Spirit of place and the evolution of the vernacular house in Kinnaur, Himachal Pradesh, India

Belz, Melissa Malouf January 1900 (has links)
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.

Vision and the experience of built environments: two visual pathways of awareness, attention and embodiment in architecture

Rooney, Kevin Kelley January 1900 (has links)
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.

Multipurpose room interior noise control for owners and facility managers

Seip, Clare Elizabeth January 1900 (has links)
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.

Task-ambient lighting: a sustainable design method investigation

Caton, Nicholas A January 1900 (has links)
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.

Incorporating mechanical, electrical and plumbing systems into historic preservation projects - three case studies

Terry, Jason January 1900 (has links)
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.

Urban systems dynamics and emergent morphologies under the neoliberal socio-economic restructuring: Moscow and Shenzhen as case studies

Smirnova, Vera January 1900 (has links)
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.

Zero-energy infill housing: front and back house options in Manhattan Kansas

Pradhan, Trishna Rani January 1900 (has links)
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.

Incorporating new age technology into campus lighting

Matlack, Daniel W. January 1900 (has links)
Master of Science / Department of Architectural Engineering and Construction Science / Raphael A. Yunk / Sustainable design and green engineering practices have become a priority in the architectural design industry over the past few years. Energy codes and standards have become more stringent as energy costs rise and buildings become larger, consuming more energy and having a larger impact on the environment. One major area for improvement to meet these new requirements is in the lighting area. Kansas State University (KSU) in Manhattan, KS has had the same campus walkway lighting system for over 50 years and it does not meet the current energy codes and standards. This paper will perform a case study of the current walkway lighting system on the KSU campus, specifically focusing on the Quad area and applying the same principles to the entire campus. The illumination and fixture distribution characteristics will first be established and analyzed to determine an accurate baseline for later comparison. Issues regarding the illumination, efficiency, aesthetics, maintenance, and landscaping will be addressed once the current conditions are established. Lighting technology has changed dramatically in the past year with the development of high efficiency fluorescent, induction, and light emitting diode (LED) lighting. New LED technology has proven to be the most efficient and has been adapted to create outdoor LED fixtures that could help KSU surpass the current energy standards and improve the overall quality of light to correct some of the current issues the existing lighting creates. A full analysis of the illumination, efficiency, aesthetics, and economic feasibility will be performed. The economic analysis will compare existing maintenance and energy costs to that of the first-cost with maintenance, and energy costs to determine an estimated payback. Once the analysis is complete, future options for KSU to implement new lighting technology will be discussed. By creating a more environmentally conscious campus, using high efficiency lighting, KSU could set an example for other universities to pursue sustainable technology and design.

A change in perspective: new priorities for neighborhood design in Johnson County, Kansas

Vogel, David L. January 1900 (has links)
Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Timothy D. Keane / The fundamental purpose of this project, a suburban infill endeavor in southern Overland Park, Kansas, is to create connections on a number of levels and scales through the implementation of traditional neighborhood design principles within the context of the natural and man-made conditions affecting the site. Beginning at the smallest scale, the project examines what kinds of conditions are best suited for connecting people to one another within the site itself in terms of circulation networks, outdoor public spaces, civic uses, and the relationships of buildings and blocks. On a larger scale, the project explores methods for creating connections between the site and the wider community, both locally and regionally, through the integration of trail systems, land uses, and road networks. It also examines the principles for designing a mixed-use component intended to draw people from a wide geographic area and to serve as a center of activity for residents and visitors alike because of its distinctive qualities. Finally, the project examines principles for creating connections between people and the natural environment through the preservation of existing stream corridors, drainage channels, and woodlands and the restoration of the prairie systems that once characterized the land. Instead of sitting in isolation and addressing only the needs of its own residents while turning its back on adjacent land uses and the wider community, the project utilizes a design that directly engages that community through the full integration of its program elements. Traditional neighborhood design principles are therefore best applied not as a formula but rather as a flexible framework for the design components that define the form of the project. Ultimately the project seeks to achieve its goals and objectives not by simply replicating previous efforts but by developing and applying its own creative design solutions.

Unite: Ames, ISU, student, citizen, + place

Meessmann, Andrew January 1900 (has links)
Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Stephanie A. Rolley / College districts are unique places that often times blend the culture, history, and the future direction of a city. They are places that foster knowledge, interaction, and diversity. A successful college district enables all citizens to help shape a place that is unique amongst other districts throughout the city. They are places where people relax, work, socialize, think, revolt, and reunite. They are, perhaps, the most important districts within college towns. The intent of this project is to completely reinvent a district to be one that all citizens (permanent and student) of Ames, Iowa can utilize throughout the year. Reversing the negative perceptions of Campustown through design and programming will help recreate a district that fosters interaction among students of Iowa State University and the citizens of Ames. Further, the recreation of Campustown will benefit the community in terms of image, economics, environment, and place. Campustown will no longer be perceived as an enclave of substandard student housing, trashy bars, and a district that caters to only one group. It will be a place where people come together to celebrate Ames and ISU and to come together to meet friends and family. To enable a thorough understanding of successful college districts, two case studies were examined in great detail to help understand what makes these places work. A complete site inventory and analysis of Campustown was also conducted to help determine where and what shortcomings are present throughout the site. Several different programming elements have been selected that would be appropriate to locate in the Campustown area. And finally, a complete master plan has been created that will enable Campustown to function properly long into the future for every citizen of Ames.
