  • Redesigning the most vulnerable houses in San Juan de Miraflores, Lima

    Velazco Gomez, Ivanna Yashury; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey (The University of Arizona., 2021-12-16)
    The increase in human settlements has led to the growth of precarious housing without any design involved. Understanding why citizens settle in places with poor construction and poor development in urban planning is key to determining and proposing a design according to their needs and the environment in which they live. Statistics of the people who live in the area on human settlements in Lima’s San Juan de Miraflores district demonstrate the lack of access to basic needs and the unsafe materials used. The sustainable housing project from Llatas Architecture Studio aims to transform developments with the reuse of existing material like corrugated sheets and plywood, and adequate construction systems in a sustainable way. These designs consider the reuse of water, natural ventilation and lighting, efficient basic services, and controlled growth in the future. The various environmental and economic advantages of scaling up this housing model would benefit both the owner and the district toward a more sustainable city.
  • Sustainable Condominium Design in Cieneguilla, Lima - Peru

    Velasco, Sebastian; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Wong, Cristina (The University of Arizona., 2021-11-28)
    In view of the constant and rapid development of the Peruvian capital, Lima, and the excess of consequences and effects the construction sector has into the environment, this capstone consists in the research of possible solutions for this problem that has to be stopped. Thus, it has been analyzed how can how can renewable energies be implemented in Peruvian buildings to make them self-sustainable? Throughout the capstone, the has been a series of steps, first, finding the perfect location to have the correct viability to implementate solar energy as a primary source of power. After identifying the correct location, the project consisted in the development of a sustainable condominium made up by a series of Le Corbusier’s DOM-INO house variation, following sustainable criteria to dispense with the necessity of artificial illumination or air conditioning systems that increase the energy consumption in those buildings.
  • Strategies for Sustainable Housing for Communities in Loreto, Peru

    FÉLIX QUIPUSCO, BÁRBARA BEATRIZ; College of Architecture, Planning and Landscape Architecture; Wong, Cristina; Iuliano, Joey (The University of Arizona., 2021-12-14)
    Illegal logging is a driving factor of forest degradation. Moreover, other leading causes are mining, agriculture, urbanizing the area without planning, and the illegal merchandising of raw material. The damage to the ecosystem and biodiversity affects the city of Iquitos, located in Loreto, Peru; on a larger scale disturbs the environment, the country’s economy, and native communities. A way to address these concerns is through building, design, and planning. This research explored housing in Iquitos, both traditional and contemporary, and proposes a sustainable design solution for a house. It emphasizes two factors of great relevance: a house that meets the standards of care and respects the natural environment, and a house that people can identify with, and serve as a starting point for an optimal life in the community. A conclusion on the analysis of both current projects and vernacular architecture considerations shows the proposed solutions. These solutions are sustainable, and they seek to reduce negative impacts on the environment, specifically those that directly affect the jungle. The proposed design strategies demonstrate how we can adapt contemporary designs with vernacular architecture and use that combination to guide both contributions.
  • Ravaged by floods - Peruvian Amazon - The city of Belen - The Amazonian Venice

    Velis Suárez, Adriana Cecilia; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Wong, Kenny (The University of Arizona., 2021-12-15)
    Through the last few years, the rapidly growing population in the Amazon has stressed inadequate infrastructures that generate problems when floods strike. Each year, river floods assault the region in the summer season, destroying and damaging houses between December and April. As a vulnerable area, Belen needs to be aided by focusing on long-term results, providing community resilience, creating strategies for disaster response, and adapting the river space. Defenses need to be implemented along the river, and the city needs to retreat to avoid constant disasters. These changes can also improve livelihoods since existing conditions are bad and worsen with flooding. This report analyzes different case study projects from South Korea, Singapore and California to gather diverse solutions to this common problem. It considers how these strategies would be applied in the city of Belen and recommend several interventions for flood protection. The use of gabions, agriculture, and additional space for the potential river solutions can be applied in this study area. These can benefit the community by reducing contamination that would be slowed down with flora cleaning systems, mitigating pollution. These strategies can be gathered into a cohesive urban design that implements social spaces, green areas and agriculture, to provide a healthier and risk-free area or the community.
  • Renewable solar energy as the main power source

    Motta, Oscar; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Iuliano, Joey; Wong, Kenny (The University of Arizona., 2021-12-15)
    This research studies renewable solar energy as the primary power source for homes. The research question is based on how could climate change be mitigated by implementing solar renewable energy as the main power source in San Borja’s housing buildings? Homeowners benefit from choosing a sustainable housing building in terms of saving money and helping to reduce the effects of climate change through sustainable solutions and alternatives. Some case studies have shown that San Borja has started leading sustainable housing solutions based on renewable energy, and cost-benefit studies have supported the use of renewable energy. Data collection such as literature reviews, case studies from the study area, and surveys were developed to get accurate information for the research. San Borja is a potential area where renewable solar energy can be implemented in housing buildings due to the studies that have taken place there and the sustainable initiatives it is developing. This could bring Peru a new way to start using more sustainable solutions and alternatives to benefit people and the environment.
  • Sustainable Alternatives to Concrete Applied in South America

    Sosaya, Silvana; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Wong, Kenny (The University of Arizona., 2021-12-15)
    This research explores the feasibility of green materials and technologies in San Juan de Lurigancho (SJL), in Lima, Peru. The district is threatened by pollution caused by city factories, affecting citizens’ health. There is a need to improve the neighborhood’s safety and quality of life, summed up with a positive outlook on building sustainably, expressed by neighbors through surveys and by other authors in Latin America. The research shows how through architecture and alternatives to traditional materials like sustainable concrete and cement, the neighborhood’s quality of life could be improved by constructing buildings from new materials. Doing so would improve the air quality, address seismic concerns, and create a safe space for the community to learn, grow, and develop. An investment is needed for the project to be executed, considering the cost of implementation and the machines to produce the materials. However, it will also rely on the use of local resources, and overall, will improve residents' lives.
  • Restoring the Ucayali River in Pucallpa

    Virhuez Delgado, Pierina Angela; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Wong, Kenny (The University of Arizona., 2021-12-15)
    The Ucayali River presents high levels of pollution due to sanitary problems and the neglect of the river. The project seeks to restore the Ucayali River in the urban area of Pucallpa using green infrastructure and strategies to achieve local approval of the project. Data analyzed supports the need for restoration of the Ucayali River due to high levels of pH and lead in the urban area of Pucallpa. In recent years, there has been a tendency to restore rivers in urban areas. Previous studies have shown that river restoration projects can help residents conserve this natural resource and provide public spaces. In addition, similar case studies were analyzed to assess which design strategies were best for the project. Moreover, inhabitants were surveyed for their opinions of the design proposal. The residents’ opinions supported implementing green infrastructure and other strategies according to their preferences or need. Also, they considered it necessary to restore the Ucayali River in Pucallpa. The strategies that work for Pucallpa are urban and green infrastructure, agriculture spots alongside the riverbank, and flood platforms to protect the city. Finally, Pucallpa can become a greener city due to its location in the Peruvian jungle and its direct connection with the Ucayali River. For this reason, it is vital to carry out an urban regeneration plan and restore the river in the urban area of Pucallpa.
  • Urban Agriculture: A Pathway to Fight Poverty in Comas, Lima

    Chumpitaz, Gabriela; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Wong, Kenny (The University of Arizona., 2021-12-15)
    Comas, a district in Lima, Peru, does not have many green spaces and has some of the highest poverty rates in the region. This research explored ways the community can use vacant parcels that are not correctly used and create a communal garden for the benefit of the community. Other districts provided case studies, such as Villa Maria del Triunfo, where communal gardens have been a success and have created work, generated additional income, and reduced social exclusion by creating a community. This study found that communal gardens are beneficial and can help Comas become a producer of products to benefit the health and wealth of the community by utilizing green spaces effectively.
  • Urban Forestry: The Nexus Between Green Areas and Community in La Molina

    Torreblanca, Rodrigo; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Wong, Kenny (The University of Arizona., 2021-12)
    Peru’s biodiversity suffers from deforestation and lacks urban planning, making management and control an issue. With ecosystems damaged, they fall apart from our innate necessity for sustaining life. Open green spaces benefit humans and animals, which asks how can certain solutions like urban reforestation, agriculture, environmental quality help communities in La Molina to gain more public spaces and profit from their services. This study explores urban forestry, planning and landscaping through case studies, demographics, and surveys to understand what matters to the community. Through this data, I propose a park design that could bring benefits to communities, flora and fauna of the site, and can hopefully be replicated in the future in the district and expanded to the whole country.
  • Postive Effects of a Green City in Lima, Peru: The Implementation of Open Green Areas in San Juan De Lurigancho, Peru

    LOYOLA FERRER, LUZ-BELEN; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Wong, Kenny (The University of Arizona., 2021-12-14)
    The sustainability deficit in social, economic, and environmental aspects is very evident in Peru; however, there are efforts to reduce waste and emissions and increase recycling. Their main goal is to improve the quality of life for residents through open spaces, which help address air pollution, provide natural oxygen, and allow residents to breathe fresh air instead of the smell of the street and loud car noise. The San Juan de Lurigancho district is one region in Peru that lacks green space. Several methods can solve this problem by getting to know former residents from SJL and letting them know about sustainability and its benefits. This research proposes an ideal urban design incorporating open spaces and green infrastructure. By learning from successful cases and seeing the benefits of green infrastructure, policymakers can design successful green spaces in San Juan de Lurigancho, dramatically improving residents’ quality of life.
  • Bringing Quality of Life to Residents of Ica

    Chocano, Joaquin; College of Architecture, Planning and Landscape Architecture; Wong, Kenny; Iuliano, Joey (The University of Arizona., 2021-12-13)
    “Low-quality housing has long plagued the low-income communities in Ica, Peru. However, there may be solutions to this housing crisis in the local vernacular architecture” (Maiztegui, 2021). This case study focuses on the housing needs of citizens of Ica to improve their quality of life. It does so by explaining cross-ventilation and comparing it to other ventilation sources to address the problems Ica faces. As a result, I created a prototype house for the lower-income residents in Ica, utilizing cross-ventilation designs from traditional homes in the area, which is the most effective way to provide comfort to the user inside the house. Cross-ventilation expel the hot air inside the house, bringing fresh air from the outside. It costs $0 and wastes 0% of energy. This prototype house provides most of their basic needs without removing the vernacular architecture. Adopting these design standards could help remedy the housing crisis in Ica, Peru.
  • River Restoration and Urban Revitalization in Los Olivos, Lima - Peru

    Campos, Carla; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Wong, Cristina (The University of Arizona., 2021-12)
    Rapid urbanization, inadequate infrastructure, and climate change place communities such as Los Olivos at risk during cyclical flooding. River floods can disrupt a community by damaging infrastructure, housing, access to potable water and transport. Resilience strategies and river defenses for disaster risk reduction need to be implemented in vulnerable areas. The risk factors related to poor infrastructure and planning, poor waste management, and riverfront development must be addressed. A case study methodology provides means to analyze three successful projects to gather possible solutions from different perspectives and realities. For flood protection, gabions, soft green and blue infrastructure system that protects the riverbed from erosion are sustainable, low impact, and easy to maintain. For revitalization, the key is to increase the quality of life. Finally, regarding urban design, the implementation of green areas and street furnishings improves the quality of space, leading to a more cohesive community. The most appropriate solutions identified are applied in the study area in the Los Olivos district in Lima, Peru.
  • Renewable Energy in conventional vs green buildings

    Wong, Cristina; Arce, Valentina; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Wong, Cristina; Iuliano, Joey; Wong, Cristina (The University of Arizona., 2021-11-28)
    The world’s demographic index is rapidly increasing. Every country’s evolvement is affecting one another, especially the environment and the world. This is not always affected by every single country, since some countries are more advanced in technology and resources than others, but most of the world is depending on high amounts of fossil fuels to self-sustain cities and countries. As such, by now it is well informed that the world is being constantly affected on the actions people aren’t acknowledging, such as living a great lifestyle without the affection and knowledge that the world is coming apart. Global warming and climate change are subjects that have progressively been enduring their importance around the world. The most challenging part of this progression is that it has not been accepted around the world. Some countries are not taking climate change seriously and it the world depends on it. For instance, one of the main branches of pollution and the burning of fossil fuels is construction. The carbon footprint of a building is higher than most consuming activities. According to the United Nations Environment Program (UNEP) ‘Buildings and their construction together account for 36 percent of global energy use and 39 percent of energy related carbon dioxide emissions annually.’ (https://archive.curbed.com/2019/9/19/20874234/buildings-carbon-emissions-climate-change) However, this is being revolutionized in some countries in the world such as Sweden, Denmark, and China, where the majority of buildings are net zero, have already applied certain regulations to their buildings and the way they are designed and built. On the other hand, countries like Peru, Argentina, or Chile have the least number of buildings designed and built to reach the net zero goal. The regulations described above mention the LEED, EDGE, BREAM certifications that are given to certain buildings that achieve certain sustainable goals, and these buildings are mainly designed to be self-sustainable, withdrawing energy from renewable sources such as solar panels, hydropower, wind energy, geothermal energy, and biogas. In addition, Peru is a country that has slowly but surely gotten into the business of sustainable buildings and renewable energy, where companies have now introduced the construction of green buildings running on renewable energy, or simply buildings that are sustainable to a certain degree.
  • Restoration and Revitalization of the San Felipe Residence

    Luperdi, Andre; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Wong, Christina (The University of Arizona., 2021-09-09)
    The rapid urbanization of cities, lack of adequate green infrastructure, and uneven impacts from climate change have put residents of large cities at risk from air pollution. According to WHO, air pollution can cause a variety of adverse health outcomes and increase the risk of respiratory infections, heart disease, stroke, and lung cancer. To improve air quality in cities, it is necessary to apply different strategies to help reduce greenhouse gases such as PM2-5 and PM10 particles. A case study studying projects from different perspectives and realities allowed us to adapt the best practices for new places. The best solutions are applied in the study area, the San Felipe Residence located in Jesus Maria, Lima, Peru. To reduce and protect people from greenhouse gases and particles PM2.5 and PM10, the implementation of green areas on the roofs of existing buildings (called aerial parks) is recommended and designed. These roofs aim to help clean the polluted air, in addition to benefiting the residents. Finally, implementing aerial parks and urban furniture will improve the quality of space, leading to a more connected and communicated community. As for the potential audience of this research project, it is aimed at architects and engineers interested in changing the way the city operates and designing a park that can benefit 28% of the country’s total population.
  • Sustainable Urban Redesign for Teodoro Cardenas Street to Improve Urban Security

    Ponce de Leon, Jesus; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey; Wong, Cristina (The University of Arizona., 2021-12-06)
    Insecurity in Cercado de Lima has been a problem for years. One of its streets, Teodoro Cárdenas, presents a level of insecurity slowing down the area’s development. Potentially, this problem lies in the urban design of the area and may affect the functioning of the street. One solution is to provide the necessary tools to propose a redesign of the roadway to promote urban safety. An analysis of the area found that a large part of the street does not encourage pedestrians to stay, the facades of the buildings have no relationship with the exterior, and the street has no spaces where pedestrians can carry out activities. Contrasted with other areas, lack of spaces for permanence and animation is the main factor in citizen insecurity. This analysis helped develop an urban design proposal that takes advantage of the existing virtues of the street to generate activity in the public thoroughfare. Doing so promotes an urban planning approach more focused on the welfare of pedestrians in the street as the main factor against insecurity.
  • Green Marketing: Patagonia vs. Nike

    Smith, Alec; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey (The University of Arizona., 2021-05-15)
    Green marketing has become more relevant in the last decade. Consumers are more observant and knowledgeable nowadays, with social media playing a significant factor. Corporate responsibility has forced companies to be accountable for their actions. People are starting to be more conscious of the environment, meaning they eat healthier and purchase sustainable products. The consumer has the ultimate choice on what product they want. With a wide variety of products, competition is at an all-time high. Sustainable companies, products, and initiatives have gained popularity because of their environmental benefit. People want to help the environment, especially by purchasing something they need. Patagonia and Nike have realized this and have put in significant work to become more sustainable. Although this is great, people may never know the contribution to environmental sustainability the company made without proper marketing. Green Marketing effectively promotes companies’ sustainable efforts to attract more customers. This case study covers Patagonia’s successful green marketing and how Nike has fallen short of marketing its environmental efforts. Patagonia’s perception is solely focused on sustaining the environment. Nike’s environmental efforts are extensive and detailed but have not been marketed very well. In order to reap the profit potential that environmental initiatives can have on a company, green marketing tactics must be used to advertise it.
  • Recommended Design Strategies for a Sustainable Library Retrofit

    Cowling, Ethan; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey (The University of Arizona., 2021-05)
    Using the third floor of the University of Arizona Main Library as a model, this project aimed to identify energy efficiency measures, design strategies to improve occupant comfort, and modernizing library spaces for current functionality. The project identified eight Energy Conservation Recommendations (ECR's) and fourteen Architectural Improvement Recommendations (AIR's). More strategies are identified over the course of this project; however, the following implementations were determined to be the most pertinent for future designers to consider in a library retrofit.
  • Analysis of the Built Environment of Manufactured Housing Communities in Tucson, Arizona

    Sandoval, Myriam; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey (The University of Arizona., 2021-05-14)
    This study will analyze the built environments of three large, manufactured housing communities in Tucson, Arizona. The three communities were chosen using existing research of manufactured housing density in Pima County. With the implementation of a rating system incorporating aspects of the United Nations’ Sustainable Development Goals and the SITES Rating system, the three communities were assessed on several criteria, each on a scale of one to five. The essential problem that the built environment of manufactured communities face is an abundance of asphalt and a lacking green open space and shading. The research question being posed will determine which of the three manufactured communities suffers the most from an abundance of concrete and asphalt. From the analysis, it was determined that two of the manufactured communities, Plaza del Sol and Country Club Manufactured Housing Community, were given the same assessment from the rating system that was utilized to answer the research question. Given the limited rights residents in these communities have over land ownership, it is often challenging to achieve green infrastructure practices in these communities to promote more shading and green open space.
  • Adopting Sustainable Transportation Design: Mitigating Heat Island Effects in Tucson Communities

    Vega, Daniel; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey (The University of Arizona., 2021-05-13)
    This study looks at the communities located in two zip codes of Tucson, AZ, which are 85713 & 85757. In this research, solutions for issues such as Urban sprawl, Urban heat island effects, and insignificant usage of active transportation methods are explored. Residents of both areas participated in two surveys. We concluded that many of the residents heavily rely on automobiles for travel, especially in the area of 85757 because they are far from the major urban centers. Also, many of the residents of both zip codes felt that their neighborhood was too hot to consider active transportation methods and that activities such as biking and walking were unsafe or inaccessible. However, through the surveys, many participants are open to consider and adopt active transportation methods should their neighborhoods and built environments allow for it. We can allow this to become a reality through sustainable design. With programs such as Tucson’s complete streets and Bike Boulevards, we can promote healthier and safer transportation. A sustainable street model was developed to promote safe active transportation, create shade while lessening heat island effects, and beautify the city of Tucson.
  • Getting a Fair Share: How Developers Can Increase Development of Low-Income Housing

    Butler, James; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey (The University of Arizona., 2021-05-13)
    The growing wealth gap and lack of available low-income housing have become significant problems in the United States. Lack of available low-income housing leads to an increase in homelessness and financial hardship for low-income families. In Tucson, low-income housing options are few and far between. This project is designed to get a perspective from a property developer on why there are so few low-income housing complexes in Tucson. It also tries to identify solutions and incentives for developers to build more low-income housing complexes while still being economically viable. This project asked essential questions about low-income housing to local developers, gathering statistical data and developing a financial analysis on low-income and non-low-income properties, researching different government programs and funds available to local developers, and researching unorthodox strategies that cities or developers can implement. Through research in this project, there are particular economic and political reasons why developers avoid investing in low-income housing. Another key finding from the study is there are different programs and risk-mitigation strategies that can limit risk in investment of low-income housing development. The main incentives and strategies found that developers can use to build more low-income housing are applying for Low Income Housing Tax Credit, applying for the Tucson Community Block Grant, identifying abandoned buildings to construct low-income housing, and taking advantage of Tucson’s GPLET program. The main strategies found that the City of Tucson can implement to promote low-income housing complexes are relaxing zoning laws, building more city-owned parking garages, and removing off-street parking requirements. Developers can use this project to determine a strategy and incentives that can be used to develop low-income housing, which Tucson desperately craves.
