Wall Panel Optimization For Refugee Shelters In Germany: An Ahp Study, Zhu Jiadong 2017 Western Kentucky University

Wall Panel Optimization For Refugee Shelters In Germany: An Ahp Study, Zhu Jiadong

Masters Theses & Specialist Projects

The German government is experiencing difficulties housing and assimilating Syrian refugees in its borders. Erecting temporary shelters on location is one way to deal with the current crises. This thesis attempts to use Analytic Hierarchy Process (AHP) to determine the optimum combination of materials and construction methods to be used in the shelter’s walls in order to improve the living conditions of the refugees and to ensure that the cost is acceptable to the German government. This thesis compares six existing wall panel products from China, which have the lowest cost on the worldwide market. The R-value, strength, price ...


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

Architectural Engineering -- Faculty Publications

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 ...

Architectural Engineering

The project explores the relationship between the architecture and the engineering behind thin-shelled concrete structures. Initially, hanging chain models were used to observe pure compression; then, this model was improved upon using software like Rhinocerus, AutoCAD. From AutoCAD, the model was imported into SAP2000 for analysis.


Lateral Strength And Ductile Behavior Of A Mortise-Tenon Connected Timber Frame, Alexandros Kouromenos 2017 California Polytechnic State University, San Luis Obispo

Lateral Strength And Ductile Behavior Of A Mortise-Tenon Connected Timber Frame, Alexandros Kouromenos

Master's Theses and Project Reports

The primary goals of this project were to examine the amount of lateral force resisted by a single-bay mortise-tenon connected timber moment frame, and to introduce ductile behavior into the mortise-tenon connections by adding a steel sleeve around a traditional wood peg. This research aimed to provide proof that traditional timber frames are capable of ductile racking while reliably complying with ASCE 7-10 building code drift speci! cations, implying an increase in the ASCE 7-10 ductility factor (R) for wood frames when used as lateral force resisting elements. A secondary goal was to promote traditional heavy timber framing as a ...

Irish Bim Study 2017, Barry Mcauley, Alan Hore, Roger West

Articles

The Construction IT Alliance (CitA) recently published its Global BIM Study as part of its BIM Innovation Capability Programme (BICP). The study sought to identify how BIM was being currently addressed in 27 countries across the globe. The study sought to identify the presence of three key ingredients in these countries:

1. Regulatory requirement for BIM

2. Champions driving BIM

3. Noteworthy publications

The report identified a number of recurring themes that would help to shape Ireland’s BIM programme. The report concluded that Ireland should adopt a programme of partnership between industry and the Irish Government in order to ...

Bicp Global Bim Study - Lessons For Ireland’S Bim Programme, Barry Mcauley, Alan Hore, Roger West

Reports

The Construction IT Alliance (CitA) has been promoting the benefits of digitisation in the construction and engineering industry in Ireland since its formation back in 2002. Whilst the Alliance has always strived to ensure that its members are exposed to a wide spectrum of contemporary digital tools and processes, the concept of Building Information Modelling (BIM) has dominated the focus of its activities over the past five years.

BIM can be described as a digital tool that facilitates everybody to better understand a building or structure through the use of a digital model which draws on a range of data ...

Architecture is now more than ever dominated by scientific method. This paper examines what is really at stake when designing sustainable architecture. It is a methodological study and focused on science as understood in Post Occupancy Evaluation (POE) of sustainable buildings, specifically school buildings. Questions raised in this paper include the very real problem of designing for children’s comfort and education in school architecture, but also much wider issues than simply those of the design of children’s environments.

Development Of A Simplified Heat And Moisture Transfer Model For Residential Buildings, Joowook Kim 2017 University of Colorado at Boulder

Development Of A Simplified Heat And Moisture Transfer Model For Residential Buildings, Joowook Kim

Civil Engineering Graduate Theses & Dissertations

A large number of building energy simulation programs are used to evaluate indoor conditions and energy performance of buildings. Every building energy modeling tool calculates the heat and moisture exchange among the outdoor environment, the building envelope, and indoor environments as a fundamental component of heating, ventilating, and air conditioning (HVAC) loads. While all tools account for moisture flow through the envelope by infiltration, almost no users calculate moisture diffusion through the envelope or moisture storage in the building due to excessive computation time and unavailable material properties. However, research has shown, and work in this dissertation has confirmed, that ...

Study On The Methods For Predicting The Performance Of A Hybrid Solar-Assisted Ground-Source Heat Pump System, Zhaoyi Zhuang, Qiqi Zhu, Jian Song, Xin Zhang, Haorong Li

Architectural Engineering -- Faculty Publications

It is critical to find suitable setting parameters for designing a hybrid solar-assisted ground-source heat pump system in the practical engineering application, but the heat pump performance is unpredictable after many years of operation. This paper used 2000 sets of performance data collected from solar-assisted GSHP systems that keep operating over 20 years to simulate long term used heat pump with a professional software called GeoStar. Adopted the classification and regression tree (CART) method, the design of solar energy collector areas can be predicted. The multi-linear regression is also utilized to predict average monthly per meter borehole heat exchange. Seasonal ...

Mechanical Engineering Faculty Contributions

The objectives of this study were to measure levels of particulate matter (PM) in mechanically ventilated buildings and to improve understanding of filtration requirements to reduce exposure. With the use of an Ultra High Sensitivity Aerosol Spectrometer and an Aerodyne Mass Spectrometer, ultrafine (0.055–0.1 μm) and fine (0.1–0.7 μm) indoor and outdoor PM was measured as a function of time in an office, a university building, and two elementary schools. Indoor particle levels were highly correlated with outdoor levels. Indoor and outdoor number concentrations in Denver were higher than those in Boulder, with the ...


Energy Performance Anlaysis Of Transparent Wood Composite-Based Glazing Systems In Commerical Buildings, Joseph Hoberg Arehart 2017 University of Colorado at Boulder

Energy Performance Anlaysis Of Transparent Wood Composite-Based Glazing Systems In Commerical Buildings, Joseph Hoberg Arehart

Civil Engineering Graduate Theses & Dissertations

Transparent wood composites (TWCs) have 15% the thermal conductivity of silicon-based glass and can be used in alternative glazing systems. Single-paned and double-paned TWC based window assemblies were developed for implementation in commercial reference buildings of three vintages (Pre-1980, Post-1980, and Post-2004) located in 15 climate zones. Energy simulations were performed for baseline buildings and compared against buildings with TWC based glazing systems in place of traditional glass based glazing. In addition, a cost analysis was performed for lab-scale production of TWCs. Results showed that buildings with TWC based windows reduced space conditioning by up to 33.3%. Commercial buildings ...
