Description
Given the importance of buildings as major consumers of resources worldwide, several organizations are working avidly to ensure the negative impacts of buildings are minimized. The U.S. Green Building Council's (USGBC) Leadership in Energy and Environmental Design (LEED) rating system is one such effort to recognize buildings that are designed to achieve a superior performance in several areas including energy consumption and indoor environmental quality (IEQ). The primary objectives of this study are to investigate the performance of LEED certified facilities in terms of energy consumption and occupant satisfaction with IEQ, and introduce a framework to assess the performance of LEED certified buildings.
This thesis attempts to achieve the research objectives by examining the LEED certified buildings on the Arizona State University (ASU) campus in Tempe, AZ, from two complementary perspectives: the Macro-level and the Micro-level. Heating, cooling, and electricity data were collected from the LEED-certified buildings on campus, and their energy use intensity was calculated in order to investigate the buildings' actual energy performance. Additionally, IEQ occupant satisfaction surveys were used to investigate users' satisfaction with the space layout, space furniture, thermal comfort, indoor air quality, lighting level, acoustic quality, water efficiency, cleanliness and maintenance of the facilities they occupy.
From a Macro-level perspective, the results suggest ASU LEED buildings consume less energy than regional counterparts, and exhibit higher occupant satisfaction than national counterparts. The occupant satisfaction results are in line with the literature on LEED buildings, whereas the energy results contribute to the inconclusive body of knowledge on energy performance improvements linked to LEED certification. From a Micro-level perspective, data analysis suggest an inconsistency between the LEED points earned for the Energy & Atmosphere and IEQ categories, on one hand, and the respective levels of energy consumption and occupant satisfaction on the other hand. Accordingly, this study showcases the variation in the performance results when approached from different perspectives. This contribution highlights the need to consider the Macro-level and Micro-level assessments in tandem, and assess LEED building performance from these two distinct but complementary perspectives in order to develop a more comprehensive understanding of the actual building performance.

Description
The built environment is responsible for a significant portion of global waste generation.
Construction and demolition (C&D) waste requires significant landfill areas and costs
billions of dollars. New business models that reduce this waste may prove to be financially
beneficial and generally more sustainable. One such model is referred to as the “Circular
Economy” (CE), which promotes the efficient use of materials to minimize waste
generation and raw material consumption. CE is achieved by maximizing the life of
materials and components and by reclaiming the typically wasted value at the end of their
life. This thesis identifies the potential opportunities for using CE in the built environment.
It first calculates the magnitude of C&D waste and its main streams, highlights the top
C&D materials based on weight and value using data from various regions, identifies the
top C&D materials’ current recycling and reuse rates, and finally estimates a potential
financial benefit of $3.7 billion from redirecting C&D waste using the CE concept in the
United States.

Description
Sustainable Materials Management and Circular Economy are both frameworks for considering the way we interact with the world's resources. Different organizations and institutions across the world have adopted one philosophy or the other. To some, there seems to be little overlap of the two, and to others, they are perceived as being interchangeable. This paper evaluates Sustainable Materials Management (SMM) and Circular Economy (CE) individually and in comparison to see how truly different these frameworks are from one another. This comparison is then extended into a theoretical walk-through of an SMM treatment of concrete pavement in contrast with a CE treatment. With concrete being a ubiquitous in the world's buildings and roads, as well as being a major constituent of Construction & Demolition waste generated, its analysis is applicable to a significant portion of the world's material flow. The ultimate test of differentiation between SMM and CE would ask: 1) If SMM principles guided action, would the outcomes be aligned with or at odds with CE principles? and conversely 2) If CE principles guided action, would the outcomes be aligned with or at odds with SMM principles? Using concrete pavement as an example, this paper seeks to determine whether or not Sustainable Materials Management and Circular Economy are simply different roads leading to the same destination.

Description
This case study explores the institutions and governing strategies involved in the management of Rupa Lake in Kaski district in Western Nepal, particularly Rupa Lake Rehabilitation and Fishery Cooperative. Methods used for data collection include key informant interviews, household interviews, a focus group discussion and archival records. Institutions were examined for their effectiveness in sustaining natural and socioeconomic systems as perceived by community members. Based on a literature review and the results of the data collected, this thesis builds a case study highlighting Rupa Lake Rehabilitation and Fishery Cooperative's strategies for governing its local watershed and formulates a framework for commons institutions that aim to achieve sustainable outcomes. Based on findings, I argue that no single form of governance is a panacea for solving commons problems, governing strategies should be implemented on a case-by-case basis, and institutions should be involved at multiple levels and always include local input. Additionally, a sustainable institution should provide benefits to society that it can see, function democratically and with transparency, promote a biodiverse ecosystem, elevate marginalized groups, and collaborate with other institutions. These "clumsy" institutions create a series of complex interactions that are robust and adaptive to reflect the ever-changing systems they aim to govern.

Description
In this paper, I analyze representations of nature in popular film, using the feminist / deconstructionist concept of a dualism to structure my critique. Using Val Plumwood’s analysis of the logical structure of dualism and the 5 ‘features of a dualism’ that she identifies, I critique 5 popular movies – Star Wars, Lord of the Rings, Brave, Grizzly Man, and Planet Earth – by locating within each of them one of the 5 features and explaining how the movie functions to reinforce the Nature/Culture dualism . By showing how the Nature/Culture dualism shapes and is shaped by popular cinema, I show how “Nature” is a social construct, created as part of this very dualism, and reified through popular culture. I conclude with the introduction of a number of ‘subversive’ pieces of visual art that undermine and actively deconstruct the Nature/Culture dualism and show to the viewer a more honest presentation of the non-human world.

Description
Defines the concept of the arcology as conceived by architect Paolo Soleri. Arcology combines "architecture" and "ecology" and explores a visionary notion of a self-contained urban community that has agricultural, commercial, and residential facilities under one roof. Two real-world examples of these projects are explored: Arcosanti, AZ and Masdar City, Abu Dhabi, UAE. Key aspects of the arcology that could be applied to an existing urban fabric are identified, such as urban design fostering social interaction, reduction of automobile dependency, and a development pattern that combats sprawl. Through interviews with local representatives, a holistic approach to applying arcology concepts to the Phoenix Metro Area is devised.

Description
In this project I analyze Paolo Soleri's concept of arcology \u2014 the combination of architecture and ecology \u2014 from a theoretical, symbolic, and physical perspective. I utilize these three viewpoints to determine what aspects of his theories are most effective for urban design. While his ideas are based on building "arcologies" from the ground up, I will be using the Phoenix Metropolitan area to determine how we could apply his ideas to existing cities without having to rebuild entirely. This past summer I participated in the 5-week construction workshop the Cosanti Foundation offers at the physical prototypical city of Arcosanti in Mayer, Arizona during which time I studied Soleri's work and participated in the construction of the city while also participating in the community dynamic there. I have found that while not all components of Soleri's theories translated well into Arcosanti, there are certainly some ideas that could be applied help to improve the City of Phoenix. I propose improvements to the pedestrian realm and an increase public space with an emphasis on utilizing the infrastructure and land that is already present for future development.

Description
City planners often use bicycle friendly rating schemes as tools to guide them in their efforts to establish a bicycle community. However, the criteria and methodologies used vary from program to program and often do not encapsulate all of the necessary elements that comprise true bicycle friendliness. This report documents the important elements, strategies, and best practices that well-established Dutch, Danish, and German bike friendly cities exhibit to create a baseline standard for bicycle friendliness. Not all rating programs' criteria and methodologies align perfectly within this understanding of bicycle friendliness. City planners should use these programs as tools while keeping their limitations in consideration. The City of Tempe currently uses the League of American Bicyclists Bicycle Friendly Community program and BikeScore.com. By understanding the limitations associated with these programs, Tempe should move forward in their pursuit of bicycle friendliness by using multiple rating programs simultaneously and by looking at top-rated cities' strategies to enhance their infrastructure, network, urban form, and biking culture.

Description
Social relationships are the single most factor that create joy in human lives. And yet, the ways we are building our cities and structuring our lives reduces our chances of interaction and increases isolation. Creating more public spaces may be a possible solution to this problem of declining social cohesion. Public spaces have been shown to improve rates of social cohesion and social interaction. They have also been show to have positive effects on physical health, local economies, the natural environment, reducing crime rates and psychological health. Creating public spaces in areas that are low-income or have limited amounts of space can be very challenging. This paper profiles options of community created spaces, space public spaces and temporary public spaces. All of which are options for low-income and limited space communities. The paper concludes with the summery of an active project to create a public space in such a community through a joint-use agreement.

Description
Modern American environmental social movements have strived for a better world for nearly fifty years, pushing a philosophy of careful resource use and limited consumption as an alternative to the pollution and degradation that has so far accompanied global industrialization. The reach of these movements is broad and the topic they cover is one that aligns with the values and beliefs of many; it is thus quite confusing that they've been so unsuccessful. This thesis was a response to that apparent contradiction, exploring why movements have not been as successful as both they and the public initially desired. It began by defining what social movements are and how they emerge or find success, then provided a brief history of environmentalism in America, and the different successes and failures that occurred before and after the first Earth day in 1970. Finally, it explored some of the reasons environmentalism was unsuccessful, and found that while structural barriers like politics and business interests played a role in movement outcomes, the tactics of different groups were at least partially to blame. Once this was concluded, the author used the perspectives of different activists to propose ways to enhance the quality of current movements and allow them to continue to make progress well into the future. In order to expand the audience of this thesis, the author is also working on a children;s book that illustrates many of the important themes that he hopes to convey to the public. Though drafted, the book is incomplete as of the date that documents are due for Barrett review.
