A Comparative Study On The Design Typology Of Dense, High-Rise Housing, Nikita Mansinghani
Honors Program: Senior Projects (Public)
The three case studies are multi-unit residential buildings located in three vastly different European cities and designed in different times periods of architectural transformations and technology help us understand the value and development of these units and the significance of them in the future design typologies. The understanding of housing complex has been occupied with the exercise of control as a design tool for demarcating variation to further the purpose of housing and shift in approaches from typical architecture to non-standard creative practices, this article focuses on three precedents: the Unite de habitation, VM houses and The Whale. The three …

Abstract
Is it true that we solve problem using techniques in form of formula? Mathematical formulas can be derived through thinking of a problem or situation. Research has shown that we can create formulas by applying theoretical, technical, and applied knowledge. The knowledge derives from brainstorming and actual experience can be represented by formulas. It is intended that this research article is geared by an audience of average knowledge level of solving mathematics and scientific intricacies. This work details an introductory level of simple, at times complex problems in a mathematical epidermis and computability and solvability in a Computer Science. …
A Vernacular For Lincoln, Nebraska, Austin Riggins
A Vernacular For Lincoln, Nebraska, Austin Riggins
Honors Program: Senior Projects (Public)
The contemporary vernacular architecture in the United States is a product of industrialization and globalization. One homogenous, mass produced vernacular has dominated nationwide and overshadowed the unique, contextual, and regional designs of the past. While the contemporary, industrialized vernacular has led to increases in the quality of life for many in the developed world, it has also left in its wake a homogenous and placeless environment devoid of environmental sensitivity or cultural references. There is a need for a set of new vernaculars that embrace modern building technologies while simultaneously responding more directly to local climatic needs and facilitating a …
Analyzation Of Sandpit Lakes In Grand Island, Nebraska, Olena Yarmolyuk, Morgan Davis
Analyzation Of Sandpit Lakes In Grand Island, Nebraska, Olena Yarmolyuk, Morgan Davis
Architecture Program: Student Creative Activity
The oxford dictionary defines “dichotomy” as, “noun: a division or contrast between two things that are or are represented as being opposed or entirely different.” In the context of Grand Island, Nebraska, a dichotomy exists in the development of housing. In the 1900s, sand quarrying began along the railroad in Grand Island. When the sand was dredged up from these quarries, the floodplain began to fill in holes over 5 feet deep, creating man-made lakes. As these lakes grew the sand could no longer be quarried, recreation and housing began to develop on their shores. The housing developments, in particular, …
A Generic Benchmark For A Mini-Split Heat Pump System, Yuchen Wang
A Generic Benchmark For A Mini-Split Heat Pump System, Yuchen Wang
Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research
Heating, Ventilation, and Air Conditioning (HVAC) accounts for half of the building energy consumption in the U.S where Mini-Split Heat Pumps (MSHPs) are an emerging type of HVAC system. Their utilization has greatly increased by 34% from 2009 to 2013 and high potential EER is recognized for MSHPs. However, there is limited research involving MSHPs systems, and there is no generic benchmark for system testing and modeling. The available simulation tools such as VapCyc, GreatLab, and CYCLE_D are either too complicated, difficult to access, or not freely available. Therefore, an accurate and public share generic benchmark is essential and will …
The Effects Of Tones In Noise On Human Annoyance And Performance, Joonhee Lee
The Effects Of Tones In Noise On Human Annoyance And Performance, Joonhee Lee
Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research
Building mechanical equipment often generates prominent tones because most systems include rotating parts like fans and pumps. These tonal noises can cause unpleasant user experiences in spaces and, in turn, lead to increased complaints by building occupants. Currently, architectural engineers can apply the noise criteria guidelines in standards or publications to achieve acceptable noise conditions for assorted types of spaces. However, these criteria do not apply well if the noise contains perceptible tones. The annoyance thresholds experienced by the general population with regards to the degree of tones in noise is a significant piece of knowledge that has not been …
Case Study Of Quantifying Energy Loss Through Ceiling-Attic Recessed Lighting Fixtures Through 3d Numerical Simulation, Ri Na, Shengmao Lin, Zhigang Shen, Linxia Gu
Case Study Of Quantifying Energy Loss Through Ceiling-Attic Recessed Lighting Fixtures Through 3d Numerical Simulation, Ri Na, Shengmao Lin, Zhigang Shen, Linxia Gu
Durham School of Architectural Engineering and Construction: Faculty Publications
Air leakage through improperly installed recessed lighting fixtures has been identified as a common issue causing extra energy consumption of residential buildings. However, little quantitative study was found in this area. In this paper, a preliminary evaluation of the magnitude of such energy loss was conducted by numerical simulations using 3 dimensional transient computational fluid dynamics (CFD) model. A typical layout of recessed lighting fixtures was used in this case study with boundary conditions in four different seasons, which were obtained from past measured roof/attic temperature data sets. The results of the numerical simulations indicate that leakage of recessed lighting …
Ventilation Rates And Airflow Pathways In Patient Rooms: A Case Study Of Bioaerosol Containment And Removal, Ehsan S. Mousavi, Kevin R. Grosskopf
Ventilation Rates And Airflow Pathways In Patient Rooms: A Case Study Of Bioaerosol Containment And Removal, Ehsan S. Mousavi, Kevin R. Grosskopf
Durham School of Architectural Engineering and Construction: Faculty Publications
Most studies on the transmission of infectious airborne disease have focused on patient room air changes per hour (ACH) and how ACH provides pathogen dilution and removal. The logical but mostly unproven premise is that greater air change rates reduce the concentration of infectious particles and thus, the probability of airborne disease transmission. Recently, a growing body of research suggests pathways between pathogenic source (patient) and control (exhaust) may be the dominant environmental factor. While increases in airborne disease transmission have been associated with ventilation rates below 2 ACH, comparatively less data are available to quantify the benefits of higher …

The Earth All Around Us: Selected Building Stone In Lincoln, Nebraska. A Walking Tour, William J. Wayne
Department of Earth and Atmospheric Sciences: Faculty Publications
Stone has been a primary building material for millennia. Cities, therefore, are treasure troves of earth materials. A wide variety of stones from many places are used for walls, as foundations to support entire buildings, as trim, and more recently as cladding (facing, an overlay). The Earth science teacher can find, in the limited space of an urban environment, a superb collection of stones with which to introduce students to these materials. The surfaces of stones on the outsides of buildings illustrate the durability and the vulnerability of each kind of stone to the local climate. And the history of …
