Advances in the material sciences continue to provide designers with a wealth of new materials that challenge preconceived notions of the building envelope and its performance. These new technologies can be used to create new adaptable building skins and allow for an active interaction with the environment to reduce energy consumption in buildings. This thesis investigates the function of the building enclosure in relation to these new material developments and recent changes in the treatment of the building envelope. New glazing, insulation and thermal storage technologies are discussed in the context of their technical trajectories. Based on th is discussion of functions and technologies, a specific set of materials is selected and their combination into a facade panel is proposed. Th is new element is a layered facade component including electrochromic glazing, aerogel and a phase change material. The combination is analyzed for its potential as a translucent thermal storage wall in the context of American residential construction. Aspects of performance, integration and design are explored through calculations, experimental testing and the creation of scaled models and a prototype element. For this purpose an environmental test chamber has been built on MIT's campus to evaluate the performance of new facade elements. The result of this study shows the potential for such innovative facade concepts and points towards areas of future research to make such concepts technically and economically feasible. In particular, the need for better tools to evaluate the performance of such advanced skins is identified in order to achieve successful implementation of these new technologies and ideas.

Full textEl principal objetivo de esta tesis es el diseño, construcción y caracterización de un sistema de concentración solar formado por dos lentes cilíndricas holográficas y una célula fotovoltaica de Silicio para integración arquitectónica en fachada. El uso de Elementos Ópticos Holográficos (EOHs) en lugar de elementos refractivos o espejos supone ventajas como la selectividad cromática y la facilidad de integración en fachada. Por otro lado, es necesario realizar seguimiento en una dirección. Los EOHs han sido diseñados de forma que se acopla el espectro solar con la respuesta espectral de la célula para obtener una concentración óptica máxima en el rango espectral deseado y por lo tanto, corriente eléctrica máxima. Se ha desarrollado un algoritmo de trazado de rayos basado en la Teoría de Ondas Acopladas para analizar local y globalmente EOHs y sistemas holográficos. Las simulaciones han sido validadas con resultados experimentales de EOHs registrados en fotopolímero Bayfol HX. También se han estudiado EOHs que operan en el régimen de transición entre el régimen de Bragg y el de Raman-Nath, observándose las ventajas que ofrece para aplicaciones de iluminación con espectro ancho.
The main objective of this thesis is the design, construction and characterization of a solar concentrating system formed by two cylindrical holographic lenses and a Silicon PV cell for the scope of façade building integration. The use of Holographic Optical Elements (HOEs) instead of refractive or reflective elements implies advantages such as chromatic selectivity and ease of integration on a façade. On the other hand, tracking is necessary in one direction. The HOEs have been designed to couple the solar spectrum with the spectral response of the PV cell in order to provide maximal optical concentration on the target spectral range and therefore maximal electrical current. A ray-tracing algorithm based on Coupled Wave Theory has been developed to locally and globally analyze HOEs and holographic systems. Simulations have been validated with experimental results of HOEs recorded on Bayfol HX photopolymer. HOEs operating in the transition regime between the Bragg regime and Raman-Nath regime have also been studied, showing the promising advantages it offers for broadband spectrum illumination applications.

Full textwas used to determine the severity, the incidence, and location of defects within each house type. Houses less than a year old were found to contain a siginificant proportion of defects for both types of builder. In addition, it was found that HO builders had a mean of 2.74 defects per house and HR builders mean of 2.30 defects per house for the seven-year warranty period. To determine whether there was a significant difference between the quality of housing produced by HO and HR the statistical technique of Chi-squared analysis was undertaken at a 5% level of significance. The analysis revealed that there was a significant difference between the quality of housing procured by owner
builders. In particular, it was found that the important category of workmanship for HO builders had significantly less defects that HR builders, which suggests that HR builders need to improve their managerial practices and the quality of on-site supervision. In essence, this thesis has provided a series of benchmark metrics for latent defects against which current and future legislative programs con be compared for new housing in the State of Victoria. It is recommended that future research focus on the methods for improving the role of the on-site supervisor as they are considered to be the important link in the quality chain.

The plate formulation based on Reissner's hypothesis, which can be used either for thin or thick plates, is extended to model building floor structures which is represented by a zoned plate, where each sub-region defines a slab or a beam. The beams are modelled as narrow sub-regions with larger thickness. The integral equations are derived by applying the weighted residual method to each subregion and summing them to obtain the equation for the whole body. Initially the values are defined on the interfaces and external boundary. Then, in order to reduce further the degrees of freedom, the interfaces values are translated to the the beam axis. The accuracy of the proposed model is confirmed by several numerical examples whose results are compared with the analytical solution if it exists or with a wellknown finite element code.

Results from the analysis of how loads affect the building are compared with results from the corresponding analysis of a conventionally produced volumetric element and how vertical loads as well as wind loads affect its design. In the study, the forces that the building is exposed to are examined and the connection between wall and floor joints is designed. The forces and torque a construction built up of volume modules is exposed to are also presented. In the study the connection between the floor joints and the supporting wall is designed according to Eurocode. A comparison is presented with respect to the load carrying capacity of a volume module with CLT and a conventional load bearing frame.

Full textImportant thermal insulation levels can prevent the building to cool down during the cooling period, when the external conditions are favorable. In this thesis, the concept of switchable insulation is developed: during the cooling period, the insulation can be deactivated during the night to let the heat flow out. During the heating period, the switchable insulation can be deactivated whenever solar gains can be used. In this thesis the potential of switchable insulation for an European continental climate and for office buildings is investigated. Also, two new concepts of switchable insulation are introduced, developed and characterized experimentally. A detailed thermal model has been introduced, validated and used for a parametric analysis. The potential of switchable insulation is investigated on a building level, showing that important reductions of the heating and cooling load as well as summer discomfort hours can be achieved. Several control strategies have been developed, introduced and compared. The influence of thermal mass was also investigated, as well as the influence of the orientation or the elements’ frame

Esse trabalho trata da análise linear de flexão de pavimentos de edifícios utilizando o Método dos Elementos de Contorno. A formulação de placas baseada nas hipóteses de Reissner, que possibilita a análise de placas finas e moderadamente espessas, é estendida a fim de se modelar pavimentos de edifícios. Nesse modelo, o pavimento é representado por uma placa composta de sub-regiões, sendo cada subregião a representação de uma placa ou viga. Assim, a viga é modelada por uma subregião de pequena largura e maior rigidez. As equações integrais dos deslocamentos são deduzidas utilizando-se o Método dos Resíduos Ponderados. Inicialmente as variáveis são definidas ao longo das interfaces e contorno externo da placa. Então, a fim de reduzir o número de graus de liberdade do problema, apresenta-se um modelo alternativo onde as variáveis ao longo das interfaces são escritas em função dos valores nos eixos das vigas. A validação da formulação proposta é feita através de exemplos, cujos resultados numéricos são comparados com valores previstos analiticamente ou com valores obtidos numericamente a partir de um software comercial baseado no Método dos Elementos Finitos.

Full textIn this work, the plate bending linear formulation of the boundary element method - BEM, based on the Kirchhoff\'s hypothesis, is extended to incorporate beam elements. The final objective of the work is to obtain a numerical model to analyse building floor structures, in which stiffness is further increased by the presence of membrane effects. From the boundary integral representations of the bending and the stretching problems a particular integral equation to represent the equilibrium of the whole body is obtained. Using this integral equation, no approximation of the generalized forces along the interface is required. Moreover, compatibility and equilibrium conditions along the interface are automatically imposed by the integral equation. An alternative formulation where the number of degrees of freedom is further reduced is also investigated. In this case, the kinematics Navier-Bernoulli hypothesis is assumed to simplify the strain field for the thin sub-regions (beams). Then, the formulation is extended to perform non-linear analysis by incorporating initial effort fields. Then non-linear solution is obtained using the concept of the local consistent tangent operator. The domain integral required, to evaluate the initial effort influences, are performed by using the well-known cell sub-division. The non-linear behaviour is evaluated by the Von Mises criterion, that is verified at points along the plate thickness, appropriately placed to allow performing numerical integration to approach moments and normal forces using Gauss point schemes.

Full textThe Southern African Institute of Steel Construction expressed concern with regard to the unit definition of the effective length factor, K, stipulated for compressive elements of parallel chord trusses in Clause 15 of SANS 10162-1:2005 - Limit state design of hot-rolled steelwork. The simplified method for truss design specified in the code assumes all compression members are pin-connected, which allows for greater design simplicity and reduces the amount of code interpretation required by the designer. In addition to this, Clause 15 requires the additional reduction in resistance of the first web compression members by a factor of 0.85. However, this approach may be considered overly conservative and in current design practice the effective length factor is often reduced to less than 1.0. This research investigates the effective length factor of web compression members in parallel chord trusses, by means of investigative structural analyses of representative trusses using ANGELINE and Prokon analytical programs, and by designing, constructing and testing six representative trusses, using current design practices. A comparative study of a number of different countries’ codified approaches to truss design is also included. The structural analyses revealed that in-plane buckling of the web compression members was the consistent mode of failure, however at a much greater applied load than the design load determined according to SANS 10162-1:2005. Contrary to the expected mode of failure, all six tests performed on the representative trusses exhibited elastic out-of-plane buckling, or strongaxis buckling, of the web compression members, but still at a much greater applied load than the design load. The unexpected out-of-plane buckling of the web members is due to the inplane stiffness of the end connections used. In order to stay true to current design practice, gusset plates and longitudinal welds were used to join the web members to the chords. The stiffness of the gusset plates therefore significantly reduced the effective length of the web compression members in-plane, but did not reduce the effective length out-of-plane. Despite the unanticipated behaviour of the tests performed, certain conclusions can still be drawn from the results. The unit definition of the effective length factor for in-plane buckling of web compression members is too conservative and a K factor of 0.8 is recommended. In addition to this an effective length factor for out-plane-buckling of web compression members of 1.1 is recommended for trusses with welded connections. The necessity of the reduction in resistance of 0.85 of the first web compression members requires further investigation. The most important conclusion to be drawn is that out-of-plane buckling of web compression members can be the dominant failure mode, which is not taken into consideration in current design practice.

The project mainly focuses on the thermal study cover, because this is a part of a building that receives and absorbs large amounts of energy by solar radiation, directly influencing the internal temperature of the building and this can cause internal temperatures of discomfort, which can even cause injury on the health of users, and also the economy, for the use of internal air-conditioning equipment in order to eliminate the thermal discomfort causing higher consumption of energy. The study was conducted by the installation of equipment that collects data from temperature automatically. They were monitored different areas of the interior of four experimental cells and a test prototype of popular house occupied. Was selected a representative day for the climate analysis, of the surface temperatures and internal air temperatures. The temperature results of the four test cells (Ibaplac tile-wood ceiling, Ibaplac tile-ceramic ceiling, asbestos tile-ceramic ceiling, ceramic tile-ceramic ceiling), and the prototype (Ibaplac tile-Ibaplac ceiling) was compared in order to determine the thermal behavior on heat of the roofs systems, compared an alternative roof system with an conventional roof systems, also analyzed in this research. .A data analysis of the thermal behavior of the roof systems under study was conducted in accordance with its thermal response in heat representative day, determined for examining period of measurements, in addition to the use of excel spreadsheets and graphics compiled from data collected by the automatically acquisition system of data \"datalogger CR10X\" and satellite GOES images obtained from the Internet.

Full textand some historical traditional construction materials of Anatolia as timber, masonry and infill brick, lime based exterior and interior plasters. The results were evaluated in terms of material properties of AAC, the compatibility of AAC and its complementary elements with each other and with the historic timber framed structures in Anatolia. It was concluded that the use of AAC in repairs of historical structures could be discussed only if the original infill is lost. In addition, its cement-plasters should be avoided from the historic fabric since they introduce salt problems to the structure. In terms of vapor permeability and modulus of elasticity, water repellent finish coat was proper finishing for AAC, and AAC, especially G4, exhibited similarities with historic infill mud brick. Further studies on other compatibility parameters were, however, necessary to decide on the compatibility of AAC with its neighboring materials. Moreover, the integrity of AAC with the historic fabric needed improvement by increasing its pozzolanicity and/or producing a new intermediary repair mortar/plaster.

For both case studies, three models are implemented, before and after the retrofitting, which are characterized by an increasing level of detail: model A with only structural components, model B with external infill panels modelled as equivalent connecting struts according to literature, and model C with external and internal infill walls calibrated through the results of in-situ dynamic tests. As regards the pre-retrofitting phase, the calculation of the seismic vulnerability index was carried out by means of nonlinear static analysis (pushover). As for the post-retrofitting phase, the calculation of the seismic vulnerability index was carried out by means of non-linear dynamic analysis (I.D.A). The results are shown in terms of comparison between the capacity curves obtained with push over analyses (pre-retrofitting) and with incremental dynamic analyses for the different model. In addition, the outcomes are shown also in terms of intensity level of the seismic action necessary to reach a predetermined limit state for model A, model B and model C.

Full textThe present work concerns the use of shade elements as architectural elements to block sunlight in public buildings. In a city like Natal, (5o South) the incidence of sunrays in any type of design should be a constant concern for all the architects. Besides, this habit of avoiding insolation in the environment is not a common practice. Within this context, the present work has the objective to dig deep into the knowledge of solar control, studying some cases and verifying its function according to the orientation and the original design of the building, having in mind if the shade elements usually used in the region have achieved their purpose of providing protection against the incidence of direct sun rays. This study considers the position of the shade element (horizontal and vertical), the angle formed between them and the respective facades, and the local of the buildings in relation to their orientation during the summer, winter and equinox solstice. As supporting instruments the solar map of the city and the protractor, for measuring shade angles, were used. It was concluded that in all the cases studied, it was not possible to obtain the maximum use of the elements. It was verified that the best type of shade element (more efficient) for the city of Natal is the mixed type (horizontal and vertical) and that the vertical shade elements are more efficient in the early mornings and late afternoon. The horizontal shade elements are used more effective at midday. We intend to present the results of this study to the architects in the region in order to show them the correct ways of using the shade elements according to the possible orientation on the facade, as a supporting tool at the time of designing a project as well as a subsidy for further discussions on the elaboration of the new urban standards for the city of Natal/RN
O presente trabalho apresenta o uso de elementos arquitet?nicos como forma de prote??o aos raios solares em edif?cios p?blicos. Em uma cidade como Natal (5? sul), a incid?ncia dos raios solares em qualquer tipo de projeto deveria ser uma preocupa??o constante para todos os arquitetos. Entretanto, o h?bito de proteger a edifica??o da insola??o n?o ? uma pr?tica comum. Dentro deste contexto, esta pesquisa tem como objetivo se aprofundar no conhecimento do controle solar, estudando alguns casos e verificando sua funcionalidade de acordo com a orienta??o e seu desenho original, tendo em mente que os elementos de sombra geralmente usados na regi?o t?m o prop?sito de dar prote??o contra a incid?ncia direta aos raios solares. Este estudo considera a posi??o do protetor solar (horizontal e vertical), o ?ngulo formado entre eles e as respectivas fachadas, al?m do local da edifica??o em rela??o a sua orienta??o durante os solst?cios de ver?o e inverno e equin?cio. Como instrumento de apoio foram utilizadas as cartas solares para a cidade e o transferidor de ?ngulo de sombra. Conclui-se que em todos os casos estudados, n?o foi poss?vel obter m?ximo proveito destes elementos. Foi verificado que o melhor protetor solar (mais eficiente) para a cidade do Natal ? o do tipo misto (horizontal e vertical) e que os elementos verticais s?o mais eficientes no come?o da manh? e final da tarde. Os elementos horizontais s?o mais eficientes pr?ximos ao meio-dia. Pretende-se apresentar os resultados deste estudo aos arquitetos da cidade para indicar as formas corretas de uso de elementos de prote??o ao sol, de acordo com a possibilidade da orienta??o da fachada, como ferramenta de aux?lio ao projeto, como tamb?m, que esta pesquisa possa servir de subs?dio para futuras discuss?es na elabora??o do novo c?digo de obras para a cidade de Natal/RN

Full textThe housing policy conducted over the past two decades has resulted in an increasingly segregated city center in Stockholm. The abolishment of housing subsidies in the 90s led to a historic low rate of construction and an urban development unilaterally directed towards the wealthy. Parallel to this, much of the housing stock has been converted to condominiums which caused many relatively cheap rental apartments in older buildings to disappear from the stock. These are difficult to replace with new housing, as they are more expensive. The core issue is of course that it is expensive to build houses and assuming that the current housing policy will last, it is highly relevant to develop cost-effective construction methods in order to make possible apartments with affordable rents that can help to combat segregation over time. Our proposal consists of a residential building in Stadshagen. The property is divided into two buildings that are linked together by a system of access balconies connected to a stairwell. The houses are constructed with volume elements stacked on a concrete base. The design of the elements is based on shipping containers which provides a rational construction process and a high degree of prefabrication. The base contains an underground entrance, a business premise and common areas for the residents. The apartments are available in three sizes whereof the larger apartments have two floors.
