      Pennington, Georgia; College of Architecture, Planning and Landscape Architecture; Sanderford, Drew; Iuliano, Joey (The University of Arizona., 2019-05-03)
      This research paper aims to examine the food insecurity in Tucson, Arizona and how the use of surplus food distribution markets could be a factor in relieving some of that insecurity. The resources that will be included in this study will be community gardens, farmers markets, and Market on the Move (MOM)/Produce on Wheels Without Waste (POWWOW) projects. After surveying 140 users of MOM/POWWOW, there was no clear demographic of the users. Additionally, less than 10% of the markets were located in food deserts, which emphasizes that there is room to expand markets to these areas to serve vulnerable populations.

      Monshizadeh, Iman; College of Architecture, Planning and Landscape Architecture; Moeller, Colby; Iuliano, Joey (The University of Arizona., 2019-05-01)
      This study set out to find the benefit of high efficiency window retrofits to a medium income Arizona home and specifically how these retrofits impact energy use and cost. To simulate these retrofits an energy modeling software (Energy-10) was used to create a base case home that mirrored the actual home in both design and efficiency. The software was used to create 3 different iterations that only upgraded the windows of the home, each iteration serving as a simulation of a retrofit to the base case home. Energy-10 then generated reports and data that were used to show the benefits, shortcomings, and cost of each iteration
    • WALKABILITY IN TUCSON: AN OVERVIEW OF CURRENT TRENDS AND GROWTH POTENTIAL

      Iuliano, Joseph; Abou-Zeid, Gabriella; College of Architecture, Planning and Landscape Architecture; Currans, Kristina; Livingston, Margaret (The University of Arizona., 2019-05)
      In the United States, the transportation sector was responsible for 28% of 2016 GHG emissions—the largest contribution of any industry (U.S. EPA, 2018). To reduce dependence on fossil fuels and mitigate their effects, active modes of transportation, like walking, need be planned for. This study provides an overview of walking in Tucson, AZ and subsequent guidance for future development through a) an assessment of walk-mode splits, b) a survey on residential preferences for walking, and c) a built environment case study analysis. It found that walking constituted 11% of all trips, compared to motorized vehicles, which accounted for more than 80% of all trips. Percentage of respondent walk and car trips varied significantly by income and trip purpose. Both Tucson residents and existing literature identified destination proximity as the most important built environment factor considered in deciding to walk. A complete streets project that incorporated many built environment features found to improve walkability (e.g., street connectivity, accessibility, walking infrastructure) but failed to account for destination proximity had little impact of walking behavior. To better promote walkability in Tucson, emphasis on coordination between transportation and land use planning and connection of walkability to social and cultural values is necessary.
    • The Negative Impacts of Solar Power

      Wang, Lujia; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey (The University of Arizona., 2019-05)
      With the urban development, more and more environment problems are showing in people’s life. The air pollution causes human health problem and the global warming impact the rise of sea level. To solve the environment problems and reduce the negative effect of environment to the future generation, people start to protect environment and one of the method is using renewable energy. Solar energy is the more popular renewable energy that people use to save energy, because it was clean and the solar resources is abundant. The electricity that transfer from solar energy can improve the energy efficiency use. However, the solar energy is zero pollution and completely clean for several reasons. The following content will discuss the negative impacts of solar power and the strategy to improve the solar energy use.
    • A Comparison Between Chinese Construction and U.S. Construction: From a Sustainability Angle

      Iuliano, Joseph; Wang, Katherine; College of Architecture, Planning and Landscape Architecture; Zhang, Lingling; Iuliano, Joseph (The University of Arizona., 2019-05)
      This paper will be examining the cause of some problems in the Chinese building industry in comparison to the American construction industry from a sustainability standpoint. The differences between the Chinese and American Construction industries are affected by many factors. As a fast-growing economy, China is experiencing rapid growth in its construction industry. Growth leads to prosperity but also sometimes expose problems.
    • Hot Water: Sustainable production and residential applications

      Iuliano, Joey; Lopez, David; College of Architecture, Planning and Landscape Architecture; Moeller, Colby; Iuliano, Joey (The University of Arizona., 2019-05)
      The purpose of the study is to identify how the energy of the sun can be harnessed to heat water in a residential setting. Solar thermal water heaters are used extensively throughout the world to provide a carbon dioxide free solution to an energy rich process. The negative impact of energy production to the health and environment disproportionately affects minorities and working poor. The question of how free sunlight can be used to heat water, reduce energy consumption, and energy insecurity was explored. Greece was used as a case study to determine what the possible implications could be to a town like Tucson, Arizona. Energy production in America by fossil fuels was also looked at geographically to determine where the highest potential, for the most people existed. The study found high incidences of poverty and extreme poverty close to pollution emitting power plants. The study also shows that there is high potential for transition from traditional water heating methods to solar thermal heated water in highly populated areas throughout the American southwest.
    • LEED Needs to Reevaluate Demolition to Stay Relevant

      Kramer, Sean; Holliday, Tyler; College of Architecture, Planning and Landscape Architecture; Almanza, Gabi; Iuliano, Joseph (The University of Arizona., 2019-05)
      The LEED accreditation process is recognized as the benchmark for ranking sustainable buildings in the United States. LEED certification provides building owners and operators with the tools they need to have an actionable and quantifiable effect on their site’s environmental impact (GenFlex Roofing Systems). By promoting a whole-building approach to sustainability, LEED recognizes performance in site planning, site development, water efficiency, energy efficiency, building materials, waste reduction/division, indoor air quality, and attention to regional concerns (GenFlex Roofing Systems).
    • Learning for the Future: Education for Sustainable Development

      Rice, Jenny; College of Architecture, Planning and Landscape Architecture; Herrera, Yvette; Iuliano, Joseph (The University of Arizona., 2019-05)
      This capstone outlines the climate crisis that is currently perpetuated by the burning of fossil fuels. It addresses the need for Education for Sustainable Development (ESD) within established curricula in a traditional and non-traditional school setting. Observations through multiple interviews (N=9) and online surveys (N=54) of University of Arizona students suggest that sustainability concepts in the primary and secondary schools need improvement. Systemic hindrances such as a heavy focus on standardized testing and lack of access to school gardens prevent the mainstreaming of ESD into the regular curriculum. Schools generally associate ESD with outdoor or environmental activities and limit the scope of lesson plans with science as the main subject to connect with. Sustainability is an interdisciplinary concept that can be addressed through nearly all subjects. Continued denial of climate science while politicizing ESD is preventing progressive action toward minimizing the negative effects of climate change. ESD, when thoroughly integrated into the education system could strengthen the opposition to policymakers who insist upon continued subsidies of fossil fuels.
    • Creating Sustainable Spaces: A School Garden Case Study

      Iuliano, Joseph; Howell, Jacqueline Ariel; College of Architecture, Planning and Landscape Architecture; Marston, Sallie; Livingston, Margaret (The University of Arizona., 2019-05)
      The purpose of this study was to identify elements of school gardens that promote well-being in students. Many schools are starting school garden programs around the country, and while it is common knowledge that gardens can promote well-being, the causal relationships are not well understood. To better understand what makes school gardens good for students, I spent 4 months working as a garden intern at Manzo Elementary where I observed students and interviewed teachers and other garden interns. This paper also contains a thorough review of available literature that connects human well-being and green spaces. This research found that students appear to be feel a strong connection to their school garden and a sense of ownership of it, and that kids are more excited to use these spaces than other spaces in their schools. These factors appear to promote well-being in Manzo Elementary students by increasing students’ enthusiasm for learning and teaching responsibility.

    • A Study of Electrochromic Glass Applied to CAPLA East’s Northern Façade

      Kelly-Jones, Alec; College of Architecture, Planning and Landscape Architecture; Chalfoun, Nader; Iuliano, Joey (The University of Arizona., 2019-04)
      I conducted a cost-benefit analysis on electrochromic film as an energy saving strategy at the University of Arizona’s College of Architecture, Planning & Landscape Architecture East building. Using eQUEST, I created a whole building energy model to simulate electrochromic film on its Northern façade, quantifying the effect on the building’s heating and cooling demands. The film proved to be so effective, saving 19,220kWh a year, that I designed a second iteration with only half of the northern façade retrofitted. This also proved to be a viable energy saving strategy, reducing consumption by 15,090kWh.
    • Identification of Historic Streetscape Features in Three of Tucson's National Register of Historic Places Districts: Barrio Anita, Winterhaven, and Colonia Solana

      Berger, Wyatt; College of Architecture, Planning and Landscape Architecture; Erickson, Helen; Iuliano, Joey (The University of Arizona., 2019-04)
      Historic preservation is often at odds with new development in the United States because of individuals’ and developers’ belief that “newer is better.” Part of the historic built environment includes historic streetscapes features such as sidewalks, utilities, heritage trees, fences and walls, driveways, and views and vistas. While Tucson, Arizona does have support for preservation via Certified Local Governments, zoning ordinances, and community involvement, there is no programming for historic streetscape preservation. With the destruction of historic buildings and other features to make way for wider streets and large-scale housing and office spaces, cultural resources are threatened. Though new development may be good in creating a stronger infrastructure, historic preservation supports the idea of a “sense of place” as well as sustainable benefits most individuals fail to see. This study aims to analyze the importance of historic streetscapes in three of Tucson’s National Register of Historic Places districts by using personal observations, community participation, and digital mapping techniques.
    • 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 Importance of Sustainable Animal Education: A Study in Participation in Arizona-Sonora Desert Museum Desert Tortoise Program

      Kramer, Sean; Lorenz, Emily; College of Architecture, Planning and Landscape Architecture; Dimond, Kirk; Iuliano, Joseph (The University of Arizona., 2019-04)
      The Arizona-Sonora Desert Museum (ASDM) has a Tortoise Adoption Program to help rehome the surplus of desert tortoises to Sonora Desert locals. Also, it has been proven that there are many benefits to early childhood learning and adopting practices at a young age. There could be many benefits to integrating a younger population into the Tortoise Adoption Program (TAP) at the Arizona-Sonora Desert Museum
    • Sustainable Building Industry in Phoenix, Arizona

      Kramer-Lazar, Sean; Kilpatrick, Timothy; College of Architecture, Planning and Landscape Architecture; Pivo, Gary; Iuliano, Joseph (The University of Arizona., 2019-04)
      This article serves as a brief analysis of the sustainable building industry in Phoenix, Arizona. The process begins by illustrating the need for this type of development by discussing the benefits, the financial feasibility, and the overall need for these types of buildings in the larger context of our world. Phoenix, Arizona’s market, environment, and population are then briefly introduced and discussed. The project incorporates both qualitative and quantitative components; including case studies of a diverse set of green buildings in Phoenix from several different asset classes, as well as in-depth discussions with industry professionals who played roles in these projects. The study aims to discern what works with regards to sustainable building in Phoenix and what does not. Quantitative data is used to understand building features, compare resulting energy savings, discuss the economics of each of the projects, and justify their overall success from a financial perspective. Qualitative data is used to understand and discuss the motivations of each of these projects as well as any additional information that industry professionals bring up. The understanding of the success of these projects is meant to inspire future developers in Phoenix, Arizona, and perhaps other markets, to pursue sustainable building as a means of producing higher quality, more prosperous development projects.
    • BLOOMING & DYING: AGAVE WITHIN TUCSON’S BUILT ENVIRONMENT

      Livingston, Margaret; McGuire, Grace; College of Architecture, Planning and Landscape Architecture; Smith, Steve; Iuliano, Joey (The University of Arizona., 2019-04)
      This study examines one plant species in order to reveal the historical, biological, and social attachments the plant brings to the public and private landscapes in the city of Tucson, Arizona. The life cycle history, cultural attachment, and biological characteristics of the Agave genus are evaluated in terms the relationship between a native, Sonoran Desert adapted species and its use within the urban matrix. The succulent, rosette form is a characteristic that makes the agave species distinct from all other desert plants. Six particular agave species are mentioned within this writing, and are connected to the Tucson area’s cultural history, and current application of agave as a landscaping material. Agaves symbolize a rich history of human utilization and reliance, especially in the cultures of central/northern Mexico. As the industry within the U.S. for mescal products grows, agave on the landscape become distinctly agriculture based. The practices of wild harvesting agave for distillation and not allowing cultivated agaves to bloom impacts the ecosystem functions of northern Sonora, Mexico, and the southwestern United States, and severely limits the populations of wild agaves. It is estimated that in the coming years it will be almost impossible to find certain populations of wild agaves.
    • 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.
    • Sustainable Climate Design

      Bean, Jonathan; Lenon, Traci; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey (The University of Arizona., 2018-12-18)
      Sustainable climate design is one that is sensitive to the environment, energy consumption, human thermal comfort, and health & wellbeing. Several tools are used including a psychometric chart, sun dial diagrams, and 3D modeling to make design decisions. A design in Green Bay, WI a cold & humid climate, is analyzed to find sustainable design strategies that achieve this goal.
    • Streetcar Track Risk to Cyclists: Education as a Solution

      Adkins, Arlie; Friberg-Landon, Alexandria; College of Architecture, Planning and Landscape Architecture; Iuliano, Joseph (The University of Arizona., 2018-12-14)
      The study evaluates bike safety education as a solution to bike crashes involving Tucson’s Sun Link Streetcar Tracks. Bike crashes on streetcar tracks present a problem for public safety that is complex and unique. This study measures the effect of bike safety education on bike crash rates on the streetcar tracks. A survey was used to measure bike crashes on the streetcar tracks before and after the treatment was given. The first survey measured the number of bike crashes on the tracks in the past 8 weeks and randomly divided the treatment and control groups. The control group received no education. The treatment group watched a 3 minute bike safety video. After 6 weeks, a second survey measured the number of crashes on the streetcar tracks in both groups since. The crash rates were compared before and after the treatment and between the groups. The p-value of change in crash rate between the treatment and control groups is .2209. This means that there was not a significant difference between the two groups. The change in crash rates is not likely a result of the educational video. Part of the study is an index to measure the knowledge level of participants about bike safety, specifically as it relates to the streetcar. The index used answers to questions in my survey about experience, risk perception, formal education experience, and how to cross the tracks. This index could be helpful in future studies about bike safety education. While no relationship was found between education and bike crashes on the streetcar tracks in this study, future studies could find something else. If future studies find education effective, then treating the problem might mean a slight shift in bike safety education resources to be more oriented towards the streetcar tracks. If education is not effective, then we need our infrastructure and design standards to change to prioritize safety.
    • ROUTE REPAIR: DESIGN CHANGES TO IMPROVE SAFETY AT MOUNTAIN AVENUE AND HELEN STREET

      Fitzpatrick, Quinton; College of Architecture, Planning and Landscape Architecture; Adkins, Arlie; Iuliano, Joey; Livingston, Margaret (The University of Arizona., 2018-12)
      The intersection of Mountain Avenue and Helen Street in the city of Tucson, Arizona, lies at the end of a high use pedestrian and cyclist corridor. The intersection is located near the University of Arizona and is vital in facilitating walking and cycling connections to the university as well as the greater surrounding areas, including downtown Tucson. The intersection is currently unsafe and inefficient as a result of both design and location. This Thesis attempts to analyze and provide recommendations for potential design changes that would increase both vehicle levels of service and safety for all road users. A case study of successful cities and nationally recommended best practice design strategies was conducted to determine what features and infrastructure could be implemented to improve the intersection. It was found that safety infrastructure at intersections and connectivity between safe intersections were among the best practices for improved bicyclist and pedestrian safety. An application of these designs to the study intersection was explored with several alternatives offered. The application of left turn and straight through restrictions for automobiles proved the most promising design change. A significant increase in the level of service of the intersection was observed along with a 66% decrease in the number of conflict points at the intersection, a proxy for intersection safety. In conclusion, it is recommended that turning restrictions be implemented at this intersection to improve walking and cycling safety and connectivity in the greater university region of the city of Tucson.
