• ABSOLUTE STREET, a new type of streetscape for future high-density urbanism

      Livingston, Margaret; An, Tai (The University of Arizona., 2019)
      During the past decades, conflicts between the natural ecosystems and the need for urban development has led to a loss of connection to green spaces in urban cores. The Park Avenue in New York represents a highly-developed central business district with limited connections to green space. Currently the pedestrian space in Park Avenue exists as only a 16-foot-wide sidewalk. With limited areas for green space, people generally move from one destination to another with a highly-straightforward purpose. The median in this area could represent a space associated with activities that would capture interest for those moving through the space. Urbanism often drives the downtown area into an antipedestrian place where structures and automobiles occupy 90% of the surface. People are active “in the cracks” of those components, where population and parking problems are often not addressed. This project focused on a modular design on Park Avenue to study different possibilities that attempt to highlight how green space and inhabitants coexist with the development of the city. Additionally, it presents a solution to replace a simple function area with one that is more multi-functional.
    • Accessibility for persons with mobility impairments in Sabino Canyon Recreation Area's Upper Canyon

      Havens, William H.; Steward, Shirley Kathleen, 1949- (The University of Arizona., 1992)
      This thesis discusses accessibility issues for persons with mobility restrictions visiting Sabino Canyon Recreation Area's Upper Canyon near Tucson, Arizona. A shuttle bus from the Visitor Center area provides the only motorized access into the Canyon interior. Designated shuttle stop areas are inaccessible, preventing some individuals with mobility problems from extending their time in the natural setting. The purpose of this study was to investigate physical inaccessibility at the shuttle stops and provide design recommendations to improve access appropriate to the natural setting, using proposed guidelines which are being considered by the USDA Forest Service, Sabino's managing agency, for its outdoor recreation areas. The methods used were an evaluation of each shuttle stop area and application of the proposed guidelines to assign accessibility accommodation levels to each shuttle stop. Recommended modifications within each level are given. Conceptual plans for two shuttle stop areas and detailed drawings for facility accessibility are provided. A review of literature on human preferences and psychological benefits associated with natural environments, the impacts of physical disabilities, and accessibility legislation and standards is included.

    • Adapting a Green Roof in Tucson, Arizona

      Iuliano, Joseph; Cutter, Shea; College of Architecture, Planning and Landscape Architecture; Gilette, Heather (The University of Arizona., 2019-04)
      Buildings that implement a green roof on their rooftop generate economic and environmental benefits throughout its lifetime than a conventional roof cannot. A space that would normally not be utilized is transformed to benefit the building's operations and occupants. However, there is little research on green roof applications in hot and arid urban climates. This paper is based on an extensive literature review on the current capabilities of green roofs to generate enough savings and benefits to a building to combat the initial installation fee. Finding the Net Present Value (NPV) of the cost of installation and benefits of a green roof is used to create a benefit analysis. In order for more research to be done in hot and air urban green roofs there needs to be a market for it. This research paper uses a benefit analysis to break down the economic feasibility of the investment based on the savings and benefits received after construction. The site location used to generate the data for this proposal is on the College of Architecture, Planning, and Landscape East building (CAPLA East). The analysis demonstrated that a 5,000 square foot extensive green roof would be economically feasible based off of the NPV of the savings and benefits created after construction. Furthermore, the research identified that the plants best fit for the weather conditions of a green roof are the drought-resistant plants found in the Sonoran Desert that Tucson is a part of.
    • Adaptive Reuse as a Sustainable Solution

      Breckenridge, Lauren; College of Architecture, Planning and Landscape Architecture; Daughtrey, Cannon (The University of Arizona., 2018-12)
      The scope of the research if focusing on how adaptive reuse of historic buildings satisfies the three pillars of sustainability. The implementation of adaptive reuse will reduce environmental impact, provide a place for communities to learn and interact with, and bring money into the local economy. The methodology for the study included an online survey, case studies, and literature reviews. This allowed the research to be unbiased and to obtain current research on the topic to figure out if there is a lack of knowledge on the topic. Case studies offer real-world examples of adaptive reuse in and their payoffs. The literature reviews provide information on the concepts and strategies that are involved with adaptive reuse. An online survey was conducted to grasp the general public’s knowledge of the topic. The purpose of researching adaptive reuse in historic buildings is to persuade people to restore a property for a new use rather than constructing a new building. This practice will be able to fulfill social, environmental, and economic sustainability in communities. The findings towards the research topic implied that more research and implementation of adaptive reuse in historic buildings need to be utilized to show the benefits as a sustainable solution.
    • Adaptive Reuse: A Proper Way for Chinese Architectural Preservation

      Lin, Xiaojun; Green, Ellery; Green, Ellery; Matter, Fred S.; Yoklic, Martin (The University of Arizona., 1995)
      For many developing countries, a major problem is the challenge of preserving cultural integrity in the face of modernization. On the one hand, these countries have a common goal to develop their national economy and improve standards of living for their people. On the other hand, they need to protect the integrity of the indigenous culture during the process of development which itself often brings in external influences and new lifestyles. Modernization and development require technologies, resources and materials which come from trade and an open economical policy strongly influenced by western culture. Modern western civilization strongly influences the societies, economics and social relations in many developing countries, and can cause major changes in the way of life. As a developing country, China is facing that great challenge today: Is it possible to pursue modernization and at the same time maintain the integrity of culture? This challenge confronts not only scholars and policy makers, but developers, architects and the residents of the communities themselves.
    • Adaptive Use: A Guide Towards Sustainable Regeneration

      Cardenas, Alexis; College of Architecture, Planning and Landscape Architecture; Chalfoun, Nader V; Iuliano, Joseph E (The University of Arizona., 2017-05-12)
      Sprawling development continues to be the common method of creating a built environment that facilitates the growing proportion of people living in urban settings. Inadvertently, this brings forth many social, economic, and environmental adversities that cause for a redirection of development. Adaptive use is an architectural conservation strategy takes an existing building and rehabilitates it so that it can serve a new use. The rehabilitation process improves the performance of an existing building while suppressing many of the negative effects associated with the sprawling development and new construction. The purpose of this report is to draw upon successful adaptive use practices to create an outline of methods can be applied to future projects of a similar nature.
    • Addressing Sustainable Management of Natural Resource Use: Coltan

      Makabu, Moïse; College of Architecture, Planning and Landscape Architecture; Iuliano, Joseph (The University of Arizona., 2018)
      The Democratic Republic of Congo (D.R.C.) is home of Tin, Gold and Coltan which is extracted from tantalum (Ta) and is a key mineral in the production of cellular devices, laptops, aviation components and other electronics. With the mining practices having an effect on land, wildlife & biodiversity, government officials and industry leaders worldwide must adopt sustainable approaches and socially responsible policies and report on their implementations to assess impacts. The movement towards sustainable management of natural resources in the D.R.C. would require proposing organisations such as the United Nations Global Compact to take initiatives in aiming to encourage D.R.C.’s mining industries and coltan-using industries worldwide to adopt sustainable and socially responsible policies.
    • Adopting Geothermal Heat Pumps

      Camarena, Paul; College of Architecture, Planning and Landscape Architecture; Iuliano, Joseph (The University of Arizona., 2019-04)
      Global climate change is a major problem we are facing. Thirty percent of the global greenhouse gas emissions are being produced by electricity production, while six percent is produced by buildings. Climate change is happening now. This capstone examines the way in which the use of the earth’s natural properties can help combat climate change through the use of Geothermal heat pumps in the residential sector.
    • The Age of Net Zero

      Le, Joseph; College of Architecture, Planning and Landscape Architecture; Magdy, Omar (The University of Arizona., 2015)
      Captivated by the sustainable design principles and concepts, this study explores the definition of what is net zero and how has this concept become the new standard in today’s society. By analyzing several case studies, the qualitative and quantitative data will give insight into developing the ideal performance of green and sustainable buildings in relation to a net zero energy focus. The idea of sustainable design began as an economic tool to reduce high energy consumption in order to minimize cost in building construction. Nonetheless, this practice has evolved further into elevating the social and environmental, as well as economic standards of building design in the twenty-first century.

    • Alternative Sustainable Design within an Established Structure

      Cooney, Katie; College of Architecture, Planning and Landscape Architecture; Griffiths, Jason; Keith, Ladd; Iuliano, Joey (The University of Arizona., 2015-05-08)
      This thesis seeks to develop an alternative sustainable design for the CareLink of Jackson medical facility. Through a thorough analysis of the structure, community, environment, and user interaction within and around the building, a complete understanding of the facility's needs, successes and failures were composed. Based on this analysis, an alternative design was then proposed of which incorporates improvements to the building's green space, solar utilization, and social integration. This final design analysis and recommendation can be used to inform similar redevelopment of established structures in the benefits of sustainable integration within architecture.
    • AN ALTERNATIVE TO TRADITIONAL SPRAWL DEVELOPMENT: A Look at Mixed-use Developments in Tucson, Arizona

      Freeman, Nicole; College of Architecture, Planning and Landscape Architecture; Bekat, Camila; Iuliano, Joesph (The University of Arizona., 2016)
      Rapid urbanization has profoundly reshaped societies, economies, and the natural environment. Urban populations currently sit around 80% and 40% for developed and developing countries respectively with cities accounting for nearly all future population growth. The impacts of urbanization are vast lending to low density areas, traffic congestion, automobile reliance, pollution, and biodiversity loss. Sustainable development is essential to maintaining the integrity of the world with current and future anticipated levels of urbanization. Mixed-use developments or those which combine three or more integrated revenue producing uses are a form of sustainable development which can help mitigate the negative effects of urbanization. Benefits of mixed-use include pedestrian and bicycle friendly areas, place-making, increased revenue, and reduced automobile reliance and pollution. This research attempts to determine the most successful form of mixed-use development in downtown Tucson, Arizona. This study boundary was chosen because downtown Tucson is in a state of revitalization and it is important to analyze how developers and the City of Tucson are making use of land. For the purpose of this research a case study analysis was performed on three mixed-use developments, the Cadence at Congress Street and 4th Avenue, One East Broadway at Broadway Boulevard and Stone Avenue, and the Mercado San Agustin at Congress Avenue and Avenida del Convento. Each development was examined and rated based on economic, social, and environmental success. All three developments scored fairly similarly but the Cadence scored the highest with low operating costs, the creation of a high volume jobs, and a location near transit and pedestrian and bicycle friendly areas.
    • Amphitheater High School’s Outdoor Classroom: A Study in the Application of Design

      Rioux, Andre; College of Architecture, Planning and Landscape Architecture; Livingston, Margaret Phd; Iuliano, Joey (The University of Arizona., 2016-05-06)
      There has been a nationwide movement which has promoted urban agriculture. The locale, seasonality, and methods of cultivation, have all entered the spotlight of public consciousness. While farmer’s markets, and co-ops may sometimes have limited accessibility with respect to cost another community gardens are branch of the urban agriculture movement which are highly accessible. The surge in popularity of community gardens came with the 2008 market crash, which created many foreclosures, and accordingly vacant lots. Where vacant lots are reclaimed by citizens, they create a sense of ownership within a community, they become physical manifestations of neighborhood rally cries, elbows rub, and community connections are made. With a relatively small amount of initial input, and continued care, there are tangible outputs, and literal fruits of labor. The popularity of these gardens extends to schools, and a whole branch of pedagogy which emphasizes place based learning. The benefits to these schools is tremendous; students are offered the opportunity to be academically engaged in a space other than the traditional classroom. Community gardens show the potential to create value from little input. With the benefit of a structured design process, there is potential to make school gardens learning space, in addition to growing space. The intent of this study is to explore the value created for these spaces by a formalized design process.
    • AN ANALYSIS OF AFFORDABLE HOUSING SUPPLY & DEMAND IN TUCSON, ARIZONA

      Wong, Hannah; College of Architecture, Planning and Landscape Architecture; Iuliano, Joseph (The University of Arizona., 2016-05-06)
      Housing is a basic necessity that should be available to everyone at every income level. The danger of becoming a cost burdened household (household spending 30% or more of the area median income on housing costs) is high for all income levels. However, extremely low income households are one of the demographics that are the most susceptible because they have limited affordable housing units available to them at their income level. Addressing this gap between income and affordability in housing is something that is particularly important to ensure that these extremely low income households have enough money for not only housing but other basic necessities such as food. Various incentives and programs are out there to try and provide these extremely low income households with the affordable housing they need however, it does not always happen in the areas that are the most in need. This study will examine the supply and demand of affordable housing for extremely low income households in Tucson, Arizona. The research identifies areas that have clusters of extremely low income households that are cost burdened as well as the affordable housing units available to them. Based on this information funding sources are discussed and recommendations regarding how to implement more affordable housing units in the areas of need are discussed.
    • Analysis of Best Management Practices for Addressing Urban Stormwater Runoff

      Maass, Amanda; College of Architecture, Planning and Landscape Architecture; Perkl, Ryan; Iuliano, Joey (The University of Arizona., 2016)
      During Tucson rainstorms, many roads and neighborhoods experience high levels of flooding on the city’s street networks. This phenomenon creates unsafe road conditions, damage to the road infrastructure, and excessive urban stormwater runoff that is potentially polluted. The vast quantities of impervious surfaces in the urban landscape impede the rainwater’s ability to infiltrate the ground, thus resulting in increased volumes of runoff during a rainstorm. Stormwater management is used by municipalities and communities to address the previously mentioned adverse impacts of stormwater runoff. Various techniques and strategies used in stormwater management include, low impact development (LID), green infrastructure, and better site design (BSD) strategies implemented during design stages to reduce stormwater runoff levels. In addition, local governments can establish stormwater utilities and policies in order to help address and better manage the issue of stormwater runoff within urban areas. The primary research questions of this study will include: What are the most effective best management practices and techniques to address urban runoff? What combination of best management practices and government policies will be the more effective in addressing Tucson’s urban runoff problem? Accordingly, this study will examine a variety of policies and techniques to address stormwater runoff, and then, based on this information, provide a suggestion of the best practices and techniques that may be feasible for implementation in Tucson.
