Evaluating The Energy And Carbon Footprint Of Water Conveyance System And Future Water Supply Options For Las Vegas, Nevada, Eleeja Shrestha

UNLV Theses, Dissertations, Professional Papers, and Capstones

Water production requires the use of energy to transport water from distant locations, pump groundwater from deep aquifers and treat water to meet stringent drinking water and wastewater regulations. Energy production based on its source involves the emission of greenhouse gases also known as carbon footprint, which is the leading cause of global warming and climate change. Because of growing concerns of global warming due to these emissions, water providers are required to analyze the energy and associated carbon footprint of existing water production facilities and future water supply options. A system dynamics model is developed to estimate the energy …

An Investigation Of Sustainable Environmental Practices And Consumer Attitudes & Behaviors Toward Hotel Bathroom Amenities, Edward James Bobbett

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the 1980s hotel operators became concerned with greening and sustainability. It was at this time the hospitality industry began focusing on energy efficiency and the sustainable development of tourism (Chan & Lam, 2001; Welford, Ytterhus, & Eligh, 1999). Since then, a global trend has emerged as hotels introduce programs to reduce the amount of resources used and the overall environmental impact they have on the planet, or their carbon footprint. The hospitality industry has introduced programs such as recycling in both the front and back of the house, energy-efficient lighting, towel re-use programs, linen exchange programs, Green Certifications, and …

Wind Flow Modeling For Wind Energy Analysis Of The Nellis Dunes Area In Nevada, Upendra Rangegowda

UNLV Theses, Dissertations, Professional Papers, and Capstones

A wind energy analysis of the Nellis Dunes area in Nevada was conducted. A DEM file which contains the elevation data was used to generate the surface model and to create a 3-D mesh of the region. Local meteorological tower data collected for a period of one year was used to generate the diagnostic initial wind fields. Upper level wind fields were created using a surface boundary layer technique along with linear interpolation of the tower level wind fields. The vertical components of the velocities were adjusted using the equation of continuity. Mass consistent 3-D wind fields were then calculated …

Perception Of Ecological Risk To Water Environments And How It Affects Water Consumption And Water Resource Management In Southern Nevada, Tanju Kiriscioglu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Climate is harsh in southern Nevada where there is (and has been) a drought alert in effect for over a decade now (Kerr, 2007; Southern Nevada Water Authority, 2009). Las Vegas Valley is a major center of population in the region (1.9 million people), receiving only 4.5 inches of average annual precipitation yet in need of securing more water resources in the near future (SNWA, 2009). Water resource management in southern Nevada is a challenge, especially when 90% of the area’s water needs are met by a single source, the Colorado River, the flow rates of which have been in …

Earthy Bride, Melissa S. Foerster

UNLV Theses, Dissertations, Professional Papers, and Capstones

There are nearly 2.5 million couples getting married in the United States each year (Harrison, 2008, pg. xi). That breaks down to more than 6,300 weddings in a single day. The average wedding in the United States “produces 63 tones of CO2 and 400-600 pounds of trash” and therefore, newlyweds are creating over 3,500,000 pounds of trash in a single at their weddings (Harrison, 2009, ¶ 2)! The green movement is on the rise and wedding industry needs to implement it to meet new demands. In order to do people need to be informed of the importance, benefits and savings …

An Exploratory Study On Energy Consumption Of Energy Star And Non-Energy Star Homes, Prajakta Kulkarni

UNLV Theses, Dissertations, Professional Papers, and Capstones

The reduction of energy consumption is one of the economic necessities in the United States due to depleting energy sources in the world. The construction industry is stepping forward to reduce the energy consumption of buildings by efficient designs or by constructing buildings with energy efficient materials and features. In 1992, the U.S. Environmental Protection Agency (EPA) and Department of Energy (DOE) introduced the Energy Star Program to promote energy efficient products with the same or improved services. According to the EPA, Energy Star homes, which use these products, will consume 20 to 30 percent less energy than non-Energy Star …

The Integration Of Biomimicry Into A Built Environment Design Process Model: An Alternative Approach Towards Hydro-Infrastructure, Timothy Lee Albertson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Current methods and processes that support the planning, design and construction of a sustainable built environment include ambiguous principles (Roseland 2000), lack feedback loops (Van Bueren and Jong 2007) and lack a common language between disciplines (Brandon et al 1997). As a result of 3.8 billion years of "research and development" (evolution), nature provides a set of design blueprints that may be used to guide us to create elegant, sustainable, and innovative designs for human technologies (Benyus 1997). The field of biomimicry analyzes nature's best ideas and adapts them for human use (Benyus 1997). The built environment could benefit from …

The Impact Of Individual Decision Making On Campus Sustainability Initiatives, Aurali Ella Dade

UNLV Theses, Dissertations, Professional Papers, and Capstones

Institutions of Higher Education (IHEs) have increasingly committed to become more sustainable in recent years. Despite this commitment, academic publications in the sustainability field assert that progress has been slower at IHEs than expected and that most IHEs have found sustainability initiatives difficult to implement. Comprehensive sustainability initiatives require cooperation from a broad set of constituents with diverse and sometimes conflicting goals. Creating a sustainable IHE also requires changes in both physical infrastructure and individual behavior. Any number of institutional factors can advance or limit progress towards these objectives.

Previous investigations have assessed individual case studies, compared IHEs in a …

Assessing The Effect Of Simulation Models On Systems Learning In An Introductory Environmental Science Course, Heather J. Skaza

UNLV Theses, Dissertations, Professional Papers, and Capstones

While there is plenty of anecdotal evidence within the systems dynamics community supporting the use of systems simulations in the classroom to improve student understanding, there is little published, controlled, experimental research. This paper describes the results of a paired experiment testing the effect of using system dynamics simulations to increase systems understanding in an introductory environmental science course. We believed that the students using the systems simulations would demonstrate a greater systemic understanding of environmental issues than those who did not.

We conducted an experiment during the fall semester of 2009, with 304 students enrolled in four sections of …
