Approaching urban sustainability : - a minor field study in India

Brandt, Julia, Svensson, Linnéa January 2013 (has links)
This thesis aims to enable improved urban sustainability in India and has therefore been conducted at WSP’s office in Delhi. The objective has been to chart the Indian characteristics as well as to identify difficulties regarding urban sustainability. The purpose and objective have been accomplished through the implementation of three research questions. The questions have been answered by a literary review of existing theories and a complementary document analysis. Furthermore, a case study of a new development in India with long-term sustainability in focus of the design has been conducted. For an Indian city to achieve a sustainable urban development, five pillars of sustainability have been identified; political, physical, ecological, social and economic. The ecological, social and economic are pillars from the common definition of sustainability, however they have different meaning and focus in the Indian context. The physical and political pillars are therefore characteristic for the Indian urban development. The physical pillar is added in the Indian context since short term planning and focus on profit is dominating the building industry. The demand for maintenance is because of that larger than the supply which results in a need for more emphasis on the physical built environment. The political pillar is applied because of the concerns for the value and quality of governance actions. It affects the four other pillars since the government should provide guidance, both with instructions and by executions, which is not always apparent. The Indian government has introduced several strategies in order to achieve sustainability in Indian cities. Rating tools for sustainability, such as Leed and Griha, together with the planning of spatial city forms, such as compact city form and mixed land use, which are the main procedures. Benefits in terms of lower interest rates on loans and a quicker clearance are given to developers who intend to build sustainably. Though the many theories and strategies seem ambitious, they are not always as effective when translated into practice. This is partly because of the lack of follow-up and partly the clients focus on quick profit. Thus, India is facing many challenges in order to reach a sustainable urban development. Together with urbanisation and growth in population, corruption is the main challenge since many other follows. These are lack of awareness in the field of sustainability, short term planning and the focus on profit as well as public safety and poverty. If India is serious about developing its cities sustainably, it is significant for the Indian government to take an inspiring role in using and promoting sustainability.

SUSTAINABILITY ASSESSMENT AND INDICATOR DEVELOPMENT: THE ELECTRICITY SYSTEM IN DALIAN, CHINA

Rosenthal, Hendrik January 2004 (has links)
Electricity is used all over the world as a basic source of energy, essential for lighting, powering basic appliances and tools, as well as many other technologies important for today's societies. Electricity is produced, transmitted and distributed to consumers with a range of resources and technologies, resulting in a process that has impacts on sustainability. This thesis examines the interconnections among production, regulation and consumption of electricity, investigating the sustainability of the electricity system broadly defined. Under auspices of the Ecoplan China project, a case study approach is used to assess the sustainability of the electricity system in Dalian, China. Gibson (2002a) argues that sustainability ought to be conceptualized as a set of requirements, which are outlined as principles of sustainability. These principles, in this thesis, form the basis for a Sustainability Assessment of the electricity system in Dalian. The principles provide the analytical framework for reviewing the literature that discusses electricity in sustainability terms and in relation to China. Gibson's conception of sustainability is broad and does not provide guidance on specific procedures for conducting a Sustainability Assessment. The sustainability principles operate on complex systems theory and on the principle of integration, resulting in limitations for their practical application. More specifically, Gibson's principles are operationalized with electricity assessment indices derived for use in the study of Dalian. Relevant indicators are selected based on these indices. This work is exploratory in nature, as it tests the utility of the sustainability principles for assessment and indicator developent. The electricity infrastructure and system regulations relevant for Dalian were reviewed, while local consumer attitudes in relation to electricity were also examined. Dalian is dependent on coal as the primary source of electricity. Production infrastructure also includes a limited supply of wind power. A nuclear plant is being constructed in the region to reduce the need for future expansion of coal-based electricity production. The local grid infrastructure has been improved in recent years to increase efficiency of electricity transmission and to ensure that all residents have access to a reliable supply of electricity. Industrial growth and restructuring has increased the demand for electricity. The local regulatory environment is based on a centralized structure, with much input coming from provincial and state government bodies. Local consumer attitudes were investigated with a survey, in order to shed light on how sustainability and electricity are manifested in Dalian residents. This information is qualified in sustainability terms and relevant indicators are derived. The research is intended to start discussion in Dalian for developing a framework for evaluating sustainability of the electricity system and on sustainable development in general. The study supports Dalian's goal for becoming an eco-city and the results provide recommendations for further study of Dalian's electricity system. Dalian has taken steps to improve the electricity system, but a clear strategy to develop long-term sustainability is necessary. In coordination with local experts and government representatives, Ecoplan China is in a good position to further extend research for developing sustainability-based policy and planning tools for Dalian.

Green Employees: Organizational Identification in an Environmentally Friendly Company

Haugen, Jenna 01 August 2009 (has links)
Environmental sustainability is an issue facing our global society and one that must be addressed through communication in order to encourage change amongst individuals. The current research focuses on the organization, in this instance a “Green” printing company, and its role in building identification amongst employees. This study focuses on environmental sustainable practices initiated or continued by employees through the use of a directed mission statement and organizational rhetoric. Utilizing individual interviews, the findings suggest that by building organizational identification, more environmentally-friendly practices amongst organizational members may be achieved.

An Assessment of Sustainable Water Management at University Campuses

McHugh, Amani N. January 2011 (has links)
<p>Sustainable water management is needed to ensure quality supplies of our vital water resources in the face of growing human demand for water, high levels of pollution, and increasing spatial and temporal variability associated with climate change. An integrated approach to water management is recommended to address current water challenges, which are often interrelated with other environmental, economic and social issues. Universities and colleges have missions, resources, and contexts that could enable them to lead the process of developing and applying sustainable and integrated water resource management (IWRM). The opportunity to exemplify integrated water management has grown as institutions of higher education have made progress towards incorporating environmental sustainability into teaching, research, and campus operations. This dissertation examines the issue of campus water management at institutions of higher education through a review of campus sustainability literature, a survey of sustainability and facilities managers, and case studies of three campus water-related projects. </p><p>Findings from the review of campus sustainability literature and websites suggests water is less of a campus management priority than issues such as energy and climate change; furthermore, where water is addressed, the focus is on water conservation, while water quality management is overlooked. IWRM is not explicitly discussed in the campus sustainability literature reviewed, though principles relevant to IWRM are included in some campus sustainability declarations and programs. Results from the survey substantiate the findings from literature review that water management is less of an institutional priority than energy management and water quality management is often underemphasized in campus management. According to the survey respondents, campus water management at the institutions represented was on average just adequately managed and institutions were minimally prepared to deal with several types of future water problems. Facilities managers tended to rate their institution's water management as slightly more effective compared to sustainability coordinators. Many campuses relied on top-down, engineering based water management approaches, rather than integrated and interdisciplinary water management. Individual initiatives, municipal codes and policies, campus community sustainability awareness, and campus environmental projects served as drivers for more sustainable water management, while budget constrains were a common barrier. Logistic regression analysis of the survey data revealed that institutions featuring stream and wetland restoration projects had greater odds of being described as having a developed watershed plan and taking into consideration multidisciplinary approaches to water management.</p><p>Case studies showed that wetland creation and restoration projects can serve as effective teaching and research laboratories for institutions of higher education, but that none of the studied cases fully exemplified IWRM in their operation. Of the three cases studied, the Stream and Wetland Assessment Management Park project at Duke University most closely demonstrated a campus project designed and developed to address water problems in the campus watershed, while also offering an effective outdoor teaching and research laboratory for hundreds of students, professionals, and researchers. The Olentangy River Wetland Research Park case at Ohio State University exemplified the potential for wetland creation and restoration projects to serve as a facility for educating thousands of students and visitors, training dozens of water experts, and influencing wetland and water resource management beyond the campus. The Radford University Stormwater Treatment Wetland Project case illustrated the potential for institutions with limited space and resources to establish effective outdoor teaching laboratories using environmental features already present or in development on campus. </p><p> Findings from the review, survey and case studies all point toward the need and opportunity for institutions of higher education to make greater efforts at implementing and promoting sustainable and integrated water resource management. Literature review and survey findings reveal that water is frequently overlooked as environmental resource at universities and colleges, while other environmental issues such as energy, climate change and recycling are prioritized in sustainability plans and efforts. Universities and colleges have made progress addressing water conservation, while water quality and stormwater need further attention and an integrated approach for more effective management.</p> / Dissertation

Parameters Of Sustainability In Urban Residential Areas: A Critique Of Temelli/ankara

Kural, Nerkis 01 January 2009 (has links) (PDF)
The important positions and proposals of the thesis are firstly the framework posited for a socially sustainable urban environment, and secondly a proposal for the parameters of place formation for sustainable urban design. Research into social sustainability has provided a variety of approaches among which Castells&amp / #8217 / model for urban movements have been adapted as a matrix for social organization in terms of placemaking, highlighting the goals of an urban movement, in this case of a place, with the citizen as urban actor, against its adversary the historical actor. As for the parameters of place formation a matrix of place is developed as a tool for urban design and for measuring urban sustainability. The matrix delineates the six dimensions of place in terms of the three sustainabilities most strongly involved in each / to be measured by the indicators of sustainability which are to be achieved by applying various strategies for urban design. As a result of the study of the underlying dynamics of the paradigms of sustainability, place, and place-making, and the shifting role of urban design necessitated by problems of urbaproposed within a discourse that prefers to see the three sustainabilities in conjunction and, believes socially sustainable communities to be also environmentally and economically sustainable- the issue becomes how to facilitate a place process through urban design. Place as a social product, and place as an experiential, cognitive construct, place as object and subject of place-making, and place as a geographically specific, historical materialist formation are the four vantage points from which to inspect the juxtapositions and differences of the concept / and may be arrive at a theory of place. The predilection that sustainability and urbanization can be evaluated via placemaking stems, on one hand, from a study of the city/urbanization through the works of Harvey, Castells, Lefebvre and Bookchin who emphasize social space/process in the face of physical/geometric space / and an architectural background/disposition which finds place congenial on the other hand. The paradigm of sustainability and place, and place-making as urban design is applied to the case of Temelli, Ankara for a critique of sustainable/unsustainable urbanization. As a geographic, social, economic and historical location within the Greater Municipality of Ankara, Temelli has been a region of attraction for investors since the 1990s. What was once a small village planned for settling Balkan immigrants, became a municipality in 1994 / the land within the municipal boundaries were increased tenfold, and the region was earmarked for an overspill of 650,000 people from Ankara Metropolitan Area in the next 20 years. Four residential areas in the region have been assessed comparatively in terms of sustainable urban forms / and an evaluation of everyday lives have been conducted through surveys and interviews with residents to observe how and if place as social product evolved / how the conceived, perceived and lived spaces interacted.

Essays on operations strategies

Jacobs, Brian W. 15 September 2009 (has links)
Operations strategies, whether prompted by competitive or regulatory forces, can greatly impact firm performance. While operations strategies cover a wide spectrum of issues - supply chain management, technology choice, capacity allocation, etc. - this dissertation focuses on two such issues, namely, sustainability and product development. The thesis comprises three essays. The first essay (Chapter 2) examines a regulatory aspect of sustainability strategy, product take-back, a form of Extended Producer Responsibility (EPR). With a stylized model, we analyze the trade-offs between assigning full responsibility for product recovery to a single echelon in a multi-echelon supply chain versus sharing responsibility between echelons. We demonstrate how the sharing of EPR program costs between the echelons can move the supply chain closer to the coordinated profit benchmark. The second essay (Chapter 3) examines a voluntary aspect of sustainability from an empirical perspective. We investigate the impact from various types of corporate environmental initiatives and environmental awards and certifications on the market value of the firm. We find that the market is selective in reacting to environmental performance, with certain types of initiatives and awards even valued negatively. The third essay (Chapter 4) is an empirical examination of the shareholder value effects that result from the restructuring of firms' product development activities. We find that, on average, the stock market reacts positively to product development restructuring, and that the reaction is dependent on the firm's prior financial performance, restructuring objective, R&D expenditures, and size.

Relating facility performance indicators to organizational sustainability performance in public higher education facilities

Adams, Gregory Keith 07 April 2010 (has links)
This research seeks to identify how an organization's facility management (FM) practices relate with the state of sustainability in the organization. A review of the literature leads to presentation of a model defining these relationships. The concepts of direct and indirect FM sustainability roles in organizational sustainability are presented. Accepted facility metrics found in the APPA Facilities Performance Indicator Survey are used as indicators of FM in University System of Georgia institutions and are tested for correlation with sustainability best practices scores generated in an assessment performed for this research. FM performance indicators representing the direct role of FM are not found to be correlated with organizational sustainability best practicesin USG higher education organizations.

Environmental life cycle driven decision making in product design

Lu, Di 02 June 2010 (has links)
There is growing interest in the assessment of products from a life cycle perspective. Product life cycles are often dominated by extensive chemical supply chains that lead up to the materials contained in the products and the overwhelming contribution that the production of these chemicals make to the overall life cycle due to their energy intensity. Hence, chemical engineers are uniquely positioned to carry out significant components of this assessment because of their skills in chemical process design and analysis. Furthermore, the complexity and extent of life cycle concerns creates opportunities for new process systems tools to be developed to support product design and analysis. The specific thesis objectives are threefold. The first is to develop a systematic methodology to optimize material selections for a product based on life cycle inventory (LCI) characteristics. The second is to use this methodology combined with sustainability assessment standards to assess whether these standards are congruent with life cycle assessment. The third is to develop an approach to design product sustainability assessment standards that are clear and consistent with life cycle principles. The overall contributions will be in the applied domain of life cycle assessment and its integration into standards setting, and in contributions to optimization tools and methods. The three objectives will be illustrated in the domain of carpet systems. Previous research has generated a substantial database of gate-to-gate (GTG) life cycle inventories for various chemicals that make up carpet, extending from the inputs to the final carpet mill back to the natural resources such as oil, natural gas and mined calcium carbonate. Carpet recycling is a promising alternative approach for reducing life cycle impacts and is being practiced at a growing scale in the U.S. This thesis uses the specific individual LCI gate-to-gate blocks for virgin materials and for important carpet recycling and general polymer recycling processes. A database for the GTG LCI will be used to construct a virtual chemical tree that automatically that represents the potential cradle-to-gate (CTG) use of resources. The alternatives for each possible route for the product will be generated, and optimization approaches will be applied to optimize the performance of the carpet system according to life cycle objectives. Sustainability assessment standards are currently being developed for a range of building products, such as carpet, resilient flooring, commercial textile coverings and office furniture. This activity has been stimulated through the considerable success of the U.S. Green Building Council's (USGBC) LEED standard. The LEED Standard is points-based: the building design and construction earns points for having certain attributes or promoting certain activities. The points are totaled and then the building earns a rating based on the total being above a certain threshold. The second thesis objective is met through extending the LCI optimization methodology to represent point-based standards. A product can then be optimized to maximize the number of points it earns or to minimize its life cycle attributes. This approach can be used to evaluate the effectiveness of an emerging carpet sustainability standard, NSF-140, in integrating LCI into the standard. The last objective, standard design, is approached through designing the tables that award points in the standard to be consistent with life cycle information. Certain minimum principles of consistency are articulated and then the designs shown to be consistent with these principles in the case that the life cycle impact assessment method maps the life cycle inventory to impact through a linear weighting.
