A Multicriteria Based Quantitative Framework For Assessing Sustainability Of Pile Foundations, Aditi Misra

Master's Theses

ABSTRACT

Civil Engineering is the major instrument of anthropocentric development over centuries through ever expanding infrastructure, cities and facilities. Civil engineering processes are both resource and fuel intensive. The building industry alone, during the construction stage, uses about 30-40% of the total resources used in the industrialized countries. There is a growing consensus that delivering a sustainable built environment starts with incorporating sustainability thoughts at the planning and design stages of a project. Geotechnical engineering is most resource intensive although this intensive consumption of energy goes unnoticed mainly because of the indirect nature of the energy used in the …

Sustainable Practices And Related Performance Measures At State Highway Agencies, Lenahan O’Connell

Kentucky Transportation Center Research Report

This report identifies seven ways in which an SHA can harm the environment: (1) excessive consumption of virgin materials; (2) unnecessary levels or amounts of storm water runoff; (3) release of environmental contaminants by SHA employees and contractors; (4) inadequate environmental training of employees and contractors; (5) wasteful use of energy by SHA employees and contractors; (6) the promotion of excessive driving by the public and concomitant release of green house gases; and (7) inadequate oversight mechanisms and procedures to prevent unsustainable practices. The report then identifies the sustainable practices and related performance measures SHAs can use to prevent or …

Identifying Barriers To Address During The Delivery Of Sustainable Building Renovation Projects, Corey Cattano

All Theses

Architects, engineers, and contractors are continuously searching for tools and methods to reduce the unique risks associated with the delivery of construction projects. Since national policies to reduce carbon emissions and energy consumption will require drastic improvements to the existing building stock, one specific area in need of such tools is the sustainable renovation of existing buildings. The purpose of this research is to identify the barriers to address during the delivery of sustainable renovation projects and offer solutions that overcome these barriers. For example, typical renovation projects do not coordinate energy retrofits with building system renovations, resulting in poor …

Frameworks For Systemic And Structural Analysis Of Financial Innovations In Infrastructure, Ali Mostafavi, Dulcy M. Abraham

Infrastructure System-of-Systems (I-SoS ) Research Group

Financial innovations have emerged globally to close the gap between the rising global demand for infrastructures and the availability of financing sources offered by traditional financing mechanisms such as fuel taxation, tax-exempt bonds, and federal and state funds. The key to sustainable innovative financing mechanisms is effective policymaking. This paper discusses the theoretical framework of a research study whose objective is to structurally and systemically assess financial innovations in global infrastructures. The research aims to create analysis frameworks, taxonomies and constructs, and simulation models pertaining to the dynamics of the innovation process to be used in policy analysis. Structural assessment …

Increasing The Structural Engineer’S Influence Over Sustainability By Using Integrated Design Teams, Mary Elizabeth French

Masters Theses

Sustainability is quickly becoming a “buzz word” in today’s environmentally conscious world from political leaders to building professionals to design experts to consumers as they rethink their impact on current healthy, efficient indoor/outdoor environments as well as long term benefits to future generations.

This paper seeks to investigate ways to increase the structural engineer’s influence over the sustainability of the building industry by using integrated design teams. It explores current practices within the building industry, in particular the housing industry and the ways in which the integrated design team differs from most current practices. It strives to promote the positive …

Energy And Nutrient Recovery From Anaerobic Treatment Of Organic Wastes, Christian-Dominik Henrich

All Dissertations

The objective of the research was to develop a complete systems design and predictive model framework of a series of linked processes capable of providing treatment of landfill leachate while simultaneously recovering nutrients and bioenergy from the waste inputs. This proposed process includes an 'Ammonia Recovery Process' (ARP) consisting of: 1) ammonia de-sorption requiring leachate pH adjustment with lime or sodium hydroxide addition followed by, 2) ammonia re-absorption into a 6-molar sulfuric acid spray-tower followed by, 3) biological activated sludge treatment of soluble organic residuals (BOD) followed by, 4) high-rate algal post-treatment and finally, 5) an optional anaerobic digestion process …

Developing A Protocol For An Environmentally Preferable Purchasing Plus (Epp+) Program At Nasa Glenn Research Center, Amarin Kongtawelert

ETD Archive

EPP+ or Environmentally Preferable Purchasing Plus is a Environmentally Preferable Purchasing program with incorporated a unique Life Cycle Assessment (LCA) scoring system which implemented at NASA, Glenn Research Center. A protocol has been developed to aid in selecting among products based on principles of Environmentally Preferable Purchasing (EPP) and Life Cycle Assessment (LCA). The protocol has been developed for use at NASA Glenn Research Center (GRC) but is intended to benefit anyone wishing to make sustainable purchasing decision. The protocol was designed as a web-based application which evaluates the life cycle factors, affirmative procurements, price, and performance of products that …

Water Resources, Health, And The Sustainability Of Interventions To Achieve Water And Sanitation Targets Of The Millennium Development Goals In A Changing World, Lauren M. Fry

Dissertations, Master's Theses and Master's Reports - Open

This dissertation addresses sustainability of rapid provision of safe water and sanitation required to meet the Millennium Development Goals. Review of health-related literature and global statistics demonstrates engineers' role in achieving the MDGs. This review is followed by analyses relating to social, environmental, and health aspects of meeting MDG targets.

Analysis of national indicators showed that inadequate investment, poor or nonexistent policies and governance are challenges to global sanitation coverage in addition to lack of financial resources and gender disparity. Although water availability was not found to be a challenge globally, geospatial analysis demonstrated that water availability is a potentially …
