UNLV Theses, Dissertations, Professional Papers, and Capstones

This research evaluates the effects of varying thermal properties of windows in

residential energy use for the moderate altitude and 36'N latitude climate of southern

Nevada, which has a distinct cooling season. A selection of windows across different

shading conditions and total window areas were studied using BEopt energy simulation.

Findings demonstrate that for the specific climate, latitude, and altitude of Las Vegas,

Nevada, the most expensive “high performance” windows are not always the best

option in terms of total site energy use, and can be outperformed by properly shaded

less advanced windows. Under certain conditions, shading was found to …

Understanding Urban Sustainability And Quality Of Life: A System Dynamics Approach, Abby Elizabeth Beck

UNLV Theses, Dissertations, Professional Papers, and Capstones

For an urban area to be sustainable, its resources cannot be depleted faster than they can replenish. If an urban area is to provide a high quality of life (QOL), it must offer and maintain an amenity package that satisfies its resident's preferences. Past studies on these topics all have a common thread: sustainability and QOL both pertain to people's relationship to capital. Capital is something that can accumulate and add value to a person or society. If sustainability and QOL are a function of people's relationship with capital, how they use it, deplete it, replenish it and transform it …

Legal Issues In Green Construction, Namrata Shrestha

UNLV Theses, Dissertations, Professional Papers, and Capstones

The most recent "green construction movement", made a significant impact on the design and construction industry in the United States. Organizations such as the American Institute of Architects (AIA) have lobbied governmental entities to provide financial incentives to promote green construction. The green construction community also promotes the notion that a healthier working and living environment is achieved. Due to finical incentives coupled with projected long-term energy cost savings, many owners of new construction are considering green construction as an option. Accompanying the "green construction movement", new kinds of legal issues, particularly relating to green aspects such as certification, energy …

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 …

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 …

Flowing Toward Sustainability: Two Stream Adjudications Analyzed Under The Iad Framework, Nancye Lou Bethurem

UNLV Theses, Dissertations, Professional Papers, and Capstones

One of the most significant problems impacting the western United States today is the lack of naturally occurring water resources, especially during this period of drought and explosive population growth. This has led to intense competition over water use and ownership in the arid and semi-arid regions of the United States. During this period of water resource scarcity, it is extremely important to determine the ownership of water rights in order to implement optimal management systems. Most western states use a system of "general stream adjudications" to make water rights ownership determinations.

General stream adjudications are legal proceedings used to …

Limiting Growth In Las Vegas - A Necessary Growth Strategy For The Twenty-First Century, Cheryl Ann Frassa

UNLV Theses, Dissertations, Professional Papers, and Capstones

Land development in the Las Vegas Valley continues at an unprecedented rate and future growth will no doubt be strongly advocated. Yet, water resources in this desert area are finite, and in the near future, supply will fall short of demand. Plans are underway to supplement the existing supply, and proposals to secure additional sources are under investigation. But there are no guarantees these ambitious endeavors will materialize. In light of the pending water crisis, the pervasive "growth at all cost" policies now dominant in the valley must be abandoned and more realistic land-use policies developed; ones based on the …
