The Right To The City. Towards The Dictatorship Of The Digital Proletariat In An Age Of Total Planetary Computation, David Capener

Conference papers

Alexa, turn on the hall lights.’ Words taken from a 2017 promotional video for the Amazon Echo —‘a disembodied voice’, and ‘interface for an extraordinarily complex set of information processing layers.’ ‘Alexa, do x’. The discounted toilet-roll is ordered or the house lights come on, but before they do, travelling at the speed of light, a small packet of data arrives at a banal warehouse in the middle of somewhere where needs, wants and desires are farmed in a repository of disembodied voices. From the mining of tantalum, used in the manufacturing of the Echo, from the geological strata of …

Investigating The State Of Play Of Geobim Across Europe, Claire Ellul, Jantien E. Stoter, Lars Harrie, M. Shariat, Avril Behan, Maria Pla

Conference papers

In both the Geographic Information (Geo) and Building Information Modelling (BIM) domains, it is widely acknowledged that the integration of data from both domains is beneficial and a crucial step in facing the multi-disciplinary challenges of our built environment. The result of this integration – which can broadly be termed GeoBIM – could answer questions such as identifying an appropriate Heating, Ventilation and Air Conditioning system for a building based on room usage, outside air temperature, solar exposure and traffic pollution or validating whether a proposed built asset meets relevant planning constraints.

Developing a coherent approach to GeoBIM integration requires …


Against The Grain: Why Is Timber Underutilised In The Irish Construction Industry Given Its Environmental Properties?, Francis Noel Duffy Jan 2018

Against The Grain: Why Is Timber Underutilised In The Irish Construction Industry Given Its Environmental Properties?, Francis Noel Duffy

Other resources

This study explores why timber is underutilised in the Irish construction industry, given its environmental properties. Defined literature discourse (framed by two timber exemplar case study buildings and themed into procurement, policy and academic sections) is analysed in pursuit of factors that meet the research question. The literature data collected is used to formulate action-based research in the form of a “Wood First” motion, subsequently passed into policy by South Dublin County Council in July 2017. The literature is also refined into questions for a two-stage, fourth-generation evaluation interview process. This process further examines the discourse of industry experts and …

Neighborhood Variation Of Sustainable Urban Morphologicalcharacteristics, P. C. Lai, Sissi Si Chen, C. T. Low, Ester Cerin, Robert Stimson, Py Paulina Wong

Faculty of Design & Environment (THEi)

Compact cities and their urban forms have implications on sustainable city development because of high density urban settlement, increased accessibility, and a balanced land use mix. This paper uses quantitative means of understanding urban morphological characteristics with reference to the differing qualities of the urban form (i.e., street patterns, building volumes, land uses and greenery). The results, based on 89 neighborhood communities of Hong Kong, show varying degrees of regional differences in the urban built form supported by numerical statistics and graphical illustrations. This paper offers empirical evidence on some morphological characteristics that can be estimated objectively using modern geospatial …

Quality Of Life In A “High-Rise Lawless Slum”: A Study Of The Kowloon Walled City, Prudencea Leung Kwok Lau, Lawrenceb Wai Chung Lai, Daniel Chi Wing Ho

Faculty of Design & Environment (THEi)

Informed by the ‘quality of life’ model with specific reference to Chinese culture, this article uses reliable and publicly available information seldom used in historical or heritage study to identify the designs of flats and builders of the “Kowloon Walled City” (hereafter the City) and reliable oral testimonies to refute some myths about the quality of life within it. This settlement has been notoriously misrepresented by some as a city of darkness that was razed from the face of the Earth before 1997 to fulfill a pre-war dream of the colonial government. This article confirms the view that this extremely …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Polychlorinated biphenyl (PCB) contamination of buildings continues to pose an exposure threat, even decades after their application in the form of calks and other building materials. In this research, we investigate the ability of clothing to sorb PCBs from contaminated air and thereby influence exposure. The equilibrium concentration of PCB-28 and PCB-52 was quantified for nine used clothing fabrics exposed for 56 days to air in a Danish apartment contaminated with PCBs. Fabric materials included pure materials such as cotton and polyester, or blends of polyester, cotton, viscose/rayon, and/or elastane. Air concentrations were fairly stable over the experimental period, with …

Draft Programmatic Agreement For Buildings And Structures At Cold War Era Dedicated Instrumentation Sites: White Sands Missile Range, New Mexico, Phillip S. Esser

Historic Preservation Capstone Projects

Since 1966, when the National Historic Preservation Act (NHPA) was signed into law, federal agencies have been required to consider their impact to known or potential historic resources under their jurisdiction. As a potentially costly and onerous process for large government installations such as the military, the law allows for procedures known as “program alternatives” which allow federal agencies to streamline the requirements for inventorying and evaluating categories of, or similar resources (in this case, buildings and structures) for their potential as historic resources.

This Capstone project seeks to capture a category of such resources, building and structures at Cold …

Identifying, Explaining, And Rethinking Gentrification, Minkyu Yeom

ETD Archive

This dissertation is composed of three essays. The three essays have different topics, research questions, methods, and conclusions. The first essay focused on how to identify gentrified areas. This dissertation employed census tract data of the urbanized areas within 12 metropolitan statistical areas in the United States of America to identify gentrified census tracts. To discern gentrified census tracts, this dissertation created the Gentrification Index which is composed of Neighborhood Transformation Index and Displacement Index. Among 12,803 total census tracts, 11,690 census tracts (91.31%) have been identified as no gentrification, 843 (6.58%) census tracts have been recognized as somewhat gentrified, …


Venezuela Public Health Issue, Luke Vargas Jan 2018

Venezuela Public Health Issue, Luke Vargas

Global Public Health

While every country around the world faces a form of public health issues, the issues that the country of Venezuela faces are different. Their public health problem is not a disease that can be solved by science, or a cure. It’s a problem that can only be solved by the people within the county itself. The country of Venezuela now lacks the proper medical supplies needed to help cure diseases and normal vaccinations, and the only ones to blame is their government. Because their government has now refused to pay their debts to the surrounding countries they have now lost …


Locating The Memory Of Political Genocide In The Tradition Of Peace: Two Documentation Centers Of Nazism In Germany, Rumiko Handa Jan 2018

Locating The Memory Of Political Genocide In The Tradition Of Peace: Two Documentation Centers Of Nazism In Germany, Rumiko Handa

Architecture Program: Faculty Scholarly and Creative Activity

How can architectural design assist in making the past present in meaningful ways when applied to buildings that commemorate troubling pasts? This dilemma becomes even more challenging when a preexisting building is located in a district that had provided citizens with a peaceful setting for leisurely activities before it was taken over for politically hostile purposes. Once that evil force has been eliminated, both city authorities and citizens may desire to return the district to its distant past, bringing peace back to the area. Yet they may also desire that the building carry their difficult memories of the more immediate …

Prosocial Religion And Games: Lost & Found, Owen Gottlieb, Ian Schreiber Jan 2018

Prosocial Religion And Games: Lost & Found, Owen Gottlieb, Ian Schreiber

Articles

In a time when religious legal systems are discussed without an understanding of history or context, it is more important than ever to help widen the understanding and discourse about the prosocial aspects of religious legal systems throughout history. The Lost & Found (www.lostandfoundthegame.com) game series, targeted for an audience of teens through twentysomethings in formal, learning environments, is designed to teach the prosocial aspects of medieval religious systems—specifically collaboration, cooperation, and the balancing of communal and individual/family needs. Set in Fustat (Old Cairo) in the 12th century, the first two games in the series address laws in Moses Maimonides’ …


Could Autodesk Revit Be Automated For Code Compliance Checking And Demonstration With A Focus On Fire Safety Regulations?, Ross Harrell, Malachy Mathews Jan 2018

Could Autodesk Revit Be Automated For Code Compliance Checking And Demonstration With A Focus On Fire Safety Regulations?, Ross Harrell, Malachy Mathews

Reports

Often a subject to ambiguity and interpretation, building codes and compliance with them require years of expertise to understand and to integrate into good design. Automation of code compliance through Building Information Modelling (BIM) removes the human aspect from these processes and ensures building codes are correctly adhered to. In this paper, the author reviews current code compliance systems implemented internationally and, with a focus on fire codes, compares them to the current fire certificate application in The Republic of Ireland. By conducting interviews with an Executive Fire Prevention Officer of Dublin Fire Brigade and a Fire Consultant practicing in …


Design And Manufacture Of A Precast Pcm Enhanced Concrete Cladding Panel For Full Scale Performance Monitoring, Dervilla Niall, Roger West, Oliver Kinnane Jan 2018

Design And Manufacture Of A Precast Pcm Enhanced Concrete Cladding Panel For Full Scale Performance Monitoring, Dervilla Niall, Roger West, Oliver Kinnane

Conference papers

The overall aim of this study is to develop innovative precast cladding panels for the renovation of Europe’s existing building stock thereby improving their energy performance. Using the mass of a building to store heat and/or cold can reduce the demand on the auxiliary heating and/or cooling systems and hence reduce the overall energy demand of the building. Previous laboratory research has shown that the incorporation of phase change materials (PCMs) into concrete enhances its thermal storage capacity by up to 50%. However in a real application where a PCM-concrete composite material is used in a building to store thermal …

W. G. Sebald’S Austerlitz : Architecture As A Bridge Between The Lost Past And The Present, Rumiko Handa Jan 2018

W. G. Sebald’S Austerlitz : Architecture As A Bridge Between The Lost Past And The Present, Rumiko Handa

Architecture Program: Faculty Scholarly and Creative Activity

Architecture has a way of bringing the past to the present for us. It is an important asset, for the experience of the past constitutes a positive moment in our everyday conduct of life, allowing a contemplation on our existential meaning. It is an often neglected aspect, as it lies outside of architecture's aesthetic, functional, or structural realms. Mechanisms at work in effectuating this feature can vary, among which the following are notable: A building may commemorate a particular event or individual by being a monument. A building may refer to the time of its origin by way of its …


Using Virtual Reality And Photogrammetry To Enrich 3d Object Identity, Cole Juckette, Heather Richards-Rissetto, Hector Eluid Guerra Aldana, Norman Martinez Jan 2018

Using Virtual Reality And Photogrammetry To Enrich 3d Object Identity, Cole Juckette, Heather Richards-Rissetto, Hector Eluid Guerra Aldana, Norman Martinez

Department of Anthropology: Faculty Publications

The creation of digital 3D models for cultural heritage is commonplace. With the advent of efficient and cost effective technologies archaeologists are making a plethora of digital assets. This paper evaluates the identity of 3D digital assets and explores how to enhance or expand that identity by integrating photogrammetric models into VR. We propose that when a digital object acquires spatial context from its virtual surroundings, it gains an identity in relation to that virtual space, the same way that embedding the object with metadata gives it a specific identity through its relationship to other information. We explore this concept …
