Covid-10, Healthcare Interior Design + Provider Experience - How Does Your Space Work For You?, Ruth E.P. Deibler
Covid-10, Healthcare Interior Design + Provider Experience - How Does Your Space Work For You?, Ruth E.P. Deibler
Graduate Research Posters
The lack of research on healthcare staff experience and interior design of the spaces they work in is evident. A focus on staff perspective is needed, particularly staff who navigated the COVID-19 pandemic. This research seeks to capture those stories to develop further research in order to improve staff experience. The initial phase of this mixed-methods approach is a survey. Hypothetically, by placing providers at the center of qualitative research related to healthcare interior design, we can better understand existing healthcare spaces. Ideally, we can develop additional evidence-based, human-centered solutions to transform interior environments in healthcare.

Environmental Justice In Little Village: A Case For Reforming Chicago’S Zoning Law, Charles Isaacs
Environmental Justice In Little Village: A Case For Reforming Chicago’S Zoning Law, Charles Isaacs
Northwestern Journal of Law & Social Policy
Chicago’s Little Village community bears the heavy burden of environmental injustice and racism. The residents are mostly immigrants and people of color who live with low levels of income, limited access to healthcare, and disproportionate levels of dangerous air pollution. Before its retirement, Little Village’s Crawford coal-burning power plant was the lead source of air pollution, contributing to 41 deaths, 550 emergency room visits, and 2,800 asthma attacks per year. After the plant’s retirement, community members wanted a say on the future use of the lot, only to be closed out when a corporation, Hilco Redevelopment Partners, bought the lot …

By considering climatic factors relevant to the region, suggestions for relevant eco-friendly practices can be made available to homeowners and renters alike. We will research green living practices used in other countries with similar climatic factors …
Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender
Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender
Student Theses 2015-Present
This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Abstract
Aquaponics, a type of urban agriculture, shows potential to produce large amounts of food with little water and land requirements. Thus, aquaponics could help address the issue of feeding the growing worldwide population. However, multiple challenges, both technical and economical, are associated with aquaponics, making large-scale implementation of these systems difficult – these systems can require tremendous amounts of energy. This study sought to determine the most efficient types grow lights in aquaponics systems by comparing the growth rates of yellow lantern chilies (Capsicum chinense) when grown under four different types of growth lights: light-emitting diode (LED), …
Sustainable Architecture Design: Environmental And Economic Benefits, Michael Babcock
Sustainable Architecture Design: Environmental And Economic Benefits, Michael Babcock
Senior Honors Theses
This thesis examines the movement of environmentalism, and its impact on architecture and construction. During an interview with a professional architect, a basis for research of sustainable design was devised, when he explained that “good” architecture attempts to holistically integrate the external and built environment. Presently, the main measurement for sustainability is energy efficiency. Therefore, architects constantly implement new technology in an attempt to unify both the external and built environment in an energy efficient manner. Furthermore, this thesis provides an environmental and financial cost analysis of implementing sustainable design and build. Research shows that the life cycle and up-front …

Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson
Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson
Master's Theses
Packed-bed digesters are an alternative to covered lagoon digesters for methane production and anaerobic treatment of dilute wastewaters such as dairy barn flush water. The physical media of packed-beds retain biofilms, often allowing increased treatment rates. Previous studies have evaluated several types of media for digestion of dilute wastewaters, but cost and media fouling have setback commercial development. A major operational cost has been effluent recirculation pumping.
In the present effort, a novel approach to anaerobic digestion of flush dairy water was developed at pilot-scale: broken walnut shells were used as a low-cost packed-bed medium and effluent recirculation was replaced …

Issue Brief: Auditing Your Town's Development Code For Barriers To Sustainable Water Management, New England Environmental Finance Center
Sustainable Communities Capacity Building
This issue brief is intended for town officials who want to understand how development regulations in their community affect local water resources. Municipal development codes – the set of regulations that control the built environment – can have a great influence on the availability of clean and healthy water for drinking, recreation, and commercial uses. This in turn affects the community’s social, environmental, and economic vitality.
Comprehensive plans, zoning codes, and building standards are just a few examples of regulations that intentionally or unintentionally regulate the way water is transported, collected and absorbed. Regulations that produce dispersed development or large …
Financing Public Solar Projects: California Public Jurisdictions' Experiences In Acquiring And Financing Solar Photovoltaic Installations, Dana M.C. Hoffman
Financing Public Solar Projects: California Public Jurisdictions' Experiences In Acquiring And Financing Solar Photovoltaic Installations, Dana M.C. Hoffman
Master's Theses
More efficient technologies, state laws as well as environmental, social, and political pressures have all contributed to placing solar acquisition on the agenda for California’s public entities over the last half decade. But a key question for these frequently cash-strapped jurisdictions is how to utilize public dollars and lands, and how to leverage incentives to obtain solar PVs. As an alternative to outright purchase, a promising financing option made available to jurisdictions in recent years is ownership by a third party, usually the solar company, including various forms of Power Purchase Agreements (PPA’s) and leasing. Due in part to state …

Mathematical Modelling Of A Low Approach Evaporative Cooling Process For Space Cooling In Buildings, Medhi Nasrabadi, Donal Finn, Ben Costelloe
Mathematical Modelling Of A Low Approach Evaporative Cooling Process For Space Cooling In Buildings, Medhi Nasrabadi, Donal Finn, Ben Costelloe
Conference Papers
This paper describes a mathematical model of a low approach open evaporative cooling tower for the production of high temperature indirect cooling water (14-16°C) for use in building radiant cooling and displacement ventilation systems. There are several potential approaches to model evaporative cooling, including: the Poppe method, the Merkel method and the effectiveness-NTU (ε-NTU) method. A common assumption, applied to the Merkel and ε-NTU methods, is that the effect of change in tower water mass flow rate due to evaporation is ignored, which results in a simpler model with reduced computational requirements, but with somewhat decreasedaccuracy. In this paper, a …
