A Method For Selecting Hvac Retrofit Solutions For Existing Small- And Medium-Sized Commercial Buildings, Bonggil Jeon Dec 2016

A Method For Selecting Hvac Retrofit Solutions For Existing Small- And Medium-Sized Commercial Buildings, Bonggil Jeon

Open Access Dissertations

The primary purpose of the present study is to develop a framework and methodology for evaluating appropriate Heating, Ventilating, and Air Conditioning (HVAC) retrofit solutions that can be effectively retrofitted into different types of small- and medium-sized commercial buildings (SMSCB). Additionally, development of an advanced data-driven decision-making tool is introduced as a benefit of proposed framework. In recent years, considerable attention has been focused on retrofits of existing commercial buildings (IBE, 2013b). In fact, the Commercial Building Energy Consumption Survey (CBECS) 2003 (EIA, 2006) indicates that over 70% of existing commercial buildings across the United States are more than twenty ...


Technical Communication In Place-Making Professions: Exploring The Network Pictures Of Urban Designers, Fernando Sanchez Apr 2016

Technical Communication In Place-Making Professions: Exploring The Network Pictures Of Urban Designers, Fernando Sanchez

Open Access Dissertations

This dissertation addresses how professional writing as a field can pay attention to broader definitions of design in order to help further conversations of spatial justice (the act of helping to promote equity in matters of development in urban spaces). I begin by noting the conversations that have circulated regarding the relationship between urban design and rhetoric, noting that professional writing can help add a unique lens to the conversation. The second chapter provides an overview of how design is discussed in technical communication scholarship. Here, I showcase how most of these discussions regarding research in design have centered on ...


Modeling Person-To-Person Contaminant Transport In Enclosed Environments, Chun Chen Apr 2015

Modeling Person-To-Person Contaminant Transport In Enclosed Environments, Chun Chen

Open Access Dissertations

It is essential to predict person-to-person contaminant transport in enclosed environments to improve air distribution design and reduce the infection risk from airborne infectious diseases. This study aims to improve and accelerate the simulation of person-to-person contaminant transport in enclosed environments. ^ This investigation first conducted experimental measurements of person-to-person contaminant transport in an office mockup and the first-class cabin of a functional MD-82 aircraft. The experimental data of steady-state airflow, temperature, and gas contaminant concentration fields obtained in the office were used to validate the steady-state computational fluid dynamics (CFD) models. In the aircraft cabin, the transient particle concentrations were ...


Social Vulnerability, Green Infrastructure, Urbanization And Climate Change-Induced Flooding: A Risk Assessment For The Charles River Watershed, Massachusetts, Usa, Chingwen Cheng Sep 2013

Social Vulnerability, Green Infrastructure, Urbanization And Climate Change-Induced Flooding: A Risk Assessment For The Charles River Watershed, Massachusetts, Usa, Chingwen Cheng

Open Access Dissertations

Climate change is projected to increase the intensity and frequency of storm events that would increase flooding hazards. Urbanization associated with land use and land cover change has altered hydrological cycles by increasing stormwater runoff, reducing baseflow and increasing flooding hazards. Combined urbanization and climate change impacts on long-term riparian flooding during future growth are likely to affect more socially vulnerable populations. Growth strategies and green infrastructure are critical planning interventions for minimizing urbanization impacts and mitigating flooding hazards. Within the social-ecological systems planning framework, this empirical research evaluated the effects of planning interventions (infill development and stormwater detention) through ...


Climate Change Adaptation: A Green Infrastructure Planning Framework For Resilient Urban Regions, Yaser F. Abunnasr Sep 2013

Climate Change Adaptation: A Green Infrastructure Planning Framework For Resilient Urban Regions, Yaser F. Abunnasr

Open Access Dissertations

The research explores multiple facets of a green infrastructure planning framework for climate change adaptation in urban regions. The research is organized in three distinct, but related parts. The first develops an adaptation implementation model based on triggering conditions rather than time. The approach responds to policy makers' reluctance to engage in adaptation planning due to uncertain future conditions. The model is based on planning and adaptation literature and applied to two case studies. Uncertainty during implementation may be reduced by incremental and flexible policy implementation, disbursing investments as needs arise, monitoring conditions, and organizing adaptation measures along no-regrets to ...


From Tank Trails To Technology Parks: The Impact Of Base Redevelopment For New England, Bernd F. Schliemann May 2012

From Tank Trails To Technology Parks: The Impact Of Base Redevelopment For New England, Bernd F. Schliemann

Open Access Dissertations

Why do some communities thrive after closure of a major employment center such as a military base, while others suffer for many years with long-term unemployment, decaying infrastructure, or other indicators of a weak economy? Through a mixed-methods approach, this paper examines a wide variety of community characteristics from past base closures, builds a model of the most relevant indicators of success or failure, and then offers redevelopment lessons to communities facing base redevelopment. This research incorporates a multivariate statistical analysis including panel regression and then a historical study of the five major BRAC closures in New England. While strong ...


Preserving Urban Landscapes As Public History --- A Qualitative Study Of Kensington Market, Toronto, Na Li Feb 2011

Preserving Urban Landscapes As Public History --- A Qualitative Study Of Kensington Market, Toronto, Na Li

Open Access Dissertations

Situated within the interpretive and critical traditions, this study aims to contribute to one of the continuing primary themes in urban preservation: how to interpret and preserve the intangible values of built environments. A comprehensive analysis of dominant theories of urban preservation forms the conceptual framework within which this dissertation takes place. It starts by locating the intellectual context of preservation in North America, and examines its basic premises and core issues. It identifies three limits to the traditional approach to preservation planning. The complexity and fragility of history, its narrative quality and its particularities, its emotional content and economic ...


Building Main Street: Village Improvement And The Small Town Ideal, Kirin Makker Sep 2010

Building Main Street: Village Improvement And The Small Town Ideal, Kirin Makker

Open Access Dissertations

Before the American small town was enshrined as an ideal, it was a space of dynamic and pioneering progressive reform, a narrative that has been largely untold in histories of professional planning and landscape history. Archival research shows that village improvement was not simply a prequel to the City Beautiful in the years following the 1893 Chicago Expo, but a rich and complex history that places the residential village at the center of debates about the middle landscape as a civic realm comprised of complimentary and oppositional pastoral and urban worldviews. The second half of the nineteenth century saw an ...


Greenspace Conservation Planning Framework For Urban Regions Based On A Forest Bird-Habitat Relationship Study And The Resilience Thinking, Sadahisa Kato May 2010

Greenspace Conservation Planning Framework For Urban Regions Based On A Forest Bird-Habitat Relationship Study And The Resilience Thinking, Sadahisa Kato

Open Access Dissertations

The research involves first conducting a "case study" of ecological data and applying the results, together with the resilience concept, to the development of a greenspace conservation planning framework for urban regions. The first part of the research investigates the relationship between forest bird abundance and the surrounding landscape characteristics, especially, forest area and its spatial configuration in urban regions at multiple scales. The results are similar for simple and multiple regression analyses across three scales. The percentage of forest cover in a landscape is positively correlated with bird abundance with some thresholds. Overall, the percentage of forest cover in ...


An Assessment Of Natural Resources Management Conflicts In The Working Landscapes Of Mediterranean Turkey (Turkiye): Koprulu Kanyon National Park, Nedim Kemer May 2009

An Assessment Of Natural Resources Management Conflicts In The Working Landscapes Of Mediterranean Turkey (Turkiye): Koprulu Kanyon National Park, Nedim Kemer

Open Access Dissertations

Environmental conservation and natural resources management are critical global issues of the 21st century. The management of protected public lands emerges as a challenge particularly in developing countries because of the biophysical and socio-cultural importance of these lands. These lands are often referred to as 'working landscapes' where the natural systems and the collective actions of local residents have shaped one another in well-balanced interactions for generations. The working landscapes of the Köprülü Kanyon National Park (KKNP) in Turkey have provided the case study for this dissertation. Eleven villages exist within the park with a total of approximately 7,100 ...
