Dynamic Building-To-Grid Integration Through Combined Building System Resources For Frequency Regulation Service, Peng Zhao Oct 2015

Dynamic Building-To-Grid Integration Through Combined Building System Resources For Frequency Regulation Service, Peng Zhao

Civil Engineering Graduate Theses & Dissertations

Frequency regulation (FR) is the electric grid service responsible for maintaining the system frequency at its nominal value of 60 Hz in the United States - an indicator of energy balance on the grid. In cases of mismatch between power supply and demand, frequency regulation resources either on the generation or the demand side, responding rapidly to restore system frequency to its nominal value. Due to the limited responsiveness of electric generators, fast and accurate demand side resources (DSR) have recently been encouraged to participate in frequency regulation. The tested DSR's include flywheels and battery banks. However, high initial equipment ...


Thermal Performance And Design Guidelines Of Thermo-Active Foundations, Byung Chang Kwag Jul 2015

Thermal Performance And Design Guidelines Of Thermo-Active Foundations, Byung Chang Kwag

Civil Engineering Graduate Theses & Dissertations

A thermo-active foundation system can be a cost-effective technology to utilize ground thermal energy to heat and cool buildings. Indeed, thermo-active foundations, also known as thermal piles, integrate heat exchangers with the foundation elements and thus eliminate the need of drilling deep boreholes typically required by the conventional ground source heat pumps. In order to properly design thermo-active foundation systems, their thermal performance under various operating and climatic conditions are evaluated as part of this study using detailed modeling and simulation analyses. In particular, a transient three-dimensional finite difference numerical model has been developed and validated to analyze thermal performances ...


Theory And Testing Of An Energy Signal Tool: An Application Of Building Energy Performance Monitoring, Eric David Rodio Boxer Apr 2015

Theory And Testing Of An Energy Signal Tool: An Application Of Building Energy Performance Monitoring, Eric David Rodio Boxer

Civil Engineering Graduate Theses & Dissertations

There is a growing amount of data being collected from commercial buildings that quantifies their energy use. Very few facilities managers have the means to transform this data to determine how the building is performing compared to expectations. Performance benchmarking of buildings can be used to draw this comparison, but first a benchmark must be established. Many tools exist for equipment fault detection diagnostics (FDD), but FDD alarms do not indicate fault severity. Other tools exist for rapid peer-benchmarking of energy performance, but statistically meaningful comparison groups are small. An Energy Signal Tool is proposed as a way to self-benchmark ...


Development And Application Of A Numerical Framework For Improving Building Foundation Heat Transfer Calculations, Nathanael John Frothingham Kruis Apr 2015

Development And Application Of A Numerical Framework For Improving Building Foundation Heat Transfer Calculations, Nathanael John Frothingham Kruis

Civil Engineering Graduate Theses & Dissertations

Heat transfer from building foundations varies significantly in all three spatial dimensions and has important dynamic effects at all timescales, from one hour to several years. With the additional consideration of moisture transport, ground freezing, evapotranspiration, and other physical phenomena, the estimation of foundation heat transfer becomes increasingly sophisticated and computationally intensive to the point where accuracy must be compromised for reasonable computation time. The tools currently available to calculate foundation heat transfer are often either too limited in their capabilities to draw meaningful conclusions or too sophisticated to use in common practices.

This work presents Kiva, a new foundation ...


Alternate Possibilities: Reimagining The Rothko Chapel, Katie Lee Kisiel Jan 2015

Alternate Possibilities: Reimagining The Rothko Chapel, Katie Lee Kisiel

Art History Theses & Dissertations

The Rothko Chapel in Houston, Texas, has long been recognized as a spiritual landmark and symbol of American postwar modern art. Blurring the boundaries between what is commonly considered sacred and secular, the Rothko Chapel functions as a space for non-denominational worship, private contemplation and meditation, a center for civic action, and as a showcase of the late work of Abstract Expressionist painter, Mark Rothko. The fourteen massive paintings that adorn the chapel space are renowned for their dark and ominous shades of maroon and black. What most visitors to the site do not know, there are six additional panels ...


Incorporating Deeply Uncertain Factors Into The Many Objective Search Process To Improve Adaptation To Environmental Change, Abigail Ashley Watson Jan 2015

Incorporating Deeply Uncertain Factors Into The Many Objective Search Process To Improve Adaptation To Environmental Change, Abigail Ashley Watson

Civil Engineering Graduate Theses & Dissertations

Deep uncertainty refers to situations in which decision makers do not know, or cannot agree upon, the full suite of risks within a planning problem. This thesis reviews frameworks proposed for planning under deep uncertainty. One framework, Many Objective Robust Decision Making (MORDM), combines two techniques: evolutionary algorithm search used to optimize planning alternatives and robust decision making used to sample performance over many plausible factors and choose a robust solution.

We present a methodology that modifies the uncertain input selected within the MOEA search process. Using a case study of water planning in the Lower Rio Grande Valley (LRGV ...


Neo-Traditional Town Centers And Residential Travel Behavior: Effect Of Retail Composition, Sung Won Han Jan 2015

Neo-Traditional Town Centers And Residential Travel Behavior: Effect Of Retail Composition, Sung Won Han

Undergraduate Honors Theses

Neo-traditional developments are often comprised of mix-use neighborhoods with a town center that acts as the central commercial district that is easily accessible to the surrounding residents without a car. This paper investigates the reality of walking and biking in two such neo-traditional developments in Colorado. I compared frequency and purpose of non-car trips in two neighborhoods whose local town centers differ in retail composition. The first town center, Belmar, has a higher composition of comparison goods and services such as clothing, apparel, and other comparison goods. The second, East 29th Avenue Town Center, has a higher composition of ...


Innovations For A Campground Water System: A Biomimicry Approach, Courtney Young Jan 2015

Innovations For A Campground Water System: A Biomimicry Approach, Courtney Young

Undergraduate Honors Theses

I have studied the forms of mycorrhizae and xerophytes to gain inspiration for a water system upgrade. This process of emulating natural forms and strategies is called biomimicry. The U.S. Forest Service is in the preliminary stages of an upgrade for an aging water system at the Prospector Campground in the White River National Forest. Forest Service engineers and designers will use my research as they redesign this system.

I looked at over twenty plants to find adaptations that helped manage water efficiently. I chose to study mycorrhizae and xerophytes because of their wide range and prevalence.

Mycorrhiza is ...


Adaptive Water Management: Alternatives To Close The Supply-Demand Gap In The Northern Colorado Water Conservancy District, Colin Mayberry Jan 2015

Adaptive Water Management: Alternatives To Close The Supply-Demand Gap In The Northern Colorado Water Conservancy District, Colin Mayberry

Undergraduate Honors Theses

Population growth and climate change present water providers with management challenges to maintaining the supply, affordability, and reliability of water resources. In the Northern Colorado Water Conservancy District (Northern Water), population growth poses a 110,000 acre-feet supply-demand gap by the year 2050. Moreover, climatic shifts will simultaneously shift the timing, type, and distribution of expected precipitation. Predict-and-control strategies and traditional agricultural-municipal water transfers are not well-suited to manage water resources in a future dominated by uncertainties. This thesis proposes an adaptive management strategy for the Northern Colorado Water Conservancy District (Northern Water). It presents a novel approach to water ...


The True Cost Of Sips: A Comprehensive Tool For Comparing The Price Of Residential Structural Insulated Panel And Stick Frame Construction, Adam Meis Jan 2015

The True Cost Of Sips: A Comprehensive Tool For Comparing The Price Of Residential Structural Insulated Panel And Stick Frame Construction, Adam Meis

Undergraduate Honors Theses

Increasing the quality of a home generally increases the cost of construction; however, Structural Insulated Panels (SIPs) illustrate one innovation that may be able to break this rule. Can a smallscale home that is stronger and more energy efficient be built in less time and with less construction waste for the same lifespan cost as traditional stickframe construction? Small scale residential construction does not benefit from an economy of scale that helps reduce the cost of SIPs in larger homes, this study assesses whether costbased design decisions can offset the monetary savings from this economy of scale. This study determines ...


Gentrification In The Neoliberal World Order: A Study Of Urban Change In The River North District Of Denver, Colorado, Laura Conway Jan 2015

Gentrification In The Neoliberal World Order: A Study Of Urban Change In The River North District Of Denver, Colorado, Laura Conway

Undergraduate Honors Theses

The River North Arts district in Denver, Colorado has undergone a rapid transformation in the previous two years. I claim that the transformations are not the normal development of a thriving city but instead a neoliberal reimagining of the cityscape. The literature of gentrification was studied in this thesis to synthesize an understanding of gentrification as a neoliberal urban strategy. Subsequently I connected the locality of River North to the larger processes of neoliberal place making through an aesthetic reading, study of maps, and quantitative study of tax assessment data.

Playground: How Ground Surface Materials Influence Children’S Activities In Public Playgrounds, Elizabeth Seaver

Undergraduate Honors Theses

The rise in childhood obesity levels over the last few decades has brought increased attention to public playgrounds as an opportunity to promote healthy physical activity in children. The design of public playgrounds is now viewed as a factor that significantly influences children’s levels of activity that take place in that location. One crucial aspect of playground design is the use of different ground surface materials and how they promote either active or sedentary behavior. This investigation aimed to understand how ground surfaces influence physical activity levels in children and to determine what types of ground materials are the ...


Analysis For Intervention: The Contribution Of Existing Ecologies To The Design Of Place-Based Urban Landscapes, Erin Hauer Jan 2015

Analysis For Intervention: The Contribution Of Existing Ecologies To The Design Of Place-Based Urban Landscapes, Erin Hauer

Undergraduate Honors Theses

Conventional urban growth tends to happen irrespective of environmental context, causing the degradation of ecologically functional and diverse landscapes. This trend separates people from native ecological processes and the inherent benefits they provide (McHarg 1969). Urban systems become unsustainable by failing to incorporate the economic, cultural and ecological values of natural features, relying instead on outsourced energy and high-maintenance infrastructure. In contrast, concepts of ecologically supportive landscapes inspire the design and growth of cities in alignment with natural features. Recognizing the value that increased green space has for the improvement of urban ecologies, this thesis focuses on the restoration of ...


Mod Food: Design Of A Semi-Permanent Modular Food System For Educational Innovation, Margaret Fryke Jan 2015

Mod Food: Design Of A Semi-Permanent Modular Food System For Educational Innovation, Margaret Fryke

Undergraduate Honors Theses

Food is the one consistent variable between cultures and communities that unites people. In the last 80 years, as a result of the shift from locally owned family farms to the industrial scale production of cash crops, consumers have become isolated and alienated from where food comes from and how it is grown (Ferdman, 2014) This lack of understanding is due to an absence of education about food production, raising the question: How can food production be reimagined and presented in a way that is eye catching, promotes a healthy diet, and fosters an excitement about and fundamental understanding of ...
