Integrated Chiller System Reduce Building Operation And Maintenance Costs In Cold Climates, N. Sheets, Mingsheng Liu

Durham School of Architectural Engineering and Construction: Faculty Publications

Although water-cooled chillers are more energy efficient than air-cooled chillers, a majority of chilled water systems use air-cooled chillers. In cold weather climates, air-cooled chillers are capable of functioning in low ambient temperatures with few operational concerns, where as water-cooled chiller systems must be equipped to prevent cooling tower freezing. The integrated chiller system attempts to take advantage of each chiller’s strengths and eliminate any cold weather operational concerns. An integrated chiller system includes a cooling tower and air-cooled condenser. During the summer, both the cooling tower and air condenser can be operated. In cold weather, the cooling tower is …

Development Of By-Pass Blending Station System, Mingsheng Liu, D. Barnes, K. Bunz, N. Rosnberry

Durham School of Architectural Engineering and Construction: Faculty Publications

A new building blending station system named by-pass blending station (BBS) has been developed to reduce building pump energy consumption in both district heating and cooling systems. Theoretical investigation demonstrated that the BBS can significantly reduce building pump power for a typical cooling system when constant water flow is maintained in the building side. When differential pressure reset is applied in the building side, more pump energy can be saved. The BBS also reduces the pump size and therefore results in lower initial system cost. A case study was also performed and demonstrated 42% of annual chilled water pump energy …

A Simplified Two Dimensional Soil Model For The New Madrid Seismic Zone, Wei Zheng, Ronaldo Luna

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The New Madrid Seismic Zone (NMSZ) is one of the most seismically susceptible areas in United States. Deep alluvial soil deposit of the Mississippi Embayment overlies the NMSZ, which remains a major uncertainty for site response analysis. based on the experiment data, a simple constitutive soil model is developed to take into account the influence of the effective confining pressure on the shear modulus degradation and the viscous damping development in soil, and also the shear strain and the plasticity index. This model is implemented into a two-dimensional finite element code in the time domain. the Rayleigh viscous damping scheme …

Finite Element Modeling Of Guastavino Tiled Arches, Edmond P. Saliklis, S. J. Kurtz, S. V. Furnbach

Architectural Engineering

An investigation of Rafael Guastavino's arches has been conducted by means of finite element modeling and laboratory experimentation. A novel method of modeling laminated masonry tile construction via the finite element method has been devised. This technique takes advantage of the layered shell element features found in commercially available finite element programs. Historical Guastavino tiles have been tested to obtain material properties. These modem techniques have been employed in conjunction with Guastavino's original empirical design criteria to provide a better understanding of these historically significant structures.

Indirect Evaporative Cooling Potential In Air-Water Systems In Temperate Climates, Ben Costelloe, Donal Finn

Articles

Recent developments have prompted a review of evaporative cooling technology as an effective means of cooling modern deep plan buildings. Prominent among these developments is the success of high temperature sensible cooling systems, particularly, chilled ceilings, which require a supply of cooling water at 14–18 °C. Crucial to the success of evaporative cooling technology, as a significant means of cooling in modern applications, is the ability to generate cooling water, in an indirect circuit, at a temperature which closely approaches the ambient adiabatic saturation temperature (AST) or wet bulb temperature (WBT). Recent experimental research has demonstrated that it is technically …

What Reflections Of Eden Do We Find In A Garden?: An Analysis Of Illusionary Constructs That Seek To Establish Identity With The 'Ideal' Garden, Olga Kirov

Theses : Honours

Gardens are retreats that offer sanctuary from the tensions of modern life, Spiritual needs have stirred the Western psyche the most to embellish myths that account for the inconsistency of life. The original myth of the Garden of Eden has represented the ideal paradigm between imperfect nature and human nature, accounting for human frailty and anxious yearnings for a utopian perspective. In attempt to improve human nature, throughout time humans have aspired to transform or improve the natural environment, thus making every garden an image. As an art form, that draws on the past as it looks to the future, …

Web Crippling Of Cold-Formed Steel Beams At End Supports, M. W. Holesapple, Roger A. Laboube

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This investigation focused on the effects of overhang length on the web crippling capacity of cold-formed steel members. the current design recommendations in North America do not provide for an increase in web crippling capacity for end-one-flange loading when an overhang is present beyond the end support. the test specimens used for the investigation were single web C-sections and Z-sections. the current design requirements for end-one-flange web crippling capacity were found to be conservative for overhang lengths ranging from 0.5 h to 1.5 h , where h is the web depth. However, the design practice that permits the application of …

Digital Architecture As Crime Control, Neal K. Katyal

Georgetown Law Faculty Publications and Other Works

This paper explains how theories of realspace architecture inform the prevention of computer crime. Despite the prevalence of the metaphor, architects in realspace and cyberspace have not talked to one another. There is a dearth of literature about digital architecture and crime altogether, and the realspace architectural literature on crime prevention is often far too soft for many software engineers. This paper will suggest the broad brushstrokes of potential design solutions to cybercrime, and in the course of so doing, will pose severe criticisms of the White House's recent proposals on cybersecurity.

The paper begins by introducing four concepts of …

Using Smart Growth Principles For Development In St. Landry Parish, Rebecca L. Scheffler

LSU Master's Theses

Since the end of World War II, many American cities have seen an outward migration from their core into open spaces along the city’s edge. The urban/suburban sprawl phenomenon not only affects urban cores but the rural lands and open spaces surrounding them. As landscape architects, we study humans and their interactions with the environment and have an important position in making informed decisions about issues of sprawl and unmitigated growth in communities. This study was conducted to provide city and parish officials and planning boards with options for beneficial growth in St. Landry Parish, a rural parish in south …

Gateways Into The Atchafalaya: Developing A Framework For Water-Based Recreation In The Atchafalaya Basin Parishes, Steven Joseph Lumpkin

LSU Master's Theses

The term “gateways” has been used in many contexts as a means of providing entry or connection. Gateways are where people congregate to leave a realm of familiarity to one of uncertainty and adventure. They can also mark the entrance into an area of interest. Gateways may have a significant impact on an individual’s impression of a particular destination. This thesis provides arguments for using boating gateways into the Atchafalaya Basin (AB) region as the basis for a recreational framework that encompasses eight parishes. A common theme that exists in all eight AB parishes is their boat launches. They represent …

Sustainable Agriculture And The Red Stick Farmers' Market: An Exploration Of The Use Of Concept In Design, Lawrence Christopher Campany

LSU Master's Theses

This is a treatise on an attempt to translate a concept -- the driving principle of a design in the parlance of the design studios at the Louisiana State University School of Landscape Architecture -- into practice, form and function. If form follows function, as states the oft quoted proverb of design credited to Louis Sullivan, then perhaps as much attention should be given to the design of the function as the form. What this treatise will demonstrate is that function designed around a concept can result in physical manifestations, or forms, of that concept. In this case a concept …

Exedra: Form And Function In The Landscape, Daniel W. Mcelmurray

LSU Master's Theses

This study resulted in the development of design guidelines used to create a contemporary exedra, in relationship to commemoration in the landscape. Through research and field investigation, an assessment of forms, materials, uses and locational characteristics of the exedra provides an understanding of the dynamics of the relationships between the elements of the exedra. By understanding the historical and commemorative nature of the exedra, landscape architects can utilize the form to create freestanding or structurally-integrated exedral forms as a solution to the identified need for the development of human-scale, urban places which commemorate people, places, and events.
