Evaluating Long-Range Transportation Plans For Mainstreaming Of Climate Adaptation Among Virginia Mpos, Sebastian L. Shetty
Evaluating Long-Range Transportation Plans For Mainstreaming Of Climate Adaptation Among Virginia Mpos, Sebastian L. Shetty
Theses and Dissertations
Despite the strides made towards addressing climate change through greenhouse gas (GHG) emissions reduction strategies, it has become increasingly apparent that attempting to mitigate the crisis in such a manner alone is insufficient. This thesis joins a growing body of research on how our societies must adapt to a changing climate, contributing more evidence on common barriers to adaptation and how they might be overcome. Through an attempt to evaluate the progress made towards mainstreaming, or integrating, climate change concerns into five Virginia MPOs’ long-range transportation plans (LRTPs), this study provides support for prior hypotheses around the potential for MPOs …
Optimizing The Environmental And Economic Sustainability Of Contingency Base Infrastructure, Jamie E. Filer
Optimizing The Environmental And Economic Sustainability Of Contingency Base Infrastructure, Jamie E. Filer
Theses and Dissertations
Contingency bases are often located in remote areas with limited access to established infrastructure grids. This isolation leads to standalone systems comprised of inefficient, resource-dependent infrastructure, which yields a significant logistical burden, creates negative environmental impacts, and increases costs. Planners can mitigate these negative impacts by selecting sustainable technologies. However, such alternatives often come at a higher procurement cost and mobilization requirement. Accordingly, this study aims to develop and implement a novel infrastructure sustainability assessment model capable of optimizing the tradeoffs between environmental and economic performance of infrastructure alternatives.
The Built Landscape And Ecological Behavior: Patterns For Readdressing Environmental Thinking In Residence Hall Design, Sarah Keogh
Theses and Dissertations
This research addresses how architectural design processes and practices are implicated and/or reflected in social constructions of ecological thinking. It is generally recognized that human behaviors are affecting climate change and giving rise to a plethora of ecological issues; yet a transformation of widespread behavior has not yet followed. This raises questions. In the field of architecture, how can the built landscape function to encourage and support sustainable behavior patterns?
Looking at universities as locations that are embedded in their urban contexts and have influence both on their surrounding communities and on year after year of students who pass through, …
Optimal Design Of Green Roofs: Mathematical Model And Experimental Evidence, Jing Hong
Optimal Design Of Green Roofs: Mathematical Model And Experimental Evidence, Jing Hong
Theses and Dissertations
Green roofs ease the heat island effect and decrease stormwater runoff. Optimizing green roof design helps achieve these goals more efficiently. This dissertation proposes energy and mass models of green roofs and validates them through experimental evidence.
The energy and mass transfer models proposed in this dissertation can be programmed in any simulation tools, and benefits architects and engineers optimizing their green roof design. The mathematical models of green roofs were validated by the measured soil temperature and water content of the Golda Meir Library green roof.
Using energy and mass balance models, this research found the effects of the …
An Investigation Of Daylighting Performance In Sidelit Spaces, Zhe Kong
An Investigation Of Daylighting Performance In Sidelit Spaces, Zhe Kong
Theses and Dissertations
The positive influence of daylight on people’s work and well-being has been confirmed in many studies. However, excessive daylight causes discomfort glare, which decreases work productivity, impairs occupants’ vision, and may even cause headaches. Substantial studies explored glare by correlating physical lighting measurements and subjective evaluations. With the development of High Dynamic Range (HDR) image techniques, dynamic changes of daylighting distributions can be effectively captured. Consequently, more studies paired HDR image techniques with subject evaluations to explore glare. However, studies merely relying on field measurements are not only time-consuming and labor-intensive but may also disturb occupants. To address these problems, …
Reducing The Environmental Impacts Of Building Materials: Embodied Energy Analysis Of A High-Performance Building, Layla Qarout
Reducing The Environmental Impacts Of Building Materials: Embodied Energy Analysis Of A High-Performance Building, Layla Qarout
Theses and Dissertations
The purpose of this research was to assess the embodied energy and carbon emissions of structural building materials, and determine environmental savings associated with construction. In common architectural practice, the analysis of the environmental cost of materials is typically not taken into account. This can be attributed to the lack of available data, loyalty to conventional construction methods, and complexity of embodied energy calculations. Although efforts are made to ensure accuracy of the information contained in energy databases, they are based on public domain sources and the “best” energy and carbon coefficients, with no guarantee to accuracy. Therefore, it is …

Speed And Resolution In The Age Of Technological Reproducibility, Shawn Taylor
Theses and Dissertations
The rate of acceleration of the biologic and synthetic world has for a while now, been in the process of exponentially speeding up, maxing out servers and landfills, merging with each other, destroying each other. The last prehistoric relics on Earth are absorbing the same oxygen, carbon dioxide and electronic waves in our biosphere as us.

Selecting Energy Efficient Building Envelope Retrofits To Existing Department Of Defense Building Using Value Focused Thinking, David M. Pratt
Selecting Energy Efficient Building Envelope Retrofits To Existing Department Of Defense Building Using Value Focused Thinking, David M. Pratt
Theses and Dissertations
The Department of Defense (DoD) has hundreds of thousands of facilities in its inventory, which consume billions of BTUSs of energy per year. Much of that energy is used to heat and cool the facility, and a great deal of this energy is lost through the building envelope. While new military construction works towards energy efficiency, the majority of DoD facilities were built over forty years ago with little regard to energy efficiency, and it is these facilities that have the greatest potential for energy efficient building envelope retrofits. There are hundreds of various new building envelope technologies available to …
Making The Business Case For Sustainable Design In The Department Of Defense, David M. Warnke
Making The Business Case For Sustainable Design In The Department Of Defense, David M. Warnke
Theses and Dissertations
Buildings are one of the largest consumers of natural resources, a major source of ecological pollution, and occasionally toxic to human health. Sustainable design is the common term associated with buildings which, during their construction, use, and eventual disposal, seek to minimize their negative impact on the environment and human health. The U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) rating system helps to assess a building's sustainability level. In the Federal Government's push to set the example for the rest of the nation, nearly every Federal Agency has chosen to adopt the LEED assessment tool. Each …

An Evaluation Of Vegetated Roofing Technology: Application At Air Force Plant Four, Building 15, Benjamin J. Morgan
Theses and Dissertations
The United States Air Force maintains thousands of facilities around the world. Many of these facilities have asphalt built up roofs or some other less than sustainable roofing system. In an effort to find roofing systems suitable for Air Force facilities that are both economically and environmentally friendly, this thesis investigated vegetated roofing as a possible alternative to conventional roofing systems. While vegetated roofs are a relatively new roofing system, they exhibit performance qualities that seem to be in line with Air Force needs. An investigation into the feasibility of vegetated roofing technology revealed that this roofing system has many …
