This thesis consists of three studies to better understand the environmental sustainability potential for algal-based biofuels. Initially, a comparison of recent life cycle assessments (LCA) of theoretical full-scale algal biofuel facilities was developed. These studies include varying boundaries and scope, functional units, and technology maturity assumptions. The comparison converted results...
As the negative impacts of a fossil fueled electricity market are becoming more prevalent and destructive, the necessity for alternative energy techniques increases as well. However, before commercial implementation is underway, these alternatives must be assessed from three important perspectives: environmentally, economically, and socially, which are known as the three...
The objective of this study was to compare light wood framing and traditional timber
framing quantitatively through environmental impact assessment and load path analysis. This
research was inspired by a traditional timber frame structure constructed in Vermont in 2011, and
the design of structures considered within reflect the general characteristics...
Wind energy is a promising alternative energy source due to its environmental, economic, and social benefits and, as such, has garnered public support and government incentives for its development and implementation. With the growing number of wind parks in Oregon, a life cycle assessment (LCA) study for a representative new...
Softwood plywood is one of the structural wood products studied in the CORRIM
II effort to document the environmental performance of wood product in residential
structures. Life-cycle inventory (LCI) models were developed to provide performance
data for plywood production by tracking all of its inputs and outputs in a gate-to-gate...
This thesis is the result of two research publications, which together form a framework for the evaluation of product innovativeness with potential future applications to early design. Innovation is a challenging concept to quantify. Experts seemingly have a grasp of what innovation is when they see it, however this evaluation...
Over the last 20 years, there has been rapid growth in the amount of installed wind power in the Pacific Northwest, specifically in the Columbia River Gorge. The variable and non-dispatchable nature of this resource requires that it be balanced in some form by other sources on the grid. In...
Interest in accounting for environmental impacts of products, processes, and systems during the design phase is increasing. Numerous studies have undertaken investigations for reducing environmental impacts across the product life cycle. Efforts have also been launched to quantify such impacts more accurately. Life cycle energy consumption and carbon footprint are...
The purpose of this study was to develop a slow fashion design model using the house of quality model (HOQ) to provide designers an opportunity to improve the overall sustainability of an apparel product. Slow fashion is based on the slow food movement that supports the consumption of food that...

Product care and repair services
End of life (EOL
The shoe repair transaction, as it occurs in the 5000 or so remaining shoe repair shops in the United States, is currently unexamined in academic literature for the significance it holds for either shoe repairers or their customers. Making use of both quantitative and qualitative methods of data collection, this...
Attributional and consequential life cycle assessments are useful in evaluating the environmental impacts of a process, product, or decision. Both types of life cycle assessments differ however in their scope and their ability to answer specific questions. In order to fully understand and compare the environmental impacts of a sugarcane...
Current life cycle assessment tools are often deficient in assisting design for sustainable manufacturing efforts. Integrating an improved assessment method into a decision support framework will provide a means for designers and engineers to better understand the impacts of their decisions. A unit process modeling-based sustainability assessment method is presented...
Sustainability has been the focus of intense discussions over the past two decades, with topics around the entire product life cycle. In the manufacturing phase, research has been focused solely on environmental impact assessment or environmental impact and cost analysis in its assessment of sustainability. However, few efforts have investigated...
The objective of this study is to complete life cycle inventories (LCI) for laminated veneer lumber (LVL) and composite I-joist (I-joist) production in the two main forest products producing regions in the U.S., the Pacific Northwest (PNW) and Southeast (SE). LVL and I-joists are composite wood building materials that are...
The research involved development of two ecological
simulation models to explain the complex dimensionality of
chinook salmon (Oncorhynchus tshawytscha) life history
structure (represented by the age composition of the
spawning stock) and management difficulties entailed in the
complexity.
Since different sizes of chinook salmon are thought to
adapt differently to...
The developmental milestones of Sustainability are consistent with the post-normal versus traditional science, where transdisciplinary and policy/action research are among the important approaches to be added to traditional analysis. This shift requires a new perspective to look at the problem at hand: we are no longer considering a group of...

44. Probability of Differences in LifeCycle Impacts of Albany vs. Sisters Buildings
The growth, size and age composition, mortality and reproduction of darkblotched rockfish (Sebastes crameri) were examined using fishery data and analysis of fish
characteristics for samples collected of f the Oregon coast. A total of 1060 fish, caught by commercial groundfish and shrimp trawlers operating out of Newport, Coos Bay...
