in tropical climates.

Abstract:
Abstract Liveability interprets as making residents comfortable in their built environment. As daylighting becomes a necessity for human beings, daylight availability can improve the liveability of dwelling habitats, especially in high-density urban areas. Relayouting the building block without reducing the usable floor area can improve daylight availability. Kampung Braga is an example of how a heavy slum area has a low liveability quality and classifies into impoverished slum settlements at the stake of being resettled. The spatial arrangement becomes necessary to enhance the community’s quality of life. This article aims to examine how the intervention through urban layout can affect daylight availability to improve the liveability for kampung Braga. This research uses simulation methods with climate-based daylight modelling (CBDM) software to simulate daylighting with a dynamic approach. Rhinoceros for modelling, Honeybee for vertical sky component (VSC) simulation, and DIVA for daylight availability simulation. Based on the simulation on three alternative urban layouts in line with spatial plan context, it is shown that intervention through urban layout and typology of kampung Braga has shown better VSC and daylight availability values than the existing conditions. It is necessary to pay attention to the context of the building around the site when designing a specific building typology. Modifying configuration, floor height, model, and orientation show a better VSC reception and vertical facade illumination. City stakeholders need to be aware of the low liveability of the urban kampung. Planning the right urban plan design can improve daylighting availability and increase the liveability of the urban kampung.

Abstract:
Projetar sistemas de janela considerando a adequação climática envolve lidar com os efeitos do meio externo, que são dinâmicos, e com estratégias que podem ser conflitantes, tais como o controle do ganho de calor solar e aproveitamento da iluminação natural, ambos elementos provenientes da radiação do Sol. Parte-se do princípio de que isso é feito considerando o impacto de diferentes variáveis de projeto em diferentes indicadores de desempenho simultaneamente, para suporte a decisão. O estudo do efeito dessas variáveis de projeto da janela quando combinadas ainda não é consolidado, especialmente no caso de localidades de baixa latitude. O objetivo geral desta pesquisa de doutorado é avaliar sistemas de janela estáticos e dinâmicos para suporte a decisões de projeto arquitetônico, quanto a diferentes critérios de desempenho relacionados à iluminação natural e uso de energia, de forma integrada. São estudados sistemas de janela compostos por uma abertura envidraçada e proteções solares de aletas horizontais externas, fixas e móveis. O recorte engloba edificações com uso de escritório no contexto do clima quente e úmido da cidade de Maceió-AL. Para isso, simulações computacionais integradas utilizando os softwares Daysim e EnergyPlus foram realizadas, considerando o acionamento das lâmpadas apenas quando a luz natural não fosse suficiente para atender ao uso do ambiente. As variáveis de projeto analisadas foram: percentual de área de abertura, tipo de vidro, ângulo de sombreamento, quantidade de aletas, tipo de acionamento do sistema de proteção solar e orientação da abertura. As soluções arquitetônicas resultantes das combinações de todas as variáveis entre si foram avaliadas com relação à disponibilidade e distribuição da luz natural e demanda de energia elétrica para condicionamento do ar e iluminação artificial no ambiente interno, e classificadas segundo dois indicadores principais. Foram identificadas as variáveis de projeto dentre as analisadas com maior potencial de impacto no desempenho obtido em diferentes situações. Os resultados mostraram que é possível uma alternativa se encontrar em uma faixa de 10% melhores cenários nos dois indicadores ao mesmo tempo. Observou-se ainda que, apesar de a demanda de energia para condicionamento do ar ser frequentemente maior do que a demanda para iluminação, o desempenho da abertura quanto à iluminação pode ter um peso decisivo na escolha de projeto, pois este indicador de desempenho é mais sensível às variáveis da janela estudadas do que o primeiro. Por fim, observou-se que os protetores solares dinâmicos não são garantia de melhoria de desempenho em relação a sistemas estáticos.
Designing window systems in a climate responsive way involves dealing with the effects of the external environment, which are dynamic, and strategies that may conflict, such as daylight and control of solar heat gains, both elements related to the sun. This research assumes that this is done considering the impact of different design variables in different performance indicators simultaneously, for decision support. The study of the effect of window design variables when combined is not yet consolidated, especially in case of low latitude locations. The general objective of this doctoral research is to evaluate static and dynamic window systems to support architectural design decisions regarding different performance criteria related to daylight and energy use, in an integrated manner. The studied window system consists of a glazed opening and external horizontal slat-type shading devices, fixed and mobile, in offices in the hot and humid climate of the city of Maceió-AL. For this, computer integrated simulations using Daysim and EnergyPlus software were carried out, considering the activation of the lighting system only when daylight is not sufficient to meet the usage requirements. The design variables analyzed were window-to-wall ratio, glazing type, cut-off angle, number of slats, type of shading control and orientation. Architectural solutions resulting from combinations of all variables were evaluated regarding the availability and distribution of daylight and electricity demand for air conditioning and artificial lighting in the indoor environment. The solutions were then rated and ranked according to two main indicators. The design variables among the analyzed with potential of high impact in the obtained performance in different situations were identified. The results showed that it is possible an alternative be in a range of 10% best scenarios in the two criteria at the same time. It was also observed that, although the energy demand for conditioning air often be greater than the lighting energy demand, the performance of the window on daylight can have a decisive weight on the design choice, because this performance indicator is more sensitive to the window variables than the first. Finally, it was observed that the dynamic shading systems are not performance-enhancing guarantee compared to static systems.

Daylight plays an important role in building design. It affects occupant’s activities, reduces energy demand and supports human health. Most of daylighting simulation software does not capture occupant’s behavior or shading’s dynamic behavior. Daysim is the only one that calculates dynamic shading devices by using lightswitch model [1] but it has limitation. It is unable to use other automated control algorithms or capture occupant’s behavior and is also unable to simulate advanced shading devices which can only be described by bidirectional distribution function such as light redirecting films. A new framework was developed based on Radiance three-phase method to enable the capability of accurate annual daylighting simulation in a room equipped with dynamic shading devices and/or daylight redirecting devices. Two case studies are carried out using Hanoi climate to demonstrate the ability of the framework. It also considers automated shading control which allows future smart building applications. The framework is flexible to run any automated control algorithms and any dynamic behaviors from occupants. In the future, the framework will be expanded to run Radiance five-phase method.

Abstract:
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.

Abstract:
With the development of energy saving, it is needed to calculate the energy consumption of the residential building, particularly accurate dynamic energy consumption. Fixed shading devices are wildly used to save building energy because they prevent undesirable heat coming through the windows during the “overheated period”, just as in summer, which can ameliorate the indoor environments and reduce the energy consumption of air-conditioning in summer. But they will also prevent solar energy which can be used in winter to enter windows. So it is very important to be able to determine the optimal shading devices of windows. The overhangs and vertical-shading devices are representative to study the different energy performance in summer and winter, in an actual dwell house. On the other hand, fixed shading devices can weaken the effect of daylighting, so we would take both the total energy consumption and rooms’ daylighting into account. In this study, we choose several typical dwelling houses in different cities located in north, south, west, east and central region of China respectively. We calculated energy consumption of those models by using Energyplus program, and compared the shading performance of horizontal and vertical shading devices, then optimal configuration dimensions of horizontal shading devices are recommended on the basis of different requirements for solar heat gains in winter and in summer for those typical dwelling houses.

Abstract:
Energy simulation (ES) computer programs have been and still are widely used in the design and analysis of building energy systems. However, most ES programs assume that the air in the indoor building space is well mixed. As a result such programs cannot accurately predict building energy consumption for buildings with non-uniform air temperature distributions in the indoor space. They also cannot predict variations in thermal comfort levels in different parts of the building. Computational Fluid Dynamics (CFD), as a result, has become quite widely used in the design and evaluation of buildings energy systems in recent years. CFD can be used, for example, to predict the thermal comfort, natural lighting, natural ventilation, spread of smoke and contaminants in the building, and indoor air quality in a building. As a result it is proving to be an extremely valuable tool in the design of buildings and building systems. This, together with the fact that today’s commercial CFD software packages are relatively easy to use, has led to this quite widespread adoption of CFD methods in building energy analysis. Energy usage in buildings can be decreased by, for example, the use of daylighting (use of solar illumination in place of artificial lighting), by the use of natural ventilation, and by solar heating. CFD analysis provides a means of relatively accurately studying the effect of building design on the effectiveness of daylighting, natural ventilation, and solar heating. Another example of the use of CFD is in the study of the effect of various window blind arrangements on the building performance. In order for a CFD package to be used effectively in building energy analysis it should allow the use of a wide range of turbulence models, it should allow the incident solar radiation on the building to be found and used in the calculation of the indoor flow and temperature fields, it should allow the radiant heat exchange in the building to be incorporated into the calculation, and it should allow the effects of the thermal masses of the walls, floors, etc. to be easily incorporated into the calculation when they are deemed to be important. In this paper, the use of CFD methods in building energy analysis will be discussed as will some applications of CFD in building design. The use of CFD methods in developing design guidelines for particular types of buildings will also be briefly discussed.

Abstract:
This investigation presents the thermal analysis of an experimental, low energy consuming home for low-income families, located in Puerto Rico, where the prevailing climate is hot and humid. The objective of this analysis is to aid in the design of energy efficient homes, which in turn will reduce energy consumption in the Island. This investigation compares the analysis of this experimental house, specifically designed for the tropics, to a similarly sized, conventionally built low-cost home. Different construction materials are evaluated in conjunction with the use of either natural ventilation or air conditioning. The impact of natural ventilation is analyzed, with results for the inside temperature and interior heat removal presented and compared. Additional energy saving strategies are evaluated, including solar thermal energy for domestic hot water production, daylighting and the use of energy efficient lights. The annual energy consumption of the proposed experimental home is calculated and compared with the energy consumption of the conventional house. The thermal load of the house is calculated through the use of mathematical simulations of the dynamic annual cooling load using well-known software such as Energy-Plus for a TMY for San Juan, Puerto Rico. Results for the inside temperature of the experimental house, the heat loss due to natural ventilation, the cooling load when air conditioning is used, and energy consumption are presented and compared with the conventional house. Results indicate that the experimental house is 30% more energy efficient when all the energy saving strategies are considered.
