The Influence Of Light In The Built Environment To Improve Mental Health Outcomes, Nathanael T. Kohl
Theses and Dissertations
Current mental health statistics for US active duty and Veteran members justify research into the causes and remedies for those plagued with negative mental health outcomes. Recent research has suggested that the built environment is connected to our mental health. This study investigated this connection with active duty and Veteran populations across the US. A literature review was completed on what factors of light in the built environment affects mental health outcomes. An analysis of active duty and Veteran mental health symptoms and the natural light rating in their residence was completed to understand the design changes that can be …
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.
Selecting The Best Thermal Building Insulation Using A Multi-Attribute Decision Model, Theodore J. Sotoropolis
Selecting The Best Thermal Building Insulation Using A Multi-Attribute Decision Model, Theodore J. Sotoropolis
Theses and Dissertations
Thermal building insulation has traditionally been viewed as a means to reduce thermal conductivity through the building envelope. Builders typically choose the least expensive material which meets the specifications in order to remain competitive. Other factors regarding long term health and environmental consequences are typically dismissed. However, a recent shift toward sustainability requires that architects and engineers take a more responsible approach to building design. This research takes a holistic approach to selecting thermal building insulation through the use of a multi-attribute decision model. Several types of insulating products from a variety of manufacturers were investigated in order to determine …
Mining Association Rules Between Credits In The Leadership In Energy And Environmental Design For New Construction (Leed-Nc) Green Building Assessment System, Benjamin J. Thomas
Mining Association Rules Between Credits In The Leadership In Energy And Environmental Design For New Construction (Leed-Nc) Green Building Assessment System, Benjamin J. Thomas
Theses and Dissertations
The Leadership in Energy and Environmental Design (LEED) Building Assessment System is a performance-based tool for determining the environmental impact of a facility from the whole-building perspective. Taking this vision into account, the individual credits that comprise LEED are designed to reward design teams for employing sustainable design strategies that reduce the total environmental impact across several sustainability issues. This study analyzed projects that have been certified in LEED for New Construction (LEED-NC) versions 2.0 and 2.1. Data on the credits achieved by the projects were mined using the Apriori algorithm which produced 641 association rules. These results were then …
Sustainable Design Policy And Leadership In Energy And Environmental Design Certification, David M. Nyikos
Sustainable Design Policy And Leadership In Energy And Environmental Design Certification, David M. Nyikos
Theses and Dissertations
The 2007 Air Force Sustainable Development and Design Policy mandates the use of Leadership in Energy and Environmental Design (LEED ) criteria for military construction projects. Additionally, the policy authorizes adding two percent of the original building budget to the total building budget in order to fund the resulting sustainable design costs. To determine if the specific sustainable design goals of this policy had statistical support in the population of LEED certified buildings, the author gathered construction, cost, and utility data on a sample of 160 LEED certified buildings. Simple correlation and descriptive statistics were used to analyze the resulting …
Optimal Adoption Of Green Roofs: Hydrology And Public Finance Applications, Luke D. Stumme
Optimal Adoption Of Green Roofs: Hydrology And Public Finance Applications, Luke D. Stumme
Theses and Dissertations
New growth within established communities puts undue pressure on existing infrastructure which in turn, drives tax rate increases for all residents to cover. However, there are sustainable methods that municipalities can turn to that diminishes the local impacts of new growth on the community. Based on the absorptive nature of green roofs, the delayed release of stored rainfall volume diminishes the instances of combined sewer outflows as well as reduces the need for increased infrastructure to convey and treat stormwater discharge. A municipality can introduce planned percentages of green roof coverage which will diminish infrastructure improvement costs over time and …
The Costs Of Not Using Green Design In The Usaf: Would Using Green Building Design Have Resulted In Life Cycle Cost Savings?, John Kimball Osborne
The Costs Of Not Using Green Design In The Usaf: Would Using Green Building Design Have Resulted In Life Cycle Cost Savings?, John Kimball Osborne
Theses and Dissertations
This study’s purpose is to determine if using green building design would have resulted in life cycle costs savings for the United States Air Force. Green designs are those that employ steps to mitigate the impacts facilities have on the environment by using resources more efficiently than conventional design. The prevailing ranking system for green design in the United States is the Leadership in Energy and Environmental Design (LEED) rating system which evaluates facilities on certain characteristics, assigning point values that translate to non-certified, certified, silver, gold, or platinum ratings. The author attempts here to show how previous studies indicated …

The research questions were answered through a comprehensive literature review, rudimentary quantitative analysis, and architectural design. The research indicated the feasibility of incorporating indigenous design into facility construction on expeditionary installations to improve building …
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
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 …
