Modeling Passive Solar Distillation Production In Las Vegas, Nevada, Noe I. Santos

UNLV Theses, Dissertations, Professional Papers, and Capstones

A study has been performed to examine the effects of daily weather on the performance of commercial solar distillation basins (solar stills). The objectives of this study were to evaluate the long term performance of solar stills, to instrument two solar stills and record sub-hourly thermal properties, to evaluate existing heat transfer modeling methods for hourly production, and to create new models to predict daily production using experimental distillate production and local weather data by utilizing artificial neural networks, genetic algorithms, and multivariate regression. A system dynamics model was also created to determine the required basin area and storage volume …

Fenestration Studies On Building Energy Using The Facade Evaluation Facility, Wendell Cocina

UNLV Theses, Dissertations, Professional Papers, and Capstones

The project was developed to assess several types of facades and their influence on building energy, mainly focused on windows and other building fenestrations. Requirements for the facility are stated in this paper alongside corresponding solutions. The facility is designed to represent a section of a building façade. Experimenting on a wide range of fenestrations including windows with integrated PV elements was the primary prerequisite. The option of removable façade configurations was used and allowed testing specimens to be changed effortlessly. Instrumentation and data acquisition are discussed including calibration and uncertainty analysis. Investigation of the air conditioning unit was concluded …

Changing Climatic Conditions In The Colorado River Basin: Implications For Water Resources Management In The Las Vegas Valley, Srijana Dawadi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Climate change affects the water available in a region. It also affects the water demand, because of the increase in temperature. A system dynamics model was developed for the Colorado River Basin (CRB), operating at a monthly time scale, to assess the potential impacts of climate change on streamflow in the Colorado River and its subsequent impact on the water resources management in the Las Vegas Valley (LVV). The effect of climate change on streamflow was evaluated using 16 global climate model outputs for 3 emission scenarios, also referenced in the Inter-Governmental Panel on Climate Change Fourth Assessment Report. Risk …

Developing An Employee Training Addendum For A Sustainable Hospitality Operation, Devonne A. Williams

UNLV Theses, Dissertations, Professional Papers, and Capstones

As sustainability has become an important part of everyday life for American consumers, it is important that the hospitality industry do whatever it takes to meet their needs. Consumers expect businesses that they patronize to have policies in place for waste reduction, air and water conservation, and improved air quality and environment. Without the support of the front line employees, however, a hospitality operation has no chance to obtain sustainable success in these arenas. By creating addendums to previously existing employee handbooks, businesses are able to provide their employees with new policies and expectations of sustainable behaviors. This professional paper …

Development Of A Sustainable Water Resource Financing Mathematical Model For Donors And End-Users, Sahar Zavareh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rural villages and underdeveloped communities represent the largest group challenged by poor water supply and sanitation with inequalities in resources to adequately implement potential solutions and even more with their high risk level of financing, funding is particularly challenging for water projects. Innovative financing alone will not eliminate the burdens of rural villages and underdeveloped communities. The purpose of this thesis is to address the lack of sustainable water financing of water projects in rural areas using a novel framework of a mathematical model based on "system dynamics" using optimal feedback control theory to maximize the performance of a water …

Purpose:

The purpose of this study is to see if environmentally friendly practices are a factor for college students when selecting a hotel. Another purpose of this study is to see if students would be willing to spend more for hotels who offer these environmentally friendly practices.

Telework Within The Bureau Of Reclamation Lower Colorado Region Office, Theresa Lee, Lynne Arnold, John Wagner, Elias Samorano, Anita Morgan

UNLV Theses, Dissertations, Professional Papers, and Capstones

A team of researchers from The University of Nevada, Las Vegas were invited by management to observe, assess, and offer recommendations. It was determined by the research team that the first step to improving participation would be to observe the functional telework policy, compare and contrast it with the Department of the Interior standards, and offer recommendations to generate data necessary to develop an updated telework policy by management. The recommendations made by this group include creating an employee eligibility list, tracking actual participation by creating a renewal policy for employees choosing to telework. It is also recommended that a …

Climate Change In Rural Nevada: The Influence Of Vulnerability On Risk Perception And Environmental Behavior, Ahmad Safi

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this research, I examine the impact of vulnerability on risk perception, stated willingness to adopt individual mitigation behavior, and support for climate change mitigation policies. My major research question is, "Does vulnerability to climate change increase risk perception, encourage more energy-efficient individual behavior, and enhance support for climate change mitigation policies?" But to understand the role of vulnerability I also pursue answers to questions regarding its three components: Physical vulnerability; sensitivity and adaptive capacity. I investigate the following sub-questions:

• Do physical vulnerability, and sensitivity to climate change increase risk perception, encourage more energy-efficient individual behavior, and enhance support for …

An Empirical Comparison Of Life Cycle Cost Of Green School Buildings And Non-Green School Buildings, Nitisha Pushpala

UNLV Theses, Dissertations, Professional Papers, and Capstones

One of the major economic concerns today of the world is reduction of energy consumption because of depleting energy sources in the world. The construction sector in the United States is also contributing in reducing the energy consumption and construction cost of the buildings by constructing cost and energy efficient buildings with energy efficient materials and techniques. The U.S Department of Energy introduced the Building Technologies Program that develops techniques, tools and technologies for making buildings more energy efficient. Other private bodies like the Leadership in Energy and Environmental Design (LEED), which is developed by the U.S. Green Building Council …

Planning For Building-Integrated Agriculture In Las Vegas, Robert Vralsted

UNLV Theses, Dissertations, Professional Papers, and Capstones

High food prices, concern about food nutrition and safety, and an awareness of commercial farming's environmental impact have generated a renewed interest in sustainable urban agriculture. Advances in controlled environment agriculture (CEA) have made it possible to grow food virtually anywhere in a much more sustainable manner than traditional field-based agriculture. Locating and planning urban farms using retrofitted existing building stock to maximize food production and ease of distribution in Las Vegas requires consideration of multiple barriers related to geography, economics, and the built environment. Consideration of these factors in the planning process informs the design of a successful BIA …
