The Urban Infrastructure For Sustainability: Learning From Kigali, Marwan Ghandour Jul 2019

The Urban Infrastructure For Sustainability: Learning From Kigali, Marwan Ghandour

Marwan Ghandour

Until 2013, when a new master plan for the city was approved, Kigali had very few urban regulations in place. Incremental constructions, usually associated with informal urbanization, were the norm rather than the exception. Most of the city fabric grew organically creating a unique configuration of urban adjacencies, which would be improbable for planners and designers to imagine. This configuration is particular to the geographic, economic and social conditions of the city as incremental urbanization slowly adjusted to the living conditions, through the actions of thousands of city residents over a long period of time. These actions were formed in …

Diallo Noumoussara Capstone Paper Final Version.Docx, Noumoussara Diallo

Noumoussara Diallo

Abstract
The Sudano‐Sahelian region of West Africa is one of the poorest regions in the world. It is characterized by high rainfall variability and rapid population growth. Despite centuries of experience adapting to severe natural conditions, the vulnerability of the Sahel and its population to increased climate variability and change is of great concern.
Our research focuses on understanding farmers’ perceptions of climate change and the types of adjustments they have made in their farming practices in Senegal. It is based on a qualitative approach of semi-structured interviews to understand how environmental variations punctuate the daily lives of local populations. …


Effect Of Biomass Inlet Concentration On Mixing In A Double Screw Pyrolyzer, Breanna L. Marmur, Theodore J. Heindel Apr 2019

Effect Of Biomass Inlet Concentration On Mixing In A Double Screw Pyrolyzer, Breanna L. Marmur, Theodore J. Heindel

Breanna L. Marmur

The renewable energy industry relies on double screw pyrolyzers to convert cellulosic biomass into bio-oil. Bio-oil can then be converted into synthetic gasoline, diesel, and other transportation fuels, or can be converted into biobased chemicals for a wide range of applications. One of the processes by which bio-oil is produced in industry today is through fast pyrolysis, the fast thermal decomposition of organic material in the absence of oxygen. One type of pyrolyzer, a double screw pyrolyzer, features two intermeshing screws encased in a reactor which mechanically conveys and mixes the biomass and heat carrier media. The mixing effectiveness of …

Climate Change, Cattle, And The Challenge Of Sustainability In A Telecoupled System In Africa, Tara S. Easter, Alexander K. Killion, Neil H. Carter Mar 2018

Climate Change, Cattle, And The Challenge Of Sustainability In A Telecoupled System In Africa, Tara S. Easter, Alexander K. Killion, Neil H. Carter

Neil H. Carter

Information, energy, and materials are flowing over greater distances than in the past, changing the structure and feedbacks within and across coupled human and natural systems worldwide. The telecoupling framework was recently developed to understand the feedbacks and multidirectional flows characterizing social and environmental interactions between distant systems. We extend the application of the telecoupling framework to illustrate how flows in beef affect and are affected by social-ecological processes occurring between distant systems in Africa, and how those dynamics will likely change over the next few decades because of climate-induced shifts in a major bovine disease, trypanosomosis. The disease is …

Biobased Products And The Leed® Rating System, Meredith Chambers, Mikesch Muecke Nov 2017

Biobased Products And The Leed® Rating System, Meredith Chambers, Mikesch Muecke

Mikesch Muecke

At the beginning of the 20th century, over 40% by weight of all the materials consumed through the production of goods within the United States were comprised of renewable resources (Matos and Wagner 1998). In contrast, by the end of the 20th century renewable material usage had dropped to less than 8% by weight (Matos and Wagner 1998). Combined with both an increase in the overall rate at which we consume resources as well as growing awareness of the inherently finite availability of nonrenewable resources, the early decades of the 21st century may mark the beginning of a shift back …


A Smartphone-Based Device For Measuring Soil Organic Matter, Meng Lu Jun 2017

A Smartphone-Based Device For Measuring Soil Organic Matter, Meng Lu

Meng Lu

The project evaluated the potential of utilizing a smartphone-based system for the in-field analysis of Soil Organic Matter. Although it demonstrated that the performance of the smartphone-based spectrometer can be comparable to commercial spectrometers, the results suggest that it is challenging to identify the spectral “signatures” of the SOM due to the morphology and moisture variation of soil samples.


A Period Examination Through Contemporary Energy Analysis Of Kevin Roche’S Fine Arts Center At University Of Massachusetts-Amherst, L Carl Fiocchi Jr May 2017

A Period Examination Through Contemporary Energy Analysis Of Kevin Roche’S Fine Arts Center At University Of Massachusetts-Amherst, L Carl Fiocchi Jr

L. Carl Fiocchi

Studies of buildings belonging to a subset of Modernist architecture, Brutalism, have included discussions pertaining to social and architectural history, critical reception, tectonic form and geometry inspirations, material property selections, period technology limitations, and migration of public perceptions. Evaluations of Brutalist buildings’ energy related performances have been restricted to anecdotal observations with particular focus on the building type’s poor thermal performance, a result of the preferred construction method, i.e. monolithic reinforced concrete used as structure, interior finish and exterior finish. A valid criticism, but one that served to dismiss discussion that the possibility of other positive design strategies limiting energy …

Optimizing Compressed Air Storage For Energy Efficiency, Brian Abels, J. Kelly Kissock Mar 2017

Optimizing Compressed Air Storage For Energy Efficiency, Brian Abels, J. Kelly Kissock

J. Kelly Kissock

Compressed air storage is an important, but often misunderstood, component of compressed air systems. This paper discusses methods to properly size compressed air storage in load-unload systems to avoid short cycling and reduce system energy use. First, key equations relating storage, pressure, and compressed air flow are derived using fundamental thermodynamic relations. Next, these relations are used to calculate the relation between volume of storage and cycle time in load-unload compressors. It is shown that cycle time is minimized when compressed air demand is 50% of compressor capacity. The effect of pressure drop between compressor system and storage on cycle …


Lean Energy Analysis: Identifying, Discovering And Tracking Energy Savings Potential, J. Kelly Kissock, John Seryak Mar 2017

Lean Energy Analysis: Identifying, Discovering And Tracking Energy Savings Potential, J. Kelly Kissock, John Seryak

J. Kelly Kissock

Energy in manufacturing facilities is used for direct production of goods, space conditioning, and general facility support such as lighting. This paper presents a methodology, called lean energy analysis, LEA, for graphically and statistically analyzing plant energy use in terms of these major end uses.

The LEA methodology uses as few as 60 easily obtainable data points. Multivariable change-point models of electricity and natural gas use as functions of outdoor air temperature and production data are developed. The statistical models are used to subdivide plant energy use into facility, space-conditioning and production-related components.

These breakdowns suggest the savings potential from …

Improving Compressed Air Energy Efficiency In Automotive Plants: Practical Examples And Implementation, Nasr Alkadi, J. Kelly Kissock

J. Kelly Kissock

The automotive industry is the largest industry in the United States in terms of the dollar value of production [1]. U.S. automakers face tremendous pressure from foreign competitors, which have an increasing manufacturing presence in this country. The Big Three North American Original Equipment Manufacturers (OEMs)-General Motors, Ford, and Chrysler-are reacting to declining sales figures and economic strain by working more efficiently and seeking out opportunities to reduce production costs without negatively affecting the production volume or the quality of the product. Successful, cost-effective investment and implementation of the energy efficiency technologies and practices meet the challenge of maintaining the …


Energy Efficient Process Heating: Managing Air Flow, Kevin Carpenter, J. Kelly Kissock Mar 2017

Energy Efficient Process Heating: Managing Air Flow, Kevin Carpenter, J. Kelly Kissock

J. Kelly Kissock

Much energy is lost through excess air flow in and out of process heating equipment. Energy saving opportunities from managing air flow include minimizing combustion air, preheating combustion air, minimizing ventilation air, and reconfiguring openings to reduce leakage.

This paper identifies these opportunities and presents methods to quantify potential energy savings from implementing these energy-savings measures. Case study examples are used to demonstrate the methods and the potential energy savings.The method for calculating savings from minimizing combustion air accounts for improvement in efficiency from increased combustion temperature and decreased combustion gas mass flow rate.

The method for calculating savings from …


Measuring Plant-Wide Energy Savings, J. Kelly Kissock, Carl Eger Mar 2017

Measuring Plant-Wide Energy Savings, J. Kelly Kissock, Carl Eger

J. Kelly Kissock

This paper presents a general method for measuring plant-wide industrial energy savings and demonstrates the method using a case study from an actual industrial energy assessment. The method uses regression models to characterize baseline energy use. It takes into account changes in weather and production, and can use sub-metered data or whole plant utility billing data. In addition to calculating overall savings, the method is also able to disaggregate savings into components, which provides additional insight into the effectiveness of the individual savings measures. Although the method incorporates search techniques and multi-variable least-squares regression, it is easily implemented using data …

Enhancing Public Engagement On Offshore Wind Energy Using Genius Loci: A Case Study From A Lake Michigan Coastal Community, Erik Edward Nordman, Daniel O'Keefe, Erika Arndt Sep 2016

Enhancing Public Engagement On Offshore Wind Energy Using Genius Loci: A Case Study From A Lake Michigan Coastal Community, Erik Edward Nordman, Daniel O'Keefe, Erika Arndt

Erik Edward Nordman

We describe a novel approach to public engagement on offshore wind energy based on genius loci (“spirit of a place”). North America lacks offshore wind farms but they could be viable in the Great Lakes. Cultural ties between coastal Michigan, USA and the Netherlands offered opportunities to learn from the Dutch offshore wind experience. Residents from a Lake Michigan coastal community with Dutch heritage videoconferenced with a Dutch tourism specialist regarding the Egmond aan Zee offshore wind farm. Important differences and similarities between the regions emerged, including the clustering of technological expertise, tourism effects, and perspectives on working seascapes. Michigan …


Prioritizing Investment In Residential Energy Efficiency And Renewable Energy: A Case Study For The U.S. Midwest, Robert J. Brecha, Austin Mitchell, Kevin P. Hallinan, J. Kelly Kissock Sep 2016

Prioritizing Investment In Residential Energy Efficiency And Renewable Energy: A Case Study For The U.S. Midwest, Robert J. Brecha, Austin Mitchell, Kevin P. Hallinan, J. Kelly Kissock

J. Kissock

Residential building energy use is an important contributor to greenhouse gas emissions and in the United States represents about 20% of total energy consumption. A number of previous macro-scale studies of residential energy consumption and energy-efficiency improvements are mainly concerned with national or international aggregate potential savings. In this paper we look into the details of how a collection of specific homes in one region might reduce energy consumption and carbon emissions, with particular attention given to some practical limits to what can be achieved by upgrading the existing residential building stock. Using a simple model of residential, single-family home …

Transformative Education For Sustainability Transition At Edith Cowan University: A Discussion Paper, Sandra Woolltorton Jun 2016

Transformative Education For Sustainability Transition At Edith Cowan University: A Discussion Paper, Sandra Woolltorton

Sandra Wooltorton

"Recently the Australian Government released a National Action Plan for sustainability education (DEWHA, 2009) that prescribes for universities a reorientation to sustainability through teaching and learning, research and campus management. It specifies a transformative approach to education, together with a whole‐of‐school, whole‐of‐system philosophy. In this paper I define ‘transformative education’ in the context of sustainability and discuss the implications of the National Action Plan for Edith Cowan University. I also conduct a reconnaissance of the sustainability websites of a small sample of international universities to consider the depth of their transformative approaches to teaching and learning. Finally, I ‘throw down …


Emissions Scenarios In The Face Of Fossil-Fuel Peaking, Robert Brecha Feb 2016

Emissions Scenarios In The Face Of Fossil-Fuel Peaking, Robert Brecha

Robert J. Brecha

Emissions scenarios used by the Intergovernmental Panel on Climate Change (IPCC) are based on detailed energy system models in which demographics, technology and economics are used to generate projections of future world energy consumption, and therefore, of greenhouse gas emissions. We propose in this paper that it is useful to look at a qualitative model of the energy system, backed by data from short- and medium-term trends, to gain a sense of carbon emission bounds. Here we look at what may be considered a lower bound for 21st century emissions given two assumptions: first, that extractable fossil-fuel resources follow the …
