Identification And Characterization Of Fine Particulate Matter Hot Spots On An Urban Arterial Corridor Integrating Probe Vehicle, Traffic And Land Use Data, Katherine Eleanor Bell
Identification And Characterization Of Fine Particulate Matter Hot Spots On An Urban Arterial Corridor Integrating Probe Vehicle, Traffic And Land Use Data, Katherine Eleanor Bell
Dissertations and Theses
The purpose of this study is to explore the use of integrated probe vehicle, traffic and land use data to identify and characterize fine particulate matter (PM[subscript 2.5]) hot spot locations on urban arterial corridors. In addition, a preliminary analysis is conducted to consider volatile organic compound (VOC) hot spot locations. A pollutant hot spot is defined as a location on a corridor in which the mean pollutant concentrations are consistently above the 85th percentile of pollutant concentrations when compared to all locations along the corridor. In order to collect data for this study, an electric vehicle was equipped with …
Skateboarding As Transportation: Findings From An Exploratory Study, Tessa Walker
Skateboarding As Transportation: Findings From An Exploratory Study, Tessa Walker
Dissertations and Theses
In recent decades skateboarding has expanded from recreation into a form of transportation. Skateboarders appear to use roadways much as other non‐motorized modes do. However, there is little academic research on the needs and characteristics of the skateboard as a mode. This research reports demographics, multi‐modal and travel behavior findings, and other data from an exploratory mixed‐methods study of skateboarding as a mode of transportation.
Diffusion Of Energy Efficient Technology In Commercial Buildings: An Analysis Of The Commercial Building Partnerships Program, Chrissi Argyro Antonopoulos
Diffusion Of Energy Efficient Technology In Commercial Buildings: An Analysis Of The Commercial Building Partnerships Program, Chrissi Argyro Antonopoulos
Dissertations and Theses
This study presents findings from survey and interview data investigating replication of green building measures by Commercial Building Partnership (CBP) partners that worked directly with the Pacific Northwest National Laboratory (PNNL). PNNL partnered directly with 12 organizations on new and retrofit construction projects, which represented approximately 28 percent of the entire U.S. Department of Energy (DOE) CBP program. Through a feedback survey mechanism, along with personal interviews, quantitative and qualitative data were gathered relating to replication efforts by each organization. These data were analyzed to provide insight into two primary research areas: 1) CBP partners' replication efforts of green building …
Evaluation Of Phase Change Materials For Cooling In A Super-Insulated Passive House, Jeffrey Stephen Lauck
Evaluation Of Phase Change Materials For Cooling In A Super-Insulated Passive House, Jeffrey Stephen Lauck
Dissertations and Theses
Due to factors such as rising energy costs, diminishing resources, and climate change, the demand for high performance buildings is on the rise. As a result, several new building standards have emerged including the Passive House Standard, a rigorous energy-use standard based on a super-insulated and very tightly sealed building envelope. 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, annual heating energy is less than or equal to 15kWh/m2, and total annual source energy is less than or equal to 120 kWh/m2. A common …
Faulty Measurements And Shaky Tools: An Exploration Into Hazus And The Seismic Vulnerabilities Of Portland, Or, Brittany Ann Brannon
Faulty Measurements And Shaky Tools: An Exploration Into Hazus And The Seismic Vulnerabilities Of Portland, Or, Brittany Ann Brannon
Dissertations and Theses
Events or forces of nature with catastrophic consequences, or "natural disasters," have increased in both frequency and force due to climate change and increased urbanization in climate-sensitive areas. To create capacity to face these dangers, an entity must first quantify the threat and translate scientific knowledge on nature into comprehensible estimates of cost and loss. These estimates equip those at risk with knowledge to enact policy, formulate mitigation plans, raise awareness, and promote preparedness in light of potential destruction. Hazards-United States, or Hazus, is one such tool created by the federal government to estimate loss from a variety of threats, …
Neighborhood Commercial Corridor Change: Portland, Oregon 1990-2010, Kelly Ann Howsley-Glover
Neighborhood Commercial Corridor Change: Portland, Oregon 1990-2010, Kelly Ann Howsley-Glover
Dissertations and Theses
Commercial corridors in neighborhoods experiencing change have been relegated to a footnote in research on residential phenomena. It is taken for granted that the process of change experience by businesses within these neighborhoods mirrors that of the residential change. This assumption is often predicated on the underlying model of invasion succession, suggesting that inmovers displace native populations, whether they are residents or businesses. Analyzing time series data on neighborhood commercial corridor change, research attempted to first test data against the invasion succession model to see if it is an effective framework for analysis. Second, through comparison of case study areas …
Measuring The Effects Of Environmental Certification On Residential Property Values - Evidence From Green Condominiums In Portland, U.S., Xi Yang
Dissertations and Theses
Green building, as an environmentally responsible and resource-efficient product, has emerged in recent decades. Along with the growing interest in green building design and operating practices, a number of green building certification standards and rating systems have been developed by different organizations worldwide. Those rating systems allow government regulators, building professionals, and consumers to embrace green building with confidence. Many recent studies find that LEED and Energy Star certified commercial buildings gain significant rental and sales price premiums and have higher occupancy rates. However, little research has been conducted to measure the market value of certified multi-family residential buildings, for …
Development Of Dynamic Thermal Performance Metrics For Eco-Roof Systems, Seth Sinclair Moody
Development Of Dynamic Thermal Performance Metrics For Eco-Roof Systems, Seth Sinclair Moody
Dissertations and Theses
In order to obtain credit for an eco-roof in building energy load calculations the steady state and time-varying thermal properties (thermal mass with evapotranspiration) must be fully understood. The following study presents results of experimentation and modeling in an effort to develop dynamic thermal mass performance metrics for eco-roof systems. The work is focused on understanding the thermal parameters (foliage & soil) of an eco-roof, further validation of the EnergyPlus Green Roof Module and development of a standardized metric for assessing the time-varying thermal benefits of eco-roof systems that can be applied across building types and climate zones. Eco-roof foliage, …
Public Space And Urban Life: A Spatial Ethnography Of A Portland Plaza, Katrina Leigh Johnston
Public Space And Urban Life: A Spatial Ethnography Of A Portland Plaza, Katrina Leigh Johnston
Dissertations and Theses
The Urban Center Plaza at Portland State University is a high profile place situated in downtown Portland, Oregon. In some ways it is the ideal university plaza providing space for eating, conversing, or limited recreational activity. It is a place that has been studied before, but not in a more in-depth method incorporating quantitative and qualitative analyses. It is also a place that has gone through several stages of development and is the target of many opinions based on casual observations, at times due to these changes. This thesis focuses on an ethnography of place in this particular plaza in …
