Industry-Experienced Graduate Student Program: Innovative Collaboration In Architectural Engineering At The University Of Nebraska–Lincoln, Clarence E. Waters, Steve Alvine, Michelle L. Eble-Hankins Jan 2011

Industry-Experienced Graduate Student Program: Innovative Collaboration In Architectural Engineering At The University Of Nebraska–Lincoln, Clarence E. Waters, Steve Alvine, Michelle L. Eble-Hankins

Durham School of Architectural Engineering and Construction: Faculty Publications

In 2001, the Architectural Engineering Department at the University of Nebraska–Lincoln, along with industry partners, established an industry-experienced graduate student program. The program was developed to bring experienced design professionals to collaborate with the industry while pursuing a Ph.D. in architectural engineering. This program is designed to be mutually beneficial to industry partners, -graduate students, the University of Nebraska–Lincoln Architectural Engineering Department, and the building industry at large. The first doctoral candidate in the program graduated, and significant collaborative work was completed for the industry partner. All parties to this initial offering are pleased with the outcome and believe the …


Material And Energy Flow Analysis Of The Irish Construction Sector, Rachel Woodward Jan 2011

Material And Energy Flow Analysis Of The Irish Construction Sector, Rachel Woodward

Theses

A national flow model for concrete was developed using the framework of material and energy flow analysis. Using this framework, the Irish concrete material and energy cycles for the year 2007 were constructed by firstly analysing the material life cycle of concrete which consists of the three phases of production (including extraction of raw materials and manufacture of cement), usage into stock (ready-mix and other concrete products), and waste management. In this year, approximately 35Mt of raw materials were extracted to produce both 5Mt of cement and 33Mt of concrete, with 4.5Mt of cement going into the production of concrete. …

Culvert Material Cost Comparison, New England Environmental Finance Center Nov 2010

Culvert Material Cost Comparison, New England Environmental Finance Center

Water

The following tables provide a detailed look at the role that culvert material and culvert diameter play in the overall cost of a culvert replacement project.


Culvert Material Cost Comparison, New England Environmental Finance Center Nov 2010

Culvert Material Cost Comparison, New England Environmental Finance Center

Economics and Finance

The following tables provide a detailed look at the role that culvert material and culvert diameter play in the overall cost of a culvert replacement project. Table 1 displays the cost per foot purchase price arranged by diameter size for the various culvert materials that are currently available. Table 2 displays the average additional culvert pipe material cost (increased cost to upsize minus original in-kind replacement cost) that would be incurred when upsizing a given diameter of culvert with a 50 foot length by factors of: 200%, 250% and 300%.

Construction Cost Models, Barry Dikeman Aug 2010

Construction Cost Models, Barry Dikeman

Economics and Finance

The following are a series of cost estimate models similar in format to a typical engineer’s estimate that were developed in support of our financial impact assessment report for LD 1725. The models us current material costs, labor costs, and equipment costs for the region to provide a comparative cost analysis of seven culvert replacement scenarios. The models provide information about what the cost impact of LD 1725 would be for typical culvert replacements in Maine. However, due to the inherent restrictions of the cost modeling framework we were not able to include the abundance of variables that would be …

Active Noise Barrier Minimizing Pressure Gradient, Carl Hart, Siu-Kit Lau Jan 2010

Active Noise Barrier Minimizing Pressure Gradient, Carl Hart, Siu-Kit Lau

Durham School of Architectural Engineering and Construction: Faculty Publications

Minimization of the sound pressure field within the shadow zone of a noise barrier is achieved by reducing the pressure gradient along a line, at the top of a barrier, via active noise control. The noise control effectiveness of a barrier is increased by this strategy, especially for specific system configurations. The proposed method was evaluated by numerical simulation. Results indicate that system orientation has little effect on minimizing the pressure gradient at the top of the barrier when the error sensors are invisible to the primary noise disturbance. Highly effective control within the shadow zone and close to the …


Noise Propagation Through Open Windows Of Finite Depth Into An Enclosure, Caleb Sieck, Siu-Kit Lau Jan 2010

Noise Propagation Through Open Windows Of Finite Depth Into An Enclosure, Caleb Sieck, Siu-Kit Lau

Durham School of Architectural Engineering and Construction: Faculty Publications

Predicting the insertion loss of an opening backed with an enclosed space is important for building noise control. Recent research in sound transmission through apertures of finite depth in infinite rigid baffles has included the effects of propagating and evanescent modes within the aperture in order to extend models to higher frequencies. The present study extends the model to the case of the aperture backed by a cavity as opposed to sound radiating into half-space. The role of coupling between the aperture modes, radiation modes, and cavity modes in the transmission was investigated. The results were compared to those of …

Leadership, Libraries, Leed For The Future, Kathryn S. Ames, Greg Heid Jan 2010

Leadership, Libraries, Leed For The Future, Kathryn S. Ames, Greg Heid

Georgia Library Quarterly

The article discusses the use of Leadership in Energy and Environmental Design (LEED) principles in the design of the modern public library. It is stated that an LEED-certified library will have lower costs in energy, systems replacement and maintenance through the use of light-emitting diode (LED) lighting and efficient heating and air conditioning, but that due to special materials, the up-front expense is higher. The inspection of the facility throughout its construction is also noted.

Application Of Pv Panels In Large Multi-Story Buildings, Sara Kayal Jun 2009

Application Of Pv Panels In Large Multi-Story Buildings, Sara Kayal

Master's Theses

Application of PV Panels in Large Multi-Story Buildings Feasibility Study Sara Kayal

The awareness of global warming along with an ever increasing demand for a new source of energy has brought a strong interest in harnessing natural resources such as solar energy. This thesis evaluates the viability of applying photovoltaic (PV) panels in high-rise commercial buildings of around 20 stories. Specifically, the thesis is intended to provide a pre-planning tool during the early design stage for architects and designers who are considering the deployment of PV panels in new multi-story construction.

The first three chapters cover a comprehensive literature review …
