Master of Science / Department of Architecture / David R. Seamon / Kamaiya is a system of Nepalese agriculture bonded labor. In typical wage labor, one can enter or withdraw from the labor market as an independent agent; in the case of bonded labor, however, a worker cannot control his or her labor power. The Kamaiyas were liberated by the Nepalese government in 2000, and promised land to build houses. Without enough money for construction, however, many of these “ex-Kamaiyas,” as they are now called, are without housing or live in sub-standard units. This thesis examines the housing possibilities for the ex-Kamaiyas and aims at creating basic guidelines for planning and designing low-cost, self-help housing. The thesis is an attempt to design affordable and environmentally responsive housing that draws on Nepalese vernacular traditions but incorporates some modern materials and construction methods. The research and designs are based on interviews with ex-Kamaiyas living in the Nepalese villages of Tesanpur, Janatanagar, and Bhuri Gaun. The thesis serves as a guide for non-profit organizations working to provide housing for the ex-Kamaiyas and consists of guidelines, termed “design patterns,” for laying out ex-Kamaiya neighborhoods and for designing and constructing individual houses. The thesis also provides step-by-step construction guidelines for building the houses. The thesis’s last chapter evaluates the proposed housing system and identifies strengths and weaknesses.

Master of Science / Department of Landscape Architecture / Regional and Community Planning / Stephanie A. Rolley / Community development and architecture approach the study of the city in distinct ways while sharing the purpose of creating or modifying the places we inhabit. Community development utilizes a scientific approach through the study of place-making, developing it from a socially based tradition, in other words, communities of place. Architecture considers the city like a work of art approaching the study from a physical perspective and emphasizing form. Architecture in this context is both an element of construction in space and the totality of the construction, the whole of a community’s modification of site. Developed from the point of view of an architect, this investigation challenges the distinction between architecture and community development exploring each perspective’s study of the city. Through a linear progression of framework diagrams, modified as the result of connecting concepts between the two disciplines, this investigation demonstrates how architecture and community development can achieve a unified framework for the study of the city.

Doctor of Philosophy / Department of Geography / Jeffrey S. Smith / India is a country rich in religious beliefs, with a cultural landscape infused with symbolic meaning. The nation is currently experiencing great advances in development, standard of living, and connectedness to global markets and cultures. For remote communities, the spread of global ideas can significantly impact traditional customs and distinctive landscapes. Vernacular houses, meaning those particular to a region and culture, and built with local ingenuity, are vital contributors to sense of place and cultural identity. India’s remote mountainous regions in particular, are at a threshold of change in the vernacular landscape. Therefore, my dissertation focuses on Kinnaur district, of Himachal Pradesh, a remote folk region of the Indian Himalaya with a strong vernacular heritage and potential for great change in its cultural landscape. Because architecture is culturally significant and provides a clear medium in which to see changes in the landscape, the purpose of this research is (1) to determine the characteristic features of the Kinnauri vernacular house, (2) to identify the reasons for and process of vernacular landscape change, and (3) to illustrate the potential of decorative or small-scale features as significant components of place-making and enduring vernacular landscapes. My methods consisted of historical archives, landscape analysis (direct observation, photography, and drawings), and open-ended in-depth interviews with homeowners, builders, and officials. Through these methods, I distilled the characteristics of the Kinnauri vernacular house to eight distinguishing architectural features and determined the three most influential agents that directly impact landscape change and the vernacular house. My final conclusions recognize a paradox in landscape identity and that small-scale features are significant components in place-making. Furthermore, my research highlights the crucial role of ensembles and adaptability in enduring vernacular landscapes. Although homogenization of landscapes is evident across the globe, many places still exhibit individualized characteristics and cultural identity. I contend that the increased ability of small-scale architectural features to adapt to new settings, allows a modernizing landscape to preserve aspects of the vernacular architecture.

Avec l’usage élargi de la CAAO, ces outils ont été largement utilisés dans le processus de conception architecturale. En dépit des fonctionnalités avancées offertes par les systèmes de CAAO, l'utilisation de la CAAO est principalement concentrée dans les étapes de production, comme un support graphique pour le dessin, la modélisation, le rendu et la simulation. Par conséquent, il est raisonnable de considérer que la situation actuelle relative à l’usage de la CAAO dans la profession d'architecte appelle à de nouvelles améliorations. En d'autres termes, nous devons trouver un moyen de mieux intégrer la technologie et les outils de CAAO dans le processus de conception architecturale, qui est notre question de recherche. Nous avons besoin de savoir comment la CAAO pourrait être utilisée pour améliorer la capacité de conception de l'architecte. Il ressort des discussions et des recherches menées pour cette étude que nous voulons un soutien de la technologie pour nous aider à mieux concevoir et non pas que la technologie conçoive à notre place. Nous aimerions avoir un système de CAAO qui pourrait nous servir d’assistant à la conception. En étudiant la situation de l'intégration des outils de CAAO dans les pratiques actuelles de conception des architectes et en examinant les approches utilisées dans les premières tentatives de développement d’un outil de CAAO intégré au processus de conception, on peut conclure que l'approche exploratoire et heuristique serait une meilleure approche qui pourrait être adaptée pour développer un système CAAO en soutien au travail de l’architecte. De plus, une étude plus approfondie a démontré que les deux sous- approches des approches exploratoires et heuristiques (approches basées sur les cas et les contraintes), sont applicables, mais aucune d'elles n'est suffisante. Par conséquent, l’approche hybride qui prend en compte les avantages de chacune des deux sous- approches précitées serait la plus applicable. Elle nous permettrait de développer un outil CAAD qui pourrait vraiment être intégré dans le processus de conception architecturale. Cette conclusion a été vérifiée par une étude complémentaire basée sur des entrevues. / The CAAD tools have been widely adopted in the architectural design process with the popular utilization of CAAD. In spite of the advanced features that have been designed for the CAAD systems, the utilization of CAAD is mainly concentrated on the production stage of design, as a graphic medium for drawing, modeling, rendering and simulation. Therefore, it is reasonable to deem that the current situation of CAAD tools involvement in the architectural profession is calling for further improvement. In other words, we need to find a way to better integrate the CAAD tools/technology into the architectural conceptual design stage, which is our research question. We need to find out how CAAD could be utilized to improve the architect’s design ability during the conceptual design. The discussion and research conducted for this study lead to the assessment that we want technology to help us design better, but not to design for us. We would like to have a CAAD system that could help us as a design assistant. By studying the current situation of the integration of CAAD tools into architects’ design practice and reviewing the approaches that have been employed to create a CAAD tool that could be better integrated into the design process, we reach the decision that the exploring & heuristic approach would be a preferred approach that could be adopted to further develop a more feasible CAAD system. In addition, within the two sub-approaches of the Exploring & Heuristic Approaches (case-based approach and constraint approach), further study has proved that both of them are applicable approaches, but neither of them could sufficiently serve as the sole approach for this purpose. Therefore, a hybrid approach that takes advantage of both approaches would be the most applicable one because it can help us develop a CAAD tool that could be really integrated into the conceptual architectural design procedure.

Doctor of Philosophy / Environmental Design and Planning Program / Robert J. Condia / The unique contribution of Vision and the Experience of Built Environments is its specific investigation into the visual processing system of the mind in relationship with the features of awareness and embodiment during the experience of architecture. Each facet of this investigation reflects the essential ingredients of sensation (the visual system), perception (our awareness), and emotions (our embodiment) respectively as a process for aesthetically experiencing our built environments. In regards to our visual system, it is well established in neuroscience that human vision divides into the central and peripheral fields of view. Central vision extends from the point of gaze (where we are looking) out to about 5° of visual angle (the width of one’s fist at arm’s length), while peripheral vision is the vast remainder of the visual field. These visual fields project to the parvo and magno ganglion cells which process distinctly different types of information from the world around us and project that information to the ventral and dorsal visual streams respectively. Building on the dorsal/ventral stream dichotomy, we can further distinguish between focal processing of central vision and ambient processing of peripheral vision. Thus, our visual processing of, and attention to, objects and scenes depends on how and where these stimuli fall on the retina. Built environments are no exception to these dependencies, specifically in terms of how focal object perception and ambient spatial perception create intellectual and phenomenal experiences respectively with architecture. These two forms of visual processing limit and guide our perception of the built world around us and subsequently our projected and extended embodied interactions with it as manifested in the act of aesthetic experience. By bringing peripheral vision and central vision together in a balanced perspective we will more fully understand that our aesthetic relationship with our built environment is greatly dependent on the dichotomous visual mechanisms of awareness and embodiment.

Master of Science / Department of Architectural Engineering and Construction Science / Julia A. Keen / Throughout recent years, to minimize the cost of construction, a large number of multipurpose spaces have been built using lightweight, less expensive materials without considering or designing for noise control to mitigate any sound that is loud, unpleasant, unexpected, or undesired yet after construction is completed, noise issues are often evident within the space and, if severe enough, may render the intended function of the structure useless. To address this problem, this report is intended to introduce Owners and Facility Managers to some of the common solutions to resolve noise issues in multipurpose rooms. The report focuses on solutions for existing projects primarily, but it is also sensitive to budget constraints and the impact of renovation. Typical multipurpose rooms researched have a volume of 50,000-150,000 cubic feet and are expected to be used for speech activities, small music functions, and some physical sports activities. Therefore, this report will introduce the fundamentals of sound and room acoustics including interior surface materials and construction. Also included are typical noise issues from interior sources, solutions that can be taken within the building to attenuate noise, and the trade-offs associated with each solution.

Master of Science / Department of Architectural Engineering and Construction Science / Raphael A. Yunk / Today's engineers of building lighting systems must maintain a careful balance between the demands of accepted standards of practice, the necessity of life safety, the system performance needs of the client, and the developing national energy standards and certifications gaining prominence in the public eye. These sources of influence on the design process can create conflicts between the pressing need to conserve system energy usage and a costlier and perhaps unacceptable end-result for the client. In this climate, various governmental organizations and industry cooperatives have been funding published research and case-studies in order to promote sustainable design practices. Within these publications are repeated references to a "Task-Ambient" lighting fixture layout strategy. Multiple recent publications cite profound energy-saving benefits attainable using this design method. However, there is a noticeable lack of measured data concerning other qualities of this layout scheme, such as the end-user's comfort and ability to perform tasks under the resulting light distributions. Whether this lack of data resulted from the added complexity associated with such non-numerical measurements, or for some other unknown reason, this report explores this gap in the available data. An extended survey procedure was developed to approach the problem of measuring these unknown qualities of the Task-Ambient design strategy. This involved constructing multiple physical lighting layout mockups, defining the features of the Task-Ambient strategy which necessitated measurement, and designing objective tasks tailored to measure each of these non-numerical qualities. The careful analysis of this study's data results yields trends indicative of the Task-Ambient strategy, relative to a standard uniform layout, adversely affecting productivity, concentration, and the participants' subjective perceptions of the space's light distribution. The lowered level of energy use was however affirmed. The implications of these results are that the Task-Ambient strategy, while an efficient method of lighting system layout design, may not be beneficial for the client in other respects.

Master of Science / Department of Architectural Engineering and Construction Science / Sutton F. Stephens / Architectural engineers face many challenges in the design and implementation of mechanical, electrical, lighting, plumbing, and fire protection systems in buildings. Space and aesthetic coordination must be managed between the architects, engineers, contractors, and building owners. Further design issues are involved when renovating or preserving historic properties. Historic buildings often contain additional design limitations and character defining features that must be preserved. A building's character defining features often represent past history, culture, and architecture. To better understand the design coordination and other issues faced in historic renovation, three case studies located in Kansas City, Missouri, are presented to investigate the application of mechanical, electrical, and plumbing (MEP) system design into historic buildings. The three case studies include: the Stowers Institute for Medical Research, as a mechanical design; the Union Station, as an electrical and lighting design; and the Webster House, as a plumbing and fire protection design. The renovation projects' architects, engineers, and contractors were personally interviewed to obtain the most accurate information and account of the design and construction process. Additional information was gathered, and a tour of each building allowed for the pictorial documentation of each site. Preserving the historic character of buildings during renovations has many advantages and disadvantages for both the owners and the designers. The additional design parameters in historic renovation projects foster creative thinking and problem solving during the design and construction process. In order to implement a successful design, the architects, engineers, and contractors must work together and understand the value of a building's historic character during the design stage when adapting to a new usage.

Master of Science / Department of Architecture / R. Todd Gabbard / In recent years urban planners have seen critical changes in the scales, pace, and trends of urbanization, resulting in suppressed urban patterns and the emergence of distinctive types of urban dynamics. A possible interpretation of this process is that it represents a “radical socio-spatial restructuring under the regime of global neoliberalization”, a phenomenon that is being widely discussed by many influential planners, urban geographers, and sociologists. My overarching research agenda is to develop a new analytical framework for comparative quantitative analyses of neoliberal urbanization pressures that cause the emergence of distinct patters of urban dynamics and morphologies. By comparing different experiences of ongoing urban transformations around the world and studying the mechanisms of their emergence, we can identify contemporary trends, monitor critical changes and shape a better future for our cities. Using China as a basis of comparison, my thesis seeks to challenge the unproductive and homogeneous patterns of urban dynamics that emerged during neoliberalization in Russia. The controversial and extremely heterogeneous model of Chinese urbanization cannot be applied universally, but valuable lessons can be derived. My work aims to explore specifics of two different patterns of neoliberal transitions in Moscow (Russia) and Shenzhen (China) in 1992 and 1978 respectively. By focusing on detailed scales of restructuring of urban settlement typologies I identify the characteristics of socio-spatial patterns prior to confronting the transition and its resulting outcomes. While considering potential context specific properties of East Asian urbanization, I am making an attempt to extrapolate this vernacular experience into generalized theory. Connecting and quantifying local and global dimensions of urban transformations helps me build a comprehensive theoretical and quantitative framework for a more profound understanding of ongoing socio-spatial restructuring.

Master of Science / Department of Architecture / Gary J. Coates / This thesis was undertaken to investigate and seek possible architectural solutions to two issues. Firstly, fragmentation of the American family structure into a variety of new household types presents new design challenges to architects today. The single family house, once an 'ideal family' home, now needs to be redesigned to accommodate these changing lifestyles. Secondly, global warming and threats of an impending energy crisis loom large over humankind today. Environmentally-responsive architectural design can and should address both of these burgeoning problems. A program was developed as the basis for designing new infill housing in the city of Manhattan, Kansas, a small Midwestern college town. The aim was to provide dwelling units that would accommodate a wide range of family types and use patterns of the entire life cycle while fitting in to the existing architectural fabric of the neighborhood. After a literature review, it was concluded that 'front and back house' design was the most suitable option. In this context, three types of front and back house designs are presented. These options are further divided into thirteen subtypes. It is shown that these designs fulfill the spatial needs of a variety of differing households such as houses with an office, a multigenerational home and units that permit aging in place. An independent study was undertaken to achieve a 'zero energy threshold' for one of the designs within the design matrix presented in the thesis. A 60%-65% decrease in energy usage was attained in the front house and 50% in the back house by increasing the overall efficiency of the building envelope and by utilizing energy efficient appliances. Utilization of a 2 X 6.4 kW grid-connected solar photovoltaic system provided enough energy to power the house (inclusive of front & back houses). A Geothermal heating/cooling system was employed to further decrease the use of fossil fuel. With reduced energy needs and use of a gird connected solar system it was possible to achieve a 'net-zero energy house', which is defined as a house that generates as much as or more than the total energy it uses over the course of a year. An economic analysis of the front and back house and proposed energy systems was also performed. Calculations suggest that rent from the back house could provide substantial financial benefits to the owner of the front house. Although use of non-conventional energy systems demanded a larger initial investment, studies showed that savings made on the utility bills would eventually help recover this investment within the lifetime of the systems.
