Transportation networks evolved in response to emergent transportation technologies and changing urban land uses. The irregular distribution of transportation systems reinforced patterns of land use development, shaping urban form. Understanding the relationships between transportation and the intensity of land uses allows urban geographers and city planners to explain the urbanization processes, as well as to identify areas historically susceptible to future development. The goal of this research is to develop a quantitative framework for the analysis of the development of urban form …

Cyclist Path Choices Through Shared Space Intersections In England, Allison Boyce Duncan

Dissertations and Theses

In the last several years, there has been growing worldwide interest in making streets safer for all users--pedestrians, cyclists, and motorists. One approach, shared space, is a traffic calming technique as well as urban design concept. This technique strives to fully integrate the roadway into the urban fabric by removing elements such as lane markings, curbs, and traffic signs. By removing these elements and creating a more plaza-like space, these sites become ambiguous and no user group as priority. The technique is relatively new, and the majority of existing research concerns pedestrians only. This mixed methods research focused on six …

The Effects Of Urban Containment Policies On Commuting Patterns, Sung Moon Kwon

Dissertations and Theses

During the past several decades, most U.S. metropolitan areas have experienced strong suburbanization of housing and jobs (i.e., urban sprawl). The sprawl that arises from urban growth has become a big issue in many metropolitan areas in the U.S. In response, there has been increased interest in urban containment policies. There are contrasting views (planning-oriented vs. market-oriented) of urban sprawl and urban containment policies. Planning-oriented scholars asserted the problems of 'geographic sprawl (GS)' and the positive effects of urban containment polices, while market-oriented scholars asserted the problems of 'economic sprawl (ES)' and the negative or negligible effects of urban containment …

Sensible Air To Air Heat Recovery Strategies In A Passive House, Santiago Martin Rodriguez-Anderson

Dissertations and Theses

Due to rising energy costs and concerns about global climate change, high performance buildings are more in demand than ever before. With roughly 20% of the total energy consumption in the United States being devoted to residential use, this sector represents a significant opportunity for future savings. There are many guidelines and standards for reducing building energy consumption. One of the most stringent is the Passive House Standard. The standard requires that that air infiltration is less than or equal to 0.6 air changes per hour at a 50 Pascal pressure difference (ACH 50), annual heating energy is less than …

Whose Urban Forest? The Political Ecology Of Foraging Urban Nontimber Forest Products, Patrick T. Hurley, Marla R. Emery, Rebecca J. Mclain, Melissa R. Poe, Brain Grabbatin, Cari L. Goetcheus

Institute for Sustainable Solutions Publications and Presentations

Drawing on case studies of foraging in Philadelphia, Pennsylvania and Mt. Pleasant, South Carolina, we point to foraging landscapes and practices within diverse urban forest spaces. We examine these spaces in relation to U.S. conservation and development processes and the effects of management and governance on species valued by foragers. These case studies reveal the everyday landscapes of urban foraging and suggest that ideas about what constitutes the suite of appropriate human-environment interactions in the sustainable city are contested and accommodated in diverse ways.

Research-Based Design Initiative

Current standard construction techniques play an increasing role in greenhouse gas emissions, so the need for exploration into alternative methods are a requirement for future products and construction. 47% of the CO2 emissions delivered into our atmosphere are due to building construction and materials. Cross-laminated timber (CLT) and other varied wood products are an emerging, viable source of sustainable, alternative building methods. The presented body of research explains the benefits of utilizing CLT, and other wood products, by expressing their embodied energy calculations and how that is determined by a process known as “Cradle-to-Gate”.

Evolutionary Modeling And Building Energy Efficiency: How Can Building Performance Evaluation Be Integrated Early Into An Ever-Accelerating Design Process?, Portland State University. School Of Architecture

Research-Based Design Initiative

With the increasing demand for energy efficient buildings, designers have begun to face a new challenge- how can performance evaluation be integrated into the ever-accelerating design process? The design and performance evaluation of a building are, in most cases, divorced. The designer will often have to halt, freeze the design, and wait for performance results to filter back. That gap between freezing the design and awaiting results can be weeks. In that time the design may have changed dramatically and the results made useless. In other instances, the final design is submitted to be evaluated, results are received, and critical, …
