  • Landscape Disconnect: A Study of the City of Tucson's Landscapes in the 20th Century

    Apanovich, Nataliya; Martin, Ashley; College of Architecture, Planning and Landscape Architecture; Apanovich, Nataliya; Apanovich, Nataliya (The University of Arizona., 2024-05)
    The City of Tucson, Arizona, lies within the Sonoran Desert, yet a large portion of landscapes don’t reflect this ecosystem. The 20th Century brought about this disconnect, which is reflected in how we develop our urban greens spaces. Through the investigation of Tucson’s history with urban green spaces, we find that modern technology mixed with unrealistic ideals fueled an increase in exotic plant species use in commercial and residential landscaping. Through city-wide education programs, increased water use rates, and the implementation of native plant focused ordinances, the city was able mend some past mistakes in developing. Today, there is work we can be doing to improve our efforts, with 83% of residents from a local survey requesting more information on the benefits of Arizona native plants.

    Apanovich, Nataliya; Gammariello, Bethany; College of Architecture, Planning and Landscape Architecture; Apanovich, Nataliya (The University of Arizona., 2024-05)
    Waste diversion at higher education institutions in the U.S. remains a growing issue. Recyclable materials that enter landfills have negative environmental impacts as well as expensive landfill service costs for universities. The University of Arizona partnered with a zero waste consulting firm to identify gaps in the current waste management operations by engaging with department head stakeholders, but did not include any form of student engagement. This research targeted the student body to identify ways to improve recycling and zero waste efforts on and around the University of Arizona campus. The research included surveying students about recycling and observations of recycling sites selected by the students. Recommendations were made following the observations and included increasing the amount of recycling bins, ensuring that recycling bins are adjacent to trash cans, standardizing the appearance of recycling bins with the help of labeling, color, and informative graphics, and finally increasing educational opportunities about recycling and zero waste efforts for students at the University of Arizona. Further research should include conducting more student surveys and engaging with the University of Arizona’s Office of Sustainability coordinators in charge of the zero waste campus program in order to identify further gaps and improvements in waste management operations.
  • Why the Sidewalk Ends: Analysis of Sidewalk Infrastructure in Tucson, Arizona

    Schrauth, Anna; College of Architecture, Planning and Landscape Architecture; Apanovich, Nataliya (The University of Arizona., 2024-05)
    Inequitable sidewalk infrastructure perpetuates social inequalities. Furthermore, good sidewalk infrastructure has many health, social, and environmental benefits. To study the inequitable sidewalk infrastructure in Tucson, I did a case study analysis of two neighborhoods of different socio-economic status. The neighborhood with higher income levels had more and better sidewalks. I conducted interviews with neighborhood representatives and the city of Tucson professionals to understand why this was. I found that the main issues with current sidewalk development were that the funding sources are problematic and the responsibility for sidewalk development often ended up on the property owners or developers. To remedy these issues, I propose a new funding source, a development tax, and a city-run program to target areas in the greatest need of sidewalk infrastructure.

  • Navigating Green Building Certification, Sustainability, and Public Perception: Identifying and Understanding Barriers to Widespread Adoption of Green Building Practices in Smaller Municipalities

    Thomas, Deirdre; College of Architecture, Planning and Landscape Architecture; Bernal, Sandra; Apanovich, Nataliya; Bernal, Sandra; Wong, Kenny (The University of Arizona., 2024-05)
    Despite the growing prevalence of green building (GB) practices in larger urban centers, as highlighted by existing research, smaller municipalities face significant challenges in adopting these practices due to economic, social, and regulatory barriers. Using a mixed-methods approach, this study integrates a systematic literature review (SLR) with a 33-participant survey and nine follow-up interviews to gather qualitative and quantitative insights into the barriers and motivators affecting GB adoption in smaller municipalities. The findings identify that the main barriers are actual and perceived high costs, limited public awareness of certification programs, and inadequate municipal support. Key motivators for adopting GB practices were financial incentives and targeted public education to promote increased GB adoption. This study highlights the importance of adapting policy and community engagement approaches to bridge the knowledge gap, align stakeholder interests with sustainable objectives, and foster enhanced community sustainability, seeking to motivate a more widespread integration and acceptance of green building practices at the municipal level.
  • Determining Insulation Materials for Low-Income People in Rural Areas with an Innovative Technology

    Shorty, Damon; College of Architecture, Planning and Landscape Architecture; Bernal, Sandra; Apanovich, Nataliya; Bernal, Sandra; Wong, Kenny (The University of Arizona., 2024-05)
    Many rural low-income communities throughout the United States have families that are forced to live in houses that are poorly constructed, which can create a variety of health issues, reduce the quality of life, and increase energy burdens. Rural low-income people often have difficulties accessing home energy improvements, expert people, and/or technology. There are many technologies and techniques for testing the performance of insulation materials. This study investigates innovative technology to test the performance of various insulation materials that include fiberglass, mineral wool, expanded polystyrene, cellulose, and four developed composites. Testing was performed for one hour using innovative technology to measure the OSB sheathing/insulation material surface temperatures, chamber air temperatures, and relative humidity every five minutes. The performance data collected were analyzed after all insulation materials were individually tested. The innovative technology could perform consistent tests on insulation materials to show the user materials that could promote a stable interior environment. Insulation materials composed of cellulose outperformed other materials and can promote a circular economy in the targeted communities. Cellulose can resist a high amount of heat transfer, be sourced locally, is organic, and recyclable. Finding solutions to address the high energy usage of buildings from being insufficiently (or non) insulated is going to be a challenge in the years to come as climate change becomes more prevalent.
  • Closing the Loop: Harnessing Renewable Natural Gas from Agricultural Waste for Sustainable Farming and Environment

    Bobst, Johanna (Hanna); College of Architecture, Planning and Landscape Architecture; Bernal, Sandra; Apanovich, Nataliya; Wong, Kenny (The University of Arizona., 2024-05)
    Unlocking the transformative potential of Renewable Natural Gas (RNG) from agricultural waste holds the key to addressing environmental challenges while revolutionizing sustainability in farming. Agriculture plays a pivotal role in global food production but is also a significant contributor to environmental pollution through greenhouse gas emissions and improper waste management. Livestock farming generates substantial amounts of organic waste, including manure, which releases methane—a potent greenhouse gas—into the atmosphere. The overarching efforts of previous research on this issue derive from environmental agencies outside of the agricultural and RNG spaces, which created a binary approach and were thus unable to assess the full scope of the issues and potential solutions available. Renewable Natural Gas (RNG) production from agricultural waste provides a favorable solution to alleviate these environmental challenges by repurposing organic waste into a renewable energy source. There are significant benefits to the use of Renewable Natural Gas (RNG) production sourced from agricultural waste, with a focus on livestock manure, as a solution to environmental challenges in agriculture. This research examines the mitigation of greenhouse gas emissions, the utilization of digestate with a focus on a circular economy, potential risks associated with feedstock supply, and the influence of scalability frameworks on RNG implementation. The findings demonstrate the substantial environmental benefits and highlight areas requiring further research and policy development to overcome the limitations and realize the full potential of RNG in agriculture.
  • Helical Piers. What is needed for the successful introduction of helical piers in Guilford County, NC.

    Bernal, Sandra; Beitz, Paul; College of Architecture, Planning and Landscape Architecture (The University of Arizona., 2024-05)
    In the face of a housing shortage and climate crisis, helical piers, a widespread technology used since the mid-1800’s, is a style of foundation that offers higher efficiency than traditional foundation types. This study focuses on why builders continually use traditional foundation building practices that take longer to install, require more skilled labor, and have larger embodied and operational carbon emissions associated with them, than building with helical piers. Currently the use of helical piers in new construction is non-existent in Guilford County, North Carolina. Interviews, a building performance survey, and observations allowed for the collection of data from homeowners, renters, building professionals, and building inspectors to better understand why this building technique has not been introduced. Outcomes are used to inform on the successful introduction of helical piers in Guilford County. The results revealed that most residents are unfamiliar with helical piers, contractors are nervous to try a new building system, and that Building Inspectors are open to more helical pier installations but see becoming a successful foundation system in Guilford County as a challenge. There are successful helical pier installers 100 miles south of Guilford County however, and the conclusion has recommendations on steps that can be taken to have a successful introduction of helical piers in Guilford County.
