Reframing The Narrative: Urban Art, Civil Discourse, And #Optoutside, Natalie Bognanno Jan 2018

Reframing The Narrative: Urban Art, Civil Discourse, And #Optoutside, Natalie Bognanno

Undergraduate Honors Theses

The #OptOutside campaign used by popular lifestyle brand REI promotes the cause people should utilize their time and access to the natural landscapes to participate in outdoor activities. As this idea has become popularized and promoted, communities like Boulder, who maintain similar values of the outdoor lifestyle, have become a symbol for this ideology. But when we apply this narrative to the entire community, including the homeless segment, there exists a divide, where the weight of #OptOutside in a voluntary and recreational sense for everyone, is lost because it does not fit the ideas and values of the homeless population ...

Bricks, Branding, And The Everyday: Defining Greatness At The United Nations Plaza In San Francisco, Georgia Lindsay Jul 2017

Bricks, Branding, And The Everyday: Defining Greatness At The United Nations Plaza In San Francisco, Georgia Lindsay

Program in Environmental Design Faculty Contributions

After over a decade of reports, designs, and public outreach, the United Nations Plaza in San Francisco was dedicated in 1976. Using historical documents such as government reports, design guidelines, letters, meeting minutes, and newspaper articles from archives, I argue that while the construction of the UN Plaza has failed to completely transform the social and economic life of the area, it succeeds in creating a genuinely public space. The history of the UN Plaza can serve both as a cautionary tale for those interested in changing property values purely through changing design, and as a standard of success in ...

A Mathematical Model For Predicting The Carbon Sequestration Potential Of Exposed Ordinary Portland Cement (Opc) Concrete, Adriana Souto Martinez Jan 2017

A Mathematical Model For Predicting The Carbon Sequestration Potential Of Exposed Ordinary Portland Cement (Opc) Concrete, Adriana Souto Martinez

Civil Engineering Graduate Theses & Dissertations

This study concerns the development of a simple mathematical model that calculates the theoretical carbon sequestration potential of exposed ordinary portland cement (OPC) concrete. OPC concrete sequesters non-trivial amounts of carbon dioxide (CO2) via carbonation – a chemical reaction between cement paste and atmospheric CO2. Formulated by the reaction chemistries of cement hydration and carbonation, the model accounts for cement type and content, exposure, time, and type and quantity of supplementary cementitious materials (SCMs). Once validated with data from literature, the model is implemented to investigate the effect of these factors and the influence of compressive strength and geometry, namely surface-area-to-volume ...

Development Of A Simplified Heat And Moisture Transfer Model For Residential Buildings, Joowook Kim Jan 2017

Development Of A Simplified Heat And Moisture Transfer Model For Residential Buildings, Joowook Kim

Civil Engineering Graduate Theses & Dissertations

A large number of building energy simulation programs are used to evaluate indoor conditions and energy performance of buildings. Every building energy modeling tool calculates the heat and moisture exchange among the outdoor environment, the building envelope, and indoor environments as a fundamental component of heating, ventilating, and air conditioning (HVAC) loads. While all tools account for moisture flow through the envelope by infiltration, almost no users calculate moisture diffusion through the envelope or moisture storage in the building due to excessive computation time and unavailable material properties. However, research has shown, and work in this dissertation has confirmed, that ...
