High Fidelity Cfd Modeling Of Natural Ventilation In A Solar House, Mirka Deza, Baskar Ganapathysubramanian, Shan He, Ulrike Passe

Ulrike Passe

Natural ventilation is an important factor in the design of sustainable buildings; it has the potential to improve air quality, while providing thermal comfort at reduced energy costs. Computational fluid dynamics (CFD) simulations provide comprehensive information on the internal flow pattern and can be used as a design tool. The present work offers insight of natural ventilation in a fully functional building, namely, the solar facility Interlock House in Iowa. Ventilation in the house is studied during summer months with some of its furniture included. The results show quantitative agreement between numerical simulations and experiments of vertical temperature profiles for ...


Incorporation Of Future Building Operating Conditions Into The Modeling Of Building–Microclimate Interaction: A Feasibility Approach, Kelly Kalvelage, Ulrike Passe, Caroline Krejci, Michael C. Dorneich 2017 Iowa State University

Incorporation Of Future Building Operating Conditions Into The Modeling Of Building–Microclimate Interaction: A Feasibility Approach, Kelly Kalvelage, Ulrike Passe, Caroline Krejci, Michael C. Dorneich

Ulrike Passe

This paper presents a novel modeling methodology that integrates the near building environmental conditions (or microclimate), whole-building design, and occupant behavior. Accurate predictions of the future building operating conditions lead to designs that serve the building’s purpose – to support occupants’ tasks. This study bridges the gap between human factors and architecture to include physical, cognitive, and organizational systems into building information modeling using future typical meteorological year climate data, canyon air temperature microclimate model, and a whole-building energy simulation to investigate the impact of future microclimate conditions on a “typical” single-occupant office. Additionally, to capture the effects of building ...

Public Spending And Quality Of Education In Brazil., Monica A. Haddad, Ricardo Freguglia, Claudia Gomes 2017 Iowa State University

Public Spending And Quality Of Education In Brazil., Monica A. Haddad, Ricardo Freguglia, Claudia Gomes

Monica Haddad

We examined whether Brazil’s educational spending on public primary schools resulted in better quality of education, 2003-2009. Our hypothesis was municipalities that received higher government spending on primary education had higher students’ tests scores. We used a panel analysis with fixed effects, including a simulated instrumental variable to control for endogeneity. Even though the magnitude of all significant estimated coefficients increased, when controlling for endogeneity, they were still very small. Findings proved that the relationship between quality of education and educational spending was not optimal, weakly contributing to the increase in test scores.


The Ginkgo Shell, Mark Luzi, Karla Santos, Josh Cannon, Erika Davis, Nora Villanueva 2017 California Polytechnic State University, San Luis Obispo

The Ginkgo Shell, Mark Luzi, Karla Santos, Josh Cannon, Erika Davis, Nora Villanueva

Architectural Engineering

The overall concept for this outdoor concrete shell structure, located in Furstliche Park in Inzigkofen, Germany, is derived from an abstracted ginkgo leaf. Drawing on inspiration from a poem about the two parts of the ginkgo leaf becoming one, we took the approach of combining both the natural and built environment into one cohesive piece. To connect the two, it was imperative that we place the shell on the site as to have the smallest impact. With a small portion of the overall site used, the unoccupied space further enhances the natural environment. Creating a literal design connection between the ...


Implementing Subspace Identification On Shake Table Model, Zoe T. Cooperband 2017 California Polytechnic State University, San Luis Obispo

Implementing Subspace Identification On Shake Table Model, Zoe T. Cooperband

Architectural Engineering

Stochastic Subspace Identification is a field of applied mathematics that takes collected experimental time-history data and gives out information about the system that produced the data. SSI is typically used in control analysis but here we apply the methods to the modal analysis of structures. This senior project didn’t involve theory - instead much of the work was in research behind how Subspace Identification works, implementing the algorithm in MATLAB, and applying the program to shake table data to validate the program. In other words, building the framework to make SSI a usable tool and practical learning experience for other ...


Mano De La Amistad: A Thin Shell Concrete Structure Designed For The People Of Havana, Cuba, Peter Aster, Marta Blachowicz-Scott, Aaron Cook, Alex Erler, Elizabeth Townsend, Ger Yang 2017 California Polytechnic State University, San Luis Obispo

Mano De La Amistad: A Thin Shell Concrete Structure Designed For The People Of Havana, Cuba, Peter Aster, Marta Blachowicz-Scott, Aaron Cook, Alex Erler, Elizabeth Townsend, Ger Yang

Architectural Engineering

In designing a thin shell structure to cover the performance space on Tribuna Anti Imperialista Jose Marti, in Havana, Cuba, we developed a heavily symbolic concept and further abstracted it to reach our design. Basing the concept on the quote to the right by Obama about US and Cuba relations, we wanted our design to be representative of a hand that works to adjoin the plaza to the US Embassy which is directly west of the site. The “wrist” portion adds an asymmetric element, while the fingers provide a backdrop to the performers as well as a view through to ...

Acoustic Tweets And Blogs: Using Social Media In An Undergraduate Acoustics Course, Lily M. Wang 2017 University of Nebraska - Lincoln

Acoustic Tweets And Blogs: Using Social Media In An Undergraduate Acoustics Course, Lily M. Wang

Lily M Wang

Each fall, the author teaches an undergraduate architectural acoustics course to around 40 third-year architectural engineering students at the University of Nebraska. Beginning in 2011, a social media component was introduced to explore the use of this technology and how it may supplement the students' learning experience. Students were given an opportunity to receive extra credit by using Twitter and/or blogging about course material using a set hashtag (#AE3300) or through the course website. Results were positive, and the author will discuss pros and cons that she has experienced in adding this social media component. Suggestions for future implementations ...

A Need For Evidence-Based And Multidisciplinary Research To Study The Effects Of The Interaction Of School Environmental Conditions On Student Achievement, Josephine Lau, Lily M. Wang, Clarence Waters, James A. Bovaird

Lily M Wang

With funding from the U.S. Environmental Protection Agency’s (EPA) Healthy Schools initiative, a research team from the University of Nebraska– Lincoln (UNL) is currently working on establishing how environmental conditions in K-12 school buildings impact student scholastic achievement. The objectives of the research project are: (1) to study comprehensively the impacts of a wide set of indoor environmental factors (including indoor air quality, thermal, lighting and acoustic conditions) on student achievement; (2) to investigate how these environmental conditions interact with each other to impact student achievement; (3) to rank order the environmental variables in terms of their relative ...


Effects Of Reverberation And Noise On Speech Comprehension By Native And Non-Native English-Speaking Listeners, Z. Ellen Peng, Lily M. Wang, Siu-Kit Lau, Adam M. Steinbach 2017 University of Nebraska-Lincoln

Effects Of Reverberation And Noise On Speech Comprehension By Native And Non-Native English-Speaking Listeners, Z. Ellen Peng, Lily M. Wang, Siu-Kit Lau, Adam M. Steinbach

Lily M Wang

Previous studies have demonstrated the negative impact of adverse signal-to-noise-ratios on non-native English-speaking listeners' performance on speech recognition using recall tasks, as well as implied that comprehension skills were more impaired than recognition skills under reverberation and noise. The authors have themselves previously conducted a pilot study on three native and three non-native Englishspeaking listeners to examine the effects of reverberation and noise using speech comprehension tasks. Those results suggested that speech comprehension performance is worse under longer reverberation times (RT), and that a longer RT is more detrimental to speech comprehension by non-native listeners than native listeners. This paper ...


How Tonality And Loudness Of Noise Relate To Annoyance And Task Performance” Noise Control Eng. J. 65(2), 71-82., Joonhee Lee, Jennifer M. Francis, Lily M. Wang 2017 University of Nebraska - Lincoln

How Tonality And Loudness Of Noise Relate To Annoyance And Task Performance” Noise Control Eng. J. 65(2), 71-82., Joonhee Lee, Jennifer M. Francis, Lily M. Wang

Lily M Wang

Audible tones in noise generated by building mechanical equipment can be a leading cause of complaints from occupants. A number of metrics have been developed to quantify prominence of a tone, but previous work has shown that the impact of a certain tonality appears to vary with the level of the broadband noise signal. More work on how tonal signals of varying tonality, tone frequency and broadband noise levels relate to annoyance and task performance is needed. This paper investigates such relationships between current noise metrics, annoyance and task performance under assorted tonal noise conditions through subjective testing. Participants rated ...

Honors Theses AY 16/17

For architectural engineering, the senior project was to follow the design process for structural engineers while designing a portion of the addition to the Rochelle Athletics Center. It was the responsibility of myself and two other students to provide our interpretation and solution to the structural challenges that the addition posed. My responsibilities on this project included collaborative work in positioning the columns and designing the beam and girder layout. Once a general design was determined, each member of our group was responsible for calculating loads and capacities of members. Throughout the entire project, we had a collaborative effort to ...


Uncovering The Mystery Of Machu Picchu, Barbara Cardona 2017 Stanford University

Uncovering The Mystery Of Machu Picchu, Barbara Cardona

Butler Journal of Undergraduate Research

If mysteries were ranked, Machu Picchu would be on the top of the list. This Incan site, destination for millions of tourists, archaeologists and researchers each year, is one of the biggest enigmas of Incan culture. Its mesmerizing view has prompted hundreds of unanswered questions about this civilization. Incan culture revolved around cities, built without reference to the world beyond. Although the Incas were incredible architects and inventors, they lack written records, shrouding their culture in mystery for many years. While research has illuminated some facets of Incan culture, a significant question still remains: what purpose did Machu Picchu play ...


Rebuilding A Framework For Learning: Rethinking Structural Design Instruction In An Architectural Curriculum, Rob Whitehead 2017 Iowa State University

Rebuilding A Framework For Learning: Rethinking Structural Design Instruction In An Architectural Curriculum, Rob Whitehead

Rob Whitehead

Architectural design relies upon structural design principles to help gracefully resist the stresses of building elements that enclose spaces. This discipline and expertise of integration typically takes years to develop but unfortunately, instead of teaching these skills side-by-side with coordinated expectations for escalating levels of expertise, representation, and analysis, these courses have frequently been separated from each other in architectural curricula. The oppositional pedagogical methodologies and differential expectations for development that occur as a result of this have adverse consequences for student learning and practical preparedness. This paper, intended for a national target audience of university faculty and practitioners, will ...


Comprehensive And Creative Conclusions: Enhancing Structural Design Educational Opportunities In Labs For Architecture Students, Rob Whitehead 2017 Iowa State University

Comprehensive And Creative Conclusions: Enhancing Structural Design Educational Opportunities In Labs For Architecture Students, Rob Whitehead

Rob Whitehead

For decades, structural design has erroneously been taught to architecture students using a modified version of an engineering-based pedagogical model. Instead of imparting a broad range of information for how structural design considerations could be critically integrated into architectural design, these courses instead focus on a narrow range of curricular topics and analytical methods that negatively impact the preparedness of architectural students for practice. To help address these deficiencies, the entire building technology course sequence at Iowa State University, has been dramatically reconfigured as a collaborative and integrative teaching environment that uses active learning environments and unique classroom activities to ...


Saarinen’S Shells: The Evolution Of Engineering Influence, Rob Whitehead 2017 Iowa State University

Saarinen’S Shells: The Evolution Of Engineering Influence, Rob Whitehead

Rob Whitehead

This paper will examine the collaborative practice relationship between Eero Saarinen & Associates and Ammann & Whitney Engineers during their decade-long partnership in designing and documenting three concrete shell projects: Kresge Auditorium, TWA Terminal, and Dulles Airport Terminal. The variable range of the buildings’ formal expressions can be traced back to a corresponding level of involvement and influence from the structural engineers, resulting in a shift of Saarinen’s designs.
