Unintended Social And Economic Consequences Resulting From The Implementation Of New Construction Technologies In The Developing World, Andrew J. South Jul 2011

Unintended Social And Economic Consequences Resulting From The Implementation Of New Construction Technologies In The Developing World, Andrew J. South

Theses and Dissertations

One of the key components of international development is to provide adequate shelter for citizens of developing countries. This is often accomplished by governmental, non- governmental, and private organizations that seek to lower the cost, increase the quality, and expand the availability of safe, sustainable housing through the use of innovative technologies. These new technologies can affect the social and/or economic structure within communities. This paper is a case study resulting from the construction of a seventy-one-home village, including infrastructure, near Yogyakarta, Indonesia by a foreign, aid-based non-governmental organization (NGO). The village was relocated less than two kilometers from its …


Economic Input-Output Life Cycle Assessment Of Water Reuse Strategies In Residential Buildings And Communities, Derek J. Gardels May 2011

Economic Input-Output Life Cycle Assessment Of Water Reuse Strategies In Residential Buildings And Communities, Derek J. Gardels

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

The objective of this study was to determine the environmental sustainability and economic feasibility of five water reuse designs using economic input-output life cycle assessments and benefit/cost analyses. These five water reuse designs were evaluated for four regions of the United States including the Northwest (Seattle), Southwest (Scottsdale), Midwest (Omaha), and Southeast (Tampa). The water reuse designs include a greywater reuse system with no treatment for sub-surface landscape irrigation for a single-family residential house (Model 1), an indoor greywater reuse system with treatment for toilet flushing and laundry washing for a single-family residential house (Model 2), a hybrid untreated greywater …


The Shifting Terrain Of Risk And Uncertainty On The Liability Insurance Field, Tom Baker Feb 2011

The Shifting Terrain Of Risk And Uncertainty On The Liability Insurance Field, Tom Baker

All Faculty Scholarship

Recent sociological and historical work suggests that insurance risks often are not reliably calculable, except in hindsight. Insurance is “an uncertain business,” characterized by competition for premiums that pushes insurers into the unknown. This essay takes some preliminary steps that extend this insight into the liability insurance field. The essay first provides a simple quantitative comparison of U.S. property and liability insurance premiums over the last sixty years, setting the stage to make three points: (1) liability insurance premiums have grown at a similar rate as property insurance premiums and GDP over this period, providing yet another piece of evidence …


A Financial Impact Assessment Of Ld 1725: Stream Crossings, New England Environmental Finance Center, Muskie School Of Public Service Jan 2011

A Financial Impact Assessment Of Ld 1725: Stream Crossings, New England Environmental Finance Center, Muskie School Of Public Service

Water

This report looks at the potential financial impact of LD 1725 on the estimated 30,000 stream crossings in the State of Maine that would be affected by the law. Our research for this report included the analysis of nearly 2000 stream crossings and the data collection necessary for the development of extensive stream crossing replacement cost models. We found that the 1.2 bankfull requirements in LD 1725 would result in a 75% ‐ 250% increase in structure widths for stream crossing projects across the state. An upsize of this magnitude would increase the cost of replacing stream crossings statewide by …

Cap-And-Trade Modeling And Analysis For Electric Power Generation Systems, Patricio Rocha Jan 2011

Cap-And-Trade Modeling And Analysis For Electric Power Generation Systems, Patricio Rocha

USF Tampa Graduate Theses and Dissertations

Cap-and-trade is the most discussed CO2 emissions control scheme in the U.S. It is a market-based mechanism that has been used previously to successfully reduce the levels of SO2 and NOx emitted by power generators. Since electricity generators are responsible for about 40% of the CO2 emissions in the U.S., the implementation of CO2 cap-and-trade will have a significant impact on electric power generation systems. In particular, cap-and-trade will influence the investment decisions made by power generators. These decisions in turn, will affect electricity prices and demand. If the allowances (or emission permits) created by …

Energy Efficiency Technologies For Buildings: Potential For Energy, Cost, And Carbon Emission Savings, Bukola S. Jimoh Jan 2011

Energy Efficiency Technologies For Buildings: Potential For Energy, Cost, And Carbon Emission Savings, Bukola S. Jimoh

CMC Senior Theses

Buildings are a significant energy consumer and are responsible for an increasingly large percent of worldwide greenhouse gas emissions, currently between 30 and 40 percent. Energy efficiency presents unique opportunities for building owners to reduce their environmental footprint and add value through cost savings, tax deductions, and increased market value. An analysis of 183 samples of efficiency measures in seven technology categories found that 74% of efficiency investments had a positive net present value. Building automation system and chiller plant improvements had the highest mean energy and carbon dioxide savings per square foot. Additionally, building automation systems had, on average …
